Webability to control the plasma redox potential by varying carbon dioxide-hydrocarbons ratio in the initial gas mix-ture [4]. For materials processing and waste treatment, higher power torch with larger plasma volumes is desired. At the Centre for Advanced Coating Technologies (CACT) a new high power DC torch with graphite cathode was de- WebWe have developed a new dc plasma torch which is operated with a mixture of carbon dioxide and hydrocarbons, e.g., methane. Erosion of the graphite cathode is continually compensated by the deposition of carbon ions. The torch is typically operated at low currents and, due to the nature of the gases, high voltage.
