identify the function of each kind of welding machine

1. Metal Inert Gas - On the material surface, it stabilizes the arc roots. Ensures that molten droplets from the wire are smoothly transferred to the weld pool.
2. Gas Metal Arc Welding - In this process, an arc is struck between the base metal and a continuously supplied consumable electrode, which provides filler metal for the weld
3. Tungsten Inert Gas - Is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.
