ABSTRACT:
A card controlled temperature control device for soldering iron in which only a specific person can set and control the tip temperature of the soldering iron. The device comprises a card having a specific identification code, a card identifier for identifying the idententification code, an input section for entering a set value, a set value judging component for judging if the entered set value is in the allowable range or not, and temperature control circuitry controlling the heater of soldering iron on the basis of the set value within the allowable range, whereby the iron tip temperature is allowed to be set and operated by a specific person having a specific card and its misoperation is prevented.
