Abstract
A consumable cartridge frame for a liquid-cooled plasma arc torch is provided. The consumable cartridge frame includes an insulator body configured to be disposed between a torch head and a cartridge tip. The consumable cartridge also includes a first cooling channel, disposed in the body, configured to conduct a first fluid flow received from the torch head to contact a component of the cartridge tip connected to the cartridge frame. The consumable cartridge further includes a first return channel, disposed in the body, configured to conduct at least a portion of the first fluid flow from the component to the torch head. The first cooling channel and the first return channel are non-concentric in relation to a central longitudinal axis of the body.
