Claim Text:
1. An arc sensor control system for arc welding for obtaining satisfactory beads in a groove of a workpiece that is a welding target, the arc sensor control system comprising: an actuator configured to cause a welding torch to track a weld line of the workpiece by causing the welding torch to move in a direction of the weld line of the workpiece at a specified torch height while causing the welding torch to move in a cyclic manner in a width direction of the groove of the workpiece with a specified weaving width; a sensor configured to detect a welding current or an arc voltage; a calculation unit configured to a control unit configured to control the weaving width and the torch height based on the manipulated variable regarding the weaving width and the manipulated variable regarding the torch height, wherein: each of the first and second ratios is set so as to increase as the groove angle increases.
