This equipment or any of its parts should not be altered without the prior written approval of
the manufacturer. The user of this equipment shall have the sole responsibility for any
malfunction which results from improper use, faulty maintenance, damage, improper repair or
alteration by anyone other than the manufacturer or a service facility designated by the
manufacturer.
WARNING!
These Safety Precautions are for your protection. They summarise precautionary
information from the references listed in the Additional Safety Information section.
Before performing any installation or operating procedures, be sure to read and
follow the safety precautions listed below as well as all other manuals, material
safety data sheets, labels, etc. Failure to observe the Safety Precautions could
result in injury or death.
PROTECT YOURSELF AND OTHERS
Some welding, cutting and gouging processes are noisy and require
hearing protection. The arc, like the sun, emits ultraviolet (UV) and
other radiation and can injure the skin and eyes. Hot metal can cause
burns. Training in the proper use of the processes and equipment is
essential to prevent accidents. Therefore:
1. Always wear safety glasses with side shields in any work area, even if welding helmets,
face shields and goggles are also required.
2. Use a face shield fitted with the correct filter and cover plates to protect your eyes, face,
neck and ears from sparks and rays of the arc when operating or observing operations.
Warn bystanders not to look at the arc and not to expose themselves to the rays of the
electric-arc or hot metal.

1 SAFETY PRECAUTIONS
3. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt, cuffless trousers,
high-topped shoes and a welding helmet or cap for protection, to protect against arc rays
and hot sparks or hot metal. A flameproof apron may also be desirable as protection
against radiated heat and sparks.
4. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves and
collars should be kept buttoned and open pockets eliminated from the front of the
clothing.
5. Protect other personnel from arc rays and hot sparks using a suitable nonflammable
partition or curtains.
6. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be
hot and can fly for long distances. Bystanders should also wear goggles over safety
glasses.
FIRES AND EXPLOSIONS
The heat from flames and arcs can start fires. Hot slag or sparks can
also cause fires and explosions. Therefore:
1. Remove all combustible materials well away from the work area or cover the materials
with a protective nonflammable covering. Combustible materials include wood, cloth,
sawdust, liquid and gas fuels, solvents, paints and coating paper, etc.
2. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings and
cause a hidden smoldering fire or fires on the floor below. Make certain that such
openings are protected from hot sparks and metal.
3. Do not weld, cut or perform other hot work until the workpiece has been completely
cleaned, to ensure there are no substances on the workpiece which might produce
flammable or toxic vapors. Do not perform hot work on closed containers. They may
explode.
4. Have fire extinguishing equipment handy for instant use, such as a garden hose, water
pail, sand bucket, or portable fire extinguisher. Be sure you are trained in its use.
5. Do not use equipment beyond its ratings. For example, overloaded welding cable can
overheat and create a fire hazard.
6. After completing work, inspect the work area to make sure there are no hot sparks or hot
metal that could cause a fire later. Use fire watchers when necessary.
7. For additional information refer to NFPA Standard 51B, "“Fire Prevention in Use of
Cutting and Welding Processes", available from the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.
ELECTRICAL SHOCK
Contact between live electrical parts and earth can cause severe injury
or death. DO NOT use AC welding current in damp areas, if movement
is confined, or if there is danger of falling. Therefore:
1. Be sure the power source frame (chassis) is connected to the earth system of the input
power.
2. Connect the workpiece to a good electrical earth.
3. Connect the work cable to the workpiece. A poor or missing connection can expose you
or others to a fatal shock.
4. Use well-maintained equipment. Replace worn or damaged cables.
5. Keep everything dry, including clothing, work area, cables, torch/electrode holder and
power source.

