When you want to ensure precision high-quality welds in the most pressing environments, you want Praxair HeliStar helium-enhanced shielding gases. These helium-enhanced blends are available in a variety of precise formulations. That means there's a Praxair HeliStar gas blend to meet your specific Gas Metal Arc Welding (GMAW or MIG/MAG), Gas Tungsten Arc Welding (GTAW), Plasma Arc Welding (PAW) and Laser welding applications.

Argon-Helium Mixtures for Coated Steel Welding

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. The Praxair HeliStar A-75, A-50, and A-25 blends can also be used for Gas Metal Arc Welding (GMAW or MIG) of thick aluminum sections and for other non-ferrous materials where additional heat input to the base material enhances welding performance.

Principal Applications

Praxair HeliStar blends are used for TIG welding of light gauge steel, stainless steel, and aluminum applications such as bicycle frames, food service equipment and recreational boats. The heavier aluminum and copper section materials found in tanks and electrical equipment are joined using the MIG process and HeliStar gas mixtures.
