UML-100 - ArcOne +1.00 Universal Welding Cheater Lens

Clearer Puddle Control with the ArcOne Cheater Lens

Every welder knows that if you can't see the puddle, you can't make the weld. The ArcOne UML-100 is a +1.00 diopter magnifying lens—commonly known in the trade as a "cheater lens"—designed to bring your work back into focus. If you are finding yourself struggling to see the toe of the weld or distinguishing the slag from the molten pool, this drop-in lens is the industry-standard fix. It eliminates the hassle of wearing reading glasses under your hood, which can fog up, slip down, or cause discomfort against the helmet suspension.

This unit is built to the standard 2" x 4" dimensions, meaning it fits right into the cheater lens slot found on almost all Miller, Lincoln, ESAB, and generic welding hoods. It is compatible with both horizontal and vertical retention bars, so you don't have to worry about fitment issues. Simply pop out your retaining clip, slide this lens in behind your auto-darkening filter or passive shade, and lock it back down. It replaces the standard clear rear cover plate in some setups or sits in front of it in others, depending on your specific helmet's stack-up.

For TIG welders working on thin-gauge aluminum or stainless steel, the +1.00 magnification provides just enough zoom to keep a tight arc length without dipping your tungsten. For stick and MIG welders, it helps in reading the puddle dynamics more clearly, leading to straighter beads and better tie-ins. At just under 0.2 lbs, it won't throw off the balance of your hood. Stop straining your eyes and start laying down better beads with the optical clarity provided by ArcOne.

Whether you are an older welder whose eyes aren't what they used to be, or a young fabricator doing precision aerospace work, the UML-100 is a toolbag essential. It is a cost-effective way to upgrade your hood's performance instantly. Don't let poor vision compromise your weld quality; equip your helmet with the right optics for the job.
