Abstract

A consumable cartridge for a plasma arc torch is provided. The consumable cartridge includes an outer component defining a substantially hollow body, an inner component disposed substantially within the hollow body of the outer component, and a hollow region between the rear portion of the inner component and the outer component. The inner component includes a forward portion configured to axially secure and rotatatably engage the outer component to the inner component and a rear portion substantially suspended within the hollow body of the outer component. The rear portion is axially secured and rotatably engaged with the outer component via the forward portion. The hollow region is configured to receive a torch head to enable mating between the rear portion of the inner component and a cathode of the torch head.
