Ports - Within a mig gun you will discover smaller orifices (holes) that allow the flow of shielding fuel. The NOZZLE then directs the fuel out over the weld PUDDLE.

It works by using argon, helium or mixtures of inert gases for shielding the weld, and with minor to no smoke made; it is vitally very easy to see the WELD POOL. (Apart from Aluminum exactly where the puddle is quite hard to see.)