1 SAFETY PRECAUTIONS
6. Make sure that all parts of your body are insulated from the workpiece and from earth.
7. Do not stand directly on metal or the ground while working in tight quarters or a damp
area; stand on dry boards or an insulating platform and wear rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the power.
9. Turn off the power, before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 (listed on next page) for specific earthing
recommendations. Do not mistake the work lead for a earth cable.
ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric current flowing through any conductor
causes localised Electric and Magnetic Fields (EMF). Welding and
cutting current creates EMF around welding cables and welding
machines. Therefore:
1. Welders with pacemakers fitted should consult their doctor before welding. EMF may
interfere with some pacemakers.
2. Exposure to EMF may have other health effects which are unknown.
3. Welders should use the following procedures to minimise exposure to EMF:
a) Route the electrode and work cables together. Secure them with tape when possible.
b) Never coil the torch or work cable around your body.
c) Do not place your body between the torch and work cables. Route cables on the
same side of your body.
d) Connect the work cable to the workpiece as close as possible to the area being
welded.
e) Keep the welding power source and cables as far away from your body as possible.
FUMES AND GASES
Fumes and gases, can cause discomfort or harm, particularly in
confined spaces. Do not breathe fumes and gases. Shielding gases
can cause asphyxiation. Therefore:
1. Always provide adequate ventilation in the work area by natural or mechanical means.
Do not weld, cut or gouge on materials such as galvanised steel, stainless steel, copper,
zinc, lead beryllium or cadmium unless positive mechanical ventilation is provided. Do
not breathe in the fumes from these materials.
2. Do not operate near degreasing and spraying operations. The heat or arc can react with
chlorinated hydrocarbon vapours to form phosgene, a highly toxic gas and other irritant
gases.
3. If you develop momentary eye, nose or throat irritation while operating, this is an
indication that the ventilation is not adequate. Stop work and take the necessary steps to
improve ventilation in the work area. Do not continue to operate if physical discomfort
persists.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for specific ventilation
recommendations.
5. WARNING: This product when used for welding or cutting, produces fumes or gases that
contain chemicals known to the State of California to cause birth defects and in some
cases cancer (California Health & Safety Code §25249.5 et seq.)

1 SAFETY PRECAUTIONS
CYLINDER HANDLING
Cylinders, if mishandled, can rupture and violently release gas.
Sudden rupture of cylinder valve or relief device can injure or kill.
Therefore:
1. Use the proper gas for the process and use the proper pressure reducing regulator
designed to operate from the compressed gas cylinder. Do not use adaptors. Maintain
hoses and fittings in good condition. Follow the manufacturer's operating instructions for
mounting a regulator to a compressed gas cylinder.
2. Always secure cylinders in an upright position, by chain or strap, to suitable hand trucks,
undercarriages, benches, wall, post or racks. Never secure cylinders to work tables or
fixtures where they may become part of an electrical circuit.
3. When not in use, keep cylinder valves closed. Have valve protection cap in place if
regulator is not connected. Secure and move cylinders by using suitable hand trucks.
4. Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.
5. For additional information, refer to CGA Standard P-1, "Precautions for Safe Handling of
Compressed Gases in Cylinders", which is available from Compressed Gas Association,
1235 Jefferson Davis Highway, Arlington, VA 22202.
WARNING!
EQUIPMENT MAINTENANCE
Faulty or improperly maintained equipment can cause injury or death.
Therefore:
1. Always have qualified personnel perform the installation, troubleshooting and
maintenance work. Do not perform any electrical work unless you are
qualified to perform such work.
2. Before performing any maintenance work inside a power source, disconnect
the power source from the incoming electrical power.
3. Maintain cables, earthing wire, connections, power cord and power supply in
safe working order. Do not operate any equipment in faulty condition.
4. Do not abuse any equipment or accessories. Keep equipment away from
heat sources such as furnaces, wet conditions such as water puddles, oil or

Wire feed speed (Arc voltage control)
The wire feed speed is controlled by the knob for wire feed speed on the front of the wire
feeder.
When the wire feeder is connected to a constant voltage (CV) type of power source, the knob
for wire feed speed controls the welding current. Turning the knob clockwise increases the
welding current; turning it counterclockwise decreases the welding current.
When the wire feeder is connected to a constant current (CC) type of power source, the knob
for wire feed speed controls the arc voltage. Turning the knob clockwise decreases the arc
voltage; turning it counterclockwise increases the arc voltage. The actual wire feed speed for
any given setting varies with the arc voltage. Increasing the arc voltage causes an increase
in the wire feed speed.
When the CV/CC switch inside the MobileFeed is set to "CV," the “Preset” wire feed speed
will be shown on the display. The wire speed will not vary with changes in the arc voltage.

5 OPERATION
When the CV/CC switch is set to “CC”, the wire feed speed and voltage will be shown on the
display. The wire speed shown is the speed that will result from the displayed voltage.
Adjusting the knob for voltage affects the wire feed speed. For example, if the display shows
300 in/min and 20 V, an adjustment of the voltage to 24 V will result in an increase to
approximately 365 in/min. A change in arc voltage of 4 V will result in a change in wire speed
of 65 in/min. For a step-by-step guide to setting wire speed and voltage, see the section
“Setting a Welding Procedure.”
Voltage
In CC mode, the knob for setting the voltage is used to adjust the voltage, which in turn
affects the wire feed speed. See the "Wire feed speed" description above.
The knob for setting the voltage can also be used to set the power source output voltage
when the MobileFeed is set to CV with the remote voltage control option and a Warrior power
source is being used. The power source voltage is then read on the MobileFeed display for
wire feed speed and voltage.
Display for wire feed speed and voltage
The digital display shows the wire feed speed (in/min or m/min) and voltage. It also enables
the welder to preset wire feed speed and power source voltage.
Trigger lock switch
The trigger lock function is a variation of 4-stroke operation. If the trigger lock function is
turned on, the torch trigger can be released once the arc is established, the power
source/feeder will continue to weld until the trigger is pressed and released again, or the arc
established signal is lost by manually breaking the arc. The trigger will not be locked unless
the arc is established before the trigger is released.
Power switch
The power switch (0/I) on the front of the wire feeder starts the wire feeder when the feeder
is connected to the power source and the workpiece. The power source must be turned on
with the contactor closed.

