We built it to pack a serious punch into a small space. Running it at 400V is a smart move. It pulls less current than those lower-voltage options, which means you can get away with smaller wires. The whole wiring job gets a lot simpler. At 300mm long, it focuses that 2500W of power right where you need it. You get a steady, predictable heat profile, which is perfect for jobs that demand precise temperature control. And it heats up fast. Seriously fast. But here&rsquo;s the catch: that kind of power density needs proper airflow or a good heat sink. You have to keep the surrounding electronics and mechanics from getting too toasty.</p>
