Abstract

A non-consumable electrode pulse arc welding control method is provided for welding by conducting a welding current made up a peak current during a peak period and a base current during a base period. By the method, a peak current setting signal Ipr, a base current setting signal Ibr, and a current slope factor G (0 < G < 1.0) are set. The welding current is detected and a current detection signal Id is outputted. During the peak period, a first current setting signal is calculated based on a formula (Ipr-Id)×G+Id every control cycle, and the welding current is controlled based on the calculated first current setting signal. During the base period, a second current setting signal is calculated based on a formula (Ibr-Id)×G+Id every control cycle, and the welding current is controlled based on the calculated second current setting signal.
