Essay

Dissertation is devoted to increase of efficiency of plasma-machining high-strength steels and alloys due to perfection of plasma source of heating. The method of calculation it is developed of plasmatrons with hollow electrodes for plasma-machining, which allowed to develop hi-tech plasmotron with hollow "cold" electrodes, working both on a line, and on reverse polarity of connecting to the source of power supply.
