Product identity

The Walter Surface Technologies S240-11 is a retrofit auto-darkening filter lens in shade 11, sized at 2 by 4 inches. It is designed to upgrade compatible welding helmets with automatic darkening technology. Welders seeking to modernise existing headgear will find this drop-in replacement matches the standard 2 x 4 form factor.

Fit and limitations

This lens suits welders who already own a helmet accepting 2 x 4 inch cartridges and want shade 11 protection. It does not suit users whose helmets require a different cartridge size or a variable shade range beyond the single fixed setting. Buyers needing multiple shade options or a larger viewing area should look at alternative products.

Deciding specification

The fixed shade level of 11 is the single specification that determines whether this lens matches the welding process and amperage in use. Confirm that your application calls for shade 11 before purchasing, as the filter cannot be adjusted to lighter or darker settings.
