Shieldpro 33 (formerly Supagas Supastainless 35) is a high performance gas for used for the welding of stainless steel and duplex

He / O2 / Ar

Shieldpro 33 has the addition of helium, which enables them to achieve higher performance in the areas of welding speed, penetration, profile, surface appearance, metallurgical benefits etc. This improves the two major areas of concern in a welding process - quality and economics.


  • Ideal for MIG welding of stainless steels and duplex 3mm and above
  • Good deposition rates and weld profile
  • Reduced spatter
  • Good edge wetting
