Provided is an energizing heating and welding device for a deflection coil, which can be carried out while maintaining the reliability of the device. After rectifying the alternating current from the outside into the direct current with the rectifier 2, the inverter circuit 4 converts the pulse current into a pulse wave current, which is selectively turned on by the switches 25 and 26 by the switching circuit 27. By switching off, it is matched with the high frequency insulation transformer 9, and it is step-down by the high frequency insulation transformer 10, and is supplied to the welding circuit 14 by stepping down.
