Welding torch grip

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.

Handheld welding torch for electric-arc welding

A system for mounting a wire core for a welding wire in a coupling of a hose assembly, wherein the wire core is fixed with a wire inlet nozzle in the coupling and the wire inlet nozzle is connected to the coupling by way of a mounting element which is formed in a cylindrical manner and has at least one slot to form at least two movable jaws and a wire inlet nozzle for such a mounting system are disclosed. At the end opposite from a wire inlet element, the mounting element is provided with an oval flange, which oval flange is formed in a raised manner with respect to the cylindrical region.

The invention relates to a water-vapor plasma torch () for cutting a workpiece (), comprising a feed line () for a liquid (), a heating device (), and an evaporator () for forming a gas () from the liquid (), a cathode () detachably connected to a movably mounted piston rod (), and a nozzle () with an outlet opening () for the gas (), as well as to a wear-detection and process-control method to be used with such a water-vapor plasma torch (). To create such a water-vapor plasma torch () including wearing-part detection, at least one temperature sensor () is arranged within the piston rod (), said temperature sensor being connected to a control unit (), so that a wear of the cathode () and the nozzle () can be concluded from the temperature values detected, and that the control of the water-vapor plasma cutting process is influenceable.
