Abstract
A nozzle for a plasma arc torch is provided. The nozzle includes a substantially hollow, elongated nozzle body capable of receiving an electrode, the body defining a longitudinal axis, a distal end, and a proximal end. The nozzle also includes a swirl sleeve attachable to an interior surface of the nozzle body, the swirl sleeve configured to impart a swirling motion to a gas introduced to the nozzle. The nozzle additionally includes a nozzle tip connected to the proximal end of the nozzle body, a nozzle shield, and an insulator configured to connect the nozzle tip and the nozzle shield to electrically insulate the nozzle shield and the nozzle tip from one another while transferring thermal energy therebetween.
