TIG and MMA Welding

TIG is a welding method in which the arc is maintained through an electrical current supplied from a non-consumable electrode. The arc is protected from the access of air by an inert gas. MMA is electrode welding with a coated electrode.

2-Stroke and 4-Stroke

2-Stroke : start the weld by placing pressure on the torch button. Stop the process by releasing the button.

4-Stroke: by pressing the torch button the solenoid valve opens. allowing the gas to flow in. The gas pre-flow ignites the arc at the pre-set current. Releasing the burner button initiates a rise in the current to that of the pre-set welding current. The welding process stops once you press the burner button again.

The Latest MOSFET Technology

The MOSFET transistor helps to provide the highest standard of performance combined with a compact and lightweight design. The result is 85% efficiency! The welding current is very stable and thus ensures a perfect weld every time.

  1. john

    i after say it as good as my mig. ones you find the correct welding rods. its a jem as i have a lot of rods to pick from
    as for the tig you will after fork out 60 for purer argon
    and 64 deposit .take the bottle back you get 54 back or buy
    again. you can buy oby yellow bottles you need the hose and clips
    and a Gage. and a good mask.
    ask unionmart they will help you out. i would think the welder will last

    Purchased other TIG Welder in the past and didn’t do the job and had to send it back. Purchased one from you and it works great on all metals . Very pleased with purchase.

  3. Chris Drake

    Essentially been looking at a TIG for a long time but never made the jump as I’ve got gas, MIG, stick & scratch TIG (okayish but…).

    Decided to bite the bullet and was attracted by this model and I haven’t been disappointed.

    The first job I needed it for was welding a new piece into my track bike exhaust system as the stainless steel in part had come of age or sadly died. Got a piece of .9mm SS of the right grade. The correct filler rods and electrodes and hey presto, job done.

    I’ve since done other small and delicate jobs and haven’t looked back.

    The only thing wrong with it is that I didn’t own it years ago.

    If you’re looking for a TIG I don’t think you can go far wrong with this beast.

    One tip if you’re looking for Argon then Hobbyweld is £117 or a new bottle £52 for a refill and no annual fee.

    Happy welding and thanks for a great product Union Mart 😉

    Great bit of kit!

  5. MikesMGC

    I am using this welder to do some repairs on an MGC project and also to make a car rotisserie where I will use the electrode stick welder side of the Rohr. I used it today to start on the car rotisserie using 50x50x3mm steel box and it worked very well. Plenty of power and easy to use machine which I am looking forward to use more often over the coming months.

  6. M J

    Fantastic machine and very easy to set up.

    Produces very nice welds


  7. Tony R

    I’m a novice welder and after some research I went for this one.

    It arrived early, very well packaged and in pristine condition. The quality of engineering is great and for a novice, it is easy to use.

    I had a few initial questions and contacted the supplier directly. They responded very quickly and answered all of my questions well.

    I really like this equipment and am looking forward to using it more to improve my welding.

  8. cameron

    Very sturdy bit of kit
