ARC WELDING SAFETY INSTRUCTIONS AND WARNINGS
Instruction 830001
ARC WELDING can be hazardous.
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER
WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR. DO NOT LOSE THESE INSTRUCTIONS. READ OPERATING/INSTRUCTION MANUAL BEFORE INSTALLING, OPERATING OR SERVICING THIS EQUIPMENT.
Welding products and welding processes can cause serious injury or death, or damage to other equipment or property, if the operator does
not strictly observe all safety rules and take precautionary actions.
Safe practices have developed from past experience in the use of welding and cutting. These practices must be learned through study and
training before using this equipment. Anyone not having extensive training in welding and cutting practices should not attempt to weld. Certain
of the practices apply to equipment connected to power lines; other practices apply to engine driven equipment.
Safe practices are outlined in the American National Standard Z49.1 entitled: SAFETY IN WELDING AND CUTTING. This publication and
other guides to what you should learn before operating this equipment are listed at the end of these safety precautions.
HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY QUALIFIED PEOPLE.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. In semiautomatic or automatic
wire welding, the wire, wire reel, drive roll housing,
and all metal parts touching the welding wire are
electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats
or covers.
4. Disconnect input power or stop engine before installing or servicing this equipment. Lock input power disconnect switch open,
or remove line fuses so power cannot be turned on accidentally.
5. Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
ARC RAYS can burn eyes and skin;
NOISE can damage hearing.
Arc rays from the welding process produce intense
heat and strong ultraviolet rays that can burn eyes
and skin. Noise from some processes can damage
hearing.
6. Turn off all equipment when not in use. Disconnect power to
equipment if it will be left unattended or out of service.
7. Use fully insulated electrode holders. Never dip holder in water
to cool it or lay it down on the ground or the work surface. Do not
touch holders connected to two welding machines at the same
time or touch other people with the holder or electrode.
8. Do not use worn, damaged, undersized, or poorly spliced cables.
9. Do not wrap cables around your body.
10. Ground the workpiece to a good electrical (earth) ground.
11. Do not touch electrode while in contact with the work (ground)
circuit.
12. Use only well-maintained equipment. Repair or replace damaged
parts at once.
13. In confined spaces or damp locations, do not use a welder with
AC output unless it is equipped with a voltage reducer. Use
equipment with DC output.
14. Wear a safety harness to prevent falling if working above floor
level.
15. Keep all panels and covers securely in place.
1. Wear a welding helmet fitted with a proper shade of filter (see
ANSI Z49.1 listed in Safety Standards) to protect your face and
eyes when welding or watching.
2. Wear approved safety glasses. Side shields recommended.
3. Use protective screens or barriers to protect others from flash
and glare; warn others not to watch the arc.

Instruction 830001
FUMES AND GASES can be hazardous
to your health.
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breath the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the manufacturer’s instruction for metals, consumables, coatings, and
cleaners.
5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Shielding gases used for
welding can displace air causing injury or death. Be sure the
breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
7. Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
weld area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if welded.
WELDING can cause fire or explosion.
5. Watch for fire, and keep a fire extinguisher nearby.
Sparks and spatter fly off from the welding arc. The
flying sparks and hot metal, weld spatter, hot workpiece, and hot equipment can cause fires and burns.
Accidental contact of electrode or welding wire to
metal objects can cause sparks, overheating, or fire.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the welding arc.
If this is not possible, tightly cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
FLYING SPARKS AND HOT METAL can
cause injury.
Chipping and grinding cause flying metal. As welds
cool, they can throw off slag.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas
cylinders are normally part of the welding process,
be sure to treat them carefully.
1. Protect compressed gas cylinders from excessive heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position by chaining
them to a stationary support or equipment cylinder rack to prevent
falling or tipping.
7. Do not weld on closed containers such as tanks or drums.
8. Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
11. Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
1. Wear approved face shield or safety goggles. Side shields recommended.
2. Wear proper body protection to protect skin.
3. Keep cylinders away from any welding or other electrical circuits.
4. Never allow a welding electrode to touch any cylinder.
5. Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
6. Turn face away from valve outlet when opening cylinder valve.
7. Keep protective cap in place over valve except when cylinder is
in use or connected for use.
8. Read and follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-1 listed in Safety
Standards.
ENGINES can be hazardous.
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
2-2
1. Use equipment outside in open, well-ventilated areas.
2. If used in a closed area, vent engine exhaust outside and away
from any building air intakes.
May 8, 1996
Instruction 830001
ENGINE FUEL can cause fire or
explosion.
Engine fuel is highly flammable.
1. Stop engine before checking or adding fuel.
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
1. Keep all doors, panels, covers, and guards closed and securely
in place.
2. Stop engine before installing or connecting unit.
SPARKS can cause BATTERY GASES
TO EXPLODE; BATTERY ACID can
burn eyes and skin.
Batteries contain acid and generate explosive gases.
STEAM AND PRESSURIZED HOT
COOLANT can burn face, eyes, and
skin.
The coolant in the radiator can be very hot and under
pressure.
2. Do not add fuel while smoking or if unit is near any sparks or open
flames.
3. Allow engine to cool before fueling. If possible, check and add
fuel to cold engine before beginning job.
4. Do not overfill tank — allow room for fuel to expand.
5. Do not spill fuel. If fuel is spilled, clean up before starting engine.
3. Have only qualified people remove guards or covers for maintenance and troubleshooting as necessary.
4. To prevent accidental starting during servicing, disconnect negative (-) battery cable from battery.
5. Keep hands, hair, loose clothing, and tools away from moving
parts.
6. Reinstall panels or guards and close doors when servicing is
finished and before starting engine.
1.

