3M Speedglas 9100X Inside Cover Lens (5-Pack)

Clear Vision Means Better Welds: Speedglas 9100X Inside Lens Replacement

You invested in a Speedglas 9100X for its top-tier clarity and wide viewing area, so why let a scratched or foggy inside lens ruin the view? The Inside Protection Plate (06-0200-30) is the unsung hero of your welding hood. While the outside lens takes the beating from sparks and spatter, the inside lens fights a different battle: sweat, breath condensation, and the inevitable scratches from wiping it down with a dirty glove or shop rag. Once that inside lens gets hazy or pitted, your expensive high-definition view turns into a blurry mess, leading to eye strain and wandering welds.

This 5-pack of replacement plates is the cheapest insurance you can buy for your eyes and your equipment. Swapping them out is incredibly simple—just flex the plate slightly to pop it out of the retention tabs and snap a new one in. No screwdrivers, no hassle. Within seconds, you restore that "brand new helmet" feeling. It is crucial to remember that this specific plate fits the 9100X filter only (the "Extra Large" view). If you have the standard 9100V or the double-wide 9100XX, you'll need different part numbers, so check your ADF model before ordering.

Don't risk damaging the actual glass of your auto-darkening filter. If you run without this plate, or with a cracked one, you expose the sensitive electronics to moisture and grime. A ruined ADF costs hundreds of dollars to replace; a new inside plate costs pennies by comparison. Keep a pack in your toolbox or locker. When you can't see the puddle definition or the toe of the weld clearly, don't blame the machine—check your inside lens. A fresh plate clears up the fog and lets you get back to laying perfect beads.
