17. Maintenance
Daily inspection requirement items are as follows:
Note: when the inspection, turn off the power and cool down the iron tip.
1) Existence of solder wire:
If the solder wire is not sufficient, please change to new one.
2) Wear of iron tip
If soldering result become unstable, please change it to new one. The life time of the
iron tip depends on the heating time, the solder feeding point and speed.
3) Breaking of heater
The causes of a breaking of heater when the lamp for indication of temperature
error is on and the temperature controller is normal are as follows:
(1) The breaking of heater. Change the iron cartridge
(2) The breaking of the relay cord. Change the iron cord.
(3) The iron tip is worn. Change the iron cartridge
4) Air pressure
Make sure the air pressure if it is adequate. (0.4-0.6MPa)
5) Clog of the tube set
If the top (exit side) of the tube set clog with a flux or solder wire, please remove and
clean it with alcohol.
6) Up/down movement
Make sure if the up/down movement of iron unit of iron unit is smooth. Also, make
sure if there is no flux sticking in moving parts.
7) Cutting blade and pinch roller for solder wire feeding
Make sure flux or solder does not stick to the above parts. If so, clean it with a soft
(brass) wire brush and alcohol.
After every 5,000 points soldering
Check the solder tip temperature with a thermometer. If there is difference between
measured and actual temperature, do the calibration of TCL1 in the system
parameter.
Every month
Make sure a solder wire run through the solder wire tube. If not, clean the inside
tube or replace.
Every year
Send the thermometer to an authorized agent for the calibration.
