PROBLEM TO BE SOLVED: To provide a nut feeder for a welding machine capable of securely and stably conveying parts such as a nut to a parts consumption device through a feed hose. SOLUTION: The nut feeder for a welding machine is constituted so that a parts feeder 2 as a feed source of a nut and a nut feed head 3 provided at the side of a welding machine are connected with a feed hose 14 composed of a hollow tube, and the nut is fed to the feed head by an escape 5 provided at the side of the parts feeder through the feed hose. The parts feeder 2, the nut feed head 3 and the escape 5 are provided with sensors 21, 22 and 23 for detecting whether the nut is present or not in each region. Meanwhile, an air flow going toward the feed head for a prescribed time is formed at the inside of the feed hose; the nut is guided into the air flow by the escape 5, and the nut is conveyed to the feed head 3 through the air flow.
