Product info:
NB-350/400/500 (A161-series) is a whole digital semi-automatic gas shielded
metal-arc welding machine based on the technologies of DSP, fuzzy control, wave
control and adaptive control, which consist of power source and wire feeder. The machine
has the characteristics of stable welding process, low spatter and good weld. The molten
pool is easy to be controlled, operation is simple to be done, and efficiency is high.
Main Functions:
IGBT inverter
High reliability and excellent welding performance
Wide range of supply voltage
Visual and easy to operate
Synergic adjustment
Energy saving and small volume
