Abstract
A method for conducting gas in a gas-cooled plasma torch wherein the plasma torch has a plasma torch body which holds an electrode with an open end and a closed end. A cavity extends from the open end in the direction of the closed end, and which, with a spacing in an axial direction, holds a nozzle by means of a nozzle holder. The nozzle has a central opening with an upstream inlet end, into which the electrode projects, and with an outlet end with a nozzle bore and is surrounded by a nozzle cap and/or a nozzle protection cap. The plasma torch body has an opening for a gas feeder, which opening is fluidically connected to a cooling tube which projects into the open end of the electrode.
