Abstract:
A method for creating an electrofusion between a plurality of thermoplastic members, wherein at least one of the members has an electrically resistive element embedded therein, the method comprising the steps of:providing a self contained, easy-to-use device in an enclosure comprising a battery pack, alternating current generator, voltage control and multiple output lines for connection to the electrically resistive element; generating an alternating current voltage from a direct current power supply by direct electronic conversion of direct current from the direct current power supply into alternating current; separately controlling by a programmable electronic data processing means, the polarity, level and frequency of the voltage and current in each of the output lines at a predetermined level to create an alternating current output; and transmitting the predetermined alternating current output to the electrically resistive element.
