Welding Aluminum With Mig Gas. Aluminum is non-ferrous metal and therefore you should only use 100 argon as the shielding gas. But what if you are out of gas and only have a few more welds to make before youre finished with your project.

MIG Welding Gas for Aluminum Welding. For most other MIG welding applications especially for steel 100 percent argon gas is. When welding mild steel you typically use whats called C25 gas 25 CO2 and 75 argon.

Because aluminum is a non-ferrous metal it requires a 100 percent argon shielding gas.

Welding of aluminum is typically done with Argon alone with one exception. That is the reason shielding gas is extremely important during the process of MIG welding as these inert gases provide a shield over the metal and prevent any kind of weld. Once the right equipment is set up its a pretty easy metal to weld. You should adjust the settings and use wires with low crack sensitivity to minimize porosity cracking and other defects.
