Electrically isolated gas cups for plasma transferred arc welding torches, plasma transferred arc welding torches including such gas cups, and related methods are disclosed. In one embodiment a gas cup includes a dielectric portion sized and configured to couple with a torch body and electrically isolate the gas cup from the torch body. In additional embodiments, a plasma transferred arc welding torch includes an anode, a cathode, a torch body coupled to the anode and the electrode, and a gas cup at least partially surrounding the anode and electrically isolated from the torch body. In further embodiments, a method of coupling a gas cup to a plasma transferred arc welding torch includes coupling a dielectric structure to a gas cup and coupling the dielectric structure to a torch body to electrically isolate the gas cup from the torch body. |
