Abstract

Un chalumeau muni d'un dispositif d'allumage automa­ tique permettant l'inflammation sans difficulté du mélange gazeux combustible nécessaire à l'oxycoupage, au soudage ou au réchauffage des métaux, ladite inflammation s'effec­ tuant de manière fiable est convenablement synchronisée par la manoeuvre d'une vanne que l'on doit obligatoirement ouvrir afin d'assurer l'alimentation sous pression du fluide utilisé pour l'opération. C'est effectivement l'energie résul­ tant de la pression d'alimentation du fluide qui est utilisée pour l'allumage. Le chalumeau à allumage automatique présente des avantages considérables sur le plan de la construction, de la fabrication, du prix de revient et de la longévité.
