ABSTRACT:
A method and apparatus for fusion joining polyethylene pipe. A power source supplies an input power to an input of a power supply. The input power has generally constant current and is converted to an output power at a relatively high frequency. The relatively high frequency output power is delivered to an installation tool. The output power delivered to the installation tool is controlled. The output power can be controlled as a function of ambient temperature surrounding the installation tool.
