The Linde Stargon® CS shielding gas blend, a precise mixture of argon, carbon dioxide and oxygen, is a universal shielding gas for joining all types of carbon steel. Linde 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.
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. Linde's 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.
