1.NBC DIGITAL SERIES WELDING MACHINE APPLICATION AND FEATURE
NBC digital series inverter gas shielded welding machine (NBC-350III, NBC-500III, NBC-630III)
is a kind of gas shielded welding high performance for semi-automatic welding digital control
welding machine, it could be doing the welding work with 0.8-1.6mm welding wire and 1.2-1.6
tubular welding wire, which are for low carbon steel and low alloy steel section. This series of
welding machine has reasonable external static and dynamic characteristics, and compared with
preceding NBC-II series welding machine, it has the following new functions and features:
Better appearance of weld, lower possibility of deformation;
Higher success rate of arc starting due to the application of lean control method;
Digital control panel, providing a friendly man-machine interface, and convenience of operation;
One-knob intelligent control system;
Spot welding;
Capability of storing 10 suites of diameter specifications;
Higher stability of power supply to wire feeder circuit.
