Abstract
PURPOSE: Output-current-corresponding-voltage is detected and compared with standard signal to produce current limiting signal. The signal is treated by oscillator and logic circuit to control output current, providing reasonable current for flush welding.
CONSTITUTION: Current signal 18a of terminal 17-1 to transformer 4 wire 4a current is fed from current transformer 18a to detector 19 and formed into comparison signal 19a which is fed to comparator 20. When the signal 19 becomes equal to standard signal 20a, the comparator 20 transmits current limiting signal 20b to oscillator 21. Based on standard signal 11a, the oscillator 21 sends frequency signal 21a to logic circuit 22. The logic circuit 22 having binary circuit transmits pulse signal 22a to pulse generator 23, which produces gate pulse 23 that triggers thyristors 14-1 to 14-8, so that output current is controlled within a specific range, setting inverter current capacity to proper value for flush welding.
