Abstract

The invention relates to an electrode structure for plasma cutting torches, wherein a recess or borehole open at one side in the direction of a workpiece to be processed is formed in an electrode holder or in a holding element for receiving an emission insert, in which recess or borehole the inserted emission insert can be fastened in a force transmitting manner, in a shape-matching manner and/or with material continuity. At least one pressure equalization passage and/or an at least temporarily active pressure equalization passage is present between a hollow space formed in a recess or borehole and the emission insert and the environment through the emission insert and/or between an outer jacket surface region of the emission insert and the inner wall of the recess or borehole, which is formed in the holding element or in the electrode holder (7.1). Alternatively or in addition at least one pressure equalization passage and/or a temporarily active pressure equalization passage can be present between a hollow space formed in a recess or borehole and the holding element and the environment through the holding element and/or between an outer jacket surface region of the holding element and the inner wall of the recess or borehole which is formed in the electrode element or in the holding element.
