PLUG PART AND SOCKET PART FOR DETACHABLY CONNECTING A PIPE ELBOW OF A WATER-COOLED WELDING TORCH AND CONNECTING DEVICE

摘要

The invention relates to a plug part (21) for detachably connecting a pipe elbow (19) of a water-cooled welding torch (7) to a socket part (34) arranged on a hose package (20), having a cylindrical pipe element (22) with an axially running channel (23) for a welding rod (9) and a protective gas (5) and having at least two cooling channels (29, 30) for supplying and returning a cooling fluid, and a union nut (24) rotatably arranged on the pipe element (22), said union nut having an internal thread for connection to a mating external thread on the socket part (34), said invention further relating to such a socket part (34). In order to produce an optimal connection between the pipe elbow (19) and the hose package (20), a flange (25) having at least one receiving opening for receiving a pin-like element (36) of the socket part (34) is arranged on the pipe element (22) of the plug part (21) in order to fix at least one angular position of the pipe elbow (19).
