The present invention provides a pulsed arc welding method of carbon oxide. A peak period (Tp) of a peak current flow (Ip) and a reference period (Tb) of a reference current flow (Tp) are used as one pulse period (Tpb) for welding repeatedly. The peak current (Ip) is vibrated through an amplitude (Ws) and a vibration period (Ts) in a peak period (Tp) for forming a molten drop at a front end of a welding wire.
