Measuring 4.5 inches by 5.25 inches, this filter plate fits standard welding helmets and hand shields that accept this lens size. It carries a Shade 9 rating, making it appropriate for lower-amperage arc welding processes where a moderate level of light attenuation is required. The heat-treated glass construction provides durability and optical clarity under sustained welding conditions. Licensed welders and fabricators typically select this lens based on shade number and physical dimensions to match their existing headgear.\u003c\/p\u003e\n\u003cp\u003eThis filter plate is suited for professional and light industrial welding applications including MIG, TIG, and stick welding at amperage ranges consistent with a Shade 9 rating. It is commonly installed in welding helmets, flip-front shields, and goggles that accept 4.5 inch by 5.25 inch rectangular lens inserts. Fabrication shops, maintenance welders, and field welding crews use this style of filter plate as a replacement or spare lens. The lens ships as a single unit and is intended for direct installation into compatible lens frames without further modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eShade 9 optical density for arc welding eye protection at moderate amperage levels\u003c\/li\u003e\n  \u003cli\u003eHeat-treated glass construction for durability and resistance to weld spatter heat\u003c\/li\u003e\n  \u003cli\u003eStandard 4.5 inches x 5.25 inches rectangular format fits a wide range of helmet and shield frames\u003c\/li\u003e\n  \u003cli\u003eFilters ultraviolet and infrared radiation generated during arc welding\u003c\/li\u003e\n  \u003cli\u003eSold individually for single-lens replacement or backup use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement filter plate for welding helmets, hand shields, and goggle frames that accept a 4.5 inch by 5.25 inch rectangular glass lens insert with a Shade 9 rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFilter plate installation is performed by qualified welders or equipment maintenance personnel. Before replacing a lens, ensure the welding machine is powered off and the work area is clear of arc flash hazards. The lens should be seated securely in the helmet or shield retaining frame with no gaps at the edges that could allow unfiltered light to pass. Always verify the installed shade number meets ANSI Z87.1 requirements for the specific welding process and amperage being used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShade Number\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLens Dimensions\u003c\/strong\u003e: 4.5 inches x 5.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Heat-treated glass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DYNAFLUX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UV4509GF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DYNAFLUX","offers":[{"title":"Default Title","offer_id":51342791737650,"sku":"UV4509GF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310495211.jpg?v=1782006781","url":"https:\/\/voomisupply.com\/products\/dynaflux-uv4509gf-glass-filter-plate-shade-9-welding-lens","provider":"Voomi Supply","version":"1.0","type":"link"}
