OM-201 872 Page 6 D N’approchez pas le tube du chalumeau et l’arc pilote lorsque la gâ- chette est enfoncée. D Le câble de masse doit être pincé correctement sur la pièce à cou- per , métal contre métal (et non de telle sorte qu’il puisse se détacher), ou sur la table de travail le plus près possible de la ligne de coupage.
OM-201 872 Page 7 D Les bouteilles ne doivent pas être près de la zone de coupage ni de tout autre circuit électrique. D Un contact électrique ne doit jamais se produire entre un chalumeau de plasma d’arc et une bouteille. D Ne coupez jamais sur une bouteille pressurisée − une explosion en résulterait.
