The invention relates to a plug part (21) for detachably connecting a torch neck (19) of a gas-cooled welding torch (7) to a socket part (34) disposed on a hose package (20), comprising a cylindrical pipe 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 union nut (24) which is rotatably disposed on the pipe 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 torch neck (19) and the hose package (20). This is achieved in that a bevel (32) is disposed on the flange (25) of the pipe element (22) of the plug part (21), and the end piece (35) of the socket part (34) has at least one axial slot (39).
1-19. (canceled)
A plug part (21) for detachably connecting a torch neck (19) of a gas-cooled welding torch (7) to a socket part (34) arranged on a hose package (20) if need be by interconnecting a torch housing (7′), having a cylindrical pipe element (22) with a flange (25) and an axially extending channel (23) for a welding wire (9) and a protective gas (5), and a coupling nut (24) rotatably arranged on the pipe element (22), said coupling nut (24) having an inner thread for connection to a corresponding outer thread on the socket part (34), wherein a bevel (32) is disposed on the flange (25) of the pipe element (22).
A socket part (34) for detachably connecting a hose package (20) to a plug part (21) arranged at a torch neck (19) of a gas-cooled welding torch (7), having an at least partially cylindrically formed end piece (35) with an axially extending channel (37) for a welding wire (9) and a protective gas (5), and an outer thread for connection to a corresponding inner thread of a coupling nut (24) of the plug part (21), wherein a bevel (45) corresponding with a bevel (32) on the flange (25) of a cylindrical pipe element (22) of the plug part (21) to be connected is disposed on the end piece (35), and wherein the end piece (35) comprises at least one axial slot (39).
