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
). Aluminium and silicon bronze use pure
argon gas (Ar). In the sMIG mode (see section "sMIG mode" in the USER INTERFACE
chapter), the optimal welding arc with the gas used will be automatically set.
