Abstract: An arc welding system includes a feeder to feed a consumable electrode to a welding torch. A power source supplies power to between the electrode and an object. A welding controller controls the feeder and the power source to cause a short-circuit state and an arc state to repeat between the electrode and the object. A robot moves the welding torch along a welding line. A robot controller controls the robot. A detector detects whether a state between the electrode and the object is the short-circuit state or the arc state. A determiner determines whether a first period or a second period has elapsed since the detector detected the arc state. An instructor instructs the robot controller to decelerate the welding torch when the determiner determines that the first period has elapsed, and to stop the welding torch when the determiner determines that the second period has elapsed.

Abstract: A power supply device for arc welding according to an embodiment includes a constrained short-circuit opening unit and a reexecuting unit. The constrained short-circuit opening unit reduces, when a change amount of a welding voltage becomes not less than a predetermined threshold while raising a welding current between a consumable electrode and a workpiece, the welding current for a predetermined time interval to execute a constrained short-circuit opening process for opening the short-circuit state. The reexecuting unit makes the constrained short-circuit opening unit reexecute the constrained short-circuit opening process after the constrained short-circuit opening process is executed.