3.
4.
5.
Always wear a face shield when working on a battery.
Stop engine before disconnecting or connecting battery cables.
Do not allow tools to cause sparks when working on a battery.
Do not use welder to charge batteries or jump start vehicles.
Observe correct polarity (+ and –) on batteries.
1. Do not remove radiator cap when engine is hot. Allow engine to
cool.
2. Wear gloves and put a rag over cap area when removing cap.
3. Allow pressure to escape before completely removing cap.
WARNING: This product, when used for welding or cutting, produces fumes or gases which contain chemicals known to the State
of California to cause birth defects and, in some cases, cancer.
(California Health & Safety Code Sec. 25249.5 et seq.)
NOTE: Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the U.S. Congress, Office of Technology Assessment, Biological Effects
of Power Frequency Electric & Magnetic Fields — Background Paper, OTA-BP-E-63 (Washington, DC: U.S. Government Printing Office, May
1989): “... there is now a very large volume of scientific findings based on experiments at the cellular level and from studies with animals and
people which clearly establish that low frequency magnetic fields can interact with, and produce changes in, biological systems. While most of
this work is of very high quality, the results are complex. Current scientific understanding does not yet allow us to interpret the evidence in a
single coherent framework. Even more frustrating, it does not yet allow us to draw definite conclusions about questions of possible risk or to
offer clear science-based advice on strategies to minimize or avoid potential risks.”
To reduce magnetic fields in the workplace, use the following procedures:
1. Keep cables close together by twisting or taping them.
3. Do not coil or drape cables around the body.
2. Arrange cables to one side and away from the operator.
4. Keep welding power source and cables as far away from body as
practical.
About Pacemakers:
The above procedures are among those also normally recommended for pacemaker wearers. Consult your doctor for complete information.

LES VAPEURS ET LES FUMEES SONT
DANGEREUSES POUR LA SANTE.
Le soudage dégage des vapeurs et des fumées
dangereuses à respirer.
1. Eloignez la tête des fumées pour éviter de les respirer.
2. A l’intérieur, assurez-vous que l’aire de soudage est bien ventilée ou que les fumées et les vapeurs sont aspirées à l’arc.
3. Si la ventilation est inadequate, portez un respirateur à adduction d’air approuvé.
4. Lisez les fiches signalétiques et les consignes du fabricant
relatives aux métaux, aux produits consummables, aux revêtements et aux produits nettoyants.

