A multi-speed lightweight gutter machine includes a lightweight aluminum frame having hollow structural members. Each forming stage includes structural support members, flintstone transfer rollers, and at least some forming stages have forming wheels composed of lightweight plastic to further reduce the weight of the machine. The machine includes an inverter unit that converts single-phase power into three-phase power, a three-phase electric motor, and a variable frequency drive unit that controls the speed of the motor by controlling the frequency of the three-phase power applied to the motor. A controller unit commands the variable frequency drive unit to a user-selected speed. Wiring for electrical components is primarily routed within the interior of the hollow structural members of the lightweight aluminum frame to enhance safety. A transparent protective cover protects the interior of the machine while providing visibility to the operator.
