Can I disable the temperature control lockout card on my Hakko 939 Soldering Station? If not can I purchase a replacement card somewhere? Mine has been lost. Thanks!

929/939

Replacement lockout key cards are no longer available for the 939, 929 and 927.

NOTE: The following information is provided as-is and is not supported by Hakko. Modification of any Hakko product will void the warranty.

To disable the temperature lockout feature on the 939, 929 and 927 station:

  • Remove L6 from the sensor board inside the unit and place a solder bridge between the pads. This will cause the temperature controller to permanently read as through a key card has been inserted and allow the temperature to be changed.
