269505 - Miller Digital Performance Replacement Auto-Darkening Lens Assembly

Genuine Replacement Optics for Digital Performance Helmets

The Miller 269505 Lens Assembly is the direct OEM replacement Auto-Darkening Filter (ADF) designed specifically for the Digital Performance™ Series of welding helmets. As a critical component of personal protective equipment, this assembly restores the helmet's protective capabilities and optical performance to factory specifications. The unit is engineered to fit seamlessly into the existing retention system of Digital Performance shells, ensuring a secure fit and proper seal against spatter and fumes.

Technologically, this lens assembly features advanced digital circuitry that provides welders with precise control over their viewing environment. It utilizes three independent arc sensors to detect the welding arc instantly, triggering the liquid crystal display to darken in a fraction of a second. The digital interface allows for exact numerical settings for shade, sensitivity, and delay, eliminating the guesswork often associated with analog dials. This precision is essential for industrial environments where varying amperages and processes are used throughout the day.

The assembly supports multiple operational modes: Weld Mode (Shades 8-13) for general welding, Cut Mode (Shades 5-8) for plasma or oxy-fuel cutting, and Grind Mode (Shade 3) for material preparation. This versatility allows the operator to perform pre- and post-weld tasks without removing the helmet, thereby increasing productivity and safety compliance. The unit is powered by replaceable CR2450 lithium batteries with solar assist, ensuring long operational life and reliability.
