Flux-Cored Arc Welding - (FCAW). Flux-cored Arc Welding is a welding process similar to GMAW, in that it uses a continuously fed electrode, but uses a tubular wire filled with flux instead of a solid wire. There are two types of flux-cored wire, self-shielded and dual shield.
TIG Welding (GTAW) is a process that uses the a non-consumable tungsten electrode to produce a weld with or without a filler material. The equipment is significantly different than MIG equipment and somewhat different than what is used for stick welding. That said, a welding machine with the right accessories can be fitted for TIG welding.
