How to Use AIFEN A902PRO
Place the soldering station on a stable and ventilated work surface. Connect the soldering handles and install the required heating cores before powering on the station. After startup, the display shows “—” while the station enters standby mode.
Use the ▲ and ▼ buttons to adjust soldering temperature. Press once for 1°C adjustment or hold the button for rapid temperature changes. The station supports CH1 and CH2 memory presets for storing frequently used soldering temperatures during repair procedures.
The A902PRO also supports independent A/B area operation, Celsius and Fahrenheit switching, key lock mode, buzzer configuration, and standby temperature control for professional repair environments.
Standby Temperature Settings
The AIFEN A902PRO supports configurable standby temperature settings to reduce soldering tip oxidation and improve heating core lifespan.
Available standby temperatures:
- 0°C
- 150°C
- 180°C
- 200°C
- 250°C
- 280°C
Setting standby temperature to 0°C disables standby mode completely. Standby configuration is available through the CH2 setup procedure.
Temperature Calibration
Temperature calibration is recommended after replacing heating cores to maintain accurate soldering performance.
To calibrate the station:
- Turn on the soldering station.
- Hold the SET button in the A/B area.
- Enter temperature calibration mode.
- Adjust temperature using ▲ and ▼ controls.
- Press SET again to save and exit calibration mode.
Accurate calibration improves soldering precision during lead-free soldering and sensitive motherboard repair work.
Key Lock and Buzzer Settings
The A902PRO supports additional system configuration functions.
Key Lock Mode
Press and hold CH1 in area B during startup to enable or disable key lock mode.
Buzzer Settings
Press and hold CH1 in area A during startup to enable or disable system sound notifications.
These functions help improve workflow control in professional repair environments.
Maintenance Recommendations
Regular maintenance helps improve soldering quality and extends soldering tip lifespan.
Recommended maintenance procedures:
- clean soldering tips regularly
- use cleaning sponge or copper cleaner
- avoid excessive soldering temperatures
- apply fresh solder coating after use
- replace worn heating cores when necessary
The A902PRO uses integrated heating cores that can be replaced directly after cooling and disconnecting power.
Do not leave soldering tips at high temperatures for long periods because excessive heat may increase oxidation and reduce thermal efficiency.
Troubleshooting Guide

Check the soldering handle connection and confirm the heating core is correctly installed.
Temperature Instability
Temperature instability may appear after replacing the heating core or using damaged soldering tips. Recalibration may be required.
Poor Heat Transfer
Oxidized or contaminated soldering tips may reduce solder flow and thermal conductivity.
Memory Presets Not Saving
Verify that CH1 or CH2 settings are stored correctly after temperature adjustment.
Excessive Tip Oxidation
Very high soldering temperatures may damage soldering tip coating and reduce heating efficiency.
Standby Mode Problems
Check standby configuration settings and verify correct heating core compatibility.
