Optrel K590 Auto-darkening Welding Filter

Product Description

The OPTREL K590 is an auto-darkening filter designed for use in welding helmets and face shields. 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.

The 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.

Key Features

• Auto-darkening lens transitions automatically when arc is detected
• Protects against UV and infrared radiation during welding operations
• Sold as a single unit for direct replacement or upgrade applications
• Lightweight construction at 1.5 pounds for reduced helmet fatigue
• Designed for use across common welding processes including MIG, TIG, and stick

Compatibility

Designed as an OEM-style replacement auto-darkening filter for welding helmets compatible with the Nova-series filter format. Consult your helmet manufacturer documentation to confirm fitment before installation.

Installation Notes

Installation should be performed by a qualified welding professional familiar with personal protective equipment standards. 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.
