Abstract
A nozzle cleaner having a configuration for centering a cutter thereof with respect to a welding nozzle. The nozzle cleaner peels off sputter from an inner peripheral surface of a welding nozzle by inserting the cutter toward the inner peripheral surface of the welding nozzle, and then rotating the cutter. The nozzle cleaner includes a guide mechanism to center the welding nozzle with respect to the cutter. The guide mechanism includes an insertion-side roller unit and a cutter-side roller unit, each having a pair of guide rollers having a smaller diameter portion and a pair of enlarged diameter portions. The enlarged diameter portions guide the welding nozzle to the vicinity of the central position of the corresponding smaller diameter portion. The facing guide rollers of the cutter-side roller unit and of the insertion-side roller unit are arranged in arrangement directions orthogonal to each other, respectively.
