Product Overview

The Miller FS-11 Auto-Darkening Welding Lens (SKU: 287833) represents a significant optical upgrade for welders utilizing standard passive helmets. Engineered to fit the industry-standard 2-inch by 4.25-inch lens opening, this unit allows operators to modernize existing equipment with advanced auto-darkening capabilities without replacing the entire helmet shell. The lens is distinguished by Miller's proprietary ClearLight™ Lens Technology, which optimizes contrast and clarity in both welding and light states, providing a 3.0 light state for clear visibility during setup and inspection.

Technical Specifications

This fixed-shade model operates at a dark state of Shade 11, suitable for a wide range of general welding applications. It features a switching speed of 1/3,600 of a second, ensuring immediate protection upon arc initiation. The unit is equipped with two independent arc sensors and is fully solar-powered, utilizing the welding arc and ambient light to charge, thereby eliminating the maintenance requirement of battery replacement. The viewing field measures 3.70 x 1.37 inches (approximately 5.07 square inches), offering a substantial view of the workpiece.

Compatibility and Standards

The FS-11 is designed for broad compatibility, fitting most major brands of welding helmets that accept a standard 2x4 retaining system. It meets ANSI Z87.1 and CSA Z94.3 safety standards, ensuring compliance with industrial safety regulations. While robust for most processes, it has a low-amperage TIG rating of 20 amps; for applications below this threshold, alternative specialized lenses may be required. The product is backed by Miller's 3-year warranty, underscoring its durability and reliability in industrial environments.
