The CRUXWELD ARC251iS is a portable 250 A inverter welding machine for MMA (stick) welding that runs on both a 230 V single-phase supply and a 415 V two-phase or three-phase supply. Set current, Hot Start and Arc Force with one knob, read them on the digital display, and switch on VRD for safer site work.

The ARC251iS is a 250A inverter welding machine that gives smooth DC welding power for most metals: alloyed and non-alloyed steel, stainless steel and cast iron.
Its IGBT inverter uses less energy than an old transformer welder, works with any type of electrode, and sits in a rigid, IP-rated dustproof case with the control panel protected against accidental knocks.

From thin sheet with 1.6 mm rods up to 3.2 mm rods at full speed and 4 mm on intermittent work.
Runs on 230 V single phase, or on 415 V two-phase and three-phase. One machine for the workshop and the site.
Lowers the open-circuit voltage at the holder whenever no arc is burning.
Outstanding arc stability with basic and acid electrodes, plus anti-stick.
One display, eight indicator lamps and one push-and-turn knob. The red-marked controls set the weld.
12345678910Three functions that make stick welding easier for every welder, new or experienced.
A short burst of extra current at the moment of strike heats the rod tip, so the arc lights first time, even with basic electrodes.
When the arc gets too short, the machine adds current to keep it burning. Useful for vertical, overhead and root runs.
If the rod sticks to the plate, the current drops at once, so it breaks free without overheating the holder or the rod.
The Voltage Reduction Device keeps the voltage at the electrode holder low while no arc is burning, and restores full power the moment the rod touches the work.
Works with basic and acid electrodes. Typical current ranges for mild steel rods:
| Electrode | Typical current | On the 10–250 A range |
|---|---|---|
| 1.6 mm | 30–60 A | |
| 2.5 mm | 60–100 A | |
| 3.2 mm | 90–140 A | |
| 4.0 mm | 130–180 A (intermittent) |
Typical values. Follow the electrode maker’s range and fine-tune with Arc Force for position welding.




A compact inverter with a top handle that runs from a 230 V single-phase socket, a 415 V two-phase or three-phase line, or a generator.
Automatic Hot Start and reliable arc ignition cut wasted time and rework.
VRD lowers the voltage at the holder between welds for damp, confined or elevated work.
Automatic compensation for mains fluctuations within ±20%, with overheat and overcurrent protection.
