5. Setup Instructions
- Place the soldering station in a stable position on a flat surface.
- Connect the power cable to the power socket on the rear of the unit.
- Connect the soldering iron handle wire to the corresponding port on the front of the unit.
- Turn on the power switch located at the back of the unit. The station will quickly heat up to the last set temperature.
6. Operating Instructions
Menu Navigation:
Press the "*" key to enter the menu mode. Use the "↑" and "↓" keys to switch between menu items and adjust parameters. Press "*" again to confirm and save changes.
- Soldering Iron Temperature Setting (-1-): Adjust the desired soldering temperature. The setting range is 100°C ~ 480°C (212°F ~ 896°F).
- Soldering Iron Temperature Compensation (-2-): Compensate for temperature differences. Setting range: -50°C ~ 50°C (-90°F ~ 90°F). Factory default is 0°C.
- Soldering Iron Sleep Setting (-3-): Set the delay time before the soldering iron enters sleep mode. Options include OFF, 10 minutes to 60 minutes.
- Fahrenheit/Celsius Toggle (-4-): Switch the temperature display between Fahrenheit (°F) and Celsius (°C).
- Password Setting (-5-): Set or change a 3-digit password (000-999) to prevent unauthorized changes to settings. To set for the first time, enter the new password twice. To change, enter the old password once, then the new password twice. To clear, turn off the unit, press and hold "*", "↑", and "↓" keys simultaneously, then turn on the power switch and release after "000" is displayed.
- Exit (-0-): Save current settings and exit the menu.
Shortcut Temperature Buttons:
The unit features three shortcut buttons (CH1, CH2, CH3) for quick temperature adjustments. Press a shortcut button to instantly set the temperature to its preset value. Default presets are: CH1=350°C (662°F), CH2=400°C (725°F), CH3=450°C (842°F).
To modify a preset temperature, press and hold the desired CH button for more than one second. If password protection is active, you will need to enter the password first. Use the "↑" and "↓" keys to adjust the value, then press "*" to save and exit.
Automatic Sleep Function:
When the sleep function is enabled, the soldering iron will automatically enter sleep mode after the set idle time (10-60 minutes) if it is placed on the stand without vibration or button operation. The screen will display "--" and the sleep mark will light up. To wake the unit, press any key. If the sleep lasts for more than one hour, the system will enter standby mode and turn off the heater. The standby icon will light up.
7. Maintenance
7.1. New Soldering Tip Tinning:
Proper tinning of new soldering tips is crucial for prolonging their service life. Follow these steps:
- Before first use, adjust the iron temperature to 200°C.
- Fully coat the tin part of the iron with a layer of solder.
- Clean the tip on the cleaning sponge.
- Adjust the temperature to 300°C and repeat steps 2 and 3.
- Finally, set the temperature to your appropriate use temperature.
7.2. Daily Use and Maintenance:
- Before each use, wipe the soldering tip clean on a cleaning sponge and then perform tin soldering.
- Avoid leaving the soldering tip at too high a temperature for extended periods, as this can crack the electric coating.
- Do not apply excessive pressure or friction to the soldering tip during soldering, as this can damage the tip.
- Before shutting down, wipe the soldering tip clean and apply a fresh layer of tin.
7.3. Soldering Tip Surface Oxide Cleaning:
If the tin layer of the soldering tip has black oxide or dirt and cannot be tinned, it should be cleaned immediately:
- Adjust the iron temperature to 200°C.
- Clean the soldering tip with a cleaning sponge repeatedly until the oxide is removed.
- For serious oxide, use 600-800 mesh emery cloth and alcohol carefully as needed to remove dirt or oxide.
7.4. Replacing the Soldering Tip:
Always use Bakon 500 series soldering tips for replacement. Turn off the soldering power before replacement. After the tip cools to room temperature, remove the old tip, clean any foreign matter from the sleeve, and then replace with a new tip, following the new soldering tip tinning steps.

8. Troubleshooting
Refer to the table below for common issues and their solutions:
| Fault Code | Description | Solution |
|---|---|---|
| S-E | Sensor is open, soldering handle not connected, or handle is abnormal. | Connect the soldering handle or replace another soldering handle. |
| H-E | Abnormal temperature rise, continuous full power heating without heating. | Avoid soldering large solder joints for a long time. Power on again to return to normal. |
| t-E | Internal temperature is too high, heating output stopped in thermal protection state. | Wait for the temperature control to cool to normal, or reduce environmental temperature. Do not block heat dissipation air outlet. |
| P-E | Abnormal voltage detected. | Check mains voltage (should be 100-240V). If the fault persists, contact Bakon service. |
| C-E | Heating coil open. | Re-power on after replacing the soldering handle. If the fault is not resolved, contact Bakon after-sales service. |
