6 OPERATION
For GTAW welding, the welding power source must be supplemented with:
• a TIG torch with gas valve
• an argon gas cylinder
• an argon gas regulator
• tungsten electrode
Arc air gouging
For 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 the melted material is blown away.
For arc air gouging the power source must be supplemented with:
• arc air torches
• compressed air
• return cable with clamp

SMAW welding
SMAW welding may also be referred to as welding with coated electrodes. Striking the arc
melts the electrode, and its coating forms protective slag.
For SMAW welding, the power source must be supplemented with:
• welding cable with electrode holder
• return cable with clamp
GMAW and self-shielded cored wire welding
An arc melts a wire that is fed continuously. The weld pool is protected by shielding gas.
For GMAW and self-shielded core wire welding, the power source must be supplemented
with:
• wire feed unit
• welding torch
• connection cable between the power source and wire feed unit
• gas cylinder
• return cable with clamp
