KP4003-1 - Lincoln Electric VIKING 4x5 Shade 11 Glass Filter Plate

Crystal Clear Vision for Precision Welds

When you are under the hood, the quality of your view dictates the quality of your weld. The Lincoln Electric KP4003-1 Shade 11 Glass Filter Plate is designed to give you that crisp, high-definition view of the puddle that only real glass can provide. While auto-darkening lenses are great for tacking and variable work, many professional welders still prefer the reliability and superior optical clarity of a traditional passive glass lens. This 4-inch by 5-inch plate offers a generous viewing area, allowing you to see not just the arc, but the joint ahead and the finished bead behind, ensuring you stay on track and maintain consistent travel speed.

This replacement lens is specifically built for the VIKING™ Industrial Passive™ helmet (K3371-1), making it the perfect upgrade or replacement for a scratched or pitted original plate. The Shade 11 tint is a versatile middle-ground darkness, perfect for most general fabrication, structural steel, and maintenance welding tasks. It blocks out harmful UV and IR rays effectively while letting you see the details of the molten pool without straining your eyes. Because it is made of glass, it resists scratching better than plastic lenses, meaning it stays clearer for longer, even in dusty shop environments. However, remember to always sandwich it between clear polycarbonate cover lenses to protect it from breaking.

Don't compromise on your eye protection or your work quality. A fresh lens can make a world of difference in reducing eye strain at the end of a long shift. Whether you are burning rod on a construction site or running flux-core in the shop, the KP4003-1 ensures your eyes are protected according to ANSI Z87.1 standards. It’s an affordable, essential spare to keep in your tool bag so you are never caught with a damaged lens that halts your production. Swap out your old, hazy filter for this genuine Lincoln Electric glass plate and see the difference immediately.
