Fixed-Shade ADF Lens for 2x4 Helmets
This Walter Surface Technologies S240-9 retrofit lens fits most 2 x 4 inch welding helmets. It provides a fixed shade 9 filter with HD technology for clear viewing. The auto-darkening filter removes the need to flip the helmet between welds.
For Single-Shade Workflows Only
Welders who use one consistent amperage range and prefer a set shade will find this lens practical. It is not suited for fabricators who frequently switch between low-amp TIG and high-amp MIG processes requiring variable shade adjustment.
2 x 4 Inch Retrofit Format
The lens measures 2 x 4 inches to match standard helmet apertures. Compatibility depends on the helmet accepting this exact footprint, so verify the opening before ordering.

Questions about this item
Will this 2 x 4 inch retrofit lens fit the older helmet I already own?
The lens is designed to retrofit most welding helmets that accept a 2 x 4 inch filter, so it should install directly into your existing helmet.
How can I confirm the lens is working correctly after installation?
The lens provides a fixed shade 9 filter; once fitted, the viewing area should maintain a consistent shade 9 darkness during use.
Does the package include any mounting hardware or only the lens itself?
The product is supplied as the retrofit ADF welding lens only; no additional mounting hardware or accessories are listed.
