Shieldpro 27

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

Ar / H2

Shieldpro 27 has the addition of hydrogen , 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
  • Austenitic steels only
  • Increased deposition rates
  • Reduced oxides
  • Improved weld profile
