When the handle is inserted into the stand, it will automatically enter sleep mode. The soldering station is equipped with three soldering iron tips (I, IS, K). The temperature of the soldering station is controlled by the chip program, which is different from the traditional soldering station that uses AC voltage to control the temperature, and the heating speed is fast and accurate. & 65279;Preset 4 sets of standby temperature (0,150,180,200), "0" is closed, and it can be used when it is lifted. Software program control, hang up instantly. Powerful function, with 3 groups of preset memory temperature, short press for one second to read,  long press for three seconds to store. Celsius/Fahrenheit (C/F) conversion Temperature compensation function& 65292;the temperature of the soldering iron tip is automatically  compensated during the welding process, so that the soldering iron tip is always kept at the set  temperature. Key lock/open Buzzer on/off The protective cover of the soldering iron stand provides effective safety protection. Short-circuit reminder function, when the soldering iron tip is short-circuited, the machine will automatically remind you. & 65279; Specification& 65306; Power  120W Input voltage  AC220V/AC110V Frequency  50-60Hz Temperature range
