ABSTRACT:
A soldering iron temperature regulator capable of calibrating the measuring error of the temperature sensor for detecting the tip temperature of a soldering iron at ordinary temperature. It comprises a temperature control part for adjusting the heating temperature of the heater on the basis of the set value of a temperature setting part and the measured temperature by a temperature sensor, a variable resistor connected to the temperature sensor, and a calibration circuit for matching the tip measured temperature by the temperature sensor with the ambient temperature of the tip at room temperature, in which after matching the measured temperature by the temperature sensor with the ordinary ambient measured temperature by the output adjustment of the calibration circuit, the heating temperature of the tip is set to a specified temperature by the temperature setting parts, and this value is entered into the temperature control part.
