Abstract
PURPOSE: To prevent the fluctuation in arc length occuring in hand shaking and maintain a globule shift state correctly by providing a circuit which detects the change in base voltage and controlls the feed speed of a wire during welding.
CONSTITUTION: Target base voltage is inputted to a comparator 103 by a base voltage command circuit 105. When th arc is generated, base voltage is detected with a base voltage generating circuit 101 and the detected voltage is inputted to a comparator 103, where it is compared with the target base voltage. The differential voltage thereof is inputted to a wire feed setting circuit 15 which changes the feed speed of a wire in such a way that the output of the circuit 105 equals to the base voltage. On the other hand, pulse frequency is controlled by way of a pulse peak current setting circuit 114. The correction of arc length is accomplished quickly by this controlling of the feed speed of the wire.