5. Ne travaillez dans un espace confiné que s’il est bien ventilé;
sinon, portez un respirateur à adduction d’air. Les gaz protecteurs de soudage peuvent déplacer l’oxygène de l’air et ainsi
causer des malaises ou la mort. Assurez-vous que l’air est
propre à la respiration.
6. Ne soudez pas à proximité d’opérations de dégraissage, de
nettoyage ou de pulvérisation. La chaleur et les rayons de l’arc
peuvent réagir avec des vapeurs et former des gaz hautement
toxiques et irritants.
7. Ne soudez des tôles galvanisées ou plaquées au plomb ou au
cadmium que si les zones à souder ont été grattées à fond, que
si l’espace est bien ventilé; si nécessaire portez un respirateur
à adduction d’air. Car ces revêtements et tout métal qui contient
ces éléments peuvent dégager des fumées toxiques au moment
du soudage.

LE SOUDAGE PEUT CAUSER UN INCENDIE OU UNE EXPLOSION
L’arc produit des étincellies et des projections. Les
particules volantes, le métal chaud, les projections
de soudure et l’équipement surchauffé peuvent
causer un incendie et des brûlures. Le contact
accidentel de l’électrode ou du fil-électrode avec un
objet métallique peut provoquer des étincelles, un échauffement
ou un incendie.
1. Protégez-vous, ainsi que les autres, contre les étincelles et du
métal chaud.
2. Ne soudez pas dans un endroit où des particules volantes ou
des projections peuvent atteindre des matériaux inflammables.
3. Enlevez toutes matières inflammables dans un rayon de 10, 7
mètres autour de l’arc, ou couvrez-les soigneusement avec des
bâches approuvées.
LES ETINCELLES ET LES PROJECTIO N S BRU LA NTES PEU V EN T
CAUSER DES BLESSURES.
LES BOUTEILLES ENDOMMAGEES
PEUVENT EXPLOSER
Les bouteilles contiennent des gaz protecteurs
sous haute pression. Des bouteilles endommagées
peuvent exploser. Comme les bouteilles font normalement partie du procédé de soudage, traitezles avec soin.
1. Protégez les bouteilles de gaz comprimé contre les sources de
chaleur intense, les chocs et les arcs de soudage.
2. Enchainez verticalement les bouteilles à un support ou à un
cadre fixe pour les empêcher de tomber ou d’être renversées.
3. Eloignez les bouteilles de tout circuit électrique ou de tout
soudage.
4. Méfiez-vous des projections brulantes de soudage susceptibles
de pénétrer dans des aires adjacentes par de petites ouvertures
ou fissures.
5. Méfiez-vous des incendies et gardez un extincteur à portée de
la main.
6. N’oubliez pas qu’une soudure réalisée sur un plafond, un
plancher, une cloison ou une paroi peut enflammer l’autre côté.
7. Ne soudez pas un récipient fermé, tel un réservoir ou un baril.
8. Connectez le câble de soudage le plus près possible de la zone
de soudage pour empêcher le courant de suivre un long parcours inconnu, et prévenir ainsi les risques d’électrocution et
d’incendie.
9. Ne dégelez pas les tuyaux avec un source de courant.
10. Otez l’électrode du porte-électrode ou coupez le fil au tube-contact lorsqu’inutilisé après le soudage.
11. Portez des vêtements protecteurs non huileux, tels des gants
en cuir, une chemise épaisse, un pantalon revers, des bottines
de sécurité et un casque.
Le piquage et le meulage produisent des particules métalliques
volantes. En refroidissant, la soudure peut projeter du éclats de
laitier.
1. Portez un écran facial ou des lunettes protectrices approuvées.
Des écrans latéraux sont recommandés.
2. Portez des vêtements appropriés pour protéger la peau.
4. Empêchez tout contact entre une bouteille et une électrode de
soudage.
5. N’utilisez que des bouteilles de gaz protecteur, des détendeurs,
des boyauxs et des raccords conçus pour chaque application
spécifique; ces équipements et les pièces connexes doivent
être maintenus en bon état.

