A welding or cutting tool for welding or cutting electrically conductive workpieces includes a nozzle arranged on a tool tip for discharging a welding or cutting beam and a nozzle cap which at least partly surrounds the nozzle, is open towards the tool tip, and has an electrode that forms a capacitance with the respective workpiece and an insulating element that electrically insulates the electrode from the other components of the tool. The electrode consists of a first electrically conductive ceramic material and is formed integrally with the insulating element, which consists of a second electrically insulating ceramic material.

Welding or cutting tool

The invention relates to a drive apparatus () for the linear movement of a processing tool with respect to a workpiece, having a tool holder () which is fixed on a carriage () and is intended for the fastening of the processing tool, having a stationary guide device () in which the carriage () is guided such that it can be displaced in a vertically linear manner, and having a drive device () with a first force transmission means () which, in an engaged position, engages with a second force transmission means () connected to the carriage () in order to move the carriage (). According to the invention, it is provided that the drive device () is mounted in the guide device () such that it can be moved between a release position, in which the force transmission means () do not engage with one another, and the engaged position in such a way that the gravitational force of the drive device () causes a movement from the release position into the engaged position.

Drive apparatus having a force transmission means that can be moved by gravitational force

A welding or cutting device for welding or cutting electrically conductive work pieces has a pipe that accommodates feed lines, a nozzle for exit of a welding or cutting jet, such as a flame, for example, disposed at an end of the pipe, forming a device tip with its free end, and an inductive sensor device for measuring the distance between the device tip and the work piece. The sensor device has at least one magnetic coil, the windings of which run about a longitudinal device axis. The sensor device is a separate module, which is pushed onto the pipe and/or the nozzle, and releasably connected with the pipe and/or the nozzle.
