B771R020 - Bulk Pack Outer Cover Lenses - 50 Count

Keep Your View Clear and Your ADF Safe

Every welder knows that if you can't see the puddle, you can't lay a good bead. The B771R020 BT Outer Lens is your best friend when it comes to keeping your vision sharp and your welds on point. We've all been there—trying to squeeze a few more days out of a pitted, smoked-up cover lens, squinting to see the joint. It’s not worth the headache or the bad welds. With this 50-pack of replacement outer lenses, you can swap out that dirty plate the second it starts to get hazy, ensuring you always have a crystal-clear view of your arc.

Your welding hood is an investment, and the Auto-Darkening Filter (ADF) is the heart of it. One piece of hot slag or a heavy spatter ball hitting your unprotected ADF can cost you hundreds of dollars in repairs or replacement. These polycarbonate outer lenses act as a sacrificial shield, taking the beating so your expensive electronics don't have to. They are built tough to resist heat and impact, giving you the confidence to get in close and weld without worrying about damaging your gear. The material is durable enough to wipe down, but cheap enough to toss when it gets too scratched up.

Buying in bulk just makes sense. Running out of cover lenses in the middle of a job is a rookie move that stops production dead in its tracks. With 50 lenses in a pack, you can stock your tool crib, your truck, or your personal gang box and be set for months. This pack is perfect for busy shops where multiple welders are burning wire all day long. The convenience of having a fresh stack of lenses means you are more likely to change them when needed, rather than pushing through with poor visibility.

Installation is a breeze. These lenses are designed to snap or slide into place quickly, so you aren't fumbling around with your hood while the rest of the crew is working. Just pop out the old, pitted lens, slide in a fresh B771R020, and you are back under the hood with a high-definition view. Whether you are doing heavy structural steel, delicate TIG work, or dirty flux-core welding, keeping a fresh outer lens on your helmet is the easiest way to improve your comfort and your weld quality immediately.