General Description
The Model 2460 Heavy Duty CC/CV Wire Feeder
is designed to control the linear movement of 1/8
inch (3.2 mm) diameter (or less) tubular welding
electrode or 3/32 inch diameter (or less) solid welding electrode. The basic feeder has been designed
for self-shielding welding electrode and does not
have a gas solenoid.
For use of non self-shielding electrode, optional
gas solenoids are available and may be installed in
this portable feeder.
Metal Inert Gas (MIG) welding process joins metal
parts by electric arc which is established between a
filler metal (consumable welding wire) and the work.
The combination of the consumable wire with the
parent metal forms the weld.
This wire feeder may be used with either a constant-voltage or constant-current type welding machine. A transformer-rectifier, motor-generator, or
engine-driven welding machine may be used.
Current Capacity and Rating
The welding current on this equipment is passed
through the feedhead assembly. Care must be
taken to make sure that the connections between
the feedhead and the power source connecting
cable as well as between the feedhead and gun
cable assembly connector are tight. Loose connections cause excessive heating and must be avoided.
This feeder uses arc voltage for its power. The
cable connection between the feedhead and the
power source also provide a power connection for
the feeder control. The other power connection is
made through the voltage sensing lead which must
be connected to the work terminal. Care must be
taken to make sure that the power cable connection
is made between the power source and work. If this
connection is not made, and an attempt is made to
strike an arc, serious damage to the feeder will
occur. By taking power from the welding arc, two
modes of operation result. These are termed CC
and CV mode. When a constant voltage power
source is used, the input voltage to the feeder
remains constant and a fixed wire feed speed will
result for a given dial selection on the feeder. If either
the power source voltage setting or the feeder setting are changed, the output speed will change. This
is called CV mode of operation. When a constant
May 22, 1997 Revised
current power source is used, the arc voltage will
vary and as a result, the wire feed speed will vary
for a fixed dial setting on the feeder. This is called
CC mode of operation. When a constant current
power source is used, an increase in arc voltage will
cause an increase in wire feed speed, but an increase in wire feed speed causes a decrease in arc
voltage. This results in a self-regulating system so
that the feeder keeps the arc voltage constant by
varying the wire feed speed as the arc attempts to
fluctuate. A switch on the back of the feeder is
provided to select between CV or CC. This switch
selects proper control stability for the mode being
used. The switch does not select the mode of
operation. The mode of operation is determined by
the type of power source being used.
The main application for this wire feeder is for CC
application using tubular self-shielding wires. Most
CC types of power sources do not have a remote
contactor control available. This means that the
electrode is always hot once the power source has
been turned on. It also means that the gun switch
on the wire feeder does not control the power
source, but only controls the starting and stopping
of the wire feeder itself. Since the power source
remains turned on, when the gun switch is released,
care must be taken when terminating the arc. When
the gun switch is released, the operator must also
pull the gun away from the arc to make sure that the
arc is extinguished and does not burn back into the
gun tip.
Internal limiting circuitry limits the maximum speed
independent of input voltage. In addition, a slow
run-in circuit is provided which automatically reduces the run in wire feed speed when open circuit
voltage from a CC power source is present.
NOTE: Wire feeder input is protected by a
7 Amp slo-blow fuse. An 1/8 Amp fuse
protects the P.C. Board circuitry should a
short develop between the gun switch lead
to electrode lead. A 5 Amp slo-blow in-line
fuse inside the case protects the wire feed
motor.
Feedhead Assembly
The feed roll drive motor is solid-state controlled
on this unit. One of either of two different motors
(see Parts List for numbers of each) are used,

OPERATION
OPERATION
Prewelding Checks
Before attempting to operate the Model 2460
Heavy Duty CC/CV Wire Feeder, make certain that
all installation instructions, including those for the
welding machine (power source), and the welding
gun and cable, have been carried out.
1. With the feeder properly connected to the power
source and the work cables properly connected
from power source to work and from feeder to work,
turn on the power source.
WARNING: When the power
source is turned on, the electrode (welding wire) is electrically “hot”. Do not permit it to
touch any metal or a welding arc
may be established which may
be injurious to someone’s eyes
(flash) or skin (burn).
2. Select CC/CV characteristic on motor control
circuit and set switch accordingly.
3. Determine desired operating voltage in case of
a CV power source or desired operating current in
case of a CC power source and set power source
accordingly.
4. Set control on feeder to an approximate 3
position on the dial.
NOTE: When using a CV power source,
increasing dial position will increase wire
feed speed and as a result increase welding current.
When using a CC power source, increasing
dial position will increase wire feed speed
and as a result will decrease arc voltage.
Welding
1. Position the gun above the workpiece but do not
touch the electrode to the work as this will cause arc
flash. With the gun in the proper position and eyes
fully protected, pull the gun switch which will cause
an arc to be initiated.
2. Releasing the gun switch trigger will cause the
wire to stop feeding. At this time the gun must be
pulled away from the work in order to extinguish the
arc.
3. When the welding has been completed, or at the
end of the work day, it is recommended that the
power source and feeder be turned off.

