5.7 Shielding gas
The choice of suitable shielding gas depends on the material. Typically mild steel is welded
with mixed gas (Ar + CO
2
) or 100% carbon dioxide (CO
2
). Stainless Steel can be welded
with mixed gas (Ar + CO
2
) or Trimix (He + Ar + CO
2
). Aluminum 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.
