Wire feeding system and welding system

Abstract

A wire feeding system includes a first feeder provided with a first feeding motor that feeds a wire in a wire feeding direction, a second feeder spaced apart from the first feeder in the wire feeding direction and provided with a second feeding motor that feeds the wire in the wire feeding direction, and a controller that controls the rotation speed of the first feeding motor based on a first speed command and controls the rotation speed of the second feeding motor based on a second speed command. The controller gradually changes the second speed command over time when an amount of change of the second speed command is not within a predetermined range.
