Argon Helium Mixtures

The Praxair HeliStar A1025 blend is widely used for its optimized short-circuiting transfer in stainless steel welding.

The Praxair HeliStar CS gas blend is specially formulated for the high deposition welding of carbon steel.

The Praxair HeliStar SS shielding gas blend is used to join stainless steel with all forms of metal transfer.

Praxair's HeliStar GV blend is superior to two part gas blends for welding coated steels because of the increased arc stability it provides. The addition of helium to this gas blend also makes higher travel speed possible in a number of applications.

The Praxair HeliStar argon/helium blends are used in a wide variety of Gas Tungsten Arc Welding (GTAW or TIG) applications where increased heat input to the base material is desirable while maintaining favorable arc starting and stability characteristics.
