S240-10/11 - ArcOne Singles Duo 2x4 Auto-Darkening Filter Shade 10

High-Performance Optical Upgrade for Standard Helmets

The ArcOne S240-10/11 Single Duo 2x4 Shade 10 Auto-Darkening Filter represents a significant technological advancement in retro-fit welding optics. Designed to fit the industry-standard 2-inch by 4.25-inch lens retention systems found in many traditional welding helmets, such as the classic 'Pipeliner' style or pancake hoods, this filter allows operators to modernize their equipment without discarding their preferred headgear. The unit functions as a direct replacement for passive glass or polycarbonate filter plates, introducing the efficiency and safety of auto-darkening technology to established helmet platforms.

Technically, the S240-10/11 is engineered with two independent arc sensors located at the top of the cartridge. These sensors provide rapid detection of the welding arc, triggering the liquid crystal display (LCD) to transition from a clear state (Shade 3) to a dark state (Shade 10) in a fraction of a millisecond. The fixed Shade 10 opacity is calibrated to provide optimal protection for a wide range of amperage settings typically encountered in general fabrication, pipe welding, and maintenance repair operations. The light state of Shade 3 is sufficiently clear to allow welders to perform setup tasks, grind, or inspect fit-ups without raising the helmet, thereby maintaining continuous UV/IR protection and reducing the frequency of repetitive neck movements.

The optical quality of the ArcOne Singles line is a key differentiator. The filter utilizes High Definition technology to ensure a crisp, distortion-free view of the weld puddle. This clarity is essential for maintaining tight tolerances and achieving high-quality weld beads. Power management is handled efficiently through solar technology, which harvests energy from the welding arc and ambient light, eliminating the need for battery replacements and ensuring the unit is always ready for operation. The robust casing is designed to resist moisture and dust, ensuring longevity in harsh industrial environments.

By integrating the S240-10/11 into their personal protective equipment (PPE), industrial facilities and individual welders can expect improvements in workflow efficiency. The elimination of the 'helmet nod'—the physical motion required to lower a passive helmet—reduces neck strain and fatigue over long shifts. Furthermore, the consistent auto-darkening performance ensures that the welder's eyes are protected from the moment the arc is struck, mitigating the risk of arc flash associated with mistimed helmet drops.
