Mr Dillon's review on his Röhr Welder

"Arrived in Ireland from the UK in 3 working days, so fast that amazon said it was still in transit 2 days after I received it. i haven't welded in 20 years but I knew after 20 seconds this little welder was pure quality and I am in fact going to do a YouTube video promoting it as I couldn't find one, haven't tried the tig yet as I'm waiting on gas but the arc is so smooth and clear on stick I know the tig will be fine, very nice tig set too I might add... If I was to find a fault I would say The rod holder is a little finacky but perfectly functional"




RÖHR MMA-250FI IGBT MMA Welder

--

Introducing the RÖHR MMA-250FI IGBT MMA welding machine. Using the latest Inverter technology to dramatically reduce overall footprint, as well as IGBT monotubing to significantly increase efficiency compared to normal MOS tubing.

As well as size, Inverters dramatically reduce the power required to weld, increasing efficiency by 30%, whilst producing a constant power supply for a more stable welding arc.

The power source offered by this machine is stronger, more concentrated and produces a more stable arc. Its response is quicker and it can even be adjusted for specialty welding to make the arc softer or harder.

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 color 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.

Key Features:

  • For repair and maintenance work indoors and outdoors
  • Suitable for stick/electrode welding (MMA welding)
  • Body made of powder coated steel sheet
  • Compact and robust construction
  • Hot-start function facilitates ignition of the arc
  • Mobile use

    TIPS & ADVICE

    Choosing the correct Welder:

    Röhr Welders offer everyday solutions for a variety of welding needs. Choosing is easy with our guides and product details.

    Material:

    Different materials require a certain type of weld. Some of our machines will do it all whilst others specialise

    Amp Output:

    Materials and thickness define the amount of power you require. As a rule of thumb, the higher the better

    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 Uses

    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


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




    Suitable For:
    • Steels (non-Alloy)
    • High Strength Joins
    • Aluminium & Other Steels

    MMA (ARC/SMAW) - Manual Metal Arc


    Traditional welding technique using a flux core.

    Simple vs alternatives, quick to learn




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

    IGBT - Insulated Gate Bi-polar Transistor


    Most recent technology using capacitors

    Stores high voltages for steady release




    Advantages:
    • Multi Purpose TIG/MIG
    • Micro Controlled Current
    • Highly Efficient

    Inverter - Alters Input Power for Desired Use


    Micro controller Management

    Rectifies AC to DC



    Advantages:
    • Controllable Output 0-100%
    • Lower Power Consumption
    • Highly Portable

    Choosing the correct welding machine can be a daunting process. The task in hand should define the product you require but also consider additional uses which you may encounter in the future. More capable machines offer greater flexibility with materials and offer more control whilst a more basic welder will produce the desired results for a known task.


    Please note the welding machines are not supplied with consumable components such as wire or gas.
