Abstract
An electrode for a plasma torch and a plasma torch head comprise an elongated electrode holder with a front surface on the electrode tip and a hole arranged in the electrode tip along a central axis through the electrode holder, and an emission insert arranged in the hole such that an emission surface of the emission insert is exposed. The emission surface is set back relative to the front surface of the electrode holder. An electrode for a plasma torch and a plasma torch head also comprise an electrode socket and an electrode holder, the electrode socket having an internal thread, and the electrode holder having an external thread and an O-ring in a groove in the cylindrical outer surface. The electrode holder is screwed together with the electrode socket via the external thread and the internal thread and sealed by means of the O-ring.
