Patent ID: 10376982

Abstract:
A hand tool for welding-torch maintenance, which can remove sputter adhering to a nozzle with sufficient working efficiency. The hand tool has a pair of metal stays turnably supported by a pivoting axis. The metal stays comprises grips handled by a user, 1st pinchings used for pulling a welding-wire, and 2nd pinchings used for removing sputter adhering to the nozzle. The 1st pinchings are configured so as to be inserted into the nozzle when the metal stays are closed. The 2nd pinchings have projections which are extended outside from the backs of the 1st pinchings and thrown out towards heads of the 1st pinchings. The sputter adhering to the inner-and-outer circumferential surfaces and end face of the nozzle are removed by inserting the 1st pinchings into the nozzle, inserting the end of the nozzle between the 2nd pinchings and the 1st pinchings, and moving the tool to scratch the sputter off the inner-and-outer circumferential surfaces and the end face of the nozzle.
