1. Inspect and Clean the Tip
CAUTION: Never file the Tip to remove
oxide.
• Set the temperature to 250'C(482"F).
• When the temperature stabilizes, clean the
tip with the cleaning sponge and check the
condition of the tip.
• If there is black oxide on the solder-plated
portion of the tip, apply new solder
(containing flux) and wipe the tip on the
cleaning sponge.
Repeat until the oxide is completely
removed. Coat with new solder.
• If the tip is deformed or heavily eroded,
replace it with a new one.
2. Calibrating the Iron Temperature
The soldering iron should be recalibrated
after changing the iron, or replacing the
heating element or tip.
• Connect the cord assembly plug to the
receptacle on the station.
• Set the temperature control knob to 400'C
(750·F). .
• Turn the power switch to "ON" and
wait
until the temperature stabilizes. Remove the
CAL pot plug.
• When the temperature stabilizes, use a
straightedge (-) screwdriver or small plus
(+)
screwdriver to adjust the screw
(marked CAL at the station) Until the tip
thermometer indicates a temperature of
400·C(750·F). Turn the screw clockwise to
increase the temperature and
counterclockwise to reduce the temperature.
Replace the CAL pot plug.
3. Tips
The tip temperature will vary according to the
h
Shape of the tip. The preferred method of
adjustment uses a tip thermometer (See
"Calibrating the Iron Temperature").
WARNING!
Disconnect the power plug before
servicing. Failure to do so may result
ill
electric shock.
If the power cord is damaged, it must be
replaced by the manufacturer, its service
agent or similarity qualified person in
order to avoid personal injury or damage
to the unit.
Problem 1.
The heater lamp does not light up.
[Check 1.]
Is the power cord and/or connecting plug
disconnected?
• Connect it.
[Check 2.]
Is the fuse blown? . .
• Determine why the fuse blew and eliminate
the cause, then replace the fuse.
a.1~the inside of the iron short-circuited?
b. Is the grounding spring touching the
heating element?
c. Is the heating element lead twisted and
short-circuited?
Problem 2.
The heater lamp lights up but the tip
does not heat up.
[Check 3.]
Is the soldering iron cord broken?
• Refer to "Checking for breakage in the cord
assembly."
[Check 4.]
Is the Heating Element broken?
• Refer to "Checking for breakage in the
heating element."
