Abstract: Provided for herein is an apparatus that includes a machine-side connection housing. The machine-side connection housing includes a machine-side connection configured to provide a welding consumable or an electrical connection to a welding/cutting torch head. The apparatus also includes a fume extraction connection housing that includes a fume extraction connection to a fume extraction device. A flexible connection is arranged between the machine-side connection housing and the fume extraction connection housing. A seal that includes a first orifice is arranged between the fume extraction connection and the machine-side connection. Finally, a conduit, configured to connect the machine-side connection to the welding/cutting torch head, is arranged to pass through the first orifice, through the flexible connection and through the fume extraction connection housing to the welding/cutting torch head.

Abstract: The invention relates to a coupling for power cables, consisting of a plug part and a socket part, said plug part having a basic body comprising a coupling pin on which a locking pin is arranged. The locking pin is movably mounted on the coupling pin so as to be displaceable in the axial direction of the coupling pin. The locking pin is biased to a basic position towards a back end of the coupling pin by a spring force. When the coupling is being locked, the locking pin engages a helical groove of the socket part and, thus, moves towards the front end of the coupling pin. This movement causes the spring device to load.

Abstract: The invention relates to a coupling for power cables, consisting of a plug part (1) and a socket part, said plug part (1) having a basic body (2) comprising a coupling pin (3) on which a locking pin (4) is arranged, said locking pin (4) being mounted in the plug part (1) so as to be displaceable in the axial direction of the coupling pin (3), said locking pin (4) being held in a basic position towards a back end (11) of the coupling pin (3) by a spring force and, while the coupling is being locked, being moved by interlocking with a helical groove of the socket part towards the front end (12) of the coupling pin (3) and a spring device (16) being loaded in the process.

Abstract: The invention relates to a hand welding torch (10) provided with a switching device (15), wherein the switching device is formed from a switching element and actuators, wherein the switching element is mounted in such a manner that it can move relatively to the actuators, wherein the actuators can be actuated by means of the switching element, and wherein the switching element can be moved in at least two degrees of freedom.
