The PRO-SAFE ADF820FF is an auto-darkening replacement lens designed for use in compatible welding helmets. Measuring 4.6 inches wide by 5.35 inches high and 0.47 inches thick, this clear-state lens provides a wide viewing window for welding professionals who need reliable arc protection and unobstructed sight lines. The lens meets ANSI Z87.1 standards, making it suitable for professional welding environments where eye protection compliance is required. It is installed by welders and fabricators as a direct replacement in supported helmet shells.
This auto-darkening lens is intended for use as a replacement component in welding helmets requiring a 4.6 x 5.35 inch format. It fits the 320-AD, WH-320-AD-SKL, and WH-320-AD-EGL helmet models. The clear base state allows for easy pre-weld positioning, while the auto-darkening function activates on arc strike to protect the welder's eyes from harmful UV and IR radiation. Typical applications include MIG, TIG, and stick welding in both shop and field settings.
Designed for use with the following helmet models: 320-AD, WH-320-AD-SKL, and WH-320-AD-EGL.
Installation is performed by the welder or equipment technician with the helmet fully powered down and arc operations ceased. The lens cartridge should be seated securely in the helmet frame before resuming work. Handle the lens by its edges to avoid contaminating the optical surface. Verify the replacement lens meets the shade and optical class requirements of the applicable ANSI Z87.1 standard before returning the helmet to service.
