For applications requiring the unique properties of a single gas, Ozarc Gas provides a full line of high-purity options. These elemental gases serve as the foundation for many welding processes. Our selection includes argon for its stability during TIG and MIG welding of nonferrous metals such as aluminum and stainless steel. You will also find helium, which creates a hotter arc for enhanced weld penetration in thick materials and carbon dioxide (CO2), a cost-effective solution widely used in short-circuit MIG welding of carbon steel.
