Retrofit ADF Lens Shade 11&12

This new Walter Surface Technologies S240 retrofit lens converts most 2 x 4 welding helmets to an auto-darkening system. It provides two selectable dark shades, 11 and 12, plus a dedicated grind mode for preparation work. The single unit fits a wide range of existing helmet shells without modification.

Welders needing variable shade and grind function

The lens suits welders who switch between processes requiring shade 11 or 12 and want a built-in grind setting without swapping plates. It is not for operators who need shade levels outside the 11 to 12 range or who require a larger viewing area than the standard 2 x 4 window provides.

Dual shade 11 and 12 with grind mode

The decisive specification is the combination of two fixed dark shades, 11 and 12, and a separate grind mode in one retrofit cartridge. If your application demands a different shade spread or a single fixed shade, this lens will not match the requirement.

Questions about this item

Will the S240 retrofit lens fit my existing 2 x 4 welding helmet?

Yes, the lens is designed to retrofit most 2 x 4 welding helmets, so it should fit standard openings of that size.

Can I use the S240 lens for grinding as well as Shade 11 and 12 welding?

The lens includes a grind mode that keeps the view light, allowing you to grind without swapping the filter.

How do I confirm the S240 lens is functioning correctly after installation?

Power the unit, select Shade 11 or 12, expose the sensor to the welding light, and verify the filter darkens to the chosen shade; then switch to grind mode and confirm the view remains light.
