1. Connect the desoldering iron’s power cord to
an electrical outlet, and the heating element
will begin heating up.
2. Allow the desoldering iron to preheat for appr-
oximately 3 to 5 minutes, then, push down the
piston rod.
3. Cover the component's pin with the desolderi-
ng nozzle, and melt the solder joint complete-
ly. Then, press the desoldering button to extr-
act the solder completely.
4. When the operation is complete, DISCONNECT
the power cord.
NOTE: When using the desoldering nozzle for the
first time, coat the nozzle with a new layer of
solder(we recommend using rosin core solder) to
prevent oxidization.
III. OPERATION
IV. MAINTENANCE & PRECAUTIONS
CAUTION:
A. Melt the solder completely before pressing the de-
soldering button.
B. If there are solder remains inside the PCB’s hole, r-
esolder. Then, repeat the desoldering procedures.
C. If the component’s pin is stuck on the sidewall ins-
ide the hole, and you are unable to extract the sol-
der completely. Add solder to resolder, then, use
the desoldering nozzle to melt the solder joint co-
mpletely. Move the nozzle back-and-forth, and get
the component’s pins moving together with the n-
ozzle. When the component’s pinsare no longer in
contact with the sidewall of the hole, press the de-
soldering button to extract the solder completely.
D. Clean the tin storage tube regularly to prevent in-
effective desoldering caused by the over accumul-
ation of scrap solder.
1. If a layer of oxidization forms on the surface of
the desoldering nozzle, a misconception can be
