Abstract
PURPOSE:To eliminate the over-thrust at the starting and to cause transfer to the arc in a short time by setting >=1 of the respective set values of the peak current, background current, pulse width and pulse frequency of the pulses at the arc starting larger than the set values in a steady time. CONSTITUTION:Before a wire 1 arrives at base materials 3, the pulse-like voltage of which only the set value of the background current is set larger than the set value in a steady time is applied to the wire and the wire feeding is started. When the wire 1 short-circuits to the base materials 3, the set value of the background current in particular is set larger and therefore the input heat to be applied upon the wire 1 is larger than that in the prior art, whereby the wire 1 is melt-cut easily and is transferred to the arc in a short time. In the case when the pulse width and the pulse frequency are increased similarly, the heat input upon the wire 1 is also increased and the wire 1 is easily melt-cut and is transferred to the arc in a short time. According to these methods, the wire feed troubles such as buckling of the wire owing to the failure in the arc starting are eliminated.
