6. ELECTRICAL SCHEMATICS
1 - Single phase mains input, rectifier and condenser.
2 - Transisters and drivers switching bridge (IGBT). Converts rectified mains into high frequency (40kHz) AC and permits power regulation according to the
current/voltage requirement of the weld.
3 - High frequency transformer adapts voltage and current to the values required and also isolates the mains from the welding circuit.
4 - Secondary rectifier bridge with inductance which changes the AC into a continuous current with a low wave-length.
5 - Electronics, which compare the value of the welding current against that selected by the operator and modulates it via the IGBT drivers. Also includes the
safety system.
