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
