KP3701-1 - Lincoln KP3701-1 Inside Polycarbonate Lens for Viking 3250D FGS (2-Pack)

Maintain Peak Clarity with Lincoln KP3701-1 Inside Cover Lenses

For professional welders who rely on the advanced optics of the Lincoln Viking 3250D FGS Series helmets, maintaining a clear view is non-negotiable. The Lincoln KP3701-1 Inside Cover Lens is a genuine replacement part designed specifically to protect the interior face of your auto-darkening filter (ADF). Over time, even the inside of a welding helmet can accumulate dust, sweat, and fine particulate matter that obscures vision and causes eye strain. Replacing your inside cover lens regularly ensures that you are getting the full benefit of your helmet's 4C Lens Technology.

These lenses are manufactured from high-grade polycarbonate, a material chosen for its exceptional durability and optical purity. Unlike generic plastic replacements, these genuine Lincoln lenses are engineered to minimize distortion, ensuring that the weld puddle remains sharp and defined. The lens measures 108.3 mm x 78.3 mm x 1 mm, providing a precise snap-fit seal that prevents debris from bypassing the lens and damaging the expensive ADF cartridge behind it. This tight tolerance is critical for maintaining the integrity of the helmet's protective system.

One of the standout features of the KP3701-1 is its resistance to fogging. Welding in humid environments or during intense, long-duration welds can often lead to lens clouding. The material properties of this inside cover lens help mitigate this issue, keeping your vision clear so you can focus on the arc. This package contains two (2) inside cover lenses, allowing you to swap out a dirty or scratched lens immediately and keep a spare in your kit for future maintenance. By using genuine Lincoln Electric consumables, you ensure the longevity of your equipment and the safety of your eyes.
