5 OPERATION
• an argon gas regulator
• tungsten electrode
Arc air gouging
For arc air gouging, a special electrode is used comprised of a carbon rod with a copper
casing.
An arc is formed between the carbon rod and the workpiece, which melts the material.
Compressed air is supplied, so the melted material is blown away.
For arc air gouging the power source must be supplemented with:
• arc air torches
• return cable with clamp
• air pressure

WARNING!
Use only compressed air. Use of combustible compressed gases can cause
explosions.

MMA welding
MMA welding may also be referred to as welding with coated electrodes. Striking the arc
melts the electrode, and its coating forms protective slag.
For MMA welding the power source shall be supplemented with:
• welding cable with electrode holder
• return cable with clamp
MIG/MAG and self-shielded cored wire welding
An arc melts a continuously supplied wire. The weld pool is protected by shielding gas.
For MIG/MAG and self-shielded core wire welding, the power source shall be supplemented
with:
• wire feed unit
• welding torch
• connection cable between power source and wire feed unit
• gas cylinder
• gas regulator (not needed for self-shielded core wire welding)
• return cable with clamp
