Abstract

Die Erfindung betrifft eine Einrichtung (2), insbesondere einen Brenner (7) zur Erzeugung von Plasma zum Schweißen, Schneiden, Härten oder Sterilisieren von zu bearbeitenden Objekten (37) bzw. von zu behandelnden Materialien, mit wenigstens einer Elektrode (27) zum Anlegen eines Spannungspotentials einer Stromquelle, um wenigstens einen Lichtbogen (40) zwischen einer durch unterschiedlich gepolten Elektroden (27) aufgebauten Kathoden-Anodenstrecke (39) aufzubauen. Wenigstens eine von zwei unterschiedlich zu polenden Elektroden (27) oder wenigstens ein Teilbereich der Kathoden-Anodenstrecke (39) ist dabei von einem eine Ausnehmung (43) aufweisenden Umgrenzungselement (42), welches im Zusammenwirken mit der Objektoberfläche eine Hohlkammer (41) ausbildet, zumindest teilweise umgeben bzw. umhüllt. Die Hohlkammer (41), welche objektseitig unmittelbar durch die Objektoberfläche begrenzt wird, ist zum Aufbau des Lichtbogens (40) ausgebildet.
