Shieldpro 30

Shieldpro 30 (formerly Supagas Supastainless 20) is a high performance gas used for the welding of stainless steel and duplex

He / CO2 / Ar

Shieldpro 30 mixtures has the addition of helium, improving 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 and duplex 3mm and above
  • All round gas
  • Good deposition rates and weld profile
  • Increased penetration and fluidity of the weld pool
  • Higher weld speed compared to gases without helium
