NBC series of IGBT inverter CO2/MAG welding machine
Features:
1.Advanced soft switch inverter technique can solve the IGBT easily broken problem.2.Set soft or hard of arc freely by waveform control knob, achieve the best act state according to the realistic
requirement.3.No melting ball on the welding wire port after welding, high success rate of striking arc.4.Large adjustable range of welding parameters,easy to operate, particularly suitable for small current vertical position welding and overhead position welding.5.High power factor, low need of electricity, small size and weight, easy to move.6.NBC 500 has common and industry two types for customer’s selection.NBC 500 and NBC 630 also have the functions of CO2 welding, manual welding, carbon arc air gouging.7.This machine is suitable for terrible environment and field work.
