ク長を制御する制御手段とを設けたことを特徴と
するアーク長制御装置。 An arc length control device that keeps the arc length constant by raising and lowering the torch so that the arc voltage or arc current falls within a set range includes a detection means for detecting a change in welding conditions, and a detection means for detecting a change in welding conditions, and a detection means for detecting a change in the welding conditions, The arc length is characterized by being provided with a drive means for stopping the elevation until the change in the welding conditions is completed, and a control means for controlling the arc length using the arc voltage or arc current at the time when the change in the welding conditions is completed as a reference value. Control device.
