The power board (13) control section oversee the manage-
ment of all power source functions, including:
− the boost converter enabling;
− welding current regulation, by the inverter;
− welding system control panel.
In the front panel (par. 2.4) are collected leds for signalling
and potentiometer for welding current setting.
The power board (13) control circuit receives the
temperature signal from the NTC sensor, located on the
inverter igbt external dissipater connected on J13 terminals
on power board (13).
The power source output terminals are located on the front
panel (GIFAS attack D and E).
