Works great and an exceptional value
Tiny, light and super portable. But it welds just great on thin things. I use it for welds on stainless steel tables that are 14-18 gauge instead of using my big welder. The lower power is perfect and I don't have to keep changing out wire spools back and forth.

Lincoln has done it again, you won't be sorry buying this one!
This is a small machine, but performs like it's the bully on the block. Welds perfect welds, just like a Lincoln. The ad I saw was correct, you can carry this one via its strap on your shoulder to the welding location. Just plug in set controls and weld. No problems yet. Really like the size of this one!!

Super portable, easy to use.
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.

Best flux core welder ive ever used
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.

Effortless Welding for Car Restoration Projects
This welder has been a game-changer for me during the restoration of my vintage 1950 Ford hearse conversion. The torch is incredibly easy to handle, making precision welding on sheet metal a breeze. I love how portable the machine is, allowing me to move around the car effortlessly. Being able to run it on 110 power sources is a huge plus as I can reach outlets conveniently. Once I dialed in the settings, maintaining them has been a smooth process. This welder has been trouble-free so far, making it perfect for light welding tasks. Highly recommend it for anyone working on similar projects!

Easy to operate.
The Lincon 90i was everything I had heard about them. I am a beginner to welding and only need one from time to time. It was very easy to set up and operate. It welded perfectly and allows me to take on the small jobs around my place with confidence.

La encontre de oferta y ha sido una de mis mejores compras, facilita mucho que sea microalambre si no tienes mucha experiencia soldando. He hecho varios trabajos y no he tenido ningun problema.
