A plug part for detachably connecting a torch neck of a gas-cooled welding torch to a socket part disposed on a hose package includes a cylindrical pipe element with a flange and with an axially extending channel for a welding wire and for a protective gas and includes a union nut which is rotatably disposed on the pipe element and which includes an inner thread for connection to a corresponding outer thread on the socket part. To produce an optimal connection between the torch neck and the hose package, a bevel is disposed on the flange of the pipe element of the plug part, and the end piece of the socket part has at least one axial slot.

A method and a device for generating a plasma jet under atmospheric pressure for the surface treatment of workpieces has a supply line for the plasma-capable medium, and an apparatus for electrically exciting the plasma-capable medium by an electric arc periodically ignited between a cathode and an anode constructed as a nozzle. To achieve a highly effective plasma jet even at relatively low temperatures of the plasma jet, a heating apparatus for preheating the plasma-capable medium is arranged upstream of the apparatus for electrically exciting the plasma-capable medium.
