Abstract
PURPOSE: To eliminate unstable phenomena owing to fluctuations in arc length and to perform adequate welding by detecting base voltage and determining the differential voltage from a target value thereby changing pulse peak current in a manner as to eliminate the differential voltage and maintaining the base voltage at a prescribed value.
CONSTITUTION: When the arc is generated upon starting of welding, the base voltage in the arc is detected by a base voltage detecting circuit 101, and is coneucted to a comparator 103, where it is compared with the target base voltage of a base votage command circuit 105. The differential value thereof is inputted to a pulse width setting circuit 113, by which the pulse width is changed by the circuit 112 in such a manner that the output of the circuit 105 and the base voltage in the arc are made equal, whereby the base voltage is controlled so as to be kept at a prescribed value at all times and the unstable phenomena accompanied with the fluctuation in the arc length occuring in hand shaking are eliminated.
