5. Setup
- Unpack: Carefully remove all components from the packaging.
- Placement: Place the main unit on a stable, heat-resistant surface.
- Connect Soldering Iron: Insert the soldering iron's connector into the "SOLDERING" port on the main unit.
- Attach Iron Holder: Secure the soldering iron holder to the main unit using the provided screw, if applicable, or place it securely next to the unit.
- Insert Soldering Tip:
- Ensure the soldering iron is cool.
- Gently insert the desired T12 compatible soldering tip into the soldering iron handle until it is fully seated. Refer to the image below for correct insertion.

- Power Connection: Connect the power cable to the main unit and then to a suitable electrical outlet (110-240V).
6. Operating Instructions
6.1 Power On/Off
- To power on, press the power switch. The display will illuminate.
- To power off, press the power switch again.
6.2 Setting Temperature
- Adjusting Manually: Rotate the adjustment knob (MIN/MAX/MENU) to increase or decrease the desired temperature. The display will show the set temperature.
- Using Preset Channels: Press the adjustment knob to cycle through the 3 preset temperature channels (CH1, CH2, CH3). Each channel can be pre-configured for specific temperatures.

6.4 Sleep Mode and Automatic Shutdown
- The unit will enter sleep mode after a period of inactivity (default or user-set 5/10/30 minutes). The display will indicate "SLP".
- After 30 minutes in sleep mode, the unit will automatically shut down for safety.
- To wake from sleep mode, simply pick up the soldering iron or press any button.
6.5 Temperature Calibration
If the displayed temperature does not match the actual tip temperature (verified with a thermometer), the unit can be calibrated. Refer to the full manual for detailed calibration steps, which typically involve entering a calibration mode and adjusting the offset.

7. Maintenance
- Tip Cleaning: Regularly clean the soldering tip using the included brass wool tip cleaner or a damp sponge. This helps maintain tip performance and longevity.
- Tip Tinning: Always tin the tip with a small amount of solder before storing and after cleaning to prevent oxidation.
- Replacing Tips: Ensure the iron is cool before replacing tips. Follow the tip insertion steps outlined in Section 5.
- Unit Cleaning: Wipe the main unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No power supply; faulty power cable. | Check power connection; try a different outlet; inspect power cable for damage. |
| Soldering iron not heating up. | Iron not properly connected; faulty heating element/tip; incorrect temperature setting. | Ensure iron is fully plugged in; check tip insertion; increase temperature setting. |
| Temperature unstable or inaccurate. | Tip not fully inserted; need for calibration. | Ensure tip is fully seated; perform temperature calibration (refer to Section 6.5). |
| Solder not melting easily. | Temperature too low; oxidized tip. | Increase temperature; clean and re-tin the soldering tip. |
