* If the unit is locked by password, it will not be able to calibrate the nozzle temperature and you must
input the right password.
7. Operate
Melt the solder
Apply the nozzle to melt the solder after the temperature stabilizing.
CAUTION
1. Never allow the nozzle to touch the board itself.
2. To confirm that all the solder is melted, observe the inside of the hole and the back-side of the P.W.B.
If this is difficult to do, try slowly moving the lead with the nozzle-if the lead moves, the solder is
melted.
3. Never move the lead by force, If it doesn’t move easily, the solder isn’t yet fully melted.
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
resoldered

CAUTION: Never leave any solder remaining inside the hole in the P.W.B.
Problems during desoldering
If solder remains, resolder the component and repeat the desoldering process.
Clean the tip of the nozzle
Keep the solder-plated section of the nozzle a shiny white 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.
Ⅳ、Cleaning During the Process of Operation
The absorbed solder by nozzle must be cleaned in time to insure the unit work normally.
1. Observing the Indicator
While looking at the indicator and with the hole of the nozzle open, pull the trigger and look at the
indicator .If it 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.
CAUTION: The indicator will not operate accurately if the hole of the nozzle is closed or if the
solder in the hole of the P.W.B. is not melted.
If there is a noticeable drop in suction efficiency, clean the nozzle and heating
element with the cleaning pin.
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..
Wipe away any oxide or old solder
from the nozzle using the hole in
the center of the sponge.
