Hello All,
The desoldering gun of my Hakko 700 station is
not heating. The element is OK.
Hakko do not supply schematic information.
I need information on the following parts
to trace the circuit.

AC05D 4YL flat pack made by NEC SCR maybe?
I can't find any data on this part, ratings, lead info etc.

C170IC (an 8 pin integrated circuit)
No luck in finding information on this part also.

All clues greatly appreciated.
Regards,
John Crighton
