Shieldpro 27

Shieldpro 27 is a high performance gas for used for the welding of stainless steel, nickel and alloys

Ar /H2

Shieldpro mixtures have the addition of predominantly helium, hydrogen or nitrogen, which improves performance in the areas of welding speed, penetration, profile, surface appearance, metallurgical benefits etc. In turn, this improves the two major areas of concern in a welding process - quality and economics.


  • Ideal for TIG welding of stainless steel, nickel and alloys
  • Suitable for heavier sections of metal
  • Hydrogen addition gives higher welding speed due to hotter and more constricted arc
  • Austentic steels only
  • Increased deposition rates
  • Reduced oxides
  • Improved weld profile
