n Figure 9-14. The machine no-load output voltage of 45V DC, 90V (peak), the short-circuit current of 125A DC. Circuit consists of five parts: Power section (by the diode VD16 ~ VD2 [filter capacitor C7 etc.), the inverter section points (by the diode VDi ~ VD4, SCR Vl-V4, resistor Ri-R4, capacitors and inductors Li CL, etc. composition), touch -flop (by a pulse transformer TMi, TMz and associated RC components, diodes, regulator etc.), an output unit divided (by the transformer T and the diode VD22 ~ VD25 etc.) and arc suppression circuitry (by the Triac V5, thyristor V5, the regulator VS3, diode VD, 6, capacitor C8, resistor R14 ~ Rl7 etc.).
