MIG Welding

MIG Welding, also known as Gas Metal Arc Welding (GMAW), is a process developed in the 1940`s that is considered semi-automatic and requires electricity to produce heat, an electrode to fill the joint and a shielding gas to protect the weld from the air.  A MIG welder utilizes a constant DC current while wire and gas are fed continuously through the welding gun and leads as the gun`s trigger is depressed.  It is most commonly used in fabrication environments where production needs are high.
