I did a lot of research, and results indicate from reviews to not even think about other auto-darkening helmets - and for this helmet, those reviews are spot on (correct). Stay away from Harbor-Freight, YesWelder, even Miller Digital Elite 2.0, etc. I'm not stating this Lincoln is better than Miller Digital Elite 2.0, but rather for the weekend DiYer, this is your go-to helmet for Flux-Core, MiG, etc. As soon as I opened the box, I set the shade to 10 (for thin sheet metal flux core), and set the lag-time for becoming clear (after the arc distinguishes) to short "S", and went to the garage and fired up the new Lincoln 90-iFC flux core welder (110 Volts AC). Before I struck the arc, the lens was very clear. Once I struck an arc, the lens auto-darkened within 1/25,000 seconds, which is 200 times faster than the human "look away" reflex time when accidentally looking at the sun (1/125 second). The look-away reflex is a natural response built into the eye (central nervous system) from preventing retinal burns and burning the eyes out from bright lights. Amazingly, the arc appears very small and is not inflated like cheap lenses will do. The diameter of the visible arc during flux core (0.035 Lincoln flux wire) on 1/8" steel was about 1/8", so very small. As a result I could run a small bead like a micro-surgeon. The color of the arc is a blue-white color, and the small molten bead looks like liquid mercury, so there's no messing up on whether the bead is gluing together both side of the lap or butt being welded. The helmet's very comfortable when tightened around my head with a Lincoln do-rag on - yes, you need a do-rag for flux core, since it's spatter on steroids - everywhere. Be sure to wear long sleeve shirts - no matter how hot it is outside, as well as pants, and full suede gloves. The bright arc releases a lot of UV, which has proven to be a strong carcinogen - we're talking BCC (basal cell carcinomas) and other skin melanomas. Basically, the skin cancers that result in a horrible death - so don't be a fool.

Two of our three grandsons love these helmets, They find that the color of the welding picture is more true and still protects their eyes! The view out of them is noticeably larger which helps both lay better looking welds !

This is a very nice Helmet very comfortable. There’s so many features making the job a lot easier and faster the auto adjust is very nice the head band is extremely comfortable this is a must have if you don’t already have. Lincoln electric did a very nice job producing this model. On the plus side Amazon had the cheapest price I could find even the company I work for which gets price breaks ordering from company’s like miller and Lincoln couldn’t beat the Amazon price for this helmet I’m very happy

My welding has improved with the improved visibility offered by the Lincoln Electric K3034-4 Viking 3350 helmet. I am a beginning welder and after struggling to visualize the puddle with my cheap auto-darkening helmet I finally took the leap and bought the Viking. It is definitely worth the price to upgrade if you can swing it. The helmet is very well made and comes with good instructions.

Well worth the money!!! I'm a professional welder with 21yrs of experience behind a hood. I must say this is by far the best hood I've ever owned. The visibility and clarity is way better than I expected it could ever be. The head gear feels cheap but is extremely comfortable so we'll see. I showed 6 other guys at work this morning and every one of them was highly impressed. I don't know the durability or longevity of this hood but if it only lasted a yr I would buy one every yr. This hood is a game changer for sure. I highly recommend spending the extra cash

They might be a little pricey but I have been welding for 4 years and these hoods are the only thing I will use because of the quality lens and also the head gear is so comfy. Wil buy again if I need to

I love this helmet! My last few helmets were uncomfortable to wear for long periods of time but I can wear this all day no problem. It's fairly lightweight and the adjustment features on this make it easy to fit onto anyone's head. I've also never had to change the batteries on this one as it has a solar panel on it. So as long as you keep welding it'll keep working. The screen on this is nice and big. Plus it's shade is a natural blue instead of a green, which helps you see better (I don't know the specific terms or science behind it but It is much easier to see out of).

I weld every day and I've had this helmet for a few years now. The helmet itself performs flawlessly. But I have to constantly retighten the head gear. If I had to weld for long periods of time I would've trashed it by now or retro fitted better head gear. Also the grind mode button can be pushed unintentionally when getting your head into thght spots, it always sucks to get flashed. Lincoln! Get better head gear!
