The present invention provides quick temperature compensation method for an electric soldering iron and a quick temperature compensable electric soldering iron which includes a static temperature control circuit and a dynamic temperature control circuit, wherein the amount of the static temperature control is mainly depending on the temperature setting signal, real-time temperature detecting signal and the temperature additional signal, while the dynamic temperature control is made on the basis of Kalman digital filter principle. During the dynamic temperature control, the temperature regulation and control signal that has amplified through difference is identified by the function of the heat conduction transmission of the soldering iron head, and the temperature additional compensation is exported, when the temperature regulation and control signal accords with the function of the heat conduction transmission of the soldering iron head. The present invention is implemented to quickly detect and response the change of the thermal load of the iron head without the affect of the interfering noise outside, and to ensure that the iron head is operated at the setting temperature by the quick and effective control on the electrical heating element. Therefore, the rosin joint and cold joint result from the temperature change of the solder during the welding can be avoided, and the welding speed and quality can be improves. Simultaneously, the electric energy is saved and the operating life of the iron head is extended.
