CAUTION
Solder the wires so that the solder in the lead hole
can be seen from both sides of the board. Insert the
heater lead (RED) from the opposite of IC.
F. Cut away the unneeded portion of the lead
wires and then cover the heater terminal with
the heater tube.
G. Securely insert the grounding spring into the
round sleeve on the opposite side from the lead
wire.
H. Replace the board along the groove on the grip,
making sure that the temperature button socket
is facing the right direction.
I. Reassemble by following the disassembly
procedure in reverse, and adjust the CAL to
calibrate the unit.
-When calibrating the soldering iron,use a new tip
as the temperature of a used tip may be lower
than normal due to deterioration.
-Do not set the temperature above 480℃ during
the CAL adjustment, as this may damage the unit.
1. After confirming that the power is off, pull out
the currently inserted button and insert the
desired one.
2. Pull back the handle cover to expose the CAL
adjustment hole.
3. Insert the plug of the power cord into the outlet.
The heater power lamp will begin blinking when
the soldering iton has reached the set temper-
ature.
4. While measuring the tip temperature; with a tip
thermometer, adjust the CAL using straight-
edge(-)screw driver. Turning the CAL clockwise
increase the temperature; turning it counter-
clockwise decrease the temperature.
If you have the P.W.B. with the hole for sensor
lead (blue) is located 2mm away from the edge,
please bend the sensor lead as shown in the figure
below. Then cover the heater tube.

No.A1275(240V)
Always remove the power plug from the
outlet and wait for the soldering iron to
cool completely before replacing parts
or performing maintenance. Leaving the
unit plugged in during these operations
is dangerous and may result in electric
shock, failure, or reduced performance.
Replacing the Heating
Element
A. Remove the temp. button.
B. Remove the nut and disassemble the tip section.
C. Remove the screws and then remove the nipple.
D. Carefully pull out the heating element and
P.W.B., then remove the grounding spring.
E. Place a new heating element on the board as
shown in the figure below and solder it into
place. Check the number printed on the new
heating element. Errors in replacement may
result in failure or accident.
