A new soldering tip does not fit in the heating element!
The insertion pipe inside the soldering tip is burned onto the heating element. It has been caused by flux seeping into the inside of the soldering tip. Normally the insertion pipe does not easily come away from the soldering tip.

Can I make the HAKKO 936 (white station) ESD protective just by grounding it?
Hakko defines the items whose enclosures are antistatic surface-treated as ESD protective products. Therefore, the HAKKO 936 is not regarded as an ESD protective product just by being grounded.
What are ESD-SAFE products?


What measures can I take when the tip to ground resistance exceeds 2Ω?
The measures to take to lower the resistance for the HAKKO 907/908 are different from those for the HAKKO 900S. Please perform the following procedure to do maintenance.


For HAKKO 907/908
There is a problem with the soldering tip or connecting cord. First lightly sand the parts indicated in the illustration below with abrasive paper to remove dirt, and then measure the resistance again.
