PLUG PART AND SOCKET PART FOR DETACHABLY CONNECTING A TUBE ELBOW OF A GAS-COOLED WELDING TORCH TO A HOSE PACKET, AND CONNECTING DEVICE WITH SUCH A PLUG PART AND SOCKET PART

摘要

The invention relates to a plug part (21) for detachably connecting a tube elbow (19) of a gas-cooled welding torch (7) to a socket part (34) disposed on a hose packet (20), comprising a cylindrical tube element (22) with a flange (25) and with an axially extending channel (23) for a welding wire (9) and for a protective gas (5) and comprising a coupling nut (24) which is rotatably disposed on the tube element (22) and which comprises an inner thread for connection to a corresponding outer thread on the socket part (34). The invention also relates to such a socket part (34). The aim of the invention is to produce an optimal connection between the tube elbow (19) and the hose packet (20). This is achieved in that a bevel (32) is disposed on the flange (25) of the tube element (22) of the plug part (21), and the end piece (35) of the socket part (34) has at least one axial slot (39).
