9.1.4.2 Disassembly the Soldering Iron Handle
1.
Turn the power switch off and disconnect the power plug. Disconnect the handle connector from the station,
and disassemble it after it cooling down.
2.
Pull out the tip
①
. Turn anticlockwise the ring
②
and take it down.
3.
Pull out the inlay piece
③
towards the tip way.
4.
Take out the heater element
⑥
from the iron handle
⑾
towards the tip way.
5.
Push the handle cord
⑩
forward lightly, until the connection cord PCB
⑨
has been push out.
6.
Don’t use metal tools such as pliers to remove the heater element or the tip enclosure from the handle instead
of using heat resistant pad.
9.1.4.3 Checking the Heating Element
Measure the heating element when it comes back to room temperature:
1.
Resistance value of heating element (cord shield) under 4
Ω
.
2.
Resistance value of sensor (Red and Green wire) under 10
Ω
.
3.
If the resistance value isn’t normal, replace the heating element.
9.1.4.4 Change the Heating Element or the Sensor
1.
Measure the resistance values between pin4 and pin1 or pin4 and pin2, between pin5 and pin1 or pin5 and
pin2, between pin6 and pin1 or pin6 and pin2, between pin6 and pin4 or pin6 and pin5. If they are not
∞
, the
heating element and sensor or vibrator switch are touched. This will damage the PCB.
2.
Measure the resistance value ‘a’, ‘b’ and ‘c’ (refer to the above form) to confirm that the leads are not twisted
and that the grounding wire is properly connected.
3.
Ensure the pins have inserted to the end.
9.1.4.5 Check the Handle Cord of the Soldering Iron
Check the resistance between the pins of the plug and the wires on the terminal. The value should be 0. If it is
greater than 0 or is
∞
, the cord should be replaced.
Pin1: Blue Pin2: Red
Pin3: Green Pin4: Shielded Conductor
Pin5: Lining of the Shielded Conductor (White) Pin6: White
