Thermostat intelligent LCD display electric soldering iron 60W repair soldering iron tip multimeter Welding gun set  Product Name: Intelligent Digital Display Electric Soldering Iron Heating core: ceramic heating core Length: about 146CM Plug: EU 220V/US 110V Working voltage: AC240~200V 50HZ/AC110V 60HZ Temperature range: 180~520°C, the error after calibration is less than +/-5°C; Use 900 series soldering iron tip, plug-in heating core Tin time: 18~20S Alarm: EA0 heating element open circuit Set temperature operation: 1: Press the + button once to increase the temperature by 5 degrees, long press + the temperature to increase continuously. 2: Press the-key once to decrease the temperature by 5 degrees, long press-the temperature to decrease 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 about 30~50S, the temperature of the soldering iron tip can reach the set value. 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 2~4s after the thermometer shows that the temperature stabilizes, and then 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 For example: set the temperature to 290C, and the measured temperature is 282. Then press the LCD to display 08C, Set the temperature to 290C, and the measured temperature is 300. Then press the LCD display to -10C, 5: Press + and-at the same time to exit the temperature calibration interface. C/F conversion: Press the + and-keys at the same time without powering on, and don’t let go. Turn on the power at this time, release the two buttons when you see the LCD display, then enter the setting menu, C or F is displayed at this time. Press the + key to select C/F, and press the two keys at the same time to exit the setting. In the setting state, stop heating, and start heating after exiting.   Black/White Package 1  Black and white packaging 1 Digital display soldering iron EU / US * 1 Soldering iron tip* 1 Soldering iron rack*1 Thread cutter* 1 0.5M red line * 1 Tin wire* 1 Sponge* 1 casing*1 Ceramic heating element * 1 Tweezers* 1 8 * 25cm polyester fiber storage bag * 1     Black/White Package 2  Black and white packaging 1 Digital display soldering iron EU / US * 1 Soldering iron tip* 1 Soldering iron rack*1 Thread cutter* 1 0.5M red line * 1 0.5M black line*1 Casing*1 Tin wire* 1 Sponge* 1 8-in-1 screwdriver * 1 Ceramic heating element * 1 Tweezers* 1 8 * 25cm flannel storage bag * 1     Black/White Package 3  Black and white packaging 1 Digital display soldering iron EU/US* 1 Soldering iron tip* 1 Soldering iron rack*1 Thread cutter* 1 0.5M red line * 1 0.5M black line*1 Tin wire* 1 Tweezers* 1 Sponge* 1 8-in-1 screwdriver * 1 Casing*1 Ceramic heating element * 1 multimeter*1 8 cm * 25 cm polyester fiber storage bag * 1 Storage bag*14.
