Abstract: The device comprises a cathode unit (1) with a casing (3) and with an electrode (6) provided with a conical portion (19), and an anode unit (2) with a casing (20) and with a nozzle (12) in which is situated the conical portion (19) of the electrode (6) and which has, consecutively arranged, a cylindrical chamber (11), a conical chamber (21), a combustion chamber (7) and a plasma jet forming chamber (23). The smaller base of the conical portion (19) of the electrode (6) acts as a face-end of the electrode (6) which is placed in the cylindrical (11) and conical (21) chambers so that the distance from the face-end of the electrode (6) to the combustion chamber (7) equals 0.1-0.5 of the length of the conical chamber (21), whereas the length of the conical portion (19) of the electrode (6) equals 3.5-4.5 of the diameter of the electrode (6).
