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

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
• return cable with clamp
