Control card
Each Hakko 941 comes with a small card, which
inserts in the control slot in the front of the unit.
This card is used when entering data for the
process control functions. Any Hakko 941 card
can be used with any Hakko 941 soldering
station.
Using the control card
The control card is used when a value is to be
changed or data are to be entered. The Hakko
941 will operate normally with the card inserted.
If power is turned on with the card inserted, the
station will heat to the temperature set before
the card was inserted.
