摘要： An arc welding apparatus includes: a switching device connected to both terminals of a secondary winding of a transformer whose opposite primary winding serves as a smoothing reactor on an inverter's secondary side; an output voltage detector detecting an output voltage between a welding wire and a workpiece; and a control circuit controlling the switching device and a circuit on the inverter's primary side. The control circuit includes: a first control portion that turns off the circuit on the inverter's primary side and turns on the switching device when the output voltage detected by the output voltage detector rises to a first predetermined voltage; and a second control portion that turns on the circuit on the inverter's primary side and turns off the switching device after a lapse of a predetermined time after the switching device is turned on.
