Abstract

PURPOSE: To achieve better function and workability and reduce troubles and maintenance cost by reducing the size and weight of the remote control unit which controls the electric power necessary for welding by the fingers of welding in the engine drive DC welding machine.
CONSTITUTION: A single-phase mixed bridge rectifier 13 changes the AC from input 1 to DC and supplies the same to an exciting coil 6. By using the two SCRs 14a, 14b as the anode load terminal side rectifying elements of the rectifier 13, the pulses of the SCR gate pulse generator 12 controlled by a variable resistor 11 are applied between the gates and cathodes of the SCRs 14a, 14b. The conduction angles of the SCRs 14a, 14b are phase-controlled within a range of 30°W150° by the pulses of the foregoing generator 12, by which the current flowing in the coil 6 is controlled and the electric power to a welding output 9 is controlled by way of a welding power generator 5. This device is capable of changing the output 9 with good accuracy over a wide range only through the operation of the resistor 11 of the small and light remote control unit 3.
