Sealey Mightymig100 Professional No-Gas Mig Welder 100Amp 230V

For a cheap welder there can't be any complaints. If you require adjustability and want to do a lot of welding then going up a price bracket would be worth the investment. This has two power settings, which limits it quite a bit. I'd definitely get the model with analogue power control and the option to use gas if desired if I could go back in time. But if you're on a budget and aren't too fussy about whether your weld are a little uneven (but still strong) it will do what you need. It's easy to set up and get going. One thing I'd highly recommend is replacing the crocodile clamp with a more heavy duty one, as I initially had trouble with spotty welds. A new clamp solved that completely. I got an "ARC Welding 300A Ground Earth Clamp for ARC MMA STICK Welding Process" available on amazon. Also be sure to get a decent flux cored wire.

I have only had this for a short while but its been great for what I have needed, I now however need more power so I have upgraded for a Clarke 196 MIG - gass and gassless 180A - As I will now be welding thicker steel. The Mightymig100 is simple, user friendly and is well made, it will do most home jobs that you may need, brilliant for fence and gate making and the like. I used it for some automotive purposes but I found the limit of it penetration and was forced to upgrade quite quickly.

I am a skilled welder by trade and I was sceptical about the product. I bought it just to do a bit of welding on my car. The machine is fine and is good enough for the money. However I don't rate the fluxcore wire that comes with it. I should have bought a machine that uses gas or buy some better wire. It leaves porosity throughout the weld therefore making it a weak weld. I know how to weld and have got high standards and work for oil and gas industry. Welds are inspected to xray standard. I have prepped all material to be welded but still I get porosity. It will do the job, just not very good. Tip......always keep the torch lead as straight as possible. Any kinks will cause you hassle with wire snagging inside. Don't over tighten the wire feed rollers as this too will give you hassle. If the wire was good then I would've given 5star

I don't generally write reviews - but I'm so impressed with this little welder, I felt the need to. A good few years back, I was no stranger to welding - having a full Clarke Gas MIG setup and a full garage full of tools, which I used to restore a Porsche 944. In those days I would have shunned something like this as being the sort of welder you'd buy if you didn't know anything about welding. Anyhow....fast forward several years and we've moved to the country and downsized......which saw all of my old welding kit sold on eBay. At the time I didn't think I'd miss it - but recently a few jobs have cropped up which, with a small welder at my disposal, would have been much simpler than they turned out to be. Having spotted this on Amazon, I decided to go for it. To be honest, I wasn't expecting much - so it didn't have a lot to live up to. But, after the first use, I'm astounded how good it is for the price. Admittedly, the gasless process is a bit messier than gas-shrouded MIG. But with properly setup wire tension, this little unit delivers cracking results. Honestly - I never knew gasless could be this good. Having just acquired an ageing BMW (when will I ever learn!!) I'm expecting that over the next few years, this little box could see quite a bit of action and, of course, that's where gasless earns it's keep (welding outside on a windy day). I have to say also that the non-live torch is a real bonus (try working with a permanently live torch and see how easy that is!!!). Nice job Sealey.

Having only used an arc welder before, this was a new experience for me, but if anything, mig welding is even easier than arc, with one proviso - you have to pull the trigger to advance the welding wire and complete the circuit, or nothing will happen. (It sounds stupid, I know, but this apsect caused me some scratching of the head, initially). I ordered this inexpensive welder, which was delivered very quickly and tested it using two pieces of 5mm steel, which is probably at the top end of what you can weld with this machine. Following the instructions supplied, it was relatively easy to set up, install the welding wire and be ready for the first weld. I tacked the weld and followed up with filling in between the tacks. It took me three goes to get the wire speed and power correct, (7 and Max, respectively), and to produce a weld I was completely happy with, but found the process comfortable and quite easy, with no sticking to the metal, with the welding wire flowing smoothly into the weld and pulling away cleanly at the end. I was initially concerned that the depth of the weld may have been insufficient with this thickness of steel and ground away the weld to find that there were no visible cracks and the job held together soundly. Tacking for two seconds and moving reasonably slowly with a to-and-fro arcing movement, produced a good weld that was strong and not unattractive. Overall, I am very pleased with this machine: it is finished nicely and works well, being considerably cheaper than many on the market for a similar spec. It comes supplied with 0.45kg of welding wire. There is some spatter, when welding and quite a lot of fumes, so you need to work in a well ventilated work space or use extraction; other than that, it produces quite a clean weld with little slag to chip away. All the other reviews for this maching are good and I can agree that this is well worth the money and good for a new welder or one new to mig welding, as I am - a good machine to start out on and not a bad one for experienced welders who want something inexpensive to use in the home workshop.
