Very good little welder, im not a welder by trade but i like to tinker and wanted to weld for a long time, with the right gear and a few hours with some scrap i was able to weld some pretty good beads for flux core

got this for my boyfriend when he graduated from his welding program it is so worth the money. It’s very compact and transportable but still packs a punch and will get the job done. Overall, we love.

The Lincoln Electric 90i FC is a fantastic compact welder! Lightweight with a handy shoulder strap, it’s ideal for quick repairs. The metal case adds durability, and performance is smooth. Highly recommend for DIYers!

As a hobbyist/home handyman, I considered myself the world's worst welder using a HF buzzbox. My welds were atrocious and could not be trusted to hold two pieces of paper together. I purchased the Lincoln 90i FC and guess what? My welds improved instantly. Though I may have graduated to world's second worst welder, I can definitely weld two pieces of metal together and have them stick. What a world of difference a quality tool makes. I can positively say that any deficiency in the quality of my welds squarely lies on my shoulders and cannot be blamed on the machine. The 90i FC is a very capable unit and has all the power I need as it will easily trip a 20A breaker on the highest setting. Can't imagine being able to use a more powerful unit without going to 220v. I also considered going with the 90i FC mig but decided against it because of the added expense and learning curve of adding a gas cylinder. Sure it might be better but unless I get into more serious work, this is all the machine I think I will need.

I didnt expect much from this little 110 wore box. I got it for light duty repairs and easy portability. It looses a star for not having a dang handle. That shoulder strap stinks. I put one on it anyway but man...always make a welder intended to move around like this one with a handle. Also the star loss is because it only takes 1 lb spools. I know they were trying to make it ultra portable, but come on at least 2lb spools guys. At least. Other than that this thing is amazing and welds great. Best flux core welder ive ever had. And way stronger than advertised. I think they do that thing where they claim it will only weld so thick of steel but make it stronger so its impossible to not have enough juice than to weld what is advertised. I have welded half inch plate with this welder. It was just supposed to be a quick fix till I could get back to a big 220 stick welder I have, when I went to cut it down to fix it properly, this little box had gotten penetration half way though 1/2 in plate on one pass! I couldn't believe it. In any case, worth the money. Works great. Long duty cycle for such a small unit. If you are welding 1/4 steel or less all the time you'd never not be able to weld it. Only drawback is its not a mig /flux combo but...that unit is like 3 times the price so.

Works as advertised. If you are a welder you know what you need and this is a quality machine. If you are a guy trying to weld I will post a picture of a job I’m doing. I have a big 208/230 welder and I mostly use this because it can do most jobs and feels like it weighs 3 pounds. Also if you need more wire in a pinch you can go to Lowe’s and grab a roll.

I had a Lincoln 140 welder before and lost it in a fire. This one seems to weld just as good if not better than it. The big difference is that this one is light as a feather. It’s a switching type power supply instead of a large transformer type which is what makes it so light. I used it this weekend to repair a grader blade for my tractor. The wire speed and amperage control seemed easier to set than my old one. I burned through the steel in one place, but I was able to turn the amperage down and the wire speed up to build it back up and repair the hole pretty easily. I’m not sure if there’s any application where I would need to carry this thing as I was welding but you really could it is so light. Very happy with it and the price was a lot cheaper than the transformer type welders.

i sold my forney, a 120v 120A max flux core welder for $100 and bought this. still 120v 120A, but i wanted something with: - more granular voltage control, better than the forneys "sheet metal/thin plate" two-voltage rocker switch. having an infinitely adjustable dial between 1-10 is spectacular for me. - *significant* savings in size and weight, which meant an inverter welder. my forney was probably 40lbs and the size of a large laundry basket. awkward to move. this thing is the size and weight of a large shoebox... - ive only used it on a few jobs so far, but i swear using inverted power splatters less, and makes for a killer weld almost every time. as i said, it almost feels like cheating compared to my old machine. - the torch, workclamp, and power cable are all high quality - cold feed switch makes swapping spools effortless AND safe - keep in mind since this is a flux core only unit, the torch has no big fat gas shield on the end that normally also protects the electrode. i LOVE it, gives me a great view of my work at any angle. just gotta be careful and watch your CTWD or youll tear through electodes. *thats a 12" laptop leaning against it in the pic, for size reference*
