Portable Diy Welding Equipment

Then a pair of complementary FETs is used for voltage amplification to generate a high-frequency signal. Finally, a step-up transformer is used to boost the voltage and an inductive AC is obtained on the secondary winding. Its power depends on the amplification ability of the amplifier circuit.Inverter welding machine uses IGBT tubes to form a single-ended forward converter circuit. The control system uses a pulse width modulation chip SG3525, which has a reverse conversion rate of 20 kHz and can perform constant-current external-characteristic control.
