MIG (Metal Inert Gas) and MAG (Metal Active Gas) welding are commonly used when medium and high melting rates are required. Both techniques use a DC arc combustion between the workpiece and a wire electrode, which simultaneously functions as a power carrier and a source of metal-fill material.
GMAW (Gas Metal Arc Welding) is a welding or joining process of similar metals by using additional materials in the form of coiled wire and protective gas through a liquefaction process.

Benefits of using MIG Welding Machine :

1. The welding process is faster when compared to SMAW welding or MMA welding machines.
2. The fire released is more stable so that the welds obtained are also stronger and more durable.