TIP-218
DESCRIPTION, INSTALLATION, OPERATION AND MAINTENANCE
Description
The Control Box assembly is the control medium
for the operation of the Feedhead. Wire Feed Speed
rate (IPM Inches-per-minute) is selected and regulated by the knob (potentiometer) on the front panel.
The box is designed to function as a component of
the 2000 Series Wire Feeder composite assembly,
or as remote-mounted control medium, not situated
close to the Feedhead. A side panel is available to
replace the Feedhead Mounting Plate (see Figure
1) when used in a remote situation.
Controls and Connections
A. CV operation. When using a CV power source,
this control is used to control wire feed speed. To
increase wire feed speed, turn the control knob
clockwise. To decrease wire feed speed, turn the
knob counterclockwise.
B. CC operation. When using a CC power source,
this control is used to control arc voltage by varying
wire feed speed. To increase arc voltage (decrease
wfs), turn knob counterclockwise. To decrease arc
voltage (increase wfs), turn knob clockwise.
NOTE: Many CC power sources have a
drooping V-I characteristic. On these
types of power sources, the current is not
exactly constant and changing the arc
voltage will also change the output current. This again becomes a self-regulating stable system.
ON-OFF Rocker Switch — This switch controls the
input circuit, applying or removing the input voltage
of the unit.
Gun Switch Receptacle — The gun switch control
cable connects to the gun switch receptacle (quickdisconnect type) to provide control from the gun
switch to the wire feed mechanism.
Welding Gun Cable Connector — The gun cable
is connected to the wire feeder at this receptacle.
Connections must always be tight.
Fuse 7 A — The unit is equipped with a 7 A MDX
slow blow fuse. This fuse is rated at 125 volt and
may never be replaced with a fuse of lower voltage
rating as this could cause serious damage to the
equipment.
Fuse 1/8 A — Protects P.C. Board from welding
electrode shorting to gun switch circuit.
Figure 1 Controls - Connections (Front End)
Page 1
TIP-218
Figure 2 Connections (Rear End of Enclosure)
Fuse 5 A — Protects motor from excessive stall
current.
Label — Identifies 5 A fuse rating and location
(inside control box).
CC/CV Switch — This is a two-position switch that
controls the droop characteristics of the motor control circuit. When in the CV position, the circuit uses
IR compensation giving an almost flat speed torque
curve. When in the CC position, the IR compensation is eliminated and the speed torque curve has a
fairly high droop. The CV position is recommended
for all CV types of power sources. The CC position
is generally recommended when using a CC power
source. For many types of wires however, the CV
position is recommended even when a CC power
source is used.
A 12-volt gas valve and P.C. Board control the
shielding gas for solid wire welding. Welding gas will
flow when the gun switch is closed.
The circuit board uses the output voltage of the
bridge rectifier CR1 and converts this output into a
12-V DC voltage. The gas valve is a part of the total
Page 2
DC to DC converter circuit and is always connected
in the circuit.
The circuit board is installed next to the motor
control board.
Installation
Location
The model 2460 heavy duty CC/CV wire feeder is
designed to withstand high moisture conditions encountered in outdoor welding applications. However, the wire feeder is not waterproof and therefore
should not be stored outdoors for extended periods
of time.
Connections
1. Make sure that the proper welding cable connections exist between the feeder feedhead (electrode) to power source and work connection to
power source. Connect Feeder work lead (Figure 1)
to work.
TIP-218
voltage and changes it to the proper DC voltage
2. Attach the gun and cable to the wire feeder by
required to operate the motor. The motor is part of
following instructions found in the Owner’s Manual
the operating circuit, and the circuit will not operate
for the Gun and Cable assembly.
properly if the motor is removed.
WARNING: The welding electrode is electrically “Hot”. Electrode contact to workpiece will
cause an arc with the wire feeder
connected to the workpiece and
gun switch depressed — feed
motor will run feeding “HOT”
electrode.
Operation
Theory of Operation
Refer to Connection Diagram 376784A
With the wire feeder connected to the welding
electrode and the work terminal, turn the power
source and wire feeder on. Power is supplied into
Bridge rectifier CR1. Power on the output side of the
CR1 is fed to the motor control board with the proper
polarity independent of the welding polarity.
When the welding gun switch (S4) is closed, it
energizes the proper components on the PC Board
and causes the motor to run. When the gun switch
is opened, it removes power from the motor and
shorts the armature to provide dynamic braking of
the motor.
When the CC/CV switch (S5) is open, IR compensation is used on the motor control circuit. When S5
is closed, the IR compensation circuit is not active.
The circuit is designed for continuous operation
when the input voltage is 30 volts or below. Many
CC power sources have an open circuit voltage of
60 to 100 volts. Under these input conditions, the
circuit will operate and the motor will run. This
condition may exist for a period long enough to feed
wire through the gun when wire spools are changed,
etc., but the motor must never be allowed to operate
with open circuit voltage for prolonged periods of
time.
Options
1. Remote Contactor Control Option — This option
is externally located and connects to the feeder by
means of a control cable which is added to the
feeder. When this option is installed, a relay is
added to the feeder and a 24-V AC gas valve option
is available.
The remote box requires 115-V AC input and in
turn provides 24 V AC to the feeder as well as a
contactor control relay closure to the power source.
The 24 V AC is also used to allow for inching of the
wire feed motor.
2. A voltmeter kit as well as an inches per minute
kit are available for this unit.
3. A remote arc voltage/current control is also
available which allows the user to adjust the power
source at the feeder.
Terminal strip TB1 is used to connect various
options to the feeder.
Maintenance
Switch S1 is used to turn the power into the feeder
on or off.
Cleaning of the Unit
Resistor R1 is the control potentiometer for the unit
which varies the output speed.
The motor control circuit on this feeder is a DC to
DC converter circuit. It uses the power supply output
Periodically remove a side panel of the cabinet,
and blow out the interior with clean, dry, compressed air of not more than 25 psi (172 kPa)
pressure. Do not strike any of the components with
the air hose nozzle.

