KP2853-3 - Lincoln Electric VIKING 1840 Series Replacement ADF Cartridge Kit with 4C Technology

Advanced Optical Performance for VIKING 1840 Helmets

The Lincoln Electric KP2853-3 VIKING 1840 Series ADF Cartridge Kit is a premium replacement component designed to restore and enhance the performance of your VIKING 1840 Series welding helmet. This kit is not merely a spare part; it is an upgrade that integrates Lincoln Electric's cutting-edge 4C Lens Technology. This proprietary technology filters out the traditional lime-green tint found in older auto-darkening filters, providing a view that is closer to natural light. This results in better color perception, reduced eye strain, and improved control over the weld puddle.

Engineered for precision, this ADF cartridge boasts a perfect 1/1/1/1 optical clarity rating. This rating, determined by European Standard EN379, evaluates the lens on four critical parameters: optical class, diffusion of light, variation of luminous transmittance, and angle dependence. Achieving a '1' in all categories ensures that the welder experiences minimal distortion, uniform shading across the entire viewing area, and a crisp image regardless of the viewing angle. This level of clarity is essential for high-precision fabrication where every detail matters.

The KP2853-3 is designed with user convenience in mind. It features external shade control, allowing operators to adjust the darkness of the lens without having to remove the helmet or lift the hood. This feature significantly improves workflow efficiency, especially in environments with varying lighting conditions or when switching between different welding processes. The cartridge is a direct fit for the 1840 Series shell, ensuring a secure seal and maintaining the safety integrity of the helmet.

Whether replacing a damaged unit or upgrading an older model, the KP2853-3 ensures that your personal protective equipment operates at peak performance. It supports the rigorous demands of industrial environments, including heavy fabrication, shipbuilding, and structural welding, by providing the visual acuity necessary for safe and effective work.
