The invention relates to a cleaning apparatus () for cleaning welding torches (), comprising at least two coils () and an opening () in order to introduce the welding torch () for the electromagnetic cleaning thereof, a supply device () connected to the coils (), and optionally an apparatus for applying a cleaning fluid to the tip of the welding torch (), wherein preferably all components are disposed in a common housing () and regulated by a controller (), and to a corresponding method for cleaning welding torches (). In order to increase the cleaning quality and the cleaning range, according to the invention the coils () can be supplied independently of each other with electrical energy by the supply device () for the purpose of cleaning the welding torch (), and a cooling apparatus () is provided for cooling the coils ().

Apparatus and method for cleaning welding torches

The invention relates to an arrangement and a method for measuring a protective gas () used in an arc-welding process by analyzing the protective gas () escaping from a gas nozzle () of a torch (), wherein at least one sensor () is arranged in an external measuring device () for protective-gas analysis. For rapid, exact and practical determination and correspondingly effective evaluation of the protective effect of the protective gas, at least one sensor () is arranged in an external measuring device () for protective-gas analysis, which sensor () is positioned at a distance () from the torch () which substantially equals the distance () between the torch () and a workpiece () in a welding process so that the escape and effect of the protective gas () of an actual welding process can be simulated, and that at least one sensor () is connected to an evaluation unit () and via the latter to a welding device ().
