Remember that when MIG welding, the argon gas is the “flux” that protects the pool of liquid metal from contamination. If you’re welding outside, any cross-breeze can blow away the gas.

A MIG welder is capable of welding ferrous metals such as steel, aluminum, and stainless steel, depending on what type of shielding gas you use and the diameter and type of the weld wire.

Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the ...

In MIG welding, as long as the trigger is down ... welder can usually get by with 100 percent CO2 shielding gas. For a cleaner weld, use 75 percent CO2 and 25 percent argon.

Gas Metal Arc Welding (GMAW) is also known as metal inert gas (MIG) welding. GMAW is typically used for most types of metal and is faster than SMAW. This process involves the flow of an electric ...
