Estimating the term…
The invention relates to a cleaning apparatus (1) for cleaning welding torches (5), comprising at least two coils (4, 11) and an opening (3) in order to introduce the welding torch (5) for the electromagnetic cleaning thereof, a supply device (7) connected to the coils (4, 11), and optionally an apparatus for applying a cleaning fluid to the tip of the welding torch (5), wherein preferably all components are disposed in a common housing (2) and regulated by a controller (8), and to a corresponding method for cleaning welding torches (5). In order to increase the cleaning quality and the cleaning range, according to the invention the coils (4, 11) can be supplied independently of each other with electrical energy by the supply device (7) for the purpose of cleaning the welding torch (5), and a cooling apparatus (14) is provided for cooling the coils (4, 11).
A cleaning apparatus (1) for cleaning a welding torch (5), including at least two coils (4, 11) and an opening (3) for introducing the welding torch (5) for the electromagnetic cleaning thereof, a supply device (7) connected with the coils (4, 11), and optionally a device for applying a cleaning fluid to the tip of the welding torch (5), wherein preferably all components are arranged in a common housing (2) and controlled by a control device (8), wherein, for the cleaning of the welding torch (5), the coils (4, 11) are suppliable with electrical energy by the supply device (7) independently of one another, and wherein a cooling device (14) is provided for cooling the coils (4, 11).
A method for cleaning a welding torch (5), in which a tip of the welding torch (5) is exposed to an electromagnetic field (16) generated by at least two coils (4, 11) for the contactless removal of contaminants, wherein a cleaning fluid is optionally applied to the tip of the welding torch (5) prior to cleaning, wherein the first coil (4) for generating an electromagnetic field (16) is supplied with electrical energy after the at least one further coil (11).
