- Ensure the soldering iron is cool or use a heat-resistant tool to handle the tip.
- Gently pull the existing tip out of the soldering iron handle.
- Insert the new T12 tip firmly into the handle until it clicks into place.

5. Maintenance
5.1 Soldering Tip Cleaning
Regularly clean the soldering tip to ensure optimal performance and longevity. Use the brass wire ball (5) to remove excess solder and oxidation. For more thorough cleaning, dampen the cleaning sponge (4) with water and wipe the tip. Avoid excessive pressure.

5.2 Station Cleaning
Ensure the unit is powered off and unplugged before cleaning. Wipe the exterior of the soldering station and stand with a soft, dry cloth. Do not use abrasive cleaners or solvents.
5.3 Storage
When not in use, store the soldering station and its components in a dry, dust-free environment. Ensure the soldering iron tip is clean and tinned before storage to prevent oxidation.
6. Troubleshooting
- Station does not power on: Check the power cable connection and ensure the power outlet is functional. Verify the power switch is in the 'ON' position.
- Soldering iron not heating: Ensure the soldering iron cable is securely connected to the station. Check if the tip is properly inserted. Verify the temperature setting is above ambient.
- Temperature unstable: Ensure the tip is clean and properly seated. Avoid drafts in the work area.
- Tip not melting solder effectively: Clean the tip thoroughly. Ensure the tip is tinned (coated with a thin layer of solder). Increase the temperature if necessary.
