S240-11 - Walter ArcOne Singles HD 2x4 Auto-Darkening Retrofit Lens Shade 11

High-Definition Clarity for Professional Welders

The Walter S240-11 Singles® HD Auto-Darkening Lens represents the pinnacle of retrofit welding technology. Designed to fit into standard 2" x 4-1/4" welding helmets, this lens allows welders to upgrade their existing passive hoods with modern auto-darkening capabilities. The unit features a fixed Shade 11 dark state, making it ideal for a wide range of amperage applications in MIG and Stick welding. By maintaining a consistent shade, the lens ensures reliable protection against harmful UV and IR radiation while the arc is active.

What sets the S240-11 apart is its High-Definition (HD) technology. Unlike older auto-darkening filters that may have a greenish or cloudy tint, the Singles® HD lens offers unparalleled optical clarity. This enhanced visibility allows the welder to see the weld puddle with greater definition, leading to more precise bead placement and higher quality welds. The lens operates with a light state of 2.5, which is significantly clearer than the standard shade 3 or 4 found in many competitors. This ultra-clear state facilitates easy viewing of the workpiece during setup and inspection without the need to lift the helmet.

Reliability is key in industrial environments, and the S240-11 delivers with dual arc sensors and solar-powered operation. The sensors detect the arc instantly, triggering the lens to darken in a fraction of a second. Because it is solar-powered, there are no batteries to replace or recharge, ensuring the lens is always ready when you are. The unit is built to meet rigorous safety standards, including ANSI Z87 and CSA Z94.3, and is backed by a comprehensive 3-year warranty, providing peace of mind for professional users.