DESCRIPTION, INSTALLATION, OPERATION AND MAINTENANCE
Description
Installation
The four-roll feedhead assembly consists of four
idler gear/feed rolls (item 2, Figure 1) for various
types and sizes of wire. See Feed Roll Kit (375980),
wire input guide (item 1), center guide (item 7),
output guide (item 5), feedhead plate (item 4) and
pressure arm assembly (item 6). The drive motor is
115 volt DC, controlled by solid-state or variac
speed control. See the data on the particular model
which is found in the manual of which this TIP is a
part.
Wire sizes from 0.030-inch (0.76 mm) diameter to
1/8 inch (3.18 mm) may be fed with selection of
proper feed rolls. See Feed Roll Kit (Drawing
375980-X, included in this manual) for feed roll
configuration and proper feed rolls for given sizes
and types of wire.
The Solenoid (Gas Control) Valve (optional) is
located on the back side of the Feedhead Plate. A
fitting for gas supply extends through the back panel
of the Control Box.
The feedhead assembly becomes a part of the
modular assembly which includes a control box
assembly, and a wire support assembly which may
be mounted on a common baseplate, or remotely
mounted, as on a boom unit.
Location — For best operating characteristics and
longest unit life, take care in selecting an installation
site. Avoid locations exposed to dust, high ambient
temperature, or corrosive fumes.
Connections — The electrical connections for the
wire feeder are made both at the feedhead and
control box. The feedhead connection is made from
the power supply terminal to the feedhead as with
standard feeders. However, the feeder motor and
controls use the feedhead potential to supply operating power for the feeder. Be sure the cable connection to the feedhead is tight. A loose cable will
cause the feeder to malfunction.
Installation of Welding Wire Spool — See I-169 for
details.
Adjustment of Spool Tension — Adjust the tension
on the Wire Spool so that the wire will feed freely
into the feedhead (feed rolls), but will not “coast”
when wire feeding stops. Tighten or loosen the Hub
Tension Screw accordingly.
Threading Wire Into Feedhead — Refer to Figure
2.
CAUTION: Use care when handling the
spooled wire as it tends to unravel when
loosened from the spool. Grasp the end
of the wire firmly; do not let it get away!
Make sure the end of the wire is free of
burrs, and that it is straight.
1. Loosen the Pressure Arm Knobs, and raise the
Pressure Arm UP as shown in Figure 2.
2. Place the end of the wire into the Input Guide,
feeding it through the guide and over the feed roll
grooves.

