The primary difference between Plasma Arc Welding (PAW) and Tungsten Inert Gas (TIG) welding lies in the construction of the torch. In PAW, the torch design allows the plasma arc to be forced through a fine bore hole in the nozzle which focuses the arc, whereas in TIG welding, the arc is not as tightly focused.
