The Stealth Digi-MIG 250-1 is a single-phase MIG/MAG inverter delivering 50–250A with up to 100% duty cycle at 200A, ideal for welding carbon steel, stainless steel, alloy steel, aluminium and flux-cored applications.
The Stealth Digi-MIG 250-1 is a digitally controlled inverter welder designed for professional performance in a compact, lightweight build.
Using advanced IGBT inverter and PWM technology, it delivers stable arc characteristics, high efficiency and low power consumption compared to traditional transformer machines.
This multi-function MIG/MAG power source supports manual and synergic modes, with waveform control to ensure a smooth, stable arc across all welding positions.
It is suitable for a wide range of metals including stainless steel, carbon steel, alloy steel, aluminium and flux-cored wires. Built-in safety features protect against over-voltage, over-current and overheating, while an intuitive digital display provides real-time welding parameters.
With a rated duty cycle of 60% at 250A and 100% at 200A, the Digi-MIG 250-1 offers reliability and performance for fabrication, automotive repair, pipework, maintenance and DIY applications.
Includes a 4 rolls wire feeder, burnback control, M25-3 torch, and 2068 regulator for added convenience.
