ABSTRACT:
A card controlled temperature control device for a soldering iron in which only a specific person can set and control the tip temperature of the soldering iron. The device comprises a control card having a temperature setting part, a card identification part for identifying that the control card is capable of setting the temperature, a set value judging part for judging if the input numerical value of the temperature setting part is in the allowable range or not, and a temperature control part for controlling the heater of the soldering iron on the basis of the set value within the allowable range. These enable the iron tip temperature to be set and operated by a specific person having specific control card and unauthorized improper operation is prevented.
