Title (EN) METHOD AND DEVICE FOR PLASMA CUTTING OF WORK PIECES
(FR) PROCÉDÉ ET DISPOSITIF DE DÉCOUPE DE PIÈCES À USINER AU PLASMA
Abstract:
(EN) The present invention relates to a method and device for CO2 plasma cutting of a work piece, using a plasma cutting torch, wherein an arc is generated between the cutting head and the work piece, and a shielding gas is provided around the arc, characterized in that the shielding gas comprises CO2-snow or a mixture containing CO2-snow.
(FR) La présente invention concerne un procédé et un dispositif de découpe au plasma de CO2 d'une pièce à usiner, à l'aide d'une torche de découpe au plasma, un arc étant généré entre la tête de coupe et la pièce à usiner et un gaz de protection étant disposé autour de l'arc, ledit gaz étant caractérisé en ce qu'il contient de la neige de CO2 ou un mélange contenant de la neige de CO2.
