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.

NOTE

Replace kinked liner or if the hole is dirty or worn. Make sure the end of the

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

of the gun. Then, loosen the conduit set screw in the rear connector plug.

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.
