ABSTRACT:
Plasma burner provided with an electrode holder for the support of a cently arranged electrode and an outer electrode, a device for applying an electrical voltage for producing an electric arc between the electrodes and a device for the supply of gas to the electric arc area of the electrodes. The electrodes constitute a continuously consumable electrode system in which the outer electrode has the shape of a pipe while the other electrode is pipe- or rod-shaped and coaxially arranged within the outer electrode so as to define therebetween a passage of annular cross-section. The electrode holder is designed to conduct gas through the passage forwards to a front, free end of the electrodes where the electric discharge occurs from the end of the inner electrode.
