A MIG welding machine is a versatile arc welding process that utilizes a continuously fed consumable solid wire electrode. This wire acts as both the electrode and the filler metal for the weld. An inert gas (typically argon or helium) surrounds the electrode and molten metal, shielding them from airborne contaminants like oxygen and nitrogen that can weaken the weld.
