ABSTRAKT

The electric arc modes of operation in the plasma torch with the cylindrical anode and vortex stabilisation are studied experimentally. Three arc modes are observed but especially two are investigated: the restrike mode and the takeover mode. Particularly the attention is given to the difference of the behaviour of the arc in argon, nitrogen and mixture of argon-nitrogen. The results show that the takeover mode is characteristic for argon arc. The restrike mode occurs for specified argon arc conditions with the thermal breakdown. The restrike arc mode is typical for nitrogen and mixture of argon-nitrogen with electrical breakdown. The time of arc root displacement on anode surface and time of breakdown, the amplitude of fluctuation as functions of arc current and pressure are shown and discussed.
