HeliStar A1025 This blend is widely used for short-circuiting transfer welding of stainless steel in all welding positions. The carbon dioxide content is kept low to minimize carbon absorption and assure good corrosion resistance, especially in multi-pass welds. The argon and carbon dioxide additions provide good arc stability and depth of fusion. The high helium content provides significant heat input to overcome the sluggish nature of the stainless steel weld pool.

HeliStar CS This blend has been developed for spray and pulsed spray arc welding of both carbon and low-alloy steels. It can be used on all thicknesses in any position. This high-speed blend will produce higher quality welds over rust, oil and mill scale than conventional two-part mixtures. It produces good mechanical properties and weld puddle control.

HeliStar GV A specially formulated mixture of argon, helium and carbon dioxide, this blend is designed for joining a variety of coated steels. It reduces the spatter and porosity problems commonly associated with the welding of coated steels. Both galvanized and galvannealed materials can be successfully joined without the need for additional post-weld cleanup and rework.
