Amazing Value for Money
Great little inverter welder. I haven't welded anything for about 20 years and not only was i shocked at the price but also the ease of use. It's tiny, weighs less than my cat and is considerably easier to carry about. It comes with a little fold together mask which works fine for little jobs. Very easy to strike an arc with it and the old skills were all flooding back in no time. I suspect it might not be great for big jobs, it's definitely a home use model but as that's what I'm using it for it's great for me.

A fantastic cheap welder
I was a little suspect of whether this little welder would be any good as it i8s so cheap. I read all the reviews and thought I'd risk it. I have taught Design for many years, done up many old cars and made many metal things over the years, all with what would be considered 'better quality' kit, but I was NOT disappointed. This is a lovely little bit of kit for the price, and for smaller jobs (that is jobs with thinner metals like car bodies) this is extremely easy to use and a lot les hassle to cart around than the larger, more industrial machines I usually use. Also, I would imagine that it is a great little starter machine and ideal for the occasional or hobby user. Highly recommended.

STUNNING WELDER and YES it only uses a 13A UK fuse in a normal plug socket, even at full power!
I just welded, with 1.6mm rods a 1mm piece of stainless steel tubing to another! There are few questions and mostly incorrect answers about this 120 amp welder and it's 13 Amp fuse: Let me make this crystal clear for everyone "guessing and writing false info without knowing real facts": This welder does NOT say 120 Amps "AC" does it? NO it doesn't... just look at the title again please! It CLEARLY STATES 120 amps "DC"! UK (and the others) plug sockets use AC = Alternating current DC means direct current Something must be happening inside mustn't it? and it must be within the laws of physics! So read on: Now, as it happens, even AC/DC info is here is just to highlight the fact to READ THE TITLE PROPERLY The absolute maximum fuse you would put in a UK plug for a residential socket is 13 amps, not 120 amps: HOLD FIRE! Am I agreeing with the incorrect answers on here? Erm... No, sorry, I'm not... READ AND LEARN So how does this work, without blowing a 13 amp AC fuse then? First it changes the AC voltage to DC... Would this still kill a 13 amp fuse? Yes but something is happening! Second It drops that DC voltage to about 25 volts... Even more is happening now Now, to make it simpler, let's momentarily drop the fairly irrelevant AC/DC A "240 volts" 13 amp fuse CAN handle "25 volts" at 120 amps Oh gosh! This guy might know some FACTS! Let's make some home observations shall we? Go and look at a 3,000 watts kettle (make a cuppa in fact!). Low and behold it will have a 13 amps fuse. It only needs that because 3,000 Watts divided by 240 volts = 12.5 amps (it's called a sum!) 12.5 amps is less than 13 amps isn't it? Let's do the welder: "25" (not 240) volts times 120 amps = 3,000 Watts... Has a similarity penny dropped? 3,000 watts only needs a 12.5 amps fuse doesn't it, when it all starts at the socket at 240 volts and works down to a lesser voltage at higher amps... Less than a 13 amps 240 volts UK plug socket fuse in the end! "Watts are a universal measurement" (no time to explain here) So when you see the title of 120 amp welder and it even says "DC" then you 100% know that, because all UK sockets are AC, then something MUST BE CHANGING INSIDE mustn't it! No physics being re-written, no warp drive, no unicorns (sorry believers), just plain and simple FACTS of DROPPING THE VOLTAGE FIRST! If you feel like posting some incorrect info please have a look at the readily available facts on university and professional electrician sites on the internet. Enjoy the brew, and I hope you didn't plug the kettle into a three phase industry power outlet or join you and your neighbour's houses together to get the 3,000 watts power!

Fantastic welder
I bought this welder to work on a project for my son. The last time I used a welder was 44 years ago as a 2nd year sheet metal worker. I unpacked this welder and was surprised at how small it was but I was surprised and delighted at how easy it was to operate it. I have made and welded spindles and a frame of 50mm x 25mm x 3mm rectangular box section and this small but compact welder has stood up to the challenge. I am really glad I bought it and I would highly recommend it to everyone.

Amazing!
I've done a fair bit of stick welding the last few years so decided to get one myself. After looking at a few options this caught my eye. The reviews were good but I almost couldn't believe that an arc unit this small could be any good. However the price was good as well as the review so I thought why not... So glad I did! Amazing little thing and it has just as much power as a bigger and much more expensive model. And it all folds away with a carry case. Couldn't really ask for much more out of a welding machine. My father in law laughed when he saw it, being a tradesman for 30 years, but has since got one of these for himself! 100% would recommend!

Welder review
Good little welder, does a good job considering the size, light to carry and use

Easy to use.
It does the job! Plug in and go. Not sure what rods I was using, 2mm? (Was given a bundle). I'm not a welder but have tried in the past using old machines. This is a tiny welder but as a novice I found it very easy to use. Take it out of the case, throw the supplied mask away, plug in the earth lead and rod holder and start welding. I did invest in an auto darkening helmet which is amazing. I bought the welder in order to modify a boat trailer, and it's already paid for itself. Once I've completed the trailer I'll be looking for more jobs, maybe I'll make some garden sculptures!

Bang on best bit of kit for the money
Well what can I say value for money bang on , Delivery bang on , & This machine is a cracking little piece of kit I cannot believe how well it works I’ve done 24 welds today and made a frame out of 50x50x4 box and it never missed a beat I would recommend this welder comes with all the bits kit only one down side is the mask buy a proper one I have to give it 10 out 10
