Welding Inverter Control Circuit Diagram. Pic 1 - Homemade inverter welder welding inverter schematic - click to enlarge. The control circuit used in this scenario is UC3844 which is very much similar to UC3842 with pulse-width limit to 50 and working frequency to 42 kHz.
Due to high currents the current feedback uses Tr3 transformer. Secondary with a half of the core Tr1 with wound primary. PCB Drawings sprint layaut while drawing diagrams splan made with.
