KP4628-1 - Lincoln Viking 2450/3350 Outside Cover Lens Bulk 50-Pack

High-Volume Protection for Viking Series Helmets

The Lincoln Electric KP4628-1 Bulk Outside Cover Lens pack is an essential consumable inventory item for industrial facilities and professional fabrication shops utilizing the VIKING™ 2450 and 3350 Series welding helmets. This package contains 50 high-quality replacement lenses, designed to serve as the first line of defense for the sophisticated auto-darkening filter (ADF) technology housed within these premium helmets. By maintaining a fresh stock of cover lenses, facility managers and safety coordinators ensure that welding personnel maintain optimal visibility and compliance with safety standards without interruption.

Engineered from durable polycarbonate material, these lenses are manufactured to meet rigorous safety specifications, including ANSI Z87.1+ and CSA Z94.3. This certification guarantees that the lenses provide robust protection against high-velocity impacts, flying debris, and the intense heat and spatter generated during arc welding processes. The lens dimensions are precision-cut to 114 x 133 x 1.0 mm (4.5 x 5.25 x .04 in.), ensuring a perfect seal against the helmet shell to prevent smoke and particulate ingress that could damage the ADF or obscure the welder's vision.

In an industrial MRO context, the KP4628-1 bulk pack represents a strategic procurement choice. Purchasing in 50-count quantities significantly reduces the per-unit cost compared to smaller blister packs, optimizing the operational budget for welding consumables. Furthermore, the consistent use of genuine Lincoln Electric parts guarantees compatibility and performance, eliminating the fitment issues often associated with generic aftermarket alternatives. These lenses are clear, offering superior optical quality that complements the 4C® Lens Technology found in newer Viking models, ensuring that the welder's view remains sharp and color-accurate.

Regular replacement of the outside cover lens is critical for maintaining weld quality. A pitted or scratched lens diffuses light, causing glare and reducing contrast, which can lead to weld defects. By providing easy access to replacement lenses through this bulk offering, organizations encourage welders to swap out damaged screens promptly, maintaining high productivity and safety standards on the shop floor.
