6.3.2 Set the Temperature of the De-soldering Gun
When only displaying the “de-soldering gun” alone, click the “TEMP” key to change the temperature. The
temperature of the de-soldering gun can be set between 200℃and 480℃, and the setting method can refer to the
“5.2.1 temperature setting”. But it is best to set the appropriate temperature as the different PCB (see the following
table).
6.3.3 Operation of the De-soldering Gun
WARNING:
`High temperature work will shorten the life of the heater and the suction nozzle which will be oxidated
and damaged because of the too high temperature. So use as low temperature as possible when work.
`Always set the temperature to as low as possible for the work being done.
NOTE: the de-soldering gun cannot to suck the solder when the sucking nozzle of the SMD rework tool is in work
and the bump is in startup state.
1. After switch as the de-soldering work state, wait 3 minutes before beginning the de-soldering operations.
2. Melt the solder: Apply the nozzle to melt the solder after the temperature has stabilized.

Nozzle
PCB
Solder
Lead
Move the lead with the
nozzle slowly.
Absorb the solder by moving the lead back
and forth slowly with the nozzle.
a) Never allow the nozzle to touch the board itself.
b) To confirm that all the solder is melted, observe the inside of the hole and the backside of the PCB. If
this is difficult to do, try slowly moving the lead with the nozzle. If the lead can move, the solder is
melted.
c) Never move the lead by force. If it doesn’t move easily, the solder isn’t yet fully melted.
3. Absorb the solder: After confirming that the solder is completely melted, absorb the solder by squeezing the
trigger on the gun. After fully absorbing all the solder, cool the soldering junction in order to prevent it from
becoming re-melt.
4. Problems during de-soldering: If solder remains, it must solder the component again and repeat the
de-soldering process as above.
5. Clean the tip of the nozzle: Keep the solder-plated section of the nozzle shiny by coating it with a small
amount of solder. If the tip of the nozzle is coated with oxide, the nozzle’s heat
conductivity will be lowered. Coating the tip with a small amount of fresh
solder ensures maximum heat conductivity.
6.3.4 Cleaning during the Process of Operation
The absorbed solder by nozzle must be cleaned in time to insure the unit work normally.
6.3.4.1 Observing the Indicator
1. Make sure that the hole of the nozzle is open and without jam before observing the indicator which can
indicate the parts of the de-soldering gun need clean or not.
2. Pull the trigger and look at the indicator.
3. If the indicator is red, clean the nozzle and heating element, empty the filter pipe, and replace the filters. If the
indicator is blue, cleaning is not necessary and operations can be resumed.
Wipe away any oxide or old solder from the nozzle by the
hole in the center of the sponge.

13
CAUTION:
`The results of the indicator will not be accurate if the hole of the nozzle is closed or if the solder in the hole
of the PCB is not melted.
`Clean the nozzle and heating element with the cleaning pin if there is a noticeable drop in suction efficiency.
6.3.4.2 Replacing the Filter Pipe
Replace the filter pipe as shown step ①~③. During operation, the filter pipe is very hot. Wait until the filter pipe
is cool before replacing the filter.
6.4 Operation of the SMD Rework Tool
6.4.1 Enter or Exit from the State of the SMD Rework Tool
1. Turn on the power switch, click“TOOL3” key into the single displaying state of SMD rework tool.
2. If displaying “-” at the SMD rework tool window, which means the SMD rework tool is in the shutting state
and cannot be operated. At the state, if pressing “TOOL3” key about three seconds, the SMD rework tool
window will shows “ON”, which means the SMD rework tool can work normally.
3. Pressing “TOOL3” key again, the SMD rework tool window will shows “OFF” and then “-”, which means the
SMD rework tool has been into the shutting state.
4. If displaying “---” at the SMD rework tool window, which means the SMD rework tool is in the sleeping state.
The SMD rework tool comes to heat up when waking up from the sleeping state, the “
” lights and when the
temperature is stable, the “
” flickers.
6.4.2 Set the Temperature and Airflow of the SMD Rework Tool
Click “TOOL3” key into the single displaying window of the SMD rework tool, and then click “TEMP ▲” or
“TEMPe” key to change the temperature and click “AIR▲” or “AIRe” key to change the airflow (refer to the
temperature and airflow setting).
Normal Abnormal Solution
Blue or slight amount
of red can be seen.
More than half of the
indicator is red.
If the indicator is more than half red, replace
the filter and clean the nozzle and the inside
of the heating element.
①Pull down
②Automatically spring
③Replace the entire filter pipe with the provided
backup filter pipe.

14
6.4.3 Operation
NOTE: the sucking nozzle of the rework handle cannot suck chip when the de-soldering gun is sucking solder
because the bump has been used by the de-soldering gun.
1. Select the appropriate nozzle to install on the handle.
2. Take up the handle and the handle can come into the normal work state (if it is in sleeping state).
3. Turn the knob on the middle of the handle to make the sucking pole out or in. install an appropriate sucking
nozzle on it.
4. When de-soldering the chip, once the solder has melt, click “VACCUM” key, it can start-up the bump and
then use the sucking nozzle to suck the chip. Close the bump by clicking “VACCUM” key again.
5. After finishing work, take down the handle on the holder. When the temperature is less than 100℃, it enters
into the sleeping state.
CAUTION:
For prolong the life of the heater and protect the safety of the chip, use as low temperature as possible and as
big airflow as possible if it can finish the de-soldering work.
6.5 On Line with the Hot Plate
This unit can work together with a kind of the preheat plate by the special connection cord.
Take out the cord from the package. One end of the cord connects with the six-pins socket on the back of the unit,
and the other end connects with preheat plate. Detailed operation can refer to the manual of the preheat plate.
Ⅶ. Temperature Calibration
1. If the unit is locked by password, it will not be able to calibrate the temperature and you must input the right
password.
