9. MAINTENANCE
Changing the solder pot
CAUTION
After changing the solder pot, measure the
temperature again. If the measured value is different
from the displayed temperature, enter an offset.
WARNING
When the power is ON, the temperature of the
melted solder in the solder pot is approximately
450℃/842℉. Before changing the solder pot, be
sure to unplug the power cord and let the solder
and the unit cool to room temperature.
Replacing the heating element
1. Using the hexagon wrench (provided with the

Otherwise, the temperature may not increase
properly.
1. Loosen the screws on both sides of the unit.
(Fig. 1)
NOTE:
Removal is unnecessary.
2. Pull out the solder pot. (Fig. 2)
3. Remove the setscrews (6 pieces) on the unit.
(Fig. 3)
4. Slide the front panel frontward, disconnect the two
connectors (Fig. 4) from the connector circuit
board, and then pull out the units of the heating
elements (Fig. 5).
5. Insert the right and left heating elements in the
reverse procedure to removing the heating elements.
After finishing the maintenance, measure the
temperature of solder. If the measured value is
different from the display temperature, enter an offset.
CAUTION
The heating element is a discrete type.
The right heating element is equipped with a sensor.

8. IN CASE THE DISPLAY AND THE ACTUAL TEMPERATURE IS DEFFERENT
●
Entering offset value
The offset value was set to 0℃ at factory.
Example:
When the set temperature is 400℃ and the actual
solder temperature in the solder pot is 350℃; The
difference between the two is +50℃. Therefore,
enter 050 instead of the current offset value.
1. Press the button on the front panel.
• This will set the station to offset value entry mode.
2. Enter the offset value
The allowable ranges for offset values are from
–70 to +70℃ (In ℉ mode from –158 to +158℉).
a. Entering the hundreds digit
• Press the or button to set the desired
figure. In ℃ mode, 0 (plus) or - (minus) can be
selected. (In ℉ mode, 0, 1 (plus) or -, -1 (minus)
can be selected.)
When the desired figure is displayed, press the
button to enter. The tens digit will begin to flash.
b. Entering the tens digit
• Press the or button to set the desired
figure. Any value from 0 to 7 (In ℉ mode, 0 to 9)
can be selected. When the desired figure is
displayed, press the button to enter.
The units digit will begin to flash.
c. Entering the units digit
• Press the or button to set the desired figure.
Any value from 0 to 9 (In ℉ mode, same value can
be selected.) When the desired figure is displayed,
press the button to enter.
Once you can check the display and the measured
temperature, all the settings are finished.
When the temperature of solder reaches the set
value, the buzzer sounds. About 5 to 10 minutes later,
measure the temperature of solder. If the measured
value is different from the displayed temperature,
match them with each other by entering an offset.
