Röhr MMA Welder – MMA-200FI-07


(5 reviews)

The advanced MMA-200FI welder from Röhr is easy to use, and perfect for beginners and professionals alike.

Featuring the latest Inverter technology, this unit dramatically reduces the overall footprint and increases efficiency by 30% whilst producing a constant power supply for a more stable welding arc.

The power source offered by this machine is stronger and more concentrated. Its response is quicker and it can even be adjusted for speciality welding to make the arc softer or harder. As well as that, it also includes IGBT mono tubing to significantly increase efficiency compared to normal MOS tubing.

This kind of welding machine has the following characteristics: effective, power saving, compact, stable arc, good welding pool, high no-load voltage, high capacity of force compensation and multi-use.

It can weld stainless steel, alloy steel, carbon steel, copper and other colour metal. It can apply to electrodes of different specifications and materials, including acidity and fibre. It can operate at high altitude, the open air and inside and outside environments. It is compact in volume, light in weight, easy to install and operate.

Whether it’s aluminium bike frames or reviving your passion for steel sculpture, there’s a Röhr for the job and a Röhr for you!

With guaranteed expert support from Röhr qualified staff, you can purchase with confidence knowing that we’re here for you if you have any questions.

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.


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

  1. Ian Michael Miles

    Just started playing with my new toy, the MMA-200Fl-07.

    Firstly delivery was super fast.

    After the obligatory read of the instruction manual (Just to be on the safe side) she was plugged in for a test run. Welding was so easy with this unit. I welded some 6 mm thick box section and it was so easy.

    Highly recommend this company and welder.

  2. John Trigell

    Super quick delivery, this was substantially cheaper than anywhere else i searched. very pleased with product and service.

  3. Chris Kennedy

    A fantastic portable welding machine with an amperage range to cover the majority of welding. Adequate instructions but could advise on the amperage settings for different materials and/or thicknesses but this info is easily obtainable on the net.

  4. Keith Lonsdale

    Great welder, welds 6mm plate with 4mm rod


    Excellent piece of kit ..Perfect for the job in hand..Welds really nicely.
