During the welding, process metals are exposed to temperatures of upwards of 7000 Degrees. At these temperatures, most metals become liquid, which allows the formation of the weld. Argon is used to protect the molten pool of metal against elements in the Atmosphere including Oxygen, Nitrogen, and Hydrogen. These elements cause reactions with the liquid weld pool, such as porosity and increased weld spatter. Argon also plays an important role in maintaining Arc stability, which leads to increased weld penetration, better filler wire transfer, and better
