The DYNAFLUX UVGO4512PF is a gold-tinted polycarbonate filter plate designed for use in welding helmets and goggle frames that accept a 4.5 inch x 5.25 inch lens. Made from 100% polycarbonate, this filter plate provides optical protection at Shade 12, a density appropriate for arc welding, MIG, TIG, and similar high-intensity processes. The lens material offers impact resistance alongside the required optical filtering. These filter plates are installed by welders, fabricators, and industrial maintenance technicians who need a reliable replacement or spare lens for their existing headgear.
Shade 12 filter plates are suited for moderate- to high-amperage arc welding applications where adequate darkening is required to protect the operator's eyes from infrared and ultraviolet radiation. This plate fits standard goggle and helmet frames that accept a 4.5 inch x 5.25 inch filter opening. It is a drop-in replacement for worn, scratched, or damaged lenses in the field or shop environment. Single-unit availability makes it practical for service technicians and job-site replenishment without requiring bulk purchases.
Designed as a replacement filter plate for welding helmets and goggle frames that accept a 4.5 inch x 5.25 inch lens insert at Shade 12.
Filter plate replacement is performed by welders and PPE-qualified technicians. Before replacing the lens, remove the headgear and ensure it is clear of the work area. The filter plate slides or snaps into the retaining frame; confirm the plate is fully seated and the retaining cover is secured before resuming work. Inspect the replacement lens for surface damage before installation, as cracks or chips compromise optical protection.
