5. Setup and Assembly
5.1 Inserting the Soldering Tip
- Ensure the soldering iron is powered off and cool.
- Carefully align the base of the soldering tip with the opening on the iron's handle.
- Gently push the tip into the handle until it is securely seated. Do not force it.
- To remove, pull the tip straight out. Ensure the tip is cool before handling.
5.2 Connecting Power
- Connect a compatible Type-C power adapter (supporting PD3.1/QC3.0 protocols) to the Type-C port on the soldering iron.
- Ensure the power adapter provides a voltage between 9V and 28V for optimal performance.
6. Operating Instructions
6.1 Powering On and Initial Setup
Once connected to a power source, the soldering iron will power on automatically. The IPS LCD display will show the current status.
6.2 Understanding the Display Interface
The display provides real-time information:
- Set Temperature: The desired temperature for the soldering tip.
- Three-speed Quick Temperature: Indicates the selected quick-access temperature preset (1, 2, or 3).
- Real-time Temperature: The current temperature of the soldering tip.
- Heating Power Bar: Visual indicator of the current heating power.
- Handheld Induction Sign: Indicates if the iron is being held or is in sleep mode.
- Operating Voltage: The current input voltage from the power supply.
- Heating Current: The current drawn by the heating element.
- Heating Power: The current power consumption in Watts.
6.3 Adjusting Temperature
The T90 offers quick temperature adjustment. Use the controls to cycle through preset temperatures or fine-tune to your desired value between 80°C and 450°C. The three-speed quick temperature adjustment allows for rapid switching between common soldering temperatures (e.g., 200°C, 350°C, 450°C) without wasting time.
6.4 PD Power Supply and Performance
The T90 supports PD fast charging heads, power banks, and DC power adapters. The performance varies based on the input voltage and current:
| Operating Voltage | Operating Current | Power | Melting Time |
|---|---|---|---|
| 28V | 5A | 140W | 3S |
| 20V | 5A | 100W | 5S |
| 20V | 3.25A | 65W | 8S |
| 12V | 3A | 36W | 13S |
| 12V | 2A | 24W | 20S |
| 9V | 2A | 18W | 30S |
Note: If the input voltage is below 9V, the temperature rise will be slow, and the heating function may be disabled.
6.5 Inductive Sleep Function
The T90 features an inductive sleep mode to extend the service life of the heating core and save power. When the main unit is placed down, it automatically enters sleep mode. When picked up, it instantly wakes up and resumes operation.
7. Maintenance
- Tip Cleaning: Regularly clean the soldering tip using a damp sponge or brass wool to remove oxidation and old solder. This ensures efficient heat transfer and prolongs tip life.
- Tinning the Tip: Always tin the tip with a fresh layer of solder before storing to prevent oxidation.
- General Cleaning: Keep the body of the soldering iron clean and free of dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the soldering iron in a dry, safe place when not in use, preferably in its original packaging or a protective case.
8. Troubleshooting
The T90 Smart Soldering Iron features a warning interface to help diagnose common issues:
-
⚠️ NO Tip: Device failed to detect soldering iron tip.
Solution: Ensure the soldering tip is correctly and securely inserted. Power cycle the device if necessary.
-
⚠️ Vol low: Input voltage below 9V, heating function disabled.
Solution: Check your Type-C power adapter. Ensure it provides at least 9V and is functioning correctly. Replace with a compatible PD3.1/QC3.0 adapter if needed.
-
⚠️ Tip res-Err: Abnormal resistance of iron tips.
Solution: This indicates a problem with the soldering tip itself. Try re-inserting the tip. If the error persists, the tip may be faulty and require replacement.
General Troubleshooting:
- Iron not heating: Check power connection, ensure the power adapter is working, and verify there are no warning messages on the display.
- Poor solder joints: Ensure the tip is clean and tinned. Adjust temperature as needed for the specific solder and components.
9. User Tips
- For best performance and fastest heating, use a power adapter capable of delivering 28V/5A (140W).
- Experiment with the three quick-access temperature settings to find the most suitable temperatures for your common soldering tasks.
- Take advantage of the inductive sleep feature by placing the iron in its stand when not actively soldering to save power and prolong tip life.
- Always ensure your work surface is protected and stable to prevent accidental burns or damage.
