Abstract: A wire feeder (300) includes a cross table (302) placed to be movable in the back-and-forth direction along a wire feed direction (D), and upper and lower tables (304, 305) which can move in the up-and-down direction along a direction perpendicular to the wire feed direction with respect to the cross table (302). Feed rollers (320, 321) for feeding a wire are rotatably mounted on the upper and lower tables (304, 305). A wire guide (330) integrally formed from upstream to downstream along the wire feed direction (D) with respect to the feed rollers (320, 321) is placed, together with the feed rollers (320, 321), on a wire axis extending from the cross table 302 to the upper and lower tables (304, 305) to be movable in the back-and-forth direction and up-and-down direction.
