Shieldpro 21

Shieldpro 21 is a high performance gas for used for the welding of stainless steel

O2 / Ar

Shieldpro mixtures have the addition of predominantly helium, hydrogen or nitrogen, which improve 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 steel up to 3mm
  • Dip transfer
  • Reduced penetration and smooth running
