<p>PROBLEM TO BE SOLVED: To provide a weld rod feeder of a welding machine, that can hold an appropriate distance between welding poles and also achieve downsizing.SOLUTION: A weld rod feeder 1 of a welding machine that feeds a weld rod 4 includes: a main body 9; a telescopic mechanism 5 which is mounted on a main body side and has a telescopic part 10 capable of being extended and retracted in a feeding direction P of the weld rod; a first clamp 6 which is attached to the telescopic part and capable of gripping the weld rod; and a second clamp 7 which is mounted on the main body side and capable of gripping the weld rod. Further, the telescopic part is extended or retracted in a state that the weld rod is gripped by the first clamp and released by the second clamp, and the telescopic part is retracted or extended in a state that the weld rod is released by the first clamp and gripped by the second clamp, and by repeatedly extending and retracting the telescopic part, the weld rod is being fed.</p> |
