4. Safety Information

• Always wear appropriate personal protective equipment, including safety glasses, when operating the soldering iron.
• Ensure adequate ventilation in your workspace to avoid inhaling solder fumes.
• Never touch the hot soldering tip. It can reach temperatures up to 450℃ and cause severe burns.
• Place the soldering iron in its stand when not in use to prevent accidental contact or damage.
• Keep the soldering iron away from flammable materials.
• Do not use the soldering iron if the power cord or plug is damaged.
• Unplug the soldering iron when not in use or before performing any maintenance.
• Keep out of reach of children.

5. Setup

1. Insert the Soldering Tip: Carefully insert the desired C210 series soldering tip into the heating element of the soldering iron. Ensure it is fully seated and aligned with the center hole.
2. Connect Power: Connect the Type-C cable to the soldering iron and then to a compatible PD3.1 or QC3.0 power supply (9-20V). The device will power on automatically.

7. Maintenance

• Tip Cleaning: Regularly clean the soldering tip with a damp sponge or brass wool to remove excess solder and oxidation. This ensures efficient heat transfer and extends tip life.
• Storage: When not in use, ensure the soldering iron is cool and stored in a dry, safe place. Use the protective cap for the tip if available.
• General Cleaning: Wipe the body of the soldering iron with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Inspection: Periodically inspect the Type-C cable and connections for any signs of wear or damage.

8. Troubleshooting

The ALIENTEK T90A features a warning interface to indicate common issues:

• "NO Tip" Error: This indicates that the device has failed to detect the soldering iron tip. Ensure the tip is correctly and fully inserted.
• "Vol low" Warning: The input voltage is below 9V, and the heating function is disabled. Connect the soldering iron to a compatible PD3.1 or QC3.0 power supply providing 9-20V.
• "Tip res-Err" Error: This signifies abnormal resistance of the iron tip. Try re-inserting the tip or replacing it with a new one if the issue persists.

9. User Tips

• For optimal performance, use a power supply that can deliver at least 45W (e.g., 15V/3A or 20V/2.25A) to quickly reach desired temperatures.
• Always tin your soldering tip before and after use to prevent oxidation and ensure efficient heat transfer.
• Experiment with different temperature settings for various solder types and components to find the ideal working temperature.
• Utilize the automatic sleep function to conserve energy and prolong tip life during short breaks.
