When soldering, flux from the solder is condensed on the metal ring on the handpiece. These residues are insulating and create false contacts when the handpiece is on the stand, therefore the sleep and hibernation features may malfunction.
We recommend the periodic cleaning with a solvent the metal ring and handpiece support.
The handpiece has a life period and it is normal that due to wear it might be necessary to replace it.

JBC cartridge

The cartridge is made of the heating element which has the heating system, a temperature sensor and a long life tip.

The long-life tip is basically made of:
1. Copper
2. Iron
3. Chromium
4. Tin plate

Tip care recommendations

Except for the copper core, the rest of metals are placed galvanically on relatively thin layers, therefore it is necessary to avoid anything which could cause their destruction.
To clean the tips, use the sponge included with the stand and check that it is slightly misted.
Only deionized water (car battery water) should be used in order to wet the sponge. If normal water was to be used, it is very likely that the tip will become dirty due to the salts dissolved within the water.
To re-tin the soldering tips, we recommend using the TT 9900 tip tinner/cleaner ref. 9900000.
