Shieldpro 20 (formerly Supagas Supa Pulse Mix) is a high performance gas for used for the welding of stainless steel

CO2 / Ar

Shieldpro 20 mixture has the addition of carbon dioxide, which improve performance in 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 of all thicknesses
  • Dip and spray transfer, minimal oxidation
  • Excellent for pulsed MAG
  • Good penetration and flat weld bead
  • Improved working environment
