    摘要: A method and apparatus for operating a DC plasma torch. The power supply used is at least two times the average operating voltage used, resulting in a more stable operation of the torch. The torch can include two concentric cylinder electrodes, the electrodes can be graphite, and the plasma forming gas can be hydrogen. The power supply provided also has the capability of igniting the torch at a pulse voltage of at least 20 kilovolts.
