The heater unit 4 is heated by being supplied with electric power from the commercial power source 5 to the commercial power source 5 provided in the stand unit 2 via power feeding units P1 and P2 provided in the stand unit 2.

Then, the temperature of the base section 3 is detected by the temperature detecting section 6.
And sends the detected temperature signal to the control unit 7. The control unit 7 determines whether the sent temperature signal is higher or lower than the set temperature set by the temperature setting unit 8, The result is output to the heater control unit 9, and the heater control unit 9 is configured to control the power supply to the heater unit 4 to control the temperature of the base unit 3 to be constant.

A display unit 10 displays a set temperature by operating a temperature setting unit 8 and is controlled by a control unit 7. The placement detecting section 11 detects whether the iron section 1 is placed on the stand section 2 or whether the iron section 1 is detached from the stand section 2.

The power supply section 12 supplies power to these control means. Switches SW1 and SW2 provided on the stand section 2 are turned on when the iron section 1 is placed on the stand section 2, and the commercial power supply 5 is turned on. Power supply units P1 and P
Power is supplied to the iron unit 1 via the power supply unit 2 and the electrode units P3 and P4, and the power is turned off when the iron unit 1 is detached from the stand unit 2; There is no configuration.

Next, the operation of the power supply section 12 will be described with reference to FIG.
