ABSTRACT:
Disclosed is the powder feeder in which the duty ratio X.sub.T corresponding to the target feed amount Q.sub.T is calculated on the basis of the calibration curve obtained by the feeder calibration which is conducted before the start of powder feed, and the powder P starts to be fed according to the duty ratio X.sub.T, therefore, the actual feed amount can reach to the target feed amount Q.sub.T in a short time (within the time T.sub.1) from the start of powder feed, and the powder P can be fed while controlling the actual feed amount with high accuracy, and further the powder P can be precisely fed even in case of the short time feed for several seconds.
