Abstract (en)
[origin: CA2856500A1] The invention relates to a method of cleaning a torch of a plasma coating plant. The invention is based on a method of cleaning a torch (13) of a plasma coating plant in which the torch (13) is impinged by a cleaning agent (30) exiting from a cleaning nozzle (28) during an interruption of a coating process, this means during a phase in which no layer is applied onto a work piece. In this way spray material particles (32) adhering to the torch (13) are removed. In accordance with the invention the cleaning agent (30) is designed in such a way that it changes into a gaseous state after exiting the cleaning nozzle (28). The cleaning agent is, for example, dry ice, liquid nitrogen, liquid oxygen or liquid carbon dioxide.
