KP3775-1 - Lincoln Viking 2x4C Auto-Darkening Lens Cartridge Shade 8-13

High-Performance Optics for Industrial Applications

The Lincoln Electric VIKING™ 2x4C® Series Auto-Darkening Lens (KP3775-1) represents a significant upgrade for professional welders utilizing traditional passive helmets, pipeline hoods, or pancake shields. Engineered to fit the standard 2-inch by 4.25-inch cartridge opening, this lens integrates Lincoln's proprietary 4C® Lens Technology into a compact, rugged form factor designed for industrial environments. The 4C technology (Clarity, Color, Carat, Cut) filters out the traditional lime-green tint found in standard auto-darkening filters, delivering a true-color view of the arc, puddle, and base material. This enhanced optical clarity is critical for precision work in sectors such as pipeline construction, heavy fabrication, and structural steel erection.

Robust Construction and Versatile Control

Built to withstand the rigorous demands of the job site, the KP3775-1 features a high-temperature ABS lens housing. This specialized casing reduces the risk of lens failure due to heat deformation, a common issue when welding at high amperages or in confined spaces where the lens is in close proximity to the arc. The unit offers variable shade control from DIN 8 to 13, making it versatile enough for a wide range of processes including Stick, TIG, and MIG welding. Operators can also fine-tune the lens response with variable sensitivity and delay settings, ensuring optimal performance whether working outdoors in sunlight or in low-light shop conditions.

Reliable Power and Specification

Reliability is paramount in MRO and construction operations. The VIKING 2x4C utilizes a dual-power system, combining solar cells with replaceable CR1025 batteries to ensure the lens is always ready to arc. With a TIG rating of 5 amps, it provides consistent switching even during low-amperage precision welding. The lens features two independent arc sensors to detect the arc instantly, protecting the user from flash. This cartridge is an essential upgrade for any fleet of passive welding helmets, improving operator safety and weld quality through superior visibility.
