having to reset the temperature each time, and
accurate and safe temperature control is assured.

937 station.

If the power is turned off while the card is inserted, when
the power is turned on again, the previously set
temperature will be used to heat up the soldering iron.
For greater convenience and soldering efficiency, two
stations can be securely stacked.
NOTE:
If the power switch is turned off during any step of the
temperature adjustment procedure, the setting will not be
stored in memory.
