Abstract: A preferred embodiment of the subject electrical arc-welding gun cleaning tool for removing welding splatter from the welding tip and nozzle of a wire-feed arc-welding gun is described. The tool comprises a cleaning tool base 52 connected to a drive means 90 for rotating the base 52 in a desired direction about a drive axis. A conical spiral spring 64 is attached to the base 52 for insertion into the arc-welding gun nozzle 33. The rotating spring 64 surrounds the welding tip 40 and expands to also contact the inner surface of the inner surface 36 of the arc-welding gun nozzle 33. The spring 64 removes accumulated welding splatter as it rotates. A cylindrical tube 82, with serrations 86 at a receiving end 84, limits penetration of the spring 64 into the arc-welding gun nozzle 33 while also removing welding splatter from the outer end 43 of the welding tip 40.
