Rated at Shade 11, this lens is suited for medium to heavy welding processes including MIG and TIG welding where higher amperage arcs are common. The lens measures 4.25 inches wide by 2 inches high, fitting standard welding helmet and hand shield filter frames that accept this common rectangular format. It meets ANSI Z87.1 requirements for occupational eye and face protection, making it compliant for job site use. Weighing approximately 0.097 pounds, it is a lightweight direct drop-in replacement for worn or damaged filter plates.

This fixed shade lens is used in industrial and fabrication environments, shipyards, construction sites, and shop settings where arc welding is performed. It is installed in welding helmets and hand-held welding shields that accept a 4.25 inch by 2 inch filter plate opening. Shade 11 is appropriate for welding processes conducted at moderate to high amperage ranges. Welding professionals, pipefitters, ironworkers, and maintenance technicians working with MIG or TIG equipment at typical production amperage levels are the primary users of this lens grade.

Installation Notes

This lens is installed by welding professionals or safety equipment technicians performing helmet maintenance. Before replacing the lens, ensure the welding helmet is off the operator and the work area power source is off. The fixed shade lens slides or snaps into the helmet filter frame retainer; no tools are typically required. Verify the lens seats flush with no gaps before returning the helmet to service, and inspect the retainer clips or frame for wear that could allow the lens to dislodge during use.
