2. 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.
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.
3. Melt the solder.
• Apply the nozzle to the soldered part and
melt the solder.
Note: Never allow the nozzle to touch the
board itself.
• Confirm that the solder is melted.
Note: 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.
Never move the lead by force.
If the lead does not move easily, the
solder has not fully melted.
4. Extract the solder.
After confirming that the solder is
completely melted, extract the solder by
pushing the button on the top of the 807
iron, pressing the trigger switch on the 817
gun, or stepping on the foot switch
(option).
Note: Never leave any solder remaining
inside the hole in the P.W.B.
5. Problems during desoldering.
If solder remains, resolder the component
and repeat the desoldering process.
Wipe away any oxide or old solder
from the nozzle using the hole in
the center of the sponge.
Absorb the solder by slowly
moving the lead back and
forth with the tip of the
nozzle while holding the
button or trigger.
Slowly move the
lead with the nozzle.
