KP3045-4 - Lincoln VIKING 3350 Gen 4 Replacement Auto-Darkening Filter Kit

Restore Peak Optical Performance

The Lincoln Electric VIKING 3350 Series ADF Cartridge Kit (KP3045-4) is the definitive replacement component for maintaining the high-performance standards of 4th Generation VIKING 3350 welding helmets. In the industrial welding sector, the integrity of personal protective equipment is paramount, not only for safety but for the quality of workmanship. This Auto-Darkening Filter (ADF) is engineered to deliver the same premium specifications as the original unit found in new Gen 4 helmets, ensuring that operators do not have to compromise on visibility or reaction time when a replacement is required.

At the core of this cartridge is Lincoln Electric's proprietary 4C Lens Technology. Unlike traditional ADFs that often impart a lime-green tint to the view, 4C technology filters light to provide a true-color view of the arc, puddle, and base material. This reduction in color saturation allows for better control over the weld bead and reduces eye strain during prolonged shifts. The cartridge boasts a perfect 1/1/1/1 optical clarity rating, measured against the EN379 standard. This signifies the highest possible score in four critical categories: optical quality (blurriness), diffusion of light (clarity), variation in luminous transmittance (uniformity of shade), and angular dependence (view form angles). Such precision is critical for structural welding and heavy fabrication where defect identification is essential.

Technically, the KP3045-4 is a powerhouse. It features a massive 12.5 square inch viewing area, one of the largest in its class, providing an expansive field of view that improves situational awareness and safety. The unit is equipped with four independent arc sensors that ensure reliable triggering even when the arc is partially obstructed, a common scenario in complex pipe or structural joints. With a switching speed of 1/25,000 of a second, the lens transitions from light to dark instantaneously, protecting the welder's eyes from harmful UV and IR radiation. Furthermore, the low TIG rating of 2 Amps demonstrates the sensitivity of the electronics, making it suitable for precision low-amperage TIG applications as well as heavy MIG and Stick welding.

This kit is specifically designed for compatibility with KXXXX-4 VIKING helmets. It is not backward compatible with older generations, ensuring that the advanced optics are paired with the correct shell geometry for optimal protection.
