WELDING OR CUTTING TOOL

摘要

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.

1. Welding or cutting tool for welding or cutting electrically conductive work pieces, having a nozzle (18) disposed at a tool tip (18), for exit of a welding or cutting jet, and having a nozzle cap (28) that encloses the nozzle (18), at least in part, and is open toward the tool tip (16), which cap has an electrode (32) that forms a capacitance with the respective work piece, and which cap has an insulating element (34) that electrically insulates the electrode (32) relative to the further components of the tool, therein the electrode (32) comprises a first, electrically conductive ceramic material, and is Configured in one piece with the insulating element (34), which comprises a second, electrically insulating ceramic material.
