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. A torch fitted with an automatic ignition device tick allowing inflammation without difficulty of the mixture combustible gas required for flame cutting, welding or when metals are reheated, the said ignition goes away reliably killing is properly synchronized by the operation of a valve which is mandatory open to ensure pressurized fluid supply used for the operation. It is actually the energy so much of the fluid supply pressure that is used for ignition. The auto-ignition torch has considerable advantages in terms of construction, manufacturing, cost price and longevity.
