3M Speedglas 9100XXi Replacement Auto-Darkening Lens Filter

See the Difference with True-View

Stop welding in a green haze. The Speedglas 9100XXi Auto-Darkening Filter changes the game with 3M's Natural Color Technology. This lens allows you to see your weld puddle, the joint, and your surroundings with greater contrast and realistic color. Whether you are laying down precision TIG beads or burning heavy flux-core, the clarity provided by the 9100XXi helps you read the arc better, leading to higher quality welds and less eye strain at the end of the shift.

Instant-On and Memory Modes

Time is money, and the 9100XXi is built for efficiency. The "Grab-and-Go" motion sensor means you never have to remember to turn your helmet on; just pick it up, and it's ready to weld. If you pair this lens with the 9100XXi Silver Front Panel, you unlock external controls that let you switch to Grind Mode with a simple tap of a gloved hand—no more flipping up the hood or taking off your gloves to adjust settings. You can also save your two most-used settings and toggle between them instantly.

Massive Viewing Area

The "XX" in 9100XXi stands for extra-extra large. With a 2.8" x 4.2" viewing window, you get a panoramic view of your workpiece. This peripheral awareness is critical for safety and comfort, reducing the need to constantly move your head to track the weld. The lens offers a versatile shade range (5, 8, 9-13), making it suitable for virtually any process, from low-amp micro-TIG to high-amperage plasma cutting.
