15 April 2025good as to be expected
-
02 April 2025Used this type of gun before great
-
24 March 2025Bought to try and weld aluminium as my old MIG could not cope and could not feed the soft aluminium wire without constant buckling. This gun is not too heavy and has a 5 metre cable. No problems at all, feeds the wire very well, easy to load and use. Feels robust and well built. Will be trying it out on vehicle chassis as the 5 metre cable should reach the back and both sides.
-

07 October 2023I bought this as an attachment for my MIG180 to allow me to expand into aluminium welding. I have yet to use it but it seems well made and I have watched it in use on the promotional videos, so I would expect to be able to recommend it to my friends and acquaintances.

28 May 2023Can't wait to try this out
-
19 May 2023Already had and used a ** version.Whilst more expensive but not excessive,This R-Tech version is far superior
-
27 March 2023Any one who thinks they cannot weld aluminium, Well you can with this spool-** and ist very easy top product
-
15 March 2023Easy to use first time straight from the box.
-
12 February 2023I brought the spool ** as I don’t now how to tig weld, it’s such a easy item to use & is very fast, I’m a complete novice at aluminium welding & even I managed to get good results in a very shot time, it’s a very handy piece of equipment to have
-
21 January 2023Absolutely brilliant no complaints at all and the price unbeatable super fast delivery r-tech never fail to make me smile
-
27 November 2022Fantastic Welder
-
20 November 2022Bit the bullet and bought this along with my new mig from R-Tech. Have in no way tried it but I think it is a very nice bit of kit that is really well made. I dont do much welding on Alluminium but its nice to have there for the odd times the need arises.
-
29 October 2022Used for fabrication & repairs in my home workshop, easy to use for any home welder. Excellent quality & well-made product
-
29 July 2022I have never used a spool ** before and had a alloy section to weld so easy to use with no practice as it was a rush job really impressed and the help I received in getting the wire I would need to start with from your team very pleased.
-
25 April 2022Ace
-
24 April 2022looked at these for a while, really happy i contacted R-Tech and got one.

14 February 2022Works a treat, first spool ** I’ve used, no more birds nests at the rollers while trying to keep the torch lead as straight as possible!
-
03 February 2022Not used the ** yet, but the equipment looks great as I expected
-
27 January 2022Recomended
-
19 January 2022Have tried to weld alloys in the past with limited success, the spool ** is another level and has removed the stoppages that plagued me in the past. I am a DIY user and the ease of using the gun is improving my results, Although listed as an entry level item the build quality is superb and comfortable to handle in use.
-
14 January 2022This machine should do everything I want for my hobby engineering. I was looking for a better quality MIG welder, to replace my aging one, with the ability to weld aluminium and this fits the bill.
-
22 December 2021Not used the spool ** yet but it looks and feels as good a standard as all of the other R-TECH items I have.
-
21 December 2021Spot on
-
15 December 2021Havent jad chance to use this yet but seems sturdy and well built looking forward to trying this out
-
02 December 2021excellent product easy to handle
-
01 December 2021To be used to make framing . Only tried out today, first impression easy to use so I would think it’s suitable for anyone keen to weld. Appears good quality.
-
30 November 2021Occasional use,small jobs,recommend to anyone who doesn't want to move on to tig (space and expense of another machine)quality kit as you'd expect from R-TECH ideal for small jobs but I'm sure would work all day if needed
-
26 November 2021Excellent.
-
25 November 2021As ever great quality built in the UK equipment does what it says on the can.
-
02 November 2021excellent

13 October 2021Welding ally bodies. Recommended for any workshop. Very well made.
-
27 September 2021Good quality and as expected
-
16 September 2021For alloy welding. Anyone who fancies a shot of welding alloy Very pleased with this.
-
10 September 2021Sorry for the delay in the review as it took time to set my project up. The spool ** works fantastic as a diy welder and is easy to set up. Well worth the money.
-
30 August 2021Fantastic products
-
29 August 2021Quality product with good length hose / cable
-
26 July 2021100%
-
30 June 2021Looks a nice tool to use, but it is large and heavy, especially when the spool is fitted.
-
30 June 2021Ordering could not have been any simpler. Got exactly what I wanted and a pretty quick
-
23 June 2021***
-
21 June 2021Very easy to use
-
02 June 2021I have not used this product yet. It certainly looks a good quality product.
-
01 June 2021Works well but no instructions at all or guidance in the welder manual( this says to use a Teflon liner and roller ). Feels a bit cheaply made and might not last long
-
15 May 2021works brilliantly
-
24 April 2021Easy to use with quality
-
02 April 2021quality piece of kit
-
18 March 2021I use this for light to medium aluminium welding, I would recommend this to those wishing to weld aluminium without having to buy a different machine. The spool ** has very long control leads, a big asset, it is well made and runs smoothly.
-
14 March 2021Ease of swopping from ordinary MIG torch to spool ** is very easy , great add -on to the machine and well worth the very reasonable extra cost.
-
03 February 2021Haven’t had a chance to use it yet but the quality seems good
-
28 January 2021Ace for birmabright landrover panels. But also good on 0.6m stainless wire. Buy both ally wire grades for options, 0.8mm. Well worth buying with a mig set or just anyway :o) The wire drive looks decent quality.

-
14 July 2020I haven’t used it yet so can only rate it on the information from what other people say. The info I got from YouTube Doubleboost channel made me decide to buy your kit. I am a total novice and have never welded anything this is going to be my retirement hobby.
-
08 July 2020Well made bit of kit
-
06 June 2020A good addition to the 250 amp mig welder. Makes an already good welder even more versatile.

-
19 May 2020Fabrication Great product
-
10 May 2020Great bit of equipment. I've used it already and can't believe the quality of aluminium welds it produces
-
06 May 2020Brilliant spool *** for aluminium welding !! Top class !!
-
30 April 2020I use this product for repairs, but it is intended for my own fabrication work. I would reccommend this product to people who occasionally need to weld aluminium and need a tool that can be quickly set up. Especially for those that want to utilise exisiting welders. In typical R-Tech fassion. This is a decent quality product as one might expect. I had a bit of trouble getting used to the wire feed to begin with. I had a little trouble with the spool sticking a bit. Which was causing inconsistencies in the wire speed. A quick call to Customer Support, helped to make sense of things. But it probably took a couple of hours to settle everything down. The situation eased as the spool discharged , which resulted in less friction and a more stable wire speed. I have held off giving a review, until I have been able to make effective welds that hold together. This I have now achieved. I have managed a weld that looks similar to how a weld should look, as opposed to pile of pigeon droppings ! I am pleased to say that I have had the confidence to do a couple of hours worth of welding on a customer's work and been satisfied with the results. Now everything is running smoothly, the results are starting to appear. I have great *** in R-Tech products and I believe that this aluminium welding torch will be no exception. It is indeed starting to produce some worthwhile results after only a couple of hours' practice.

02 April 2020Not used it yet

15 April 2018I use R-tech equipment for small scale project and prototype work,this equipment is perfect for advanced welders and beginners alike,being an inverter mig it is smooth in operation and very forgiving and easy to use and adjust the case of the machine is robust but not overly heavy I have been using my mig and plasma cutter for5+ years now without any faults but I can phone R-tech tech anytime for advice parts or repair
