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.

Anti-Stick

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

Choosing a Welder

Choosing the Correct Welder

Choosing the correct welding machine can be a daunting process. Our handy guide below explains some of the
terminology and different types of welders that we stock. This will help you to select the correct product that will be
fit for purpose for your specific welding tasks.

MMA (ARC/SMAW) – MANUAL METAL ARC

MMA (ARC/SMAW) – MANUAL METAL ARC

Traditional welding technique using a flux core. Simpler than other kinds of welding and quick to learn.

Suitable For:

  • Steels (non-Alloy)
  • Iron
  • Can be used for Aluminium, Copper etc

MIG (GMAW) – METAL INERT GAS

MIG (GMAW) – METAL INERT GAS

Uses an inert gas shroud around a continuously-fed reel filament to melt and join surfaces. Faster than TIG, suitable for most welding applications

Suitable For:

  • Aluminium
  • Steel/Stainless
  • Most welding applications

TIG (GTAW) – TUNGSTEN INERT GAS

TIG (GTAW) – TUNGSTEN INERT GAS

Uses a tungsten filament rod with inert gas shroud to melt and join surfaces. Produces a strong and higher quality weld than MIG.

Suitable For:

  • Stainless Steel
  • Thinner Metals
  • Fine Joinery

MAG (GMAW) – METAL ACTIVE GAS

MAG (GMAW) – METAL ACTIVE GAS

Reacts with the weld to produce less spatter or burn-in.

Suitable For:

  • Stainless Steel
  • High Strength Joins
  • Aluminium & Other Steels

IGBT – INSULATED GATE BI-POLAR TRANSISTOR

IGBT – INSULATED GATE BI-POLAR TRANSISTOR

Most recent technology using capacitors. Stores high voltages for steady release

Suitable For:

  • Multi Purpose TIG/MIG
  • Micor Controlled Current
  • Highly Efficient

5 reviews for Röhr MMA Welder – MMA-250FI-08

  1. P sopjes

    Very good welder the machine not me very compact and light very happy with it 

  2. Patrick Nolan

    Just got the welder today as a replacement for my 20yr old kit. I know technology has moved on but I didn’t expect it to be this good. Even with my ancient electrodes it worked smooth and well. I will get new rods so it should be even better!

  3. Ramon

    This product is great and definitely what i’ve been looking for. It’s simple enough to use and does the job well. Portable and powerful.

  4. Euan Seel

    I think this is a very good portable welder, it is very adjustable, I am no welder, but even I can use it and get results.

    Very compact and lightweight, making it very easy to move about.

    Great piece of kit, and very promptly delivered.

  5. Jonathan Mosse

    This is a first class welder, more than powerful enough to weld 12mm mild steel, with power in reserve. Although it specifies a 60% duty cycle it has yet to stop while I’ve been working on the 250 amp full power setting. Incidentally, the claimed duty cycle at 190 amps is 100% which is more than believable based on my experience to date, so no more waiting an age for a transformer to cool down whilst desperate to continue with a job!

    It plugs into the standard 13 amp plug and is featherlight to carry. Indeed when the courier handed me the box I thought Union Mart had forgotten to pack the welder. It’s stylish too!

    Welcome to stick welding 2019!
