Feature:Specification:1. Working voltage: AC 110V~240V 60W.2. Temperature range: 180~500, the error after calibration is less than +/-5.3. Use 900 series soldering iron tip, plug-in heating core.4. Tin time: 18~20s.5. Alarm: EAO heating element is open.Set temperature operation:(1) Press the + button once to increase the temperature, and long press the + button to increase the temperature continuously.(2) Press the button to decrease the temperature, long press the button to decrease the temperature continuously.(3) When there is no button for 3 seconds, the newly set temperature will be memorized, and the temperature will be kept at the next startup.(4) When the heating core reaches the set temperature, the temperature of the soldering iron tip can reach the set value after about 30~50s.Calibration operation: (Generally choose 320 degree calibration.)(1) Put the soldering iron tip on the thermometer after powering on for 90s, and add solder to the soldering iron tip to make the soldering iron tip and the thermocouple fully contact.(2) Wait for 2~4s after the thermometer shows that the temperature stabilizes, and record the temperature of the thermometer.(3) Remove the soldering iron from the thermometer and press + and at the same time to enter the temperature calibration interface.(4) Input adjustment amount:E.g:Set the temperature to 290C, and the actual measured temperature is 282C, then press to display 08C on the LCD.Set the temperature to 290C, and the measured temperature is 300C, then press to display -10C on the LCD.(5) Press the + and - button at the same time to exit the temperature calibration interface.Press # button once to switch C/F.Package included:1*Electric soldering iron1*Anti-static tweezers1*Rosin1*Soldering iron bracket1*Maintenance copper wire1*Tin wire5*Soldering iron tip1*Soldering iron tip silicone protective cover1*Storage bagPackage List:
