Embodiment Construction

[0037] figure 1 A welding device 1 is shown for use in various processes and / or methods, such as MIG / MAG, WIG / TIG, electrode, twin wire / tandem welding methods, plasma or soft soldering methods, etc.

[0038] The welding device 1 includes a power source 2 in which a power unit 3 is arranged, a control device 4 and other components and circuits not shown, such as switching elements, control valves and the like. The control device 4 is connected, for example, to a control valve arranged between the gas tank 6 and the welding torch 7 for the shielding gas 5 (eg CO 2 , helium or argon, etc.) in the supply line.

[0039] Furthermore, the device 8 for supplying the welding wire 9 from the storage drum 10 and / or the wire roller to the region of the welding torch 7 can be controlled by the control device 4, as in eg MIG / MAG welding. It should be understood that the supply device 8 can also be integrated in the welding device 1, in particular in the housing 11 of the current source 2,...

Abstract

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).

Description

technical field [0001] The invention relates to a plug part for the detachable connection of the torch neck of a gas-cooled torch to a socket part arranged on a hose pack, optionally by interconnecting the torch housing, The plug part has a cylindrical tube element with a flange and axially extending channels for welding wire and shielding gas, and a union nut which is rotatably arranged on the tube element Above, the union nut has internal threads for connection to corresponding external threads on the socket part. [0002] Furthermore, the invention relates to a socket part for detachably connecting a hose pack to a plug part arranged on the torch neck of a gas-cooled welding torch, which socket part has an at least partially cylindrical A ground-formed end piece having an axially extending passage for welding wire and shielding gas and an external thread for a corresponding internal thread of a union nut connected to said plug part. [0003] Finally, the invention relates...
