Abstract

L'invention concerne une buse pour torche à arc plasma. La buse comprend un corps de buse allongé sensiblement creux pouvant recevoir une électrode, le corps définissant un axe longitudinal, une extrémité distale et une extrémité proximale. La buse comprend également un manchon de turbulence pouvant être fixé à une surface intérieure du corps de buse, le manchon de turbulence étant configuré pour imprimer un mouvement tourbillonnant à un gaz introduit dans la buse. La buse comprend en outre un embout de buse raccordé à l'extrémité proximale du corps de buse, un protecteur de buse, et un isolateur configuré pour raccorder l'embout de buse et le protecteur de buse afin d'isoler électriquement l'un de l'autre le protecteur de buse et l'embout de buse tout en transférant de l'énergie thermique entre eux.
