Problems solved by technology

Furthermore, the disadvantage of conventional water-cooled torches is that the cooling system must be switched off once the torch neck is changed or simply twisted
[0006] Known connections between the torch neck of the welding torch and the hose package and / or the torch housing often only meet some of the requirements mentioned and are relatively complex to handle

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 power source 2, i...

Abstract

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).

Description

technical field [0001] The invention relates to a plug part for detachably connecting the torch neck of a water-cooled welding torch to a socket part arranged on a hose package, if necessary by interconnecting the torch housing, the plug part having a cylindrical A body tube element having axially extending channels for welding wire and shielding gas and having at least two cooling channels for supplying and returning cooling fluid, and a union nut, said union nut being rotatable Arranged on the pipe element, the union nut has an internal thread for connection to a mating external thread on the socket part, wherein the orifices of the at least one cooling channel for supplying cooling fluid are separately layout. [0002] Furthermore, the invention relates to a socket part for detachably connecting a hose pack to a torch neck of a water-cooled welding torch, which socket part has: an end part which is at least partially formed cylindrically, The end piece has axially extendi...
