ARC RAYS, MOLTEN MATERIAL, AND SPARKS CAN CAUSE EYE AND SKIN INJURY
Always wear approved eye, ear, and body protection. Remove any and all combustible material from the
work area. Never attempt to weld or cut without a proper head shield, with proper lens, that conform to
federal guidelines. A number 12 to 14 shade filter lens provides the best protection from arc radiation. A
cover plate protects your eyes from sparks.
Protect other nearby personnel from arc rays and sparks. Use approved shielding curtains and appropriate goggles.
Warn them not to watch the arc or expose themselves to arc rays, sparks, or molten material.
Always wear protective clothing and gloves which will not allow skin to become exposed to arc rays, heat, or molten
material. Wear ear plugs to protect ears from sparks. Flammable hair preparations should not be used when welding or
cutting.
If possible, welding should be done in a booth that has been painted with an ultraviolet absorbing material such as zinc
oxide and a low reflective finish such as lamp black, or shall be enclosed with noncombustible screens similarly painted.

WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS
Remove any and all combustible materials from the work area. If this is not possible, cover them to prevent
the welding sparks from starting a fire. Causes of fire and explosion are any combustibles reached by the
arc, flame, flying sparks, hot slag, or heated materials. Do not wear any gloves or clothing that has oil or a
fuel type material on it. Always have a properly working and OSHA approved Fire Extinguisher near and be sure everyone
has proper training in its use.
Do not weld, heat, or cut drums or containers that have held combustibles. All hollow spaces, cavities, and containers
should be vented prior to cutting, welding, or heating for they may explode. Make sure proper steps have been taken to
insure that venting procedures will not form flammable or toxic vapors from substances inside containers. Purging with inert
gas is recommended.
Use only inert gases or iner t gas mixes as required by the process. Special precautions should be used to prevent
hazardous situations when using compressed gas. Use of combustible compressed gases can cause explosions resulting in
personal injury or death. Never Use Oxygen for Cleaning or Purging.
Arcing against any compressed gas cylinder can cause cylinder damage or explosion. Read and follow the instructions on
compressed gas cylinders, Associated Equipment, and CEA Publication P-1, “Precautions for safe handling of compressed
gases in Cylinders” available from the Compressed Gas Association, 1235 Jefferson Davis Hwy, Arlington, Va. 22202.

DESCRIPTION
The Model AEC 200 Welding Gun is a complete hand held wire feeder with a 50 ft. *cable/hose assembly. The
cable/hose assembly is designed for operator comfort and extends from the top rear of the welding gun.
*If needed cable/hose assemblies of a longer length are available.
The Model AEC 200 Welding Gun will feed .030" through 1/16" diameter aluminum wires and .030" through .045"
diameter hard wires. *See selection chart for proper motor ratio for wire size selected. Wire drive motors are
interchangeable in the gun to make it readily adaptable for large or small welding applications. Each standard model comes
complete with all of the parts necessar y to weld with the wire diameter selected.
INSTALLATION
The Model AEC 200 Welding Gun should be connected to direct current (DC) reversed polarity (DC RP). The gun power
cable is connected to the positive (+) terminal on the welding power source or "GUN" terminal on the control box and the
negative (-) terminal of the welding power source is connected to the work piece through the work cable. If the welding
power source has a polarity switch, it should be set in the REVERSE polarity mode.
**IMPORTANT: When using power sources with high frequency, make certain high frequency is
turned OFF to avoid damage to the gun.
SAFETY
DISCONNECT ELECTRICAL POWER TO WELDING POWER SOURCE BEFORE ATTEMPTING TO MAKE ANY PRIMARY OR
SECONDARY CONNECTIONS. ELECTROCUTION MAY INJURE OR KILL.
