SAFETY AND OPERATING INSTRUCTIONS
89200005Safety Precautions
SECTION 2:
SAFETY PRECAUTIONS
WARNING
SERIOUS INJURY OR DEATH may result if welding and cutting equipment is
not properly installed, used, and maintained. Misuse of this equipment and other
unsafe practices can be hazardous. The operator, supervisor, and helper must read
and understand the following safety warnings and instructions before installing
or using any welding or cutting equipment, and be aware of the dangers of the
welding or cutting process. Training and proper supervision are important for a
safe work place. Keep these instructions for future use. Additional recommended
safety and operating information is referenced in each section.
WARNING
This product contains chemicals, including lead, or otherwise produces chemicals
known to the State of California to cause cancer, birth defects and other
reproductive harm. Wash hands after handling. (California Health & Safety Code
§ 25249.5 et seq.)
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH
Install and maintain equipment in accordance with the National Electrical Code
(NFPA 70) and local codes. Do not service or repair equipment with power on.
Do not operate equipment with protective insulators or covers removed. Service
or repair to equipment must be done by qualified and/or trained personnel
only.
Do not contact electrically live parts. Always wear dry welding gloves that are in good condition.
Aluminized, protective clothing can become part of the electrical path. Keep oxygen cylinders,
chains, wires, ropes, cranes, and hoists away from any part of the electrical path. All ground
connections must be checked periodically to determine if they are mechanically strong, and
electrically adequate for the required current. When engaged in AC welding/cutting under wet
conditions or where perspiration is a factor, the use of automatic controls for reducing the no
load voltage is recommended to reduce shock hazards. Accidental contact must be prevented
when using open circuit voltage exceeding 80 volts AC, or 100 volts DC by adequate insulation
or other means. When welding is to be suspended for any length of time, such as during lunch
or overnight, all electrode holders and electrodes should be removed from the electrode holder
and the power supply should be turned off to prevent accidental contact. Keep MIG guns,
electrode holders, Tig torches, Plasma torches, and electrodes away from moisture and water.
See safety and operating references 1, 2, and 8.
SAFETY AND OPERATING INSTRUCTIONS
2-389200005
SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH
Ventilation must be adequate to remove smoke, fumes, and gases during operation
to protect operators and others in the area. Vapors of chlorinated solvents can
form the toxic gas “Phosgene when exposed to ultraviolet radiation from an
electric arc. All solvents, degreasers, and potential sources of these vapors must
be removed from the operating area. Use air-supplied respirators if ventilation
is not adequate to remove all fumes and gases. Oxygen supports, and vigorously accelerates fire
and should never be used for ventilation.
See safety and operating references 1, 2, 3, and 4.
ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN
Welding and cutting processes produce extreme localized heat and strong
ultraviolet rays. Never attempt to weld/cut without a federally compliant welding
helmet with the proper lens. A number 12 to 14 shade filter lens provides the
best protection against arc radiation. When in a confined area, prevent the
reflected arc rays from entering around the helmet. Approved shielding curtains
and appropriate goggles should be used to provide protection to others in the surrounding area.
Skin should be protected from arc rays, heat, and molten metal. Always wear protective gloves
and clothing. All pockets should be closed and cuffs sewn shut. Leather aprons, sleeves, leggings,
etc. should be worn for out-of-position welding and cutting, or for heavy operations using large
electrodes. Hightop work shoes provide adequate protection from foot burns. For added protection,
use leather spats. Flammable hair preparations should not be used when welding/cutting. Wear
ear plugs to protect ears from sparks. Where work permits, the operator should be enclosed in
an individual booth painted with a low reflective material such as zinc oxide.
See safety and operating references 1, 2, and 3.
WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS
Combustibles reached by the arc, flame, flying sparks, hot slag, and heated
materials can cause fire and explosions. Remove combustibles from the work
area and/or provide a fire watch. Avoid oily or greasy clothing as a spark may
ignite them. Have a fire extinguisher nearby, and know how to use it. If welding/
cutting is to be done on a metal wall, partition, ceiling, or roof, precautions must
be taken to prevent ignition of nearby combustibles on the other side. Do not
weld/cut containers that have held combustibles. All hollow spaces, cavities, and containers
should be vented prior to welding/cutting to permit the escape of air or gases. Purging with inert
gas is recommended. Never use oxygen in a welding torch. Use only inert gases or inert gas
mixes as required by the process. Use of combustible compressed gases can cause explosions
resulting in personal injury or death. Arcing against any compressed gas cylinder can cause
cylinder damage or explosion. See safety and operating references 1, 2, 5, 7, and 8.
NOISE CAN DAMAGE HEARING
Noise from the air carbon-arc process can damage your hearing. Wear protective
hearing devices to ensure protection when noise levels exceed OHSA standards.
Adequate hearing protection devices must be worn by operators and surrounding
personnel to ensure personal protection against noise.
See safety and operating references 1, 2, and 6.

liner is smooth.
1. Lay the MIG Gun out on a table or floor in a straight line. Fully extend the gun and remove
all twists in the cable.
2. Remove the nozzle and the gas diffuser, then loosen the conduit set screw in the handle

6.03 INSTALLATION
1. Uncoil the conduit and lay it in a straight line. Remove any burrs or edges on the liner.
Insert the conduit into the rear connector plug. Push the conduit into the gun with short
strokes without kinking (bending) the liner. If the conduit hangs up, twist the conduit
counterclockwise or gently whip the cable while applying pressure to the conduit.
2. When the conduit is completely in the gun, tighten the rear conduit set screw.
3. Trim the conduit extending from the conductor tube to 1/2"(12,6 mm).
4. File the trimmed conduit end to remove burrs that could interfere with wire feeding or
catch on the diffuser.
5. Replace the diffuser and contact tip. Tighten securely, then replace the nozzle.
6. The MIG gun is now ready to be reinstalled on the feeder.
6.04 BRONZE JUMP LINER
Part No. AWC44-116 (Stock No. 1644-1085)
Using a jump liner improves arc starts and provides an improved current transfer between the
contact tip and aluminum wire. The jump liner can be used for wear issues found inside the
conductor tube area caused by the liner when using stainless steel wires.
6.05 CONNECTING WATER LINE TO TWECO WATERCOOLER
1. Attach the rear blue coolant inlet hose on the MIG gun to the pump connection labeled
“WATER OUT”.
2. Attach the rear red coolant outlet hose on the MIG gun to the sight glass connection
labeled “WATER IN”.
3. Use a minimum water supply of 3/4 gallons/minute (2.84 liters/minute) during
operation. If possible, install the water supply to run when the power source is turned
“on” to avoid damage to torch and/or cable assembly.
CAUTION
Operating a water-cooled torch and cable assembly without water or with restricted
flow will result in damage to the cable assembly.
NOTE
Do not exceed coolant temperature of 155ºF (60ºF).
4. Incorporating a flow switch on water-cooled assemblies is recommended to avoid
catastrophic failure and production loss. For best results, place the flow switch in
line with the water-cooled gun outlet hose. The circuit functions as an emergency
stop, normally-closed circuit. When water flows at .25 gallons/minute or more, the
circuit is closed.

SECTION 7:
TROUBLESHOOTING
Contact tips and nozzles should be cleaned frequently. Spatter buildup may cause bridging
between the nozzle and tip. This could cause electrical shorting between the nozzle and
workpiece as well as poor or improper gas flow.
Regularly inspect the conductor tube, handle, cablehose, and other parts of the MIG gun for
abrasion, cuts, or undue wear. Replace or repair any parts found deficient.
