Title (EN) HIGH-QUALITY HOLE CUTTING USING VARIABLE SHIELD GAS COMPOSITIONS
(FR) DÉCOUPAGE DE TROU DE HAUTE QUALITÉ AU MOYEN DE COMPOSITIONS DE GAZ DE PROTECTION VARIABLES
Abstract:
(EN) A method and apparatus for a plasma torch system having a plasma torch tip configuration that includes a nozzle, an electrode, and a control unit for controlling a composition of the shield gas flow, such that while cutting the contour the shield gas flow comprises a first shield gas composition and while cutting the hole the shield gas flow comprises a second shield gas composition.
(FR) L'invention concerne un procédé et appareil destinés à un système de torche à plasma présentant une configuration d'extrémité de torche à plasma comprenant une buse, une électrode et une unité de réglage. L'unité de réglage est destinée à régler une composition du flux de gaz de protection, de sorte que, pour le découpage du contour, le flux de gaz de protection comprenne une première composition de gaz de protection et, pour le découpage du trou, le flux de gaz de protection comprenne une seconde composition de gaz de protection.
