BASIC TROUBLESHOOTING GUIDE
PROBLEM 1: THE UNIT HAS NO POWER
1. Check if the unit is switched ON.
2. Check the fuse. Replace with the same type if fuse is blown.
3. Check the power cord and make sure there are no disconnections.
4. Verify that the unit is properly connected to the power source.
PROBLEM 2: TEMPERATURE IS NOT INCREASING
Description: Tip temperature does not increase, display shows the word “Err0”
SOLUTION:
The solder Iron is not connected or its connection is loosely connected to the main sta-
tion. Plug the solder iron firmly and lock into position.
CASE 2: Solder Iron is properly connected, display still shows “Err0”
SOLUTION:
The sensor or wires of the sensors may have been damaged. Replace heating element
(sensor is integrated into the heating element). Check the wirings of the solder iron pen.
CASE 3: Solder Iron is properly connected, display shows “Err1”
SOLUTION:
The heating element may have been reached the end of it life. Replace heating element.
Check the wirings of the solder iron pen.
PROBLEM 3: SOLDER IRON IS OVERHEATING
Description: Solder iron tip is getting too hot while the displayed actual temperature
stays below 200.
SOLUTION:
If the heating element have just been replaced then the heating element wires might
have been soldered incorrectly. Heating element have polarities and should be soldered
accordingly.
PROBLEM 4: OTHER PROBLEMS NOT MENTIONED IN THIS DOCUMENT
SOLUTION: Please bring the unit to a certified service station.

To calibrate the tip temperature:
1. Set to desired working temperature.
2. Use an external temperature sensor to check the tip temperature.
3. Wait for the display to reach the set temperature of 350C, then al-
low the tip to idle at the sensor for 60 seconds for proper tempera-
ture measurement.
4. Press and hold the set button.Wait for the upper display to change
to “Set 01”.
5. Repeatedly press the set button unit upper display shows “Set 04”.
The lower display would show “ 0000” . This indicates that indicates
