Claim 2:
3. The method of claim 1, wherein a slope of the welding current in the current decreasing section, the slope being an amount of change in the welding current per unit time, is in a range of from −200 A/ms to −50 A/ms,
wherein a separation maintaining time Th1 of the welding current in the current maintaining section is in a range of from 2 ms to 8 ms,
wherein a slope of the welding current in the current increasing section is in a range of from 50 A/ms to 300 A/ms, and
wherein the separation maintaining time Th1 in ms, a wire diameter d in mm, and the wire feeding speed Fs in in/min in the current maintaining section satisfy the following relationship (1):

0.4≤(1.2/d)×(Fs/15)×Th1≤10  (1).
