Pro-safe 4x5SF12 Fixed Shade Welding Lens Shade 12

Product Description

The PRO-SAFE 4x5SF12 is a fixed shade welding lens designed to protect welders' eyes from harmful arc radiation during welding operations. This lens carries a Shade 12 rating, making it appropriate for medium-to-high amperage welding processes where intense arc brightness demands dependable optical attenuation. Measuring 5.25 inches wide by 4.5 inches high, it fits standard welding helmets and goggles that accept this common filter plate size. The fixed shade design offers no adjustable tint, delivering consistent, reliable protection in every use. Compliance with ANSI Z87.1 confirms the lens meets established optical and impact-resistance requirements for industrial eye protection.

This fixed shade lens is suited for professional welding environments including fabrication shops, pipe welding, structural steel work, and MIG or stick welding applications where a Shade 12 filter is indicated. It is installed by welders, pipefitters, ironworkers, and other trade professionals who require certified eye protection during arc welding tasks. The lens drops into compatible helmet frames or goggles as a direct filter plate replacement, making field swaps straightforward during a job.

Installation Notes

Installation is performed by the welder or safety equipment technician before commencing any arc welding work. Ensure the helmet or goggle frame is fully powered down or de-energized if auto-darkening components are present before removing the existing lens. Seat the fixed shade lens securely in the filter plate retainer to prevent movement during use. Verify the installed lens shows no cracks, chips, or distortion before resuming welding operations.
