Abstract

PURPOSE: To prevent the production of adverse effect on the welded member due to shunt current, by providing the power supply unit converting the power of three- phase commercial frequency into single phase power in higher frequency than the commercial frequency, in said welder for ring shape welded member.
CONSTITUTION: In the unit in flush welding for the ring shape welded member 1, the power supply unit 6 is the inverter unit which converts the power in three- phase commercial frequency into single phase power in higher frequency than the commercial frequency, and the single phase output is connected to the primary winding 5a of the welding transformer 5. With said constitution, flush welding is made by applying power to the electrodes 2, 3. As a result, since the impedance of the circuit to which the branch current s flows can be increased, the shunt current can be decreased.