If a TWECO #5 Backend Gun and Cable is to be
installed, the Gun Sleeve must be removed, the Gas
Inlet must be removed and replaced with another
one. See “B” on Figure 3. The Gas Inlet comes in a
kit (375999). To install the Gun and Cable, proceed
as follows:
1. Remove the Gun Receptacle Knob.
2. Remove the two retaining screws which secure
the Gas Inlet into the Feedhead Plate. This allows
the Gas Inlet to pull straight out.
NOTE: If the Gun Sleeve does not come
out easily, insert a screwdriver into the
slot (see Figure 3) and gently, but firmly,
pry the sleeve out.
5. Slide the new Gas Inlet (with Gas Tube installed) into place, making sure that the wide
groove, toward feed rolls, goes in first.
6. Replace the Retaining Screws to secure the
Gas Inlet into place.
NOTE: When the TWECO #5 Backend
Gun and Cable is installed, it may be necessary to change the Output Guide, depending upon new wire size. See
instructions for changing Output Guide in

Operation
The operation of this feedhead is a function of the
wire feeder assembly of which it becomes a part.
See the Wire Feeder Manual for the 2000 Series for
details which affect this operation.
Maintenance
Cleaning — Periodically blow off the feedhead
assembly with clean, dry, compressed air of not
more than 25 psi (172 kPa) pressure. Use care to
not strike component parts of the feedhead with the
air hose nozzle.
Figure 5
Input Guides
1. Loosen the Input Guide Retaining Screw and
pull the Input Guide Spring (Item 1, Figure 1) out of
the hex nylon Input Guide.
Page 4
Cleaning Feed Rolls and Gears — Using a small
wire brush, clean the grooves on the feed rolls and
gear teeth frequently. To clean the wire groove,
loosen the Pressure Arm Knob and raise the Pressure Arm. Remove the wire from the feed rolls.
Clean the gear teeth and check the screws which
hold the feed rolls on the gears.
Feedhead Maintenance — The only point of maintenance in the feedhead assembly is the motor
brushes. To inspect and/or change the brushes, the
feedhead assembly must be removed from the ConDecember 1, 1997 Revised
TIP-219
trol Box (in the 2000 Series composite assembly).
See Figure 6 and instructions for removing feedhead and motor from Control Box.
NOTE: There are two possibilities for
wire feed motors, depending upon which
manufacturer’s stock was used for the
particular assembly. The removal from
the Control Box is the same for both motors, but the procedure for changing
brushes is different.
1. Remove six screws from the top and side of the
Control Box which holds the Control Box Cover in
place. Loosen the screws (2) at the bottom of the
Cover, to allow the Cover to slip up off from the
screws in the slots provided.
2. Disconnect the power supply wire from the gun
receptacle. Remove the four screws and lockwashers which secure the Feedhead Mounting Plate to
the side of the Control Box. This will allow the
Feedhead assembly (including the motor) to pull
straight out of the Control Box, to a position (see
Figure 6) where the motor brushes may be serviced.
3. The Bodine gear motors are equipped with a
vent for the gearbox. The vent hole is plugged and
does not have to be removed for operation.
Bodine Motor Brush Inspection and Installation —
See Figure 7 — The brushes should be inspected
every 300 hours of operation. When brushes are
worn to about 3/8 inch (9.5 mm) in length, new
brushes should be installed. (Refer to Parts List for
brush part numbers.) See Figure 7 for following
procedure.
CAUTION: Neglect in brush maintenance may cause damage to commutator in the motor if allowed to wear away
completely.
1. See Step 1 on Figure 7. Lift and remove the
Brush Cap by prying the Rivet out of the hole in the
End Shield. This will reveal the brush assembly in
place as in Step 2.
2. Using long-nosed pliers, grasp the Spring Retaining Bracket. Slightly push the Retaining Spring
down and toward the brush. When the Bracket
unhooks from the Brush Box, lift the Retainer/Spring
out.
3. Using long-nosed pliers, grasp the connector on
one end of the brush pigtail and pull it straight up.
Disconnect it from the clip on the side of the Brush
Box. The Brush may be removed at this time.
Figure 6

