Stargon SS Welding Blend for Stainless Steel
™

Avoid Rising Helium Costs, While Improving Quality In Stainless Steel Welding
The world’s supply of helium is fi nite and with a growing demand, prices continue to climb. When welding stainless steel,
helium’s thermal conductive properties help to produce fi ne and fl at welds. Stargon SS blend is able to duplicate the arc
characteristics of helium welding blends with its unique composition, while offering signifi cant cost savings.
Praxair’s Stargon SS gas blend is a carefully controlled blend of argon, carbon dioxide and nitrogen. It is designed for
joining a variety of thick or thin stainless steels in all positions, and performs well in short circuit, spray and pulsed spray
welding modes.

Exceptional Performance on Thin Materials Stargon SS Blend Performance

Stargon SS blend allows for lower welding voltages,  Contains no helium and duplicates helium blend
compared to helium blends. This means less heat input performance
during welding, resulting in less metal distortion. Lower heat  Excellent arc stability and penetration
input using Stargon SS blend also decreases sensitization  Good weld appearance and color matching
of the chrome in the weld, thus improving corrosion  Controlled CO2 levels for reduced carbon content
resistance in the weldment. This makes Stargon SS blend and improved corrosion
an ideal blend for sheet metal and thin-gauge applications.  Lower arc voltage on thin materials reducing heat
input and distortion
