Industrial Water-Cooled MIG/MAG Welder System

This system is built for the toughest environments.
The Morrow NBC Series is a water-cooled system. It comes with our high-precision MIG power source and a patented vortex-pump cooling unit. It is made for heavy industries like boiler manufacturing, shipbuilding, and steel structures. With this system, the arc stays stable and the torch stays cool, even when the temperature hits 50°C. It also works well with different voltages, so power grid changes do not affect it.

Features

■ Adopt the soft switch technology, high efficiency, low power consumption

■ Automatic protection from overcurrent, overheat, over/under voltage

■ Support digital display and presetting of current and voltage, wide adjustment range of voltage

■ Particular function of automatically removing melting-ball from the end of the welding wire

■ Adopt the closed-loop system to control arc and waveform control system to adjust the arc force

■ Suitable for low carbon steel and low alloy carbon with solid/flux-cored welding wires of different

specifications

■ Widely used in such areas as automobile, shipbuilding, bridge, petrol chemistry and construction,

and so on

■ A voltage fluctuation of ±20% is allowable

■ Small size, light weight

■ Support frequent welding, little spatter, high efficiency in melting metals

■ Support MIG welding, MMA welding