Circuit breaker, 5 A
4.
CC/CV switch
Circuit breaker, 5 A
This resettable 5-amp circuit breaker, in series with motor armature, protects the control
board from damage if the motor is stalled.
Jog/Purge switch
JOG is used when you need to feed wire without welding voltage being applied. The wire is
fed at the set speed for as long as the switch is pushed.
PURGE is used when measuring the gas flow or to flush any air or moisture from the gas
hoses before welding starts. The gas flows as long as the switch is pushed. There is no need
for welding voltage or wire feed start.
If wire has been threaded through the gun and contact tip, simply operate the jog button or
cut off wire, as required, so that the wire extends about 1/2” beyond the end of the gun
nozzle.
CC/CV switch
The CC/CV switch is used to set CC or CV mode. CC mode is used for constant current
power sources. CV mode is used for constant voltage power sources. The selected mode
also affects the functions of the wire feeder as shown below:

Operating procedures
5.3.1
Operating safety precautions
Comply with all ventilation, fire, and other safety requirements for arc welding as established
in the section "SAFETY PRECAUTIONS."
1. Because of the radiant energy of the welding arc and the possibility of drawing an arc
before the helmet is lowered over the face, the operator should wear flash goggles with
filter lenses under his helmet. The helmet filter plate should be shade number 11
(nonferrous) or 12 (ferrous). All those viewing the arc should use helmets with filter
plates, as well as flash goggles. Nearby personnel should wear flash goggles.
2. The radiant energy of the arc can decompose chlorinated solvent vapors, such as
trichloroethane and perchlorethylene, to form phosgene, even when these vapors are
present in low concentrations. DO NOT weld where chlorinated solvents are present in
atmospheres in or around the arc.
3. DO NOT touch the electrode, contact tip, or metal parts when power is ON: all are
electrically energized (HOT) and can cause a possibly fatal shock. DO NOT allow
electrode to touch grounded metal. It will create an arc flash that can injure eyes. It may
also start a fire or cause other damage.

5 OPERATION
4. When working in a confined space, be sure it is safe to enter. The confined space should
be tested for adequate oxygen (at least 19%) with an approved oxygen measuring
instrument. The confined space should not contain toxic concentrations of fumes or
gases. If this cannot be determined, the operator should wear an approved air-supplied
breathing apparatus. Avoid gas leaks in a confined space, as the leaked gas can
dangerously reduce oxygen concentration in the breathing air. DO NOT bring gas
cylinders into confined spaces. When leaving a confined space, shut OFF the gas supply
at the source to prevent gas from leaking into the space. Check the breathing
atmosphere in the confined space to be sure it is safe to reenter.
5. Never operate the equipment at currents greater than the rated ampere capacity.
Overheating will occur.
6. Never operate equipment in a damp or wet area without suitable insulation for protection
against shock. Keep hands, feet, and clothing dry at all times.
7. Whenever the equipment is left unattended, turn OFF all control power, power supply
switches, and gas supplies. Open the main line switch.
8. Wear dark substantial clothing to protect exposed skin from arc burn, sparks, and flying
hot metal.
9. Turn off welding power before adjusting or replacing electrodes.
WARNING!
When the power switch is ON and the torch trigger is pushed, the electrode wire
becomes electrically hot and the wire feed rolls are activated. Do not touch the
wire as it may cause a possibly fatal shock. Unless welding, do not allow the wire
to touch a grounded metal surface as it will cause an arc flash. Keep clear of feed
rolls and drive gears.
WARNING!
Prior to welding, it is imperative that the correct protective clothing (welding coat
and gloves) and eye protection (glasses and welding helmet) be put on. Failure to
comply may result in serious injury.
CAUTION!
Do not terminate the arc by removing the torch from the weld area. Release the
torch trigger to stop welding before removing the torch.
WARNING!
Failure to turn off the shield gas in a confined space may result in a buildup of
fumes, displacing oxygen.

