Nozzle Maintenance
1. Inspect and clean the nozzle
●
Turn the power switch ON and let the nozzle
heat up.
●
Clean out the hole of the nozzle with the
nozzle cleaning pin.
●
If the cleaning pin does not pass through the
hole in the nozzle, clean with the cleaning
drill.
●
Check the condition of the solder plating on
the nozzle tip.
●
Check visually if the nozzle was eroded.
CAUTION
The desoldering tool may be extremely hot. During maintenance, please work carefully.
The cleaning pin will not pass through the
nozzle until the solder inside the nozzle is
completely melted.
CAUTION
CAUTION
If the cleaning drill is forced into the nozzle, the drill bit
could break or be damaged.
Please use the proper size cleaning pin or cleaning drill
for the nozzle diameter.
CAUTION
Desoldering efficiency goes down and all other parts appear to be OK, the nozzle is
probably eroded and should be replaced.
The inside hole and the surface of the nozzle is plated with a special alloy. Should
this alloy become eroded by high temperature solder, the nozzle will not be able to
maintain the proper temperature.
Hole is damaged by erosion.
●
If the nozzle is still in a good condition, put some fresh solder on the nozzle tip to
protect solder plated area from oxidation.
• If the cleaning pin and cleaning drill do not pass through the hole
in the nozzle, replace the nozzle.
• If the solder plating on the nozzle tip is worn, replace the nozzle.
• If the inside hole of the nozzle is eroded, replace the nozzle.
