The BOC Stainshield range consists of a mix of argon, helium and carbon dioxide shielding gases for MIG welding of stainless steel and an argon-hydrogen mixture for TIG welding austenitic stainless steels.

The addition of helium to the MIG welding shielding gas allows more heat to be transferred into the weld than with argon alone. Carbon dioxide is added to improve the arc stability and droplet transfer characteristics, reducing spatter.

BOC Stainshield helps skilled welders to produce smooth, clean, defect-free welds in all grades of stainless steel.

There are three gases for MIG welding in the BOC Stainshield range: Stainshield Light, Stainshield Universal and Stainshield Heavy. By combining the properties of argon, carbon dioxide and helium, Stainshield mixtures are each tailored for welding a range of material thicknesses.
