摘要： A control method of arc welding in which positional control of an electrode or a torch is performed while regulating the welding conditions based on optical information obtained from arc light emitted at the time of arc welding. The optical information obtained from arc light, i.e. illuminance, has a specific correlation with the arc length or the torch height and welding control is performed based on the illuminance. The control method has a step for comparing the illuminance with reference information based on the correlation, and a step for regulating the welding conditions based on the comparison results.
