A carpet seaming iron having an internal electronic temperature control circuit including a solid state temperature sensor, a power controller, and a solid state switching device is disclosed. The iron does not use a thermostat for temperature control. The iron includes a baseplate, an electrically powered heating element, a heat shield, a handle and the internally mounted control circuit.
