LINCOLN ELECTRIC 2x4 C-Series Auto-Darkening Welding Lens Variable Shade 8-13 KP3775-1

Awesome lens from an amazing company. This allowed me to see what I was doing so much more clearly that it significantly and rapidly improved my ability to learn how to weld in school. I put the hood facing out toward the rear of my car, resting on the back seat headrest so that it’s always getting some sun and I’ve had no battery issues using it for about 10 hours a day, 4-5 days a week. Battery replacements are super cheap if you ever do need to replace it and best of all Lincoln stands by their word for the warranty of 2 years! My 2nd Viking lens had a small defect in the top left of the lens, I emailed Lincoln customer service and 3 days later I get a new one in the mail. Hot damn that’s some stellar service and I will keep buying these for every hood I own. Update: 4 months of solid, near daily use later and still no issues with my Lincoln 4c with original batteries. Does Tig, Mig, and Stick all flawlessly. Side note: you can easily file or cut down any flip up lens adapter to accommodate this lens just make sure you sandwich it in between two clear poly plates back and front to protect it while grinding.

New to these auto lens inserts, I bought another brand. It worked well for a time and then stopped taking a charge. This model doesn’t require all that because it has solar panels. Crisp and worth the money. Modern auto helmets are so heavy. Slap this lens in an old school light Huntsman etc. and your neck will thank you. Lincoln is a reputable brand you can trust.

Seeing through it is spectacular. I just don't understand why it doesn't recharge it self when using. I had to change the batteries the day I opened it up. That's why it's a 3 star review. Over-all you see everything when your welding. Update 6 months after use It got a Crack in the screen and in 24 hours Lincoln sent me a brand new lens so now they are getting a 5 star review and the lens works great. I still wish it didn't need batteries.

It works pretty good, hasn't flashed me too many times, and the lens is very clear. I work with high amperage MIG (1/16'' metal core spray transfer, ~340a) and I have to use shade 13, it's more like a 11.5 on my Miller T94i PAPR. If I use it at shade 12 (what I usually use on every other hood) I get a spot in my vision. The shade level around the edges of the lens also tapers off. There's a oval plunked in the box of the lens where it's shaded to the level you have it at, but in the corners and along the sides it'll be a shade 9 or 10. Kind of annoying, especially if you're having to use the edges of your lens to see what you're doing.

Great auto lens for a flip up hood. Like the blue gray color of the weld puddle. Does chewy through battery’s.

By far the most clear lens i have ever used. Fits pipeliner hoods with no modifications to the hood. On a fibre metal tiger hood (flip up), you have to open up the slot a little with a flat file, dremel, or burr bit, but you can still put a cover lens on each side after you do. This lens is clearer, has better color, and has more adjustability than any of the speedglas products i have used over the years. Also blows away wens lens ultra cool blue for about $20 less. Also, a word about color, this one has no green, orange, blue, red tint to it...it is real life color as your eyes see and that really seems to enhance the clarity for me.

Update: I purchased this lens March or 2024. I have had this lens replaced under warranty for the first time September of 2025. The second one was replaced under warranty March of 2026. It is the end of April 2026 and now this one is broken too. Since I am outside the 2 year warranty window I can't get a free replacement. THIS IS THE MOST UNRELIABLE LENS YOU CAN BUY. IF YOU EXPECT TO MAKE MONEY WELDING DO NOT BUY THIS. Not reliable. Clarity is great but I replaced mine twice within the 2 year warranty period. Only reason why I gave 2 stars was because customer service was great. Will not buy again.

Weld with it 40+ hours a week great lense although seems to chew threw batteries

Awesome lens
