Clamping device () for clamping a non-consumable welding electrode () with an electrode holder (A) which has a receiving chamber (B) aligned in the longitudinal direction for receiving a welding electrode () which is insertable therein and at its front end has an end portion (C) which widens conically towards the forward end and can be compressed by means of a clamping heat sink (D) for holding the welding electrode (), thus producing a large-surface cooling end face (KSF) for cooling the welding electrode ().

Welding torch

The invention relates to a plug part () for detachable connecting a torch neck () of a water-cooled welding torch () to a socket part () arranged on a hose package (), having a cylindrical pipe element () with an axially running channel () for a welding wire () and a protective gas () and having at least two cooling channels () for supplying and returning a cooling fluid, and a union nut () rotatably arranged on the pipe element (), the union nut having an internal thread for connection to a mating external thread on the socket part (), the invention further relating to such a socket part (). In order to produce an optimal connection between the torch neck () and the hose package (), a flange () having at least one receiving opening for receiving a pin-like element () of the socket part () is arranged on the pipe element () of the plug part () in order to fix at least one angular position of the torch neck ().

Plug part and socket part for detachably connecting a pipe elbow of a water-cooled welding torch and connecting device

The invention relates to a securing element () arranged between a gas element () and a current element () of the plug-in element (). A fixing element () is arranged in the coupling () of the torch handle and meshes with said securing element (), and, for guiding over said fixing element () arranged in the coupling (), the gas element () has a diameter smaller than those of the securing element () and of the current element (). Said securing element () can be guided over the fixing element () using a flat area (), while the gas element () is arranged in a gas bore hole () in the coupling () in a sealing manner. The position of the torch body () can be freely adjusted by means of a manual rotational movement, said fixing element () being guided in a circumferential groove () in said securing element ().
