Example Embodiment
[0022] The working principle of the embodiment of the drawn arc capacitor energy storage stud welding machine of the present invention is as follows Figure 1 to Figure 4 Shown.
[0023] The 220V power supply is connected to the transformers T1 and T2 after the switch K1 and the total fuse F1 in series. T1 is the working transformer, and T2 is the control power transformer. T1 turns 220V power into AC190V charging power and AC60V arc power supply. Transformer T2 provides control power to MCU (MCU model is PIC18F6420) control board and main control board. The charging voltage range is 40V-200V.
[0024] The main welding circuit includes charging rectifier bridge D2, charging thyristor (bidirectional thyristor) D1, energy storage capacitor (capacitor bank) C2, discharging thyristor D6 and absorption diode D5. Compensation capacitor C1, charging thyristor (bidirectional thyristor) D1, charging rectifier bridge D2 with 1 and 3 terminals connected in series to the two ends of the AC190V...
