NBC 630
Features:
It adopts current-type PWM control and full-bridge inverter circuit, which effectively controls the instantaneous current of IGBT and improves the reliability of the machine.
ZVS of leading bridge and ZCS of lagging bridge can be achieved by adopting soft switching mode and limited bipolar soft-switching inverter.
2T/4T function is available, which facilitates longtime welding.
Welding voltage and welding current are presettable and displayable.
Crater voltage and crater current are adjustable.
Electronic reactor control brings stable welding, little spatter, deep penetration and good shaping.
he duty cycle reaches up to 100% under rated output of 630A/44V.
