Abstract
PURPOSE: To electrically control outputs at the short-circuiting by installing a short- circuiting time control circuit and an arc time control circuit which make control time and arc time control time short when welding current small, and making said control time long when the welding current increases.
CONSTITUTION: The output of a gate circuit 7 generates pulse PθO voltage. The pulse PθO sustain from an angle θO up to π. At the time of point B, it intersects with the point X1 on l1, and at the point of (θO+θS), the circuit 7 generates a firing pulse. This pulse connects from (θO+θS) up to π. At the time of a point F, it intersects at the point X3 on l1, and the circuit 7 generates a pulse connecting from the point of (θO-θA) up to π. Further, according to waveforms, the generation start point of the firing pulse of the circuit 7 changes with time (t), and at the time of output VP1, the angle of conduction of a thyristor is short. Next, at the time of output VP2, it is further longer, and at the time of output VP3, it is the longest.
