Abstract

L'invention concerne une torche à plasma, du type comportant :
- deux électrodes tubulaires et coaxiales, en prolongement l'une de l'autre, chaque électrode étant agencée dans un support (3,4) dans lequel est ménagé un circuit de refroidissement (8,9) de l'électrode correspondante ;
- des moyens pour amorcer un arc électrique entre les deux électrodes par court-circuit temporaire de celles-ci ; et, - des moyens pour injecter un gaz plasmagène entre les deux électrodes.
Selon l'invention, pour produire l'amorçage de l'arc électrique entre les deux électrodes, au moins l'une (5) desdites électrodes est mobile axialement, entre une position de fonctionnement de la torche, pour laquelle ladite électrode mobile (5) est éloignée de l'autre électrode (6), et, une position d'amorçage, pour laquelle ladite électrode mobile est au contact de l'autre électrode en établissant un court-circuit électrique, de façon à
engendrer ledit arc électrique (10) dès la rupture du court-circuit électrique, lorsque ladite électrode mobile (5) est ramenée vers sa position de fonctionnement.
