CEBORA S.p.A.
Micropanel board (70) contains the power source main microprocessor. More
specifically, it communicates via the CAN-BUS with microinverter board (37), motor
control board (222) and panel board (212)
Microinverter board (37) regulates the welding current, generating a PWM signal to
send to the inverter driver circuits, and communicates with micropanel board (70) to
manage the welding system.
Control board (37) receives temperature signals from NTC sensors positioned on the
heatsink near the IGBT module on power board (48) to measure the inverter
temperature and near DIODE assembly (27) to measure diode output temperature.
An output voltage signal is taken from power source output terminals (+)N and (–)L.
This is used by control board (37) to adapt generated performance based on welding
arc conditions in the various possible types of welding. Output terminal (+)K is
connected in parallel to terminal (+)N. It is used in specific welding modes (see
instruction manual).
Earth dispersion sensor (10) on the power source protects the YELLOW-GREEN
cable of the mains cable from any current dispersed to earth greater than 15A.
