Getting Your Voltage Right for Glass Cutting

If you’ve ever worked with thermal stress cutting, you know it’s all about that perfect temperature gap across the glass. You need a very specific amount of heat to get that clean, satisfying snap. If your infrared (IR) lamp isn’t hitting its rated wattage, you’re just guessing. And that’s where the voltage headache starts.

Why Voltage Actually Matters

Here is the thing: our IR lamps are picky about their electrical load. Imagine you take a lamp built for 230V and plug it into a 110V circuit. You aren’t just losing a little bit of heat—you’re losing about 75% of your power. The glass never gets hot enough to snap, and you end up with a pile of wasted material. On the flip side, if you push too much voltage through a lamp? You’ll pop the filament almost instantly.Pop. Gone. To stop that from happening, we offer custom windings for 110V, 480V, and 575V. You’ll see those higher voltages a lot in big industrial plants. They use them to keep the current draw low, which means they can use thinner wires over long distances without the power dropping off by the time it reaches the machine.
