Getting Your Voltage Right for Glass Score Line Heating

When you’re heating a score line in glass, it’s all about a delicate balance. You need enough heat to weaken the glass exactly where you want it, but not so much that the whole thing just shatters. That’s why we use infrared quartz lamps. But here’s the real headache: the power grid.

The Voltage Struggle

Most lamps you find in a catalog are built for 110V or 220V. That’s fine for a home workshop, but not for a factory floor running on 480V or 575V. Now, you could slap a transformer on every single lamp to step the power down. But that’s a mess. It makes your machine bulky, takes up way too much space, and gives you a dozen more parts that can break. We do things differently. We actually build the lamps to match your power. By tweaking the thickness and length of the tungsten filament, we can hit whatever wattage you need—500W, 2000W, whatever—while running directly on your industrial voltage. You just wire them straight into your busbars and forget about it.
