NBC- series inverter CO2 welding machine is a kind of general semi-automatic high performance welding machine with CO2 as protective gas. Solid cored and flux-cored welding wires of diameter between 1.0mm and 1.6mm can be used to weld low carbon steel and low alloy steel components. Inverter welding machine of this type has proper static external characteristics and excellent dynamic properties, whose features are as follows:
● Inverster technology can guarantee highly stable welding voltage under the condition of voltage fluctuation of power grid and the changing arc length. Electric arc has strong self-regulating abilities and stable welding process can be obtained.
● Welding spatter is lower and metallic deposition efficiency is higher.
● It has good weld formation and little weld deformation.
● Adapt the method of strong pulse arc ignition with high successful rate of striking arc.
● It can eliminate balls while arc extinguishing and improve the next striking performance.
● Auto-lock function can reduce labor intensity of welding machines while handling with large and long welding.
● High performance power system is used in wire feeding circuit and smooth wire delivery is realized.
● It is small and light and easy to be carried about.
● It takes advantages of energy-saving, lower cost and requirements of power grids capacity.
● Owing to digital processing and adjustments of practical welding parameters and setting parameters are done by monitoring-system, any welding machine of NBC series is capable of welding the steel as thick as 0.8mm using welding wire with diameter of 0.8-1.6mm.
