ウン制御装置。In a slope-down control device for a welding device that controls a welding electrode to have an arc length corresponding to a set voltage, the slope-down control device includes a first setting means for outputting a first set voltage that determines an arc length when welding is performed, and a first setting means that outputs a first set voltage that determines an arc length when welding is performed; Until execution, a second setting means outputs a second setting voltage that decreases from the initial value with the passage of time and whose initial value is variable according to the welding conditions; In addition, a voltage output means for outputting a third set voltage is provided.
A slope-down control device characterized in that the arc length is controlled by a set voltage and the arc length is gradually decreased from an initial value at the time of startup.
