摘要

The unit (1) for generation of thermal arc plasmas comprises a first neutral segment (13) dividing the arc burning space into an anode space (17) and a cathode space (15). The anode and cathode spaces are joined to one another by means of at least one connector channel (19) in such a way that flow of the main plasma gas from the anode space into the cathode space is at least to a large degree prevented.
