2.Overview
This desoldering tool uses high-frequency eddy current heating, which
makes the nozzle heat up quickly to melt the solder in the pad of the PC
B through-hole devices. The vacuum pump is started by the switch of
the desoldering gun switch to generate vacuum to suck the liquid tin
into the tin storage tube to achieve the purpose of quickly disassemblin
g the through-hole components. At the same time, it can also be used
for tin removal on the surface of the pad to improve maintenance
efficiency.
3.Product Characteristics
LCD display, touch button for comfortable operation.
Novel appearance design.
Powerful built-in vacuum pump.
Precise digital temperature calibration.
Function of counting tin absorbing times.
Support the function of preventing blockage.

according to the above steps.
* It is recommended to use a 191/192 thermometer to measure the tip
temperature.

14
* If the password is locked, the temperature cannot be calibrated, and the
correct password must be input to operate.
9.Operation
Melting solder After the set temperature is stable, use the nozzle of the
desoldering tool to melt the solder.
Solder removal After confirming that all the soldering tin has been
melted, press the red switch (trigger) on the handle to suck the soldering
tin.
Note：1）To check if the solder is completely melted, observe the inside of
the aperture and the back of PCB, if it is difficult, use the nozzle to shake
the pin slightly. If it can be moved, it means that the solder has been
melted.
2）Do not shake the pins vigorously. If the pin does not move easily, it
indicates the solder has not been completely melted
3）Do not leave any solder residue in the PCB aperture.
10.Cleaning and Maintenance
10.1.Maintenance of the Desoldering Nozzle
After using the desoldering tool, please make maintenance to ensure
durability. Solder removal efficiency depends on temperature, quality
and quantity of solder and flux. Please follow the following procedures
for maintenance according to the usage of the desoldering tool:
1）Apply a little solder to the plating part of the nozzle to keep the
nozzle shiny.
2）If the nozzle is covered with oxide, the thermal conductivity will be
weakened. Apply a little new solder on the nozzle to exert the thermal
conductivity function.

15
3) Remove the solder inside the nozzle and the heating element, then clea
n the nozzle with the cleaner, and plate a layer of solder on the nozzle to
protect the coating.
Note: After the desoldering gun is used, the temperature is too high.
During maintenance, please wait it to cool down or wear heat insulation
gloves for safe operation.
10.2.Checking and Cleaning of the Desoldering Nozzle
1) Insert the plug into the power socket, and turn on the power switch to
heat the nozzle.
2）Clean the nozzle hole with a nozzle needle.
3)If there is slight wear and tear, please re-solder the nozzle with new sol
der to avoid oxidation.
4) If the nozzle hole is worn or corroded inside and outside, please
replace the nozzle.
Note：a. Since it is difficult to observe the erosion of the nozzle with
naked eyes, if the tin suction efficiency is reduced while the
performance of other parts is good, it may be that the nozzle is
eroded and should be replaced with a new one.
b.Please select the appropriate size of the needle according to the
diameter of the nozzle. If the solder in the nozzle is not completel
y melted, the needle cannot penetrate the nozzle, please check
the solder coating on the nozzle surface.
Needle completely through the nozzle.

16
c. A layer of special alloy is plated inside and outside the nozzle aperture.
If the alloy layer is eroded due to high temperature, the nozzle will not be
able to maintain a proper temperature.
10.3.Steps of Installing the External Filter
1) Press "Off" on the power switch.
2)When the filter pipe is cooled, pull the trachea support column to the ri
ght and take out the filter pipe.
3)Check the spring filter pipe and tin slag ceramic filter cotton.
Note: The spring filter pipe needs to be replaced when two thirds of the s
older is collected and stored.
The tin slag ceramic filter cotton needs to be replaced when it is hardened
due to the accumulation of solder and flux

17
10.4.Steps of Installing the External Filter
Put the spring filter pipe into the filter pipe, and then put the matching
ceramic filter cotton into the filter pipe. Press the trachea support
telescopic button to fix the filter pipe.
Note: If a large filter cotton is loaded into the filter pipe, it may damage
the desoldering gun or reduce the suction efficiency.
11.Replacing the Heater
11.1.Steps of Removing the Heater
1）Unscrew ①Tip Enclosure and ②Nut
2）Pull out ③Nozzle
3）Unscrew three ④Screws with a screwdriver
4）Pull out ⑤Heater
Note: All operating steps are performed with the power disconnected and
the handle cooled.
11.2.Steps of Replacing the Heater
1）Insert ⑤Heater into ⑥Handle body
2）Screw on three ④Screws
3）Insert ③Nozzle
