Abstract

Plasmaelektrode für eine Schneidvorrichtung, welche aus einem Elektrodenkörper mit einer axialen, zentrischen Aufnahme für einen stirnseitig dort abgeordneten Elektrodenkern besteht, wobei im Innenraum des Elektrodenkörpers ein radial innen liegender Flüssigkeitskanal durch ein austauschbares Kühlrohr gebildet ist, durch welchen ein Kühlflüssigkeitsstrom in axialer Richtung fließt, wobei das Kühlrohr durch einen oder mehreren Anschläge am Elektrodenkörper positioniert ist und dessen vordere, dem Elektrodenkern nächstliegende Stirnseite in eine ringförmigen Ausnehmung des Elektrodenkörpers eingreift, in welcher der Kühlflüssigkeitsstrom in Pfeilrichtung umgelenkt ist, wobei auf der Innenseite des Elektrodenkörpers mindestens ein radial oder axial gerichteter Anschlag für das Kühlrohr angeordnet ist, der mit der vorderen Stirnfläche des Kühlrohrs zusammenwirkt.
