Abstract

PURPOSE: To stabilize the arcing voltage on purpose to prevent the inadequate feed of the electrode, by controlling the fluctuation of the feeding speed of the welding electrode so as to be maximum at or nearby the required set value for the arcing voltage, and by controlling the fluctuation of the feeding speed of the electrode to be mild for other range of arcing voltage.
CONSTITUTION: At feeding such welding electrode as the covered electrode, etc., the feeding speed Vw is made proportional to the arcing voltage Va for the period from zero to Va1 which is near the set voltage Vs, as shown by the straight line I. In the period that the arcing voltage is larger than Va1 and is near the set voltage Vs, the feeding speed is given with a characteristic shown by the greatly inclined straight line II; and for larger arcing voltage, the feeding speed is maintained approximately constant as shown by the line III. According to this feed control, the response becomes rapid in the neighborhood of the set voltage Vs, and the arcing voltage Va is stably held at the set voltage Vs. As a result, if the arcing voltage Va excessively drops down depending on some reason, the feed of the welding wire (rod) does not stop, so that the inadequate feed is hardly carried out
