  • the rate of plasma outflow is large, and the decrease in the rate of plasma collapse is large. Therefore, in the proposed method, and for lesser thicknesses, there must be a large velocity of plasma outflow, i.e. white hardness of plasma flow.
  • the best way is to convert the electrical energy of the plasma into thermal energy. Thermal energy melts the metal in the area of the cut, and the kinetic energy of the plasma blows this molten metal from the cut. Therefore, the angle of the input of the food must be removed in such a way that the molten metal is removed from the cutting area without having to put the burner in the lower part of the appliance.

Abstract

L'invention concerne la production de plasma et la commande du plasma ainsi que le soudage et le découpage au plasma. Le procédé de production de plasma consiste à fournir de l'argon et de l'hydrogène dans la zone d'excitation de l'arc principal, formée par une électrode disposée coaxiale dans la buse. L'argon est fourni dans la zone de l'arc axialement le long de l'axe de l'électrode de tungstène, et l'hydrogène l'est tangentiellement à la surface interne de la buse de formation de plasma. Cela permet d'obtenir un plasma à température élevée et à forte concentration qui a une charge calorifique importante, ce qui permet de couper des métaux d'épaisseurs différentes avec une grande efficacité et une qualité élevée des bords découpés.
