Shieldpro 31 (formerly Supagas Supastainless 62) is a high performance gas for used for the welding of stainless steel

He / CO2 / Ar

Shieldpro 31 has the addition of helium, which improves their performance in the areas of welding speed, penetration, profile, surface appearance, metallurgical benefits etc. This in turn improves the two major areas of concern in a welding process - quality and economics.


  • Ideal for MIG welding of stainless steels of all thickness
  • Good deposition rates, weld profile and smooth surface appearance
