First Claim
1. A consumable cartridge for a plasma arc torch, the consumable cartridge comprising:
- an outer component defining a substantially hollow body;
an inner component disposed substantially within the hollow body of the outer component, the inner component comprising;
a forward portion configured to axially secure and rotatatably engage the outer component with respect to the forward portion of the inner component; and
a rear portion substantially suspended within and without being in direct physical contact with the hollow body of the outer component, the rear portion axially secured and rotatably engaged with respect to the outer component via the forward portion; and
a hollow region between the rear portion of the inner component and the outer component, the hollow region configured to receive a torch head to enable mating between the rear portion of the inner component and a cathode of the torch head.
