Electric welding machine
Application Notes
The working process of inverter welding and cutting equipment is to rectify and filter the three-phase or single-phase 50Hz industrial frequency alternating current to obtain a smoother direct current, and the inverter circuit composed of IGBT or field-effect tube will change the direct current to 15-100kHz alternating current, and after the medium frequency main transformer step-down, rectify and filter again to obtain a smooth direct current output welding current (or again inverted output alternating current of the required frequency). ). The control circuit of the inverter welding and cutting equipment is composed of a feeder circuit and a driver circuit, which process the voltage and current signals back to realize the cycle control of the whole machine, using pulse width modulation PWM as the core control technology, so as to obtain fast pulse width modulation of constant current characteristics and excellent welding and cutting process results.
