Continuous feeding of combustion between the wire and the workpiece arc.
This method is the use of
arc welding as a heat source by the torch nozzle to spray the gas shielded arc. MIG arc welding is usually protective gases argon, helium, carbon dioxide gas or a mixture of these gases. When argon or helium as a shielding gas called metal inert gas shielded arc welding (MIG welding internationally called).
The main advantage of MIG arc welding can be welded at various locations. But also it has a welding speed, higher deposition rates of advantages.
