I Purchased this helmet almost 2 years ago. I weld almost every day, wearing this helmet for 6-8 hours at a time doing piece work. Best hood I have owned. No flashing and very comfortable. Highly recommend!

The media could not be loaded. Purchase this helmet about two years ago.When I started welding school at a community college, it has lasted me through s m a w welding, tig, and currently at my job, I just got using flux core. It is a reliable and great helmet, 5 out of 5 stars. Really like the grinding mode just don't forget to switch it off before Welding or else youll get blinded for the next 10 min or so lol

I wanted to try out the new auto darkening technology, and so glad I did. I did use a Jackson auto darkening hood and it was my favorite for years and I still have it. This Lincoln hood with the wide view and the new technology is the Best!! It is unbelievable how much better I can see the puddle. I’ve had this hood for a few years now and if for some reason it broke or stopped working, I would buy another right now. I recommend giving it a try.

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.
