Zusammenfassung:A nozzle for a gas-cooled plasma arc torch is provided. The nozzle includes a nozzle body formed from a first metal. The nozzle body comprises a proximal portion and a distal portion extending along a longitudinal axis. The distal portion of the nozzle body comprises a first bore. The nozzle also includes an arc transition component formed from a second metal. The arc transition component is coupled to the distal portion of the nozzle body and comprises a second bore configured to substantially align with the first bore when the arc transition component is coupled to the nozzle body. The second metal of the arc transition component comprises a noble metal and the second metal is different from the first metal.
