AROS240-10 - ArcOne S240-10 Singles 2x4 Auto-Darkening Filter Shade 10

Technical Overview of the ArcOne S240-10

The ArcOne S240-10 is a specialized auto-darkening filter (ADF) designed to retrofit standard passive welding helmets that utilize a 2-inch by 4.25-inch retaining system. Part of the ArcOne "Singles" series, this cartridge offers a streamlined, economical solution for welders seeking the efficiency of auto-darkening technology without the need to purchase a completely new helmet assembly. The unit features a fixed Shade 10 dark state, which is the industry standard for a wide variety of general welding applications, including Stick (SMAW) and MIG (GMAW) processes within standard amperage ranges.

Technically, the S240-10 is engineered with two independent arc sensors located on the face of the cartridge. These sensors detect the welding arc initiation and trigger the liquid crystal display (LCD) to switch from a light state of Shade 3 to the dark state of Shade 10 in approximately 0.5 milliseconds. The light state of Shade 3 provides sufficient visibility for material setup, grinding, and torch positioning, significantly reducing the need for the operator to constantly raise and lower the helmet assembly. This reduction in repetitive movement contributes to lower fatigue and increased productivity over long shifts.

The power management system of the S240-10 is entirely solar-driven. It does not require replaceable batteries or external charging, relying instead on the UV/IR emissions from the welding arc and ambient light to maintain the charge of its internal capacitor. This design ensures the unit is always ready for use and eliminates downtime associated with battery failure. The cartridge is built to withstand the harsh environment of industrial welding, offering resistance to dust and moisture ingress. It is compatible with most "Jackson Style" or "Pipeliner" style helmet shells that accept a standard 2x4.25 inch glass or polycarbonate filter plate.
