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.

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.

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.

    One Year Update

    Its over a year since I purchased my HP200PP and the verdict is in. Its a great welder, during lockdown I decided to give it a real test. The tailgate on my 1984 MK2 Fiesta was showing a little rust around the window so out the window came revealing little left of the lower flanges and other rust holes. I decided not to use my MIG welder at all and TIG where ever I could. To say the least it was a steep learning curve and my first welds were not pretty but after hours of welding thin rusty metal I was producing some reasonable results. I was able to butt weld metal 1mm thick and even fill pin holes using a copper heat sink. The pulse weld facility is handy when heat builds up too quickly. The machine has done loads of other jobs in addition to the car repairs and continues to perform flawlessly.
    “Good Points”
    The HF start is amazing. The torch provided performed well. The machine worked flawlessly. Current control easy. Its very light weight. Torch hose/cable very long. It TIG welds up to 6mm steel. Ive learnt to weld stainless steel. The machine is excellent value for money. Customer Service Excellent.
    “Poor Points” The provided mask flimsy and no use if TIG welding. Post flow gas pretty useless as arc continues with post flow gas and cant be adjusted independently. I highly recommend this machine and Union Mart to anyone.

    Quería una maquina capaz de soldar Tig a buen precio y ha sido un acierto.
    Mucha calidad en los materiales y grandes soldaduras

    The service from Union mart is second to none ordered 13.00 Monday was delivered by 0805 am Wednesday by dpd and the quality is of the highest quality although I only purchased one of the cheaper models and it is top quality

    Just had my new HP-200PP delivered straight out of the box really easy to set up and first job done and finished. Lovely run produced by the MMA not tried the TIG yet but looking at the quality it should be first class.
    I teach welding and would be quite happy to use this machine with my learners.

  5. Nick

    Needed to weld some stainless up and have always wanted to try TIG so that was the only excuse I needed to buy a new tool lol.

    I knew it wouldn’t get used very often so wasn’t prepared to have £500+ sitting in the corner of the garage.

    Did my research and went for this one  as it came with everything I needed to get started apart from gas reg, an auto darkening mask (the one included is rubbish sorry guys but you shouldn’t bother putting it in) tungsten’s and rods.

    I am not a trained welder but have glued 100’s of old bangers together with MIG so I do have an understanding of how the machines work.

    Within half a day I was joining metal with some reasonable good looking welds. 

    I would have no hesitation in recommending this great little machine as perfectly good entry level machine for the hobby welder.

    This machine is truly amazing, as an ex motor mechanic I have stick, MIG and gas welded but never TIG welded until today. I wasn’t expecting much from my first ever TIG weld with a welder which lets be fair isn’t really classed as professional machine. But no it is to a level that I’m sure a professional would be very impressed with. My first few runs were to say the least rubbish mainly due to the setting on my mask not sensitive enough for a TIG arc causing a flash or two blinding me several times. Mask sorted and twenty minutes later I had butt welded some 1mm sheet steel with no filler rod. TIG welding will take some getting used to and a lot of practice but this machine is a fantastic bit of kit for anyone needing a TIG welder. It wins on value for money, features and ease of use. Only thing is I wish I had bought it sooner.
    Niggles only one the earth cable is not as long as I would like but other than that I’m over the moon with it. Some advice don’t try to TIG with the mask supplied get an Auto Darkening mask as you need both hands free.

    I bought this welder to replace my 40-year-old buzz-box which was producing some very untidy welds. To be fair it’s done more than its share and was due to be pensioned off.

    I also wanted the facility to do TIG welding, so scoured all the ads on eBay for IGBT welding sets (as distinct from LGBT ones . . . 😉 )

    There are IGBT welders out there from a very low price – I think (and hope ) that these are the ones which attract all the scorn on welding forums and YouTube. They do claim to be capable of TIG welding, but a lot of them don’t include the TIG torch (essential for TIG welding and can cost an extra £60 – 70 for a basic one . . . ) They also require the ‘scratch-start’ technique which can cause contamination of the weld, so I was really looking for HF start machines.

    This meant moving up the price scale to £130+ and even then they didn’t all include the TIG torch. I eventually arrived at this machine from Union Mart which finally ticked all the boxes for me – and as an unexpected bonus ticked a box I didn’t know I needed ticking. It has a pulse feature which prevents building up too much heat – say at the edge of thin sheet.

    I placed my order and was given a projected delivery date of two days from the time of placing my order. I was sceptical of this but wouldn’t really have minded if it had taken longer. I received regular updates from the company and the courier (UPS) – I had a text message at 07:30 on the appointed day giving a time slot of 13:30 – 14:30 and the courier arrived at 13:37; well within the target time. Nice polite driver too.

    On opening the box I was amazed at the size and weight of the machine – my old 180A welder weighed 75 lbs and took up a fair bit of space but I believe that this one is about 20 lbs from what I’ve read and I can keep it on a shelf in my workshop.

    It’s fitted with a UK 13A plug, so although I have a 32A socket I plugged it into the 13A supply and tried it – would have been rude not to. I could only put my hands on a 3.5mm 6013 electrode which I would normally run at 115 – 125A on my old welder but as I was only on a 13A supply I wanted to keep the mains draw low so started at 80A. To my surprise it actually managed to strike and maintain an arc but on inspection the weld was stringy so I increased the current for my next try. It was happy at an indicated 100A and made a very nice fillet weld on 10mm plate.

    All this time I’d been putting up with messy welds from my old welder and blaming myself (getting old . . .) but all the time it was the welder. Very impressed, although I haven’t done any welding with it in anger, only a quick trial run.

    As I don’t have any pure argon gas I’ve yet to try the TIG function but am hoping to get some in the very near future. There’s a neat little TIG torch with the kit so I don’t even need to buy one of those. There’s also a welding mask (of sorts, to be brutally honest . . . ) and a scratch brush. The mask is totally unsuitable for TIG welding (unless you use your third hand . . . ) but I suppose it would do for MMA welding at a pinch. I’ve got a fancy auto-darkening mask of my own so that’s not an issue for me but it could be a problem if you were expecting to start TIG welding straight away. But I expect most people who want to TIG weld would have a suitable mask anyway.

    The only negative thing I can actually think of is that the MMA torch lead and the earth lead are ridiculously short at about 2 metres – I’ve used mega long leads for many years so will make or buy the male probes to fit them to this machine. Oh, and where most of these new generation welders have a digital amps display, this machine has none. But neither did my old machine, and I used it for 40-odd years without any problems.

    Very pleased with my new purchase and up to now would recommend the company and the machine to anybody.
