Generally you will be using a pure argon shielding gas when you are MIG welding aluminum. Other welding techniques that are effective for aluminum include TIG tungsten inert gas welding and MIG metal inert gas welding. Pure argon can be used for both GMAW and GTAW welding and is the most popular of the shielding gases used for aluminum.
The output capacity of your welder determines the thickness you can weld.
