Abstract
A fusion joining apparatus includes an electrical power source, a first frequency converter coupled to the electrical power source, a connector for connection to an induction fusion heater, a second frequency converter and a controller. During operation, the electrical power source generates source electrical power at a source voltage and a source frequency. The first frequency converter steps up the voltage and the frequency of the source electrical power to produce high voltage electrical power. The second frequency converter reduces the voltage and frequency of the high voltage electrical power and produces low voltage electrical power. The second frequency converter has terminals for connection to a resistance fusion heater to provide the low voltage electrical power to the resistance fusion heater. The controller includes a processor which selects one of the second frequency converter and the connector and a switch to direct the high voltage electrical power to the selected one of the second frequency converter and the connector.
