The filter automatically transitions from a light state to a darkened shade when an arc is struck, protecting the welder's eyes from harmful radiation and UV exposure. Installed by welding professionals in fabrication shops, manufacturing environments, and field welding applications, the K590 provides a reliable lens solution for those who require fast, automatic shade response without manually flipping a fixed-shade lens. The unit weighs 1.5 pounds and is sold individually.\u003c\/p\u003e\u003cp\u003eThe K590 filter is suited for professional welders and fabricators working across a range of welding processes, including MIG, TIG, and stick welding. The auto-darkening function allows continuous visibility of the workpiece before the arc starts and reacts quickly once welding begins, reducing eye fatigue during extended work sessions. It is intended as a replacement or upgrade filter for compatible welding helmets that accept the Nova-series filter format.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAuto-darkening lens transitions automatically when arc is detected\u003c\/li\u003e\n\u003cli\u003eProtects against UV and infrared radiation during welding operations\u003c\/li\u003e\n\u003cli\u003eSold as a single unit for direct replacement or upgrade applications\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 1.5 pounds for reduced helmet fatigue\u003c\/li\u003e\n\u003cli\u003eDesigned for use across common welding processes including MIG, TIG, and stick\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement auto-darkening filter for welding helmets compatible with the Nova-series filter format.

Ensure the welding helmet is fully powered off and any battery or solar cell connections are clear before removing or installing the filter lens. Follow ANSI Z87.1 eye and face protection guidelines and the helmet manufacturer's instructions when seating the filter to ensure a proper seal and secure fit. Do not operate welding equipment until the filter is fully secured and the helmet has been inspected for light leakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OPTREL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OPTREL","offers":[{"title":"Default Title","offer_id":51347708313906,"sku":"K590","price":170.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310537728.jpg?v=1782111706","url":"https:\/\/voomisupply.com\/products\/optrel-k590-auto-darkening-welding-filter","provider":"Voomi Supply","version":"1.0","type":"link"}
