The MIG-250MI Gives you Röhr Quality

Exceed your Expectations

Röhr welders are built to last with high quality components that will ensure reliability for occasional or regular users. This welder uses the latest inverter technologies. Inverters dramatically reduce the power required to weld by increasing efficiency by 30% and they produce a consistent power supply giving you the most stable welding arc. IGBT monotubing significantly increases efficiency compared to normal MOS tubing.

Perfect for a Wide Variety of Welding

ontrol electric short transition and blending transition. This provides stable wire speed, low power consumption and no electromagnetic noise. This welder is multi-use so you can weld low-carbon steel, stainless steel and alloys.

Dual "2-in-1" Portable Functionality

This welder can be used for MMA Arc welding or MIG / MAG welding and it's highly portable due to it's lightweight design. The unit produces neat welds that leave you in no doubt that this high quality welder is designed by Röhr.

The Latest IGBT Technology


IGBT is a bipolar transistor with an insulated gate electrode. This semi-conducting device is being increasingly used in power electronics because it combines the advantages of two transistor types: the easy controls of the field effect transistor and the fast switching and high breakdown voltage of the bipolar transistor. The IGBT also offers some robustness against short circuits because it limits the electrical continuity.

Featuring ARC Force and Hot Start


With ARC Force, the current increases automatically when the arc is shorter. Hot Start automatically boosts the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.

MMA Arc Welding


MMA is electrode welding with a coated electrode.



This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.

Flexible Welding and Stepless Feed


This unit features a stepless wire feed system so you can focus all of your attention on your weld. Also it's highly portable design allows for use wherever you need it.

MIG / MAG Welding


MIG is used for welding materials such as magnesium, copper and other non-ferrous materials and their alloys. MAG on the other hand, is suitable for steel, structural steel and most of its alloys. Thus, great welding seams can be briskly and efficiently manufactured with different thicknesses, ensuring that material distortion is kept to a minimum.

Vari-gas Flow


MIG/MAG welding require a protective gas. Inert gases, such as argon and helium, as well as active gases (for example carbon dioxide) and other mixtures can be used. The solenoid valve regulates the flow of gas. The valve is operated via a button on the torch.

Standard UK 3 Pin 240V AC


This welder does not need a specialist power supply, it can run straight off the mains.

Very good quality.
The weight is not indicated in the description: 15.2 kg the MIG alone. 17.3kg with cables and lance. Don't forget to order cored wire (or coreless wire if you are using gas). This is my first MIG, so I don't have a lot of experience in other positions. Very well finished product. It just lacked a screw + washer to fix the wire drive roller. But I used the station to weld 2 washers and a screw! It's perfect ! I ordered ENI cored wire. and for the moment I find that the soldering is good, I have not yet invested in a gas cylinder.
