PROMIG500SMART - PRAXAIR MIG Welding Machine

Metal Inert Gas (MIG) welding is an arc welding process that uses a continuous solid wire electrode heated and fed into the weld pool from a welding gun.MIG welding is an arc welding process in which a continuous solid wire electrode is fed through a welding gun and into the weld pool, joining the two base materials together. A shielding gas is also sent through the welding gun and protects the weld pool from contamination. In fact, MIG stands for metal inert gas.MIG stands for Metal Inert Gas. Only inert gases or gas mixtures are used for the shielding gas when MIG welding. Typical inert gases used for MIG welding are argon and helium. These gases are usually used for MIG welding of aluminium and other non-ferrous metals.GMAW, also known as metal inert gas (MIG) welding, is a type of gas-shielded welding generally used in the manual mode but can be automated. The filler wire also is the electrode, and it is supplied in coils of solid bare wire.
