<p>A deflecting coil winder provided with a heating device for soldering electrodes to leads sections at both ends of a deflecting coil and for shaping and fixing the deflecting coil by a single device and which can control the voltage, current, and power to be applied to the heating device in a wide range and precise level. AC current from outside to the heating device is rectified to DC current by a rectifier (102) and then is converted by pulse wave current by an inverter (104). The pulse wave current is boosted by a high-frequency insulation transformer (109) and then is supplied to a heating device (113) by switching elements (125, 126) in a switching circuit (127). When the switching element (125) is closed, the pulse wave current is boosted by the high-frequency insulation transformer (110) and is supplied to a heating circuit (113). When the switching element (126) is closed, the pulse wave is stepped down for supplying the power to the welding circuit (114).</p> |
