4. Installation
Installing the soldering tip is straightforward:
- Ensure the soldering iron is powered off and cool.
- Select the appropriate soldering tip (T210 series for T80, T245 series for T80P).
- Gently insert the soldering tip into the heating core of the soldering iron until it is firmly seated.

5. Operation
Main Interface and Indicators
The soldering iron features an OLED display and two control buttons (Key A and Key B).
- Main UI: Displays target temperature, current tip temperature, heating power, and a hand-held sensor sign.
- Hand-held sensor sign: A point appears on the screen when the handheld is detected; otherwise, it disappears.
- Low voltage prompts: If the input voltage is lower than 9V, the screen will indicate "Vol low" and heating will be disabled.
- No soldering tip prompts: If no soldering tip is detected, the screen will display "No tip". Please insert the soldering tip.
- Start heating prompts: Press button A to start heating.
Temperature Adjustment
To adjust the temperature:
- Click Key A or Key B to enter the temperature adjustment UI.
- Release the button, then click or long press to adjust the temperature.
- After adjustment, the device will automatically return to the main UI after 3 seconds.
Manual Shutdown
Long press Key B to enter the standby UI. The temperature will drop to 50°C, and then the machine will shut down.
Power Adjustment
The soldering iron supports 18-100W adjustable power. You can select the voltage and fine-tune the current to achieve power adjustment.

Power Fine-Tuning:
- On the power tuning interface, click A or B to select the unit (voltage/current/wattage).
- Long press B to confirm selection and trim; long press A to deselect.
- Select OK and long press B to save and exit.
Note: The T80 will jump temperature when using the new heating core, and it will be stable after several uses.
Intelligent Induction and Sleep Mode
The soldering iron features intelligent induction for energy saving and extended heating core life.

The system flow includes different states:
- Working state (main UI): The soldering iron is heated, and the temperature is constant at the user's set temperature. If the handle is not used for a period of time (timing 1: sleep time), it will enter the sleep state.
- Sleep state: The soldering iron is heated, and the temperature is constant at the sleep temperature (default 200°C). It will exit the dormant state and return to the main UI when it senses the hand held or presses the button. Otherwise, after a period of time (timing 2: standby time), it will enter the standby state.
- Standby state: The soldering iron is not heated. It will exit the dormant state and return to the main UI when it senses a hand held or presses a button. Otherwise, the temperature of the soldering iron tip will slowly drop, and when it drops to 50°C, it will enter the shutdown countdown state, and then the screen off state.
- Screen off state: The soldering iron is not heating. In this state, the system is running with low energy consumption, and restarts when it senses a hand held or presses a button.
7. Working Voltage
The soldering iron can set heating power for different voltages from a fast charger. However, two situations may occur:
- If you set the working voltage to 20V, but the actual output is only 12V, you need to set the working voltage in the menu to 12V.
- If the machine restarts during heating, indicating insufficient output power from the fast charger, you can enter the menu to fine-tune the power to achieve the maximum output power.
8. Firmware Upgrade
To upgrade the firmware, follow these steps:
- Download Firmware: Scan the QR code below to download the latest firmware (e.g., T80_APP.atk).

QR code to download the latest firmware for the ALIENTEK T80/T80P Smart Soldering Iron. - Connect to PC: Power off the device. Press and hold the B button, then use a USB Type-C cable to connect to your computer. Power on the device. After about 4 seconds, the screen will display "Upgrade...". Release the button.
- Run Upgrade Software: Open the upgrade software on your PC. It should automatically connect to the device. If not, click to re-connect.
- Load Firmware: Select the local firmware file (T80_APP.atk) and click to start the upgrade. Wait for the upgrade to complete.
9. Maintenance
- When using a new tip for the first time, it is necessary to heat the tin to 250°C first to prevent dry burning oxidation.
- When a new tip is used for the first time, there may be a temperature jump problem, which will stabilize after a few hours of use.
- After using the soldering iron, apply proper tin to the tip to prevent oxidation before disconnecting the power supply.
- The tip of the soldering iron works normally at a temperature of about 300 to 380°C. Do not use it for a long time (more than 420°C) to avoid affecting the life of the tip due to dry burning.
- Do not force the tip when welding.
- If the surface of the tip is not oxidized, use a cloth or other tool to carefully wipe the surface layer, then heat it to 200°C and immediately apply tin to the surface to prevent re-oxidation.
- Do not use a wet sponge with bright water; a semi-dry state is best, otherwise the soldering iron tip is easy to oxidize.
- Do not use flux containing chlorine or excessive acid to avoid corrosion of the surface.
10. Troubleshooting (FAQ)
The summary of common problems and their solutions is shown in the table below:
| Problems and phenomena | Solution |
|---|---|
| Restarts when heating occurs | Check if the output power of the adapter is sufficient. |
| Working voltage setting 20V, screen only displays 12V | Check the maximum output voltage of the adapter. |
| Handheld sensing failure | Contact after-sales service. |
11. Warranty & Support
After-sales Service
The T80/T80P host has a one-year free warranty service in the case of non-artificial damage. Please contact the dealer for warranty service. Soldering tips are consumables; if there is no quality problem, once used they will not be returned.
