MB30 is special ized for power battery welding tags (Thickness of moer0.2-0.5mm need to be with Welding point and split.) It adopts MPU control system, air-drive with small dimension. It has protection circuit, alarm display, welding pre-heat wave, automatic lower voltage compensation when fluctuation of power supply voltage assuring stable output power and high welding quality. This machine is quite convenient for maintaining which can increase greatly its welding efficiency suitable for big volume mass producing line
