Should I Buy It?

If you're looking for a reliable welder that can comfortably handle a wide range of metals, the Lincoln Welder is a strong choice. Its portability and dual voltage feature make it versatile. However, it's important to consider whether the issues some customers have reported, such as limitations on adjustability and sometimes receiving faulty units, could be a deal-breaker for you.

    • Great Welder for the Money.
Style: Welder
This is a great machine for a hobbyist, or even a low production shop. The fact that it is 110 and 220v makes it extremely portable, and you're not limited to using it in a certain area(albeit, it will be at a lower amperage). I agree with the other reviews... if you are looking at a 900 dollar welder, go ahead and get this Lincoln. Full warranty for 3 years, IIRC; although most likely you will never need it. There are a couple of cons even though I gave it a 5 star review. The pulse feature is limited to 20PPS. Usually, this is fine, but if you are really trying to control heat on thin metal, it would be nice to have more adjustability in the waveform(it's currently locked at 50%) and a higher PPS. 99.9% of people will never notice this. As other mentioned, the HF start pulse is probably over 10amps, and on super thin sheet metal this might be problematic. It would be nice to have some adjustability here. That said.... if you want those 2 very small quibbles, you can step up to the Miller at almost 3X the cost. ... show more

    • Did not work straight outta the box !
Style: Welder
Didn't work straight outta the box. Plugged it in and absolutely nothing. Returned it for a full refund quick and easy.... picked up the exact same unit from my local welding supplier and it works flawlessly. Definitely a great machine but it must have taken a beating on the delivery trip. It has very fragile parts inside and needs to be handled very carefully. I don't recommend that delivery method as I honestly suspect the machine was damaged during shipping... ... show more

So far ive welded 316 stainless for my boat and it worked flawlessly. I also welded up some sheet metal and stainless exhaust on my 67 camaro rsss and again near flawless welds. I also welded up round and flatbar on my 55 & 48 panhead projects, and once again nearly perfect welds. There might be better welding machines out there but I highly recomend this one! 👍👍 ... show more

    • DOA like all the other 1 star buyers
Style: Welder
Brand new $2400 plus tax for a boat anchor! Fan does not even come on. Returned for a refund, and Amazon's policy is refund 1-5 days after they receive it. After 5 days no refund, I called and they said it will be 30 days, so they violated their own policy. BUY A MILLER!

    • The welder depends on your skill level
Style: Welder
I think it's overrated and overpriced, I bought a Miller thunderbolt CC AC DC 225 20yrs ago for 350.00 and added a cheap Century high frequency box for another 100.00 plus a Tweeco tig torch and can weld anything with it that can be welded with the Lincoln. The benefit the Lincoln has is the foot pedal to control your heat and being able to run off dual voltages, Would I buy the Lincoln again NO. ... show more

Machine works great runs like a champ I'm a pipe fitter and weld every day so I have experience with all different types of machines this happens to be the machine I bought for home because it's light enough to carry with one hand and can still get the job done around the house. The stinger, tig torch, and ground clamp aren't very impressive at I'm not a fan of how the tig set up is because there is no shutoff valve and the torch which is the traditional way it's back at the lead when you plug it into the machine I eventually got tired of the factory tig setup and change it how it how 99% of the industry runs their tig setup on a tig/stick machine ... show more

    • Glad i bought this machine.
Style: Welder
Going through these reviews i was a bit worried about purchasing this machine. About 10 hours in on the welder in AC and DC and no issues. Great arc starts, never any false starts, and haven't overheated . Granted, I am not doing production welding, so far i have no complaints. Easy to use, easier to set up. Ill come back to this if i have any issues. Bought this machine for the HF start, and AC ability. Not disappointing. ... show more

This welder is great. The quality of every component is very good. I'm glad I spent a little more and got this Lincoln Tig 200. I bought a tank of Argon , plugged it into 110 regular outlet and laid a beautiful bead first time. Shipping was very fast also
