Plain and simple. The whole point is to stop edge chipping and cut down on wasted material. This isn&rsquo;t about warming a room. It&rsquo;s about hitting the exact spot where the score line will go, with the right heat, fast. So the glass breaks clean, every single time.</p> <h2 id="the-nitty-gritty-power-voltage-and-shape">The Nitty-Gritty: Power, Voltage, and Shape</h2> <p>These tubes are all about packing a lot of heat into a small space. A typical unit runs at 2500W, on a 400V supply. That voltage choice is smart. It keeps the current lower, which means you can use <a href="https://henruite.com">thinner</a> wiring and not worry about voltage dropping off over long runs. The power is concentrated into a compact tube, so you can get the heat source right where you need it—close to the glass—without having to tear <a href="https://o-yate.com">apart</a> your whole machine. And the length of the tube? Not random. A 300mm tube, for example, gives you a predictable heating zone. Match that zone to the glass thickness and the scoring setup, and you get even preheating with no hot spots. Just steady, repeatable heat, every time.</p>