NOTE: Blow dirt and foreign matter out of
the Brush Box with compressed air of not
more than 25 psi (172 kPa) pressure.
NOTE: Observe the direction which the
spring bends in order to reinstall the
brush in the same position, for best fit to
the motor commutator.
4. Install new brushes if necessary. Reassemble
the unit in reverse order of the dismantling procedure.
2. Lift the Brush/Spring out of the Brush Box.
3. Inspect Brush, check dimensions, blow out the
Brush Box with compressed air (see NOTE above).

BASE ASSEMBLY NO. 375769-1 & -4
DESCRIPTION AND INSTALLATION INSTRUCTIONS
Description
The base is designed for use in assembling a
composite Series 2000 Wire Feeder. It is a component which makes it possible to bring together a
Control Box and Feedhead Assembly (which have
their own TIP Instruction Sheets), and a Wire Spool
Support Assembly.
Installation
The illustration below shows the mounting of the
Control Box, Feedhead Assembly, and the Wire
Spool Support Assembly.
1. To mount the Control Box Assembly, align holes
in the base with the grommets (in the Control Box
bottom panel), insert the self-tapping mounting
screws through the holes in the base, into the nylon
grommets.
2. Tighten the screws in place, which will expand
the nylon grommets in the holes in the Control Box
bottom.
NOTE: The Feedhead Assembly is secured to the Control Box, and does not
bolt directly to the base.
3. Align four holes in the bottom flange on the Wire
Spool Support with four holes in the base (as shown
in illustration) and insert four capscrews through the
holes in the base and stiffener (underneath the
base) and secure in place with the four hex nuts.

INSTRUCTION SHEET - Installation of
Wire “Reel” or “Spool” on the Support
The wire feeder will be shipped from the factory
with a wire spool kit 870058 and a wire reel/spool
support assembly 870060-X. An “optional” wire reel
kit 870059 is also available.
WARNING: Mount spool with
hub nut angled upward (see Figure 1). Hub nut may detach causing personal injury from falling
wire coil spool if improperly
mounted.
Figure 2
c. Install the spool tension spacer, compression
spring, spacer, and the hub tension screw.
d. Place a wire spool on the hub (13). Align the
positioning pin on the hub with the hole in the wire
spool so that the wire feeds from the bottom of the
coil. See Figure 3.
Figure 1
1. To install the Wire Reel/Spool Support Assembly (870060-X) onto the Baseplate:
a. Use the four 1/4-20 x 7/8" screws, the four
hex keps nuts, and the two flat washers to fasten
the support (1) to the wire feeder base.
Figure 3
2. To install the Wire Spool Kit (870058):
a. Mount the shaft (6) in the lower hole (if using
a 30-45 lb. spool) or in the upper hole (if using a 60
lb. spool) of the support (1). Make sure the 1/2-13
hex nut (2) is securely tightened on the shaft (6).
See Figure 2.
b. Mount the Wire Spool Hub (13) on the Shaft (6).
e. Install the wire spool hub nut (17) and tighten
until the spring ball plunger falls into the dimple on
the wire spool hub.
f. Adjust the compression spring tension by use
of the hub tension screw until the proper reel drag
is achieved.

I-169
Figure 4
3. To install the Wire Reel Kit (870059):
a. Mount the shaft (6) in the upper hole of the
support (1) to assure proper clearance for the wire
reel (7). See Figure 4.
b. Mount the wire reel (7) on the shaft (6).
c. Install the wire reel washer, the steel wire reel
washer, compression spring, “T” wire reel washer,
and the drag adjusting screw.

Figure 5
d. Loosen the wing nuts holding the movable
arms. Rotate the arms inward towards the center of
the reel (7). Place the coiled wire on the reel so the
wire feeds from the bottom of the coil to the wire
feeder. See Figure 5.
e. Reposition the movable arms outward and
tighten the wing nuts.
f. Tighten the drag adjusting screw until the
desired reel drag is achieved.
