Shielding Gas

The choice of suitable shielding gas depends on the material. Typically mild steel is welded with mixed gas
(Ar + CO2) or 100% carbon dioxide (CO2). Stainless Steel can be welded with mixed gas (Ar + CO2) or Trimix
(He + Ar + CO2). Aluminium and silicon bronze use pure argon gas (Ar). In the sMIG mode (see section "sMIG
mode" in the CONTROL PANEL chapter) the optimal welding arc with the gas you use will be automatically set.

Volt Ampere Curves

The curves below show the maximum voltage and amperage output capabilities of the power source for three
common welding process settings. Other settings result in curves that fall between these curves.
