Parag Weld MIG 400 Pro
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-circuting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages & limitations.
The Process became highly used in industry. 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 shielding gas, instead employing a hollow electrode wire that is filled with on the inside.
