Abstract

A nozzle for a plasma arc torch includes a body having a first end and a second end. The nozzle also includes a plasma exit orifice located at the first end of the body. A flange is located at the second end of the body. The flange is adapted to mate with a corresponding consumable. The flange is configured to selectively block at least one gas passage in the corresponding consumable to establish a gas flow relative to the nozzle body.
