Argon (Ar) and carbon dioxide (CO2) are “pure” welding gases, meaning they can serve as solo shielding gases. They protect the weld area from atmospheric gases that could contaminate it and cause significant structural issues with the workpiece. Oxygen (O2) is an additive that enhances the properties of the other shielding gases.
Combining these three gases can provide superior results. Many welding professionals refer to this versatile mixture as a universal combination because it performs well with short-circuiting, globular transfer and spray transfer processes. The carbon dioxide deepens the penetration, while the oxygen promotes better transfer at a lower voltage.
