Plasma probe and method for assembly of its electrode

Abstract

A plasma probe comprises a hose with a conductor arranged therein that supports an electrode at least at its distal end. The electrode is either directly secured on the conductor or the conductor is provided with a plastic sheathing at least at its distal end by means of which the electrode is held. The electrode can be inserted between the conductor and the plastic sheathing and can be clamped in this manner. After first use the plastic sheathing can be fused to the electrode. The conductor is placed with clearance inside a channel or hollow space of electrode, however, whereby also in case of spot-like contact between the conductor and the electrode due to the gap provided between them apart therefrom the heat transmission from the electrode on the conductor is impeded and thereby the heat introduction in the plasma probe is limited.
