If you’ve ever tried to cut through ultra-thick glass, you know the struggle. A sharp blade isn’t enough. You can have the best wheel in the world, but if the glass is fighting you, you’re going to have a bad time. The secret is changing how the glass behaves before the wheel even touches it. We use short-wave infrared (SWIR) heating tubes for this. Most heaters just warm up the surface—kind of like a heating pad—but SWIR is different. It actually sinks deep into the glass. Here is why that matters. Standard heaters mostly just bounce off the surface of thick glass. But SWIR tubes hit that sweet spot (between 0.7 and 2.5 microns), which lets the heat soak right into the path you’re about to cut. It softens the glass along that score line. Suddenly, the wheel isn’t fighting a brick wall; it’s gliding. And your tools will thank you. Cutting cold, thick glass is brutal on your equipment. You can practically hear the diamond or carbide edges chipping away. It’s loud, it’s stressful, and you end up swapping out expensive consumables way too often. When you pre-heat the path, the friction disappears. The wheel just slides through. Your tools last longer, and you spend less time stopping the line to fix things. Now, there are a few things to watch out for. To get that deep heat, we have to run these tubes at high power. It means they ramp up fast, which is great, but it puts a real strain on your power supply. You’ll want to double-check that your wiring can handle the current, or you’ll run into voltage drops. Also, this stuff getshot. Really hot. If you don’t use heat shields or get some decent airflow going, you might find your aluminum framing starting to warp. The good news? These tubes are pretty easy to set up. They’re designed to slide right into your existing IR arrays. We spend a lot of time dialing in the focal length so the heat hits exactly where the cut happens. The result is a score line that’s nice and hot, while the rest of the plate stays cool. It’s the best of both worlds.
