Abstract
A plasma arc torch includes a nozzle body, a nozzle extending from the nozzle body, and a shield cap. An outer retaining cap is attached to the plasma arc torch and secures the shield cap to the plasma arc torch. A sleeve is located radially outward from the outer retaining cap and is configured to receive a flow of pressurized gas. An insulator is located between the outer retaining cap and the sleeve. At least one of the sleeve and the insulator forms a gas flow channel configured to direct a gas flow from the sleeve to a distal portion of the outer retaining cap.
