Abstract: A handheld welding torch for electric-arc welding with a melting welding wire has a wire feed unit for conveying the welding wire along a conveying axis arranged within a torch housing with a handle region, the wire feed unit including a drive unit with a rotation axis arranged vertically with respect to the conveying axis of the welding wire, a drive roller with a rotation axis and a counter roller with a rotation axis, and having a torch push-button. The wire feed unit has a gear stage and the rotation axis of the drive unit is arranged aligning with the conveying axis of the welding wire.

Abstract: A hose assembly includes a plurality of lines for supplying a welding torch with operating media, such as welding current, welding wire, protective gas and/or control signals. The lines include a coolant line for feeding cooling medium of a coolant source to a welding torch. The hose assembly has a coupling element for detachably connecting to a welding unit or to a welding torch. A further coupling element for the coolant line is integrated in the coupling element. The coupling and decoupling direction of the further coupling element is orientated transverse to the longitudinal axis of the hose assembly. The coupling elements can each be coupled and decoupled independently from each other. A plug element is used in the coupling element. The coolant line has a plug connection.

Abstract: A welding torch, in particular a handheld welding torch, for a melting welding wire, which is guided in a wire core arranged within a protective hose, fastens the protective hose and the welding core within a torch housing of the welding torch independently from one another. For minimizing stresses on the welding torch by the hose package, the protective hose is fastened rotatably and pivotably and the wire core is fastened rotatably to the torch housing.
