7. Operating Temperature
The most common soldering alloys used in the electronics industry consist of 60% tin and 40% lead.
The operating temperature of this type of solder is detailed below and can vary from manufacturer to
manufacturer. However, to meet RoHS requirements, these solders are no longer allowed and are
replaced by lead-free solders that require a working temperature which is ±30°C (54°F) higher.
Melting point
Normal Operation
Production Line Operation
A good joint is assured if the iron's operating temperature is set within the parameters suitable for the
type of solder being used. The solder will flow too slowly if the temperature is too low; if the
temperature is too high, the flux in the solder may burn which will give rise to billowing white smoke.
In turn, this will result in a dry joint or in permanent damage to the PCB.
8. Operating instructions
Refer to the illustrations on page 2 of this manual.
Verify whether the operating voltage of the unit is identical to that of the electrical supply.
GENERAL
•
Make sure the unit's power switch [6] is in the "OFF"-position.
•
Plug in the soldering iron [5]. Note that the connector has a notch so it only fits in one way. Do not
force.
•
Connect the AC power cord to the power connector [7]. Connect the other end to a suitable mains
outlet.
•
When applicable, connect an earth wrist strap to the earth jack [9] at the back of the station.
PARAMETER SETTINGS
•
Switch on the station [6]
•
Press the SET-button [2] and hold for at least 5 seconds until the display shows "— — —"
(flashing).Use the ▲-button [4] to enter the mode lock password "010" (default) and press the set-
button [2] to go into setup menu. A wrong password will return to normal working mode
(temperature indication).
•
In the setup menu, the display will show "F-0". Press the ▲[4]- or ▼ [3]-button to select modes. If
no button is pressed within 15 seconds the device will return to normal operation mode.
•
F-0: exit menu mode
Press the SET-button [2] when the display shows F-0 to exit the setup menu and return to
temperature indication.
•
F-1: password mode
When password mode is enabled, the user can not change the temperature settings on the
station unless he or she knows the password.
Press the set-button [2] once to enter password mode. Press the ▲[4]- or ▼ [3]-button to
change display between 000 and 100, with 000 indicating password mode disabled and 100
indicating password enabled. Press the set-button [2] to return to the setup menu.
•
F-2: temperature correction mode
Press the set-button [2] once to enter temperature correction mode. Press the ▲[4]- or ▼ [3]-
button to enter a correction factor for the temperature, e.g. when the display shows 300°C but
the actual temperature is only 290°C, add 10°C to the shown correction value.
Negative values are indicated with a minus in front. Press the set-button [2] to return to the
setup menu.
•
F-3: sleep/power off mode
Enabling sleep/power off mode will lower the irons' temperature after 20 minutes of inactivity.
After ±45 minutes of inactivity, the power to the iron is shut off.
Press the set-button [2] once to enter sleep/power off mode. Press the ▲[4]- or ▼ [3]-button
to change display between 000 and 100, with 000 indicating sleep/power off mode disabled and
100 indicating sleep/power off mode enabled. Press the set-button [2] to return to the setup
menu.
When in sleep mode, the temperature is lowered -> 200°C (392°F) and the display is flashing.
