Abstract
A plasma arc torch is provided for use in a plasma cutting system. The plasma arc torch includes a torch body for conducting electrical current. The torch body includes a torch tip configured to pass the electrical current to at least one consumable component connected to the tip. The plasma arc torch also includes at least one antenna positioned relative to the torch tip. The antenna is used to wirelessly detect the presence of the at least one consumable component. The plasma arc torch further includes a detection circuit configured to permit passing of the electrical current from the torch tip to the at least one consumable component based on at least the wireless detection.
