Argon Gas Inert Gas. Shielding Gasses for Stainless Steel MIG Welding. THE MANUAL MIG WELD LABOR COSTS.
MIG welders use a variety of gases depending on the metal you are welding With mild steel youll use a mixture of CO2 and argon.
The gasses used are what shield the weld from the air that causes weld defects such as porisity. Basic shielding gas choices for Stainless are. For example 40 CF Argon 7525 CO2 costs roughly 150-170. But you gain penetration and speed.
