Abstract
There is provided an arc welding control method of feeding a welding wire according to a push-pull feeding control using a push-side feeding motor which rotates in a forward feeding direction at a feeding rate set to a push feeding-rate setting value and a pull-side feeding motor which alternates a forward feeding rotation and a reverse feeding rotation periodically, and generating short-circuiting periods and arc periods to perform welding. An average feeding rate of the pull-side feeding motor is detected. The push feeding-rate setting value is corrected to the detected average feeding rate of the pull-side feeding motor.
