A pulse arc welding control method using a pulse arc welding device that welds an object by generating an arc between a welding wire and the object , the method comprising: controlling the pulse arc welding device so as to weld the object by removing, from the welding wire , a molten droplet produced by melting the welding wire by applying a welding voltage (V) between the welding wire and the object and allowing a welding current (I) to flow through the welding wire such that the welding current (I) alternately repeats, at pulse frequency (PHz), a peak current period (IPT, IPT1, IPT2, TP) in which the welding current (I) is a peak current (IP) and a base current period (IBT, IBT1, IBT2) in which the welding current (I) is a base current (IB) smaller than the peak current (IP); characterized in that the pulse arc welding control method further comprises: determining a removal time point (td) at which the molten droplet is removed from the welding wire ; and in a case where the removal time point (td) is not in the base current period (IBT, IBT1, IBT2), adjusting a pulse waveform parameter which is at least one of the peak current (IP) and the peak current period (IPT, IPT1, IPT2, TP) and adjusting the pulse frequency (PHz) based on a predetermined relationship between the pulse frequency (PHz) and the pulse waveform parameter so as to cause the removal time point (td) to be in the base current period (IBT, IBT1, IBT2). controlling the pulse arc welding device so as to weld the object by removing, from the welding wire , a molten droplet produced by melting the welding wire by applying a welding voltage (V) between the welding wire and the object and allowing a welding current (I) to flow through the welding wire such that the welding current (I) alternately repeats, at pulse frequency (PHz), a peak current period (IPT, IPT1, IPT2, TP) in which the welding current (I) is a peak current (IP) and a base current period (IBT, IBT1, IBT2) in which the welding current (I) is a base current (IB) smaller than the peak current (IP); characterized in that the pulse arc welding control method further comprises: determining a removal time point (td) at which the molten droplet is removed from the welding wire ; and in a case where the removal time point (td) is not in the base current period (IBT, IBT1, IBT2), adjusting a pulse waveform parameter which is at least one of the peak current (IP) and the peak current period (IPT, IPT1, IPT2, TP) and adjusting the pulse frequency (PHz) based on a predetermined relationship between the pulse frequency (PHz) and the pulse waveform parameter so as to cause the removal time point (td) to be in the base current period (IBT, IBT1, IBT2). determining a removal time point (td) at which the molten droplet is removed from the welding wire ; and in a case where the removal time point (td) is not in the base current period (IBT, IBT1, IBT2), adjusting a pulse waveform parameter which is at least one of the peak current (IP) and the peak current period (IPT, IPT1, IPT2, TP) and adjusting the pulse frequency (PHz) based on a predetermined relationship between the pulse frequency (PHz) and the pulse waveform parameter so as to cause the removal time point (td) to be in the base current period (IBT, IBT1, IBT2). <EOS>
