To test if the heating element of the soldering iron is in working
condition:
Let whole assembly cool down to room temperature and unplug from
electricalsourcesbeforecontinuingthetestsbelow:
1. Followdisassemblingthehandpieceguide.
2. DothefollowingtestsonthehandpiecePCBboard:
Resistancevalueofheatingelement(RED)1923Ω
Resistancevalueofsensor(blue)1.2—3Ω
Note:resistancevalueofsensormayvaryaccordingtoambient
temperature
Aftertestingcheckresultswiththefollowing:
●If the resistance value is not as stated above replace the heating
element.
●Ifa0Ωorinfiniteresistancesaremeasuredcheckforshortsoropen

1. Followthestepsin“disassemblingthesolderingiron”.
2. Unsoldertheheatingelementwires(RED)andthesensorwires(blue).
3. The old heating element can now be detached from the hand piece
