GP4 - 4-1/2 x 5-1/4 Inch Heat Treated Glass Welding Lens Filter Plate

See the Puddle Clearly with Real Glass

There is a reason many seasoned welders still swear by glass lenses: the clarity is simply unmatched. If you are tired of squinting through scratched, hazy plastic lenses, the GP4 Heat Treated Glass Lens Filter Plate is the upgrade your hood needs. Sized at 4-1/2" x 5-1/4", this lens drops right into your standard large-view fixed-shade helmet, bringing back the crisp, high-definition view of the arc that helps you lay down perfect beads every time. Plastic lenses might be lighter, but they just can't compete with the optical quality of genuine glass.

We know that the shop environment is tough on gear. Spatter, grinding dust, and heat take a toll on everything. That is why this lens is heat-treated. It is hardened to handle the thermal shock of heavy welding and is far more resistant to pitting than plastic. When spatter hits a plastic lens, it often melts in and ruins it. With this glass plate, spatter is less likely to stick, and the surface resists the fine scratches from wiping off dust that eventually turn plastic lenses cloudy. This means you spend less money on replacements and more time under the hood.

Whether you are TIG welding and need to see the finest details of the puddle, or you are burning heavy flux-core and need a lens that won't warp from the heat, this glass filter plate delivers. It cleans up easily and stays clear longer. Give your eyes a break and get back to the basics with a lens that works as hard as you do. It’s a simple, effective upgrade for any welder who values their vision and their work quality.
