When you&rsquo;re annealing it, you have to pull the heat out just right. If the heating profile is too slow or uneven, the stress never really leaves. Then, when it cools, it cracks. So we built a mobile repair rig that can move with the job. But that meant finding power that&rsquo;s compact, reliable, and totally in control. You need a heating element that slips into tight corners, runs on limited voltage, and still gives you the steady, focused intensity to rework glass without creating new stress fractures.</p>
