KP3243-2 - Lincoln Viking 2450D Digital Replacement Auto-Darkening Filter

Restore Precision Vision with the KP3243-2 ADF Kit

The Lincoln Electric KP3243-2 VIKING 2450D ADF Replacement Kit is the definitive solution for maintaining the high-performance standards of your Viking 2450D welding helmet. As the core component of the helmet, the Auto-Darkening Filter (ADF) is responsible for both the safety of the operator and the quality of the weld visibility. This replacement kit is not merely a spare part; it is a technological refresh that ensures your equipment continues to deliver the 1/1/1/1 optical clarity that professional fabricators demand.

Central to this unit is Lincoln Electric's proprietary 4C Lens Technology. This advanced filtration system broadens the color range and hues that can be seen in both light and dark states. Unlike traditional auto-darkening lenses that often impart a lime-green tint, the 4C technology provides a true-color view. This reduction in eye strain is critical for long shifts, allowing for better control over the weld puddle and easier identification of the arc, puddle, and base material. The "4C" stands for Clarity, Color, Carat, and Cut, representing a holistic approach to lens quality.

The "D" in the 2450D series signifies its Digital Interface. This replacement ADF retains that sophisticated control mechanism, allowing welders to set shade, sensitivity, and delay with numerical precision rather than approximate analog dials. This is particularly useful in industrial environments where specific settings must be replicated for consistent results across different welding processes. The unit features four independent arc sensors, ensuring that the lens darkens instantly—within 1/25,000 of a second—even if one or two sensors are blocked by obstructions or awkward welding positions.

Designed specifically for the 2450D shell, this ADF offers a generous 9.3 square inch viewing area. It seamlessly integrates into the existing helmet assembly, maintaining the proper weight balance and seal against ambient light. Whether you are TIG welding at low amperages or performing heavy MIG fabrication, the variable shade range of 5-13 ensures optimal protection. By choosing the genuine KP3243-2, you ensure that your safety equipment remains compliant with ANSI and CSA standards while extending the service life of your premium welding hood.
