S240-8 - ArcOne Singles 2x4 Auto-Darkening Lens Shade 8 HD

ArcOne Singles S240-8 Auto-Darkening Filter Overview

The ArcOne S240-8 Singles is a specialized auto-darkening filter (ADF) designed to fit into standard 2-inch by 4.25-inch lens openings. This unit is part of the renowned Singles series, which provides welders with an economical and high-performance alternative to traditional passive glass lenses. The S240-8 is engineered with a fixed Shade 8 dark state, making it particularly suitable for low-amperage welding processes such as micro-TIG or light-duty MIG applications where visibility is critical and a standard Shade 10 or 11 would be too opaque.

One of the standout features of this filter is its High Definition (HD) technology. Unlike older ADFs that may have a greenish or muddy tint, the HD technology in the S240 series ensures a clearer, more natural view of the arc and the weld puddle. This optical clarity helps reduce eye strain over long shifts and allows for greater precision in bead placement. The lens operates with a light state of Shade 3, providing excellent visibility for setup, fit-up, and grinding tasks without the need to constantly flip the helmet up.

Technically, the S240-8 is robust and maintenance-free. It utilizes solar power technology, drawing energy from the welding arc itself and ambient light, thereby eliminating the need for battery replacements or charging. It is equipped with two independent sensors that ensure rapid detection of the arc, with a switching speed sufficient to protect the welder's eyes from flash. The unit is water and dust resistant, designed to withstand the harsh environments typical of industrial welding sites. It is a drop-in solution for most "Pipeliner" style helmets and "Pancake" hoods, offering modern protection in a classic form factor.

By integrating the S240-8 into their gear, professionals gain the productivity benefits of an auto-darkening lens—such as keeping the hood down between welds—while maintaining the lightweight and compact profile of their preferred 2x4 helmet. This specific model's Shade 8 rating fills a crucial niche for precision welders who require lighter shading for optimal control.
