5. Setup
5.1 Power Connection
The ANENG SL107 soldering iron is powered via a Type-C interface. It supports PD/QC fast charging adapters, power banks (9-20V), or DC power supplies (9-24V).
- Connect the provided Type-C charging cable to the soldering iron's power supply interface.
- Connect the other end of the cable to a compatible power source (e.g., PD/QC fast charger, power bank, or DC power supply).
- Ensure the power source provides adequate voltage (9-24V) for optimal performance. Note that 5V input will limit the maximum temperature.

5.2 Initial Power On
Once connected to power, the device will warm up. Press the power key to enter the operation interface.
6. Operating Instructions
6.1 Basic Soldering Steps
Follow these general steps for effective soldering:

- Warm Up: Connect the power supply and press the power key to enter the operation interface. Allow the iron to reach the set temperature.
- Dip in Rosin: After preheating, dip the soldering iron tip in rosin for easy welding.
- Upper Tin: Add an appropriate amount of tin wire to the tip and melt it well.
- Welding: Melt the tin wire and wrap it around the solder joint.
- Clean Up: Impurities can be soaked in and cleaned up on your sponge.
- Cooling: Place the electric soldering iron in a safe holder and allow solder joints to cool naturally.
6.2 Temperature Adjustment and Heating Performance
The ANENG SL107 allows for adjustable temperature settings. The heating time to 300°C varies based on the input voltage and power:

| Voltage | Current | Power | Heating Time to 300°C |
|---|---|---|---|
| 20V | 3.25A | 65W | 9S |
| 15V | 2.5A | 37.5W | 13S |
| 12V | 2A | 24W | 20S |
| 9V | 1.5A | 13.5W | 30S |
| 5V | N/A | N/A | Can only reach about 200 degrees, not 420 degrees. |
6.3 Menu Navigation and Settings
The ANENG SL107 features 12 function menus for customization. Press and hold two buttons simultaneously to enter the A La Carte mode.

Menu options include:
- Standby temperature
- Temperature step
- Voltage information
- Version information
- Temperature calibration
- Power on heating
- Spin show (display rotation)
- Language choose
- Temperature unit (℃/℉)
- Work voltage
- Sleep time
- Standby time
Use the power key/down value button (6 in Product Overview) to navigate and adjust settings.
7. Maintenance
7.1 Cleaning the Soldering Tip
Regular cleaning of the soldering tip is crucial for optimal performance and longevity. Use a damp sponge or brass wool to wipe off excess solder and impurities from the tip. Ensure the sponge is only damp, not soaking wet, to avoid thermal shock to the tip.
7.2 Storage
When not in use, allow the soldering iron to cool completely before storing. Store it in a dry, safe place away from moisture and direct sunlight. Do not wet the machine or use it in a humid environment.
8. Troubleshooting
- Soldering iron not heating: Ensure the Type-C cable is securely connected to both the iron and a compatible power source. Verify the power source is active and providing sufficient voltage (9-24V).
- Temperature not reaching desired level: Check the input voltage. If using a 5V power source, the maximum temperature will be limited to approximately 200°C. Use a higher voltage power source (e.g., 20V for 420°C).
- Display issues: If the VA reverse display is not functioning correctly, try restarting the device by disconnecting and reconnecting the power.
- Poor solder joints: Ensure the soldering tip is clean and properly tinned. Adjust the temperature as needed for the specific solder and components being used.
