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. Len manship

    Cracking little machine so much lighter than my old one

  2. Len manship

    Cracking little machine so lite compered to my old one

  3. Mike Mac

    I have recently taken up welding and the struggle is real! This welder has helped me get on with some of the jobs around the place. It goes up to 160 amps but I have only used it up to 115 amps with 3.2mm rods. It worked great on my first few welds. The dial is very easy to use as it has a digital readout for exact amperage rather than an analog bar/twist mechanism. It is also amazingly light weight and therefore portable.

  4. james doherty

    prompt delivery,good quality of weld and very easy to get on to

  5. Mr David Evershed

    Just really good. Once I had current setting for size of rod and after welding together the 3rd Obelisk my welding technique had returned. I shall now move on to repairing the cover supports on the swing seat.

  6. James S

    First inverter welding but good quality and good service from Union mart after I required more assistance,

  7. Michael

    Very good welder easy to use and set for any job around your home/garage plenty of power to use with 2.5 or 3.2 rods it will easily weld 6mm thick material which I think is more than enough for DIY user

  8. Paul Makin

    This is a cracking little welder, it is easy to use just an on/off switch and an amp dial. it gives a good clean arc with little to no spatter. Only criticism is the leads could be longer but that can be said of every welding set.

  9. Piotr Krajewski

    This is a really strong welder. I did not expect :O

  10. Geoffrey S.

    This is my first inverter welder and it’s just fantastic to set up and use. Added bonus is the lightness of this one after lugging my old one around that weighed a ton.

  11. Lawrence Pettey

    Never used a welder before and it isn’t easy, but I managed to do a half decent job with this welder

  12. Aaron Haye

    Using weld now, easy and good use for my level of welding

  13. lyn parker

    Very easy to use, much better than my old Sealey stick welder

  14. gordon grear

    wow this welder is superb and very easy to use and very portable due to its light weight.

  15. Mike Robertson

    Have not picked up a stick welding machine for nearly 50 years. My how technology has advanced welding machines in that time! Easy to set – easy to use… only used with 2.4 E6013 so far but very pleased even on short runs. Should be okay for beginners the only need to master the technique of “stroking” the rod on the workpiece.

    Product itself is well put together and even experienced welders should be impressed… I spent first 10 years of my working life welding steelwork…. there are cheaper options but would really recommend the extra for this German product… good luck if you purchase 🙂

  16. A.Welder

    People can be a bit sniffy about arc welders but for general purpose hobby stuff it’s great. Cheap to buy, cheap consumables, it works on clean or rusty metal, indoors or outdoors. Ideal for sticking bits of metal together(!) and actually just as neat as a MIG (in my clumsy hands at least). New switch mode power supply makes it very light and easy to use. Impressed.

  17. Richard – Hitchin

    I had done a short course in welding so knew the basics. This is very easy to use but care needs to be taken on set up as the + and – of the cables could be clearer. Easy to dial down the power to stop splatter.

    I will be upgrading my rods for my next project as the cheaper sones are harder to re-ignite. I followed other peoples recommendations for the power supply. A shorter and higher quality extension lead will stop the house fuses blowing whilst working in the garage. I can’t fault the product. Would recommend 100%.

    Small, portable, heavy duty its there when you need it.
    I never welded in my life, watched few YT tutorials and bang! Job done.

  19. Paul Felgate

    Wanted a more modern machine but I’m only a hobby welder. I found this easy to set up easy to use and so much quieter than older models. Very good duty cycle so it doesn’t shut down after a couple of minutes and so far hasn’t tripped the circuit breakers, a good improvement. Hopefully it will last for years, will update as the months pass. Good unit for price.

  20. J Taylor

    Small – Light – Portable – Works of Mains. Bought it as I had a few odd welding jobs I needed to get done. This was cheaper than getting someone in to do them. I’m a ‘hobbyist’ welder and this Rohr 160 suits my needs. Had a broken hinge a ‘wrought iron’ steel gate. This welder made for an easy fix. Easy to strike an arc and got very good penetration and a clean weld. Was thinking of getting a MIG welder but opted for this ‘ARC’ (rod) welder and have no regrets. Very pleased.

  21. C. J. Dean

    Ordered for my son so he could weld his car exhaust – he’s a welder by trade and is very impressed with this unit –

  22. Keith

    Ordered late yesterday and UPS delivered to Yorkshire before 9 this morning. Brilliant service, good price so you have dug a happy customer out of a hole! Thanks

  23. Bernard

    Everything on this welder is just right. The quality of the attachments, such as clamps and leads, is outstanding, and the initial assembly of the product was straightforward.

    Using the welder exceeded expectations as working with it was easy. The welds turned out as expected, and the machine coped well during use, even for a novice like myself (our professional welder is full of praise).

    This welder is ideal for light use or DIY tasks, and we have no problem whatsoever in recommending this machine to potential buyers.

  24. Noel K Fletcher

    Great piece of kit, just what l needed for my workshop. Swift delivery, cost-effective, very satisfied. Thank you
