Hakko Electronics FM-202 - Maintenance Procedures

9. MAINTENANCE
• Tip maintenance
1. Tip temperature
2. Cleaning
3. Atter use
4. When the unit is not being used
and the auto power shutoff is not
active.
5. inspecting and cieaning the tip
High temperatures shorten tip life and may
cause thermal shock to components. AIways
use the lowest possible temperature when sol¬
dering. The excellent thermal recovery charac-
teristics of the FM-202 ensure effective solder¬
ing at low temperatures.
AIways clean the soldering tip before use, to
remove any residual solder or flux adhering
to it. Use the 599B tip cleaner (provided with
the FM-202) or use a clean and moist clean¬
ing sponge (part no.A1519). Contaminants on
the tip have many deleterious effects, inciuding
reduced heat conductivity, which contribute to
poor soldering performance.
AIways clean the tip and coat it with fresh sol¬
der after use. This guards against oxidation.
Never allow the unit to idle at a high temperature
for extended periods. This will allow the tip to
become oxidized. Turn the power switch OFR
If it is to be out of service for several hours, it is
advisable to pull the power plug as well.
This procedure, if followed daily, will materially
add to tip life.
a. Set the temperature to 250°C (482'’F).
b. When the temperature stabilizes, clean the
tip (see 2, above) and check the condition of
the tip. If the tip is badly worn or deformed,
replace it.
c. If the solder plated part of the tip is covered
with black oxide, apply fresh solder, con-
taining flux, and clean the tip again. Repeat
until all the oxide is removed, then coat the
tip with fresh solder.
/(J^CAUTION:
NEVER file the tip to remove oxidesl __
d. Turn the power OFF and remove the tip, us-
ing the heat resistant pad. Set the tip aside
to cool.
e. Remaining oxides, such as the yellow dis-
coloration on the tip shaft, can be removed
with isopropyl alcohol.
