If solder is not wet on the tip surface, the tip is oxidized.

*Example of an oxidized tip that has blackened due to oxidization
Case 1 If the tip oxidizes.
Case 2 How to prevent tip oxidization.


Case 1. If the tip oxidizes.

Point 1: Use cleaning wire (HAKKO 599B) or fine sandpaper to remove only the surface oxide. Apply new solder to the tip at 250ºC.
Point 2: Remove oxide and recover the tip surface with chemical paste ( HAKKO FS-100 )

How to remove oxide with HAKKO FS-100:

1. Dip the tip into the chemical paste for 2-3 seconds. (Use a temperature setting of around 300ºC.) Procedure 1
2. Remove the chemical paste using HAKKO FT-700, a cleaning sponge or cleaning wire. Procedure 1 Procedure 2 Procedure 3
3. Repeat steps 1 and 2 several times. Make sure that the oxidation film has been removed, and recover the chemical residue using solder. Procedure 3

Point 3: The removal process will be more effective if tip polisher (HAKKO FT-700) is also used.
Point 4: If solder is not wet to tip surface after removing the oxidation, replace the tip with a new one.

Case 2. How to prevent tip oxidization.

Point 5: Always keep the end of the tip coated with solder so as not to expose it to the air.

After finishing work:
  1. Wipe the tip clean with a cleaning sponge.
  2. Apply new solder to the end of the tip
Point 6: Use HAKKO 599B (cleaning wire).
Flux contained in HAKKO 599B cleaning wire will remain on the tip slightly and prevent oxidization.

Cleanse the soldering tip with a wet sponge. Cleanse the soldering tip with dry cleaning wire.

Apply solder to the soldering tip while the power is on.
Apply fresh solder to the end of the tip as shown.
Apply solder to the tip while the power is on.
Point 7: Turn the power off when not using the iron.
Point 8: Use soldering iron at lower set temperature.(Do not raise the temperature unnecessarily.)
