Abstract

L'invention concerne une torche à plasma du type comportant :
- deux électrodes (5 et 6) tubulaires et coaxiales, en prolongement l'une de l'autre, chaque électrode étant agencée dans un support (3 et 4) ;
- des moyens de refroidissement desdites électrodes parcourus par un fluide, lesdits moyens d'au moins une électrode comprenant une chambre cylindrique étanche (16), prévue dans le support correspondant et séparée par une paroi cylindrique partageant la chambre en deux espaces annulaires (16A et 16B) en communication et à travers lesquels circule ledit fluide de refroidissement ;
- des moyens (9) pour amorcer un are électrique entre les électrodes ;
- des moyens (11,13) pour injecter un gaz plasmagène entre les électrodes ; et, - des moyens à bobine électromagnétique pour déplacer les pieds d'accrochage dudit arc électrique sur les surfaces internes desdites électrodes.
Selon l'invention, le fluide de refroidissement de ladite électrode, dont la chambre étanche (16) comporte la paroi de séparation, est électriquement isolant et ladite bobine électromagnétique (15) fait l'office de la paroi de séparation.