Setting a welding procedure
Quick setup procedure
1. For a Constant Voltage (CV) Power Source: set the desired arc voltage on the power
source.
2. For a Constant Current (CC) Power Source: set the desired weld current on the power
source.
3. On the MobileFeed unit: Set the desired wire feed speed with the knob for the wire feed
speed and use the values shown by the display as a guide.
A feeder in CV mode will show the actual wire feed speed while welding.
A feeder in CC mode will show a wire feed speed that varies with changes in arc voltage.
When not welding, the display will show what the wire feed speed will be at the displayed
voltage.

5 OPERATION
NOTE!
It is NOT RECOMMENDED to use the CV switch setting when using a CC power
source. Extreme wire feed speed sensitivity exists that makes it difficult to set a
stable welding condition. The arc stability is very dependent on maintaining
constant "Tip To Work" (TTW) distance which is almost impossible to control
when welding manually. CV setting is only recommended for use with CV power
sources.
Typical welding voltages for 5000 Aluminum are between 21 and 25 volts, which
limits the wire feed speed of the MobileFeed, especially if trying to weld with 035”
diameter 5356 alloy. Welding with wire diameters ≤3/64” and/or below 22 arc
volts could cause problems with limited wire feed speed and the inability to
achieve a good welding condition.
NOTE!
On many CV power sources, the actual welding arc voltage is less than the
“Open Circuit Voltage” (OCV) set on the power source front panel. Therefore, an
extra 3 to 6 volts may be added to the power source front panel setting to achieve
the actual arc voltage needed or shown in the tables.
5.3.6
Shutdown
1. Release the torch trigger switch to break the arc.
2. When leaving the equipment unattended, always turn off and disconnect all power to the
equipment and turn off the shielding gas supply at the source.

MAINTENANCE
WARNING!
Make sure that the branch circuit or main disconnect switch is OFF or electrical
input circuit fuses are removed from the power source main supply before
attempting any inspection or work on the inside of the wire feeder. Placing the
power switch on the welding machine in the OFF position does not remove all
power from inside of the equipment.
WARNING!
Inspection, troubleshooting, and repair of this equipment should be undertaken
by a competent individual having at least general experience in the maintenance
and repair of semi-conductor electronic equipment. Maintenance or repair should
not be undertaken by anyone without such qualifications.
6.1
Inspection and service
Keep equipment in clean and safe operating condition, free of oil, grease, liquid and metallic
particles which can cause short-circuits.
Regularly check cylinder valves, regulators, hoses and gas connections for leaks with soap
solution.
Check for and tighten loose hardware including electrical connections. Loose power
connections overheat during welding.
Immediately replace all worn or damaged power cables and connectors. Check for frayed
and cracked insulation, particularly in areas where conductors enter equipment.
The electrode wire and all metal parts in contact with it are electrically energized while
welding. Inspect these parts periodically for defective insulation and other electrical hazards.
WARNING!
If uninsulated cable and parts are not replaced, an arc caused by a bared cable
or part touching a grounded surface may damage unprotected eyes or start a fire.
Body contact with a bared cable, connector or uncovered conductor can shock,
possibly fatally.
Keep power cables dry, free of oil and grease and protected at all times from damage by hot
metal and sparks.
Clean dirt and metal particles from drive roll groove weekly; replace roll if badly worn.
6.2
Wire feeder
When soft wire is fed, the drive rolls may pick up metal from the wire surface. Accumulation
on the rolls may score the wire with resulting unwanted friction and incorrect feeding.
Inspect the rolls regularly and clean them with a fine-wire power brush. Avoid roughening, or
removing the hardness of groove surfaces in grooved rolls. Any roughening may score the
wire, just as the accumulation being removed may do.
6.3
Solenoid valve replacement
If there is no gas flow through the wire feeder, the gas solenoid valve may be clogged or
electrically malfunctioning and it should be replaced. When replacing the gas solenoid valve,
the inlet (with the word IN) must face the rear of the unit.

6 MAINTENANCE
6.4
Troubleshooting
If the welding equipment does not work correctly, inspect as follows:
1. With all power controls in position on and other operating controls at required settings,
visually check all power cables and connections for evidence of overheating or sparking.
WARNING!
To avoid shock, do not touch the electrode wire or parts in contact with it, or
uninsulated cable or connections.
2. Check all gas hoses, connections, flowmeters and regulators for possible sources of
leakage, breakdown or intermittent failure.
3. Isolate trouble to one part of the welding installation: primary power supply, power
source, wire feeder or wire guide train (casing, drive rolls, liners and contact tip). If this
inspection indicates trouble in the wire feeder, refer to the wiring diagram.
WARNING!
Many troubleshooting situations require that the power remain on and that power
terminals in the equipment carry voltage. Exercise extreme caution when working
on “live” equipment. Avoid contact with electrical components, except when
testing with an appropriate instrument.
CAUTION!
Do not make any repairs to equipment unless you are fully qualified, as described
in the maintenance section.
