Mitech NB250 MIG Welder


Mitech’s NB250 offers infinite voltage and wire speed control for optimum control of welding parameters. Latest IGBT Inverter technology also means this machine is lighter and more portable than a transformer based machine, delivering higher duty cycles at higher amperages compared to conventional MIG power sources.

The NB250 is designed as a general purpose MIG / MMA welding machine and is suitable for a wide range of operations including Solid Wires, Flux-Cored Gas Sheilded & Gasless wires up to 1.2mm Inductance setting offers finer control of the arc characteristics, crater current adjustments giving the operator the control for perfectly finished welds. MMA function for stick welding as well as an Arc force adjustment for a more refined stable arc. Euro torch connection allows easy connection and removal of the torch. Thermal and voltage overload protection. Low noise fans for quiet and smooth operation. The NB250 is suitable for various applications including General Engineering, Heavy Industrial, Repair and Maintenance Work, and Agricultural etc.
