特徴とするアーク長制御装置。 TIG welding involves generating an arc between a tungsten electrode and the workpiece, and welding the workpiece while adding a filler rod.The welding torch is moved up and down to keep the arc voltage constant and the arc length constant. In the arc length control device, there is a circuit that stores the arc voltage that is the reference for control, a manual switch that moves the welding torch up and down, and an arc length control effective period immediately after the welding torch is moved up and down using the manual switch. 1. An arc length control device comprising: a timing circuit for re-memorizing the arc voltage at as a reference voltage for control.
