Argon-Carbon Dioxide-Oxygen Mixtures -- Stargon® CS Blend
The Stargon® CS shielding gas blend, a precise mixture of argon, carbon dioxide and oxygen, is a universal shielding gas for joining all typesof carbon steel. Stargon® CS can be used in the Gas Metal Arc Welding (GMAW) process with all modes of metal-transfer (spray, pulsed spray, short-circuiting). Stargon CS produces good arc characteristics and excellent weld mechanical properties.
Principal Applications
The Stargon® CS is widely used on carbon steel plate and pipe for the fabrication of cranes, earth moving and farm equipment, auto-body repair, sheet metal, pressure vessels, office furniture, and automotive components.
Stargon® CS Gas Blend
Mixtures containing these three components are versatile, due to their ability to operate using short-circuiting, globular, spray, pulsed, and high-density transfer modes. Several ternary compositions are available and their application depends on the desired metal transfer mode.
The advantage of this blend is its ability to shield carbon steel and low-alloy steel of all thicknesses using any metal transfer mode applicable. Stargon® CS produces good welding characteristics and mechanical properties on carbon low-alloy steels and some stainless steels. On thin gauge base metals, the oxygen constituent assists arc stability at very low current levels (30 to 60 amps) permitting the arc to be kept short and controllable. This helps minimize excessive melt-through and distortion by lowering the total heat input into the weld zone. Stargon® is generally used for spray arc welding, providing high deposition rates and often higher travel speeds than carbon dioxide.
