The invention relates to a method and an apparatus (10) for automated servicing of a torch head (12) comprising at least one contact tip (20) and a nozzle (26) surrounding the at least one contact tip (20). In a first servicing device (32) the torch head (12) is contact-freely cleaned in an assembled state of said at least one contact tip (20) and said nozzle (26). A second servicing device (34) is used for applying a torch head treatment agent (42) to at least a portion of the surfaces of said at least one contact tip (20) and said nozzle (26). The operation of the first servicing device (32) and the second servicing device (34), respectively, is started by a control unit (50) after the torch head (12) has been transferred to a corresponding servicing position. Moreover the invention relates to the use of a liquid dispersion including between about 5 and about 50 percent-by-weight of boron nitride as a torch head treatment agent for servicing of a welding torch head. |
