Auto-Darkening with adjustable sensitivity and wide shade selection (DIN 6 to 13)
While auto-darkening has become the de-facto standard in today’s welding helmets, the Lincoln 3350’s screens come with a wide range of easily adjustable sensitivities (DIN 6 to 13), ensuring you won’t get flashed while working, and enabling you to work in any lighting environment with ease.
Perfect 1/1/1/1 Optical Clarity
The new Viking auto-darkening cartridges rate highly in all four optical categories: Optical Class, Diffusion of Light Class, Variations in Luminous Transmittance and Angle Dependence of Luminous Transmittance Class. This means you’ll have crystal-clear clarity at all times.
New: The latest 4C lens technology takes the helmet’s optical clarity to a whole new level, making the view crisper, clearer and cleaner.
Massive View Window Size
With a viewing screen size of 3.74in x 3.34in (95mm x 85mm), The Viking 3350 (K3034-3) has an enviable field of vision, enabling work even in tight spots where vision is impaired.
Awesome Styles For Every Taste
Here are a few different styles you might prefer:
Heavy, especially after a full day of welding
Due to the large viewing screen, the Lincoln Viking 3350 is a little face heavy, which you can especially feel after a full day of welding. Luckily the suspension system is comfortable, and in addition to the highly adjustable headgear, the helmet’s weight is usually not much of a problem.
Glossy black coating easily scratched
Despite being nice to look at, the glossy black finish of this helmet is easily scratched, so be careful – especially when you’re working in a tight spot. One amazon customer mentioned welding with the helmet for only a couple of hours before noticing some scratches on the hood.
