6.2 Soldering Procedure

1. Ensure your work area is clean and well-ventilated.
2. Clean the soldering tip by wiping it on a damp sponge or brass wool.
3. Apply a small amount of solder to the tip (tinning) to improve heat transfer and prevent oxidation.
4. Place the hot tip against both the component lead and the PCB pad you wish to solder, ensuring good contact with both surfaces.
5. Feed solder onto the joint, not directly onto the iron tip. Allow the solder to flow evenly around the joint.
6. Remove the solder wire, then remove the soldering iron. Allow the joint to cool naturally without disturbance.

6.3 Powering Off

To turn off the soldering iron, press and hold the power button until the LED indicator turns off. Allow the tip to cool completely before storing.

7. Maintenance

7.1 Tip Cleaning and Care

• Regularly clean the soldering tip during use with a damp sponge or brass wool to remove excess solder and oxidation.
• After use, tin the tip with a small amount of fresh solder before turning off the iron. This helps protect the tip from oxidation and prolongs its life.
• If the tip becomes heavily oxidized and solder no longer adheres, it may need to be re-tinned or replaced.

7.2 Battery Care

• Avoid fully discharging the battery frequently. Recharge when the battery indicator shows low power.
• Store the soldering iron in a cool, dry place when not in use.
• If storing for extended periods, charge the battery to approximately 50% capacity.
