Cleaning
Clean the tip regularly with a cleaning sponge, as oxides and carbides from the solder and flux can form
impurities on the tip. These impurities can result in defective joints or reduce the tip's heat conductivity.
When using the soldering iron continuously, be sure to loosen the tip and remove all oxides at least once
a week. This helps prevent seizure and reduction of the tip temperature.
When not in use
Never leave the soldering iron sitting at high temperature for long periods of time, at the tip's solder plating
will become covered with oxide, which can greatly reduce the tip's heat conductivity.
After use
Wipe the tip clean and coat the tip with fresh solder. This helps prevent tip to oxidation.
Maintenance
Inspect and clean the tip
1. Set the temperature to 250°C (482°F)
2. When the temperature stabilizes, clean the tip with the cleaning sponge and check the condition of the
tip.
3. If there is black oxide on the solder-plated position of the tip, apply new solder (containing flux) and
wipe the tip on the cleaning sponge. Repeat until the oxide is completely removed, and coated with new
solder.
4. If the tip is deformed or heavily eroded, replace it with a new one.
CAUTION:
Never file the tip to remove oxide.
Calibrating the iron temperature
The soldering iron should be recalibrated after changing the iron, or replacing the heating element or tip.
1. Connect the cord assembly plug to the receptacle on the station.
2. Set the temperature control the knob to 400°C (750°F).
3. Turn the power switch to 'ON' wait until the temperature stabilizes, Remove the CAL pot plug.
4. When the temperature stabilizes, use a straight-edge(-) 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.
Tips
The tip temperature will vary according to the shape of the tip. The preferred method of adjustment uses a
tip thermometer. (See calibrating the iron temperature.)
