Definitions
- an arc the so-called auxiliary arc
- a gas stream is brought into contact with the auxiliary arc and passed through the nozzle electrode in order to drive the plasma formed by the auxiliary arc to the third electrode.
- the direct current source not only serves to maintain the auxiliary arc between the first and second electrodes, but above all also to heat the plasma formed by the arc and driven to a third electrode.
- the current source applied between the second electrode and the third electrode can either be a direct current source or, e.g. in DE-PS 14 40 594 proposed to be an AC power source.
- the dimensioning of the annular gap between the nozzle electrode and the Auxiliary electrode Due to the conical design of the auxiliary electrode and the central channel, the cold gas used for plasma formation is optimally introduced into the conical area serving as the combustion chamber for the pilot arc through the cylindrical gap formed in the process.
- An annular channel or an annular gap 9 adjoins the nozzle electrode 2, which in turn is delimited by the burner nozzle 3.
- the nozzle 3 has in the area of the outer plasma channel boundary, i. H. in the direction of the end face 11 of the plasma torch 15 on its inside an electrically insulating layer 10, which effectively prevents the formation of parasitic arcs.
