摘要：In control applying a gradient to a command voltage value during an arc period,although stable welding can be performed even in a case where a protrusion length of awelding wire becomes long, when the disturbance such as sudden change in theprotrusion length is generated, a current waveform of the arc period is undershot, theshort circuit period is disturbed, and it took time to return to the stable state, and theamount of sputter generation is also increased. Therefore, it is possible to suppress achange in current such as undershoot or the like when the disturbance is generated,stabilize short circuit cycle, perform welding with a strong resistance to disturbance and asmall amount of sputter generation by changing an inductance value a plurality of timesduring the arc period.
