A welding generator comprising an input rectifier stage, a bank of leveling capacitors, an inverter block, a transformer, a rectifier stage and an inductor downstream of which the arc forms and an input voltage adapting regulator stage having , in series at the output of the input rectifier, a first controlled electronic switch with in output a first diode also connected to the common line, an inductor, a second controlled electronic switch and a second diode being connected in series downstream of the first controlled electronic switch, the output of the inductor being connected to the common line, the second diode being connected to the bank of leveling capacitors; the voltage Vin measured at the output of the rectifier stage having thus the same orientation as the voltage V0 measured across the bank of leveling capacitors.
