Abstract
PURPOSE: To make possible use in a wide current region range by providing two thyristors connected at the same polarity side in series between both terminals of a transformer for arc welder and two sets of rectifier circuits consisting of reactors and diodes in parallel with these and providing a welding load between the points of their connections.
CONSTITUTION: The circuit connecting thyristors 2a, 2b on the same polarity side is disposed in series between both output terminals A, A' of a power transformer 1 for arc welder. The series circuit of reactors 4a, 4b and diodes 3a, 3b wound on the same core is connected in parallel with this circuit. A welding load 5 is placed on the circuit connecting the contacts of the thyristors 2a, 2b and the contacts of the reactors 4a, 4b. At the alternate current supplying of the thyristors 2a, 2b, the magnetic flux directions generated in the same cores of the reactors 4a, 4b become the same, thus direct welding current may be flowed in the current of a wide range to the welding load 5.
