HydroStar® Blends

 

 

 

Praxair HydroStar gases are a family of hydrogen-enhanced blends available in a variety of precision formulations for top-quality welding and cutting. Each gas blend is designed to meet the demands of your specific Gas Tungsten Arc Welding (GTAW or TIG), Gas Metal Arc Welding (GMAW or MIG/MAG) and plasma welding, gouging or cutting applications. See Brochure.

 

Argon-Hydrogen Mixtures

 

Argon-Carbon Dioxide-Hydrogen Mixtures

The Praxair HydroStar® shielding gas blends are primarily used for joining austenitic stainless steels utilizing the Gas Tungsten Arc Welding (GTAW or TIG) process. Hydrogen increases heat input to the base materials while providing a reducing atmosphere to enhance weld cleanliness. Significant advantages in travel speed over pure argon can be attained.

 

The Praxair HydroStar® PBSS gas blend is designed for the all-position welding of austenitic stainless steels using pulsed spray transfer. Optimum weld quality and cleanliness is achieved at high levels of productivity. Conventional spray transfer can also be used.

Top Quality And Consistency

Every Praxair HydroStar shielding gas blend you order is mixed consistently at every level. Praxair’s patented Starblend™ mixing system technology is specially designed for maintaining mixture integrity with argon-based blends containing carbon dioxide. Complete evacuation and purging of empty cylinders is required before filling using our patented eductor tube blending system. There’s no residual gas waste from stratification so you can use all the gas you’ve ordered every time — while also reducing your costs.
