OVERVIEW

See the Arc Like Never Before

Your vision is your most important tool, and when your helmet's lens is compromised, so is your weld. The Miller T94i Replacement Lens Assembly (278617) is the direct replacement for your T94i helmet, bringing back the crystal-clear view you rely on. If your original ADF has been damaged or is malfunctioning, this unit swaps in easily to get you back under the hood with zero downtime. It comes loaded with Miller's industry-leading ClearLight™ Lens Technology, which removes the artificial green tint found in older lenses, letting you see the true colors of the metal and the arc. This means better puddle control, easier joint tracking, and less eye strain at the end of a long shift.

Reliability in Any Environment
Frustrated by your lens flashing you when you're welding outdoors or working in tight corners? This lens features Miller's exclusive X-Mode™. Instead of just looking for the flash of light, X-Mode senses the electromagnetic field of the arc itself. This means your lens stays dark even in direct sunlight and won't flicker if your hands or fixtures block the sensors. It's rock-solid reliability that lets you focus entirely on the bead.

Customized Control
The digital controls are oversized and easy to navigate, allowing you to dial in your shade settings with half-shade precision. Whether you are TIG welding at low amps or running heavy flux-cored wire, you can adjust the sensitivity and delay to match your personal preference. Plus, with the built-in InfoTrack™ 2.0, you can keep a running tally of your arc time, helping you track your own efficiency or bid jobs more accurately. Don't settle for generic replacements; keep your T94i performing at its peak with the genuine Miller 278617 assembly.
