ABSTRACT:
A method and apparatus for indicating a temperature of a torch consumable is disclosed. The invention includes a shielding cup constructed to be attached to a torch having a coating which indicates a temperature of the shielding cup during a welding/cutting process. Preferably, the coating indicates to a user when the temperature of the torch is beyond a preferred operating range thereby preventing excessive wear of the consumables associated with overheating.
