Mig Welding Inverter
Metal Inert Gas (MIG) welding or Metal Active Gas (MAG) welding, also known as Gas Metal Arc Welding (GMAW) is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage, DC power source is most commonly used with MIG MAG, but constant current systems, as well as AC, can be used. There are four primary methods of metal transfer in MIG MAG, called globular, short-circuiting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages and limitations.

Originally developed for welding and other non-ferrous materials in the 1940s, MIG MAG was soon applied to steels because it allowed for lower welding time compared to other welding processes. The cost of inert gas limited its use in steels until several years later, when the use of semi-inert gases such as carbon dioxide became common. Further developments during the 1950s and 1960s gave the process more versatility and as a result, it became a highly used industrial process. Today, MIG MAG is the most common industrial welding process. preferred for its versatility, speed and the relative ease of adapting the process to robotic automation. Unlike welding processes that do not employ a shielding gas, such as MMA it is rarely used outdoors or in other areas of air volatility. A related process, flux cored arc welding, often does not utilize a shielding gas, instead employing a hollow electrode wire that is filled with on the inside.
