Abstract

L'invention concerne une buse d'allumage pour torche comportant un tube interne (1) et un tube externe (2) dont les extrémités antérieures forment une zone d'étincellage.
Un isolant électrique (3) sépare les deux tubes (1 et 2) à l'exception de la zone d'étincellage (S) et les extrémités postérieures des tubes (1 et 2) constituent des bornes de connexion à une alimentation en courant électrique.
L'invention s'applique en particulier aux torches de soudage et d'oxy-coupage.
