A butt fusion machine for joining of polyethylene pipe comprises a carriage assembly and a carriage controller disposed in the fusion machine. Programmed instructions stored in a non-volatile memory of the carriage controller control the carriage assembly for selectively operating in at least one of a manual, automatic, and semi-automatic mode of the butt fusion process. A butt fusion process, after a setup sequence includes (1) selecting a sequence of operating steps of a manual mode, an automatic mode, and a semi-automatic mode; and (2) executing the selected operating mode. The semi-automatic mode includes at least one step requiring intervention by an operator to confirm proceeding to a next step.
