Argon Carbon Dioxide blends are versatile mixtures for welding carbon, low-alloy and some stainless steels. Increasing the CO2 content will increase weld penetration and bead wetting characteristics. At higher current levels and CO2 content, increased spatter may result.

In short-circuiting yields good weld shape and color and increases welding speed. For spray and pulsed spray transfer it is nearly equivalent to other trimixes. When joining stainless to carbon steels in presence of nitrogen, care has to be taken to ensure the proper weld microstructure.
