KP2931-1 - Lincoln Viking 2450/750S Inside Clear Lens Replacement (5-Pack)

Protect Your Vision and Equipment

The Lincoln Electric KP2931-1 Inside Clear Cover Lens is an essential consumable for owners of the popular VIKING 2450 and 750S Series welding helmets. Designed to fit precisely within the helmet shell, this lens serves as the final barrier between your eyes and the sophisticated Auto-Darkening Filter (ADF). Over time, the inside lens of a welding helmet can become clouded due to accumulation of sweat, fine particulate matter, and general wear from cleaning. Replacing this lens is critical not only for maintaining a clear view of the weld puddle but also for ensuring the longevity of the ADF unit itself.

Precision Fit for Viking Series

Manufactured to exact specifications, these lenses measure 98.5 mm x 66.5 mm x 1.0 mm (3.88 in. x 2.62 in. x 0.04 in.). This precise sizing ensures a tight seal against the ADF cartridge, preventing dust and smoke from bypassing the lens and damaging the filter's delicate electronics or sensors. The KP2931-1 is specifically engineered for the Viking 2450 and 750S series, guaranteeing compatibility and ease of installation. Unlike generic universal lenses that may rattle or leave gaps, these genuine Lincoln Electric parts snap securely into place.

Optical Clarity and Durability

Welding requires absolute focus and visual precision. A scratched or foggy inside lens can cause eye strain and lead to weld defects. These clear cover lenses are made from high-quality, impact-resistant polycarbonate that provides superior optical clarity. They are robust enough to withstand the rigors of a workshop environment while remaining lightweight. Regular replacement of the inside cover lens is a simple maintenance step that dramatically improves the welding experience, allowing you to see the arc and puddle with the definition intended by the helmet's high-quality optics.

Convenient 5-Pack

This product comes as a package of five lenses, providing excellent value and ensuring you have replacements ready when needed. Whether you are a professional fabricator or a hobbyist, keeping a stock of consumables like the KP2931-1 ensures that you never have to compromise on safety or visibility during a project.
