See your Owner's Manual for complete safety precautions and procedures

See your Owner's Manual for complete safety, set-up and installation procedures. The following diagram and instructions show a typical TIG welding system and connections.

TIG welders can be used to weld steel, stainless steel, chromoly, aluminum, nickel alloys, magnesium, copper, brass, bronze, and even gold. TIG is a useful welding process for welding wagons, bike frames, lawn mowers, door handles, fenders, and more.

In TIG welding, a tungsten electrode heats the metal you are welding and gas (most commonly Argon) protects the weld puddle from airborne contaminants. TIG welding produces clean, precise welds on any metal.

Always read and follow the safety precautions and operational instructions in your owner's manual.

The best feeding of wire for aluminum is done with a spool gun. If you can't use a spool gun, use the shortest gun possible and keep the gun as straight as possible. Use argon only for shielding gas. Only use a push gun technique when welding aluminum.

Always read and follow the safety precautions and operational instructions in your owner's manual.

The combination of cut quality, productivity, operating cost, and versatility make plasma today’s most popular industrial cutting process.
