The Hobart 770961 FS-11 Auto-Darkening Lens Assembly is a robust optical solution designed to upgrade standard passive welding helmets to modern auto-darkening technology. Engineered to fit the industry-standard 2-inch by 4-1/4-inch retention systems, this lens assembly is compatible with a wide array of welding hoods, including traditional "pipeliner" styles and pancake hoods often used in field construction and fabrication. The unit operates on a fixed shade system, providing a consistent Shade 11 darkness level when the arc is struck, which is suitable for a broad range of amperage applications in Stick (SMAW) and MIG (GMAW) welding.
Technically, the FS-11 utilizes high-quality liquid crystal technology to switch from a light state of Shade 3 to a dark state of Shade 11 in approximately 1/3600 of a second. This rapid reaction time ensures immediate eye protection from harmful UV and IR radiation upon arc ignition, minimizing operator fatigue and the risk of arc flash. The light state of Shade 3 offers excellent optical clarity, allowing operators to perform setup tasks, inspect welds, and reposition workpieces without the need to constantly raise the welding hood. This efficiency gain translates to higher productivity and improved safety compliance in busy industrial environments.
The assembly is fully solar-powered, eliminating the logistical burden of battery replacement and maintenance. It features two independent arc sensors that provide reliable detection even in obstructed or out-of-position welding scenarios. The lens is encased in a durable housing designed to resist moisture and dust, ensuring longevity in harsh MRO and construction settings. Compliant with ANSI Z87.1 safety standards, the Hobart FS-11 represents a cost-effective and reliable upgrade for fleet equipment, ensuring welders have access to modern protection technology without the expense of replacing entire helmet assemblies.
