Abstract
A plasma cutting and gouging torch has a torch body and a torch head that defines a longitudinal axis. A nozzle is aligned with the longitudinal axis and is secured to the torch head at the plasma discharge end for discharging plasma through the nozzle outlet and onto a workpiece. A handle is secured onto the head and extends outward from the torch head. A shield is secured to the torch head and extends substantially around the periphery of the torch head opposite the handle and extends along the surface of the handle confronting toward the nozzle. The shield extends in close, spaced relation to the torch head and handle to define a narrow, insulating air gap between the torch body and the shield. A flow of air may be introduced into the formed air gap to aid in cooling the torch body during cutting or gouging.
