摘要：In an arc welding control method of repeating a short circuit and an arc toperform welding, control is carried out to conduct a welding current having a firstpolarity for a short circuit period, and a first commutation to commutate the weldingcurrent from the first polarity to be a polarity of the welding current for the short circuitperiod to a second polarity to be opposite to the first polarity is carried out for an arcperiod subsequent to the short circuit period. Furthermore, control is performed to carryout a second commutation to commutate the welding current from the second polarityto the first polarity for the arc period in which the first commutation is executed.Consequently, it is possible to reduce an energy input amount to a base metal, therebysuppressing burn-through in welding of a thin plate.
