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.
leaded solder
lead-free solder
Melting point
215 °C (419 °F)
220 °C (428 °F)
Normal operation
270-320 °C (518-608 °F)
300-360 °C (572-680 °F)
Production line operation
320-380 °C (608-716 °F)
360-410 °C (680-770 °F)
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.

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.
8.1
General
1.
Make sure the station is switched off (power switch
[5]
in the “0” position).
2.
Connect the AC power cord to a suitable mains outlet.
3.
When applicable, connect an earth wrist strap to the earth connection
[6]
at the bottom of the
station.
8.2
Parameter Settings
1.
Switch on the station
[5]
.
2.
Press and hold the SET button
[2]
for at least 5
seconds until “—
—
—” flashes on the display. Use
the
▲
button
[4]
to enter the password “010” (default) and press the SET button
[2]
to enter the
setup menu. An incorrect password will return the station to normal operation mode (temperature
indication).
The display shows “F
-
0”.
3.
Press the
▲
[4]
or
▼
[3]
button to select a mode. If no button is pressed within 15 seconds, the
device will return to normal operation mode.
o
F-0
: exit menu mode
Press the SET button
[2]
when the display shows F-0 to exit the setup menu and return to
normal operation mode.
o
F-1
: password mode
If password mode is enabled, you cannot change the temperature settings on the station unless
you know the password.
Press the SET button
[2]
once to enter password mode. Press the
▲
[4]
or
▼
[3]
button to
switch between 000 (password mode disabled) and 100 (password enabled). Press the SET
button
[2]
to return to the setup menu.
o
F-2
: temperature correction mode
If the displayed temperature deviates from the actual temperature of the tip, you can calibrate
the display here.
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 (
–
99 °C ~ +99 °C;
–
210 °F ~ +210 °F).
For example, if the display shows 300 °C but the actual temperature is only 290 °C, add 10 °C
to the shown correction value. If the current correction value is 00, change it to 10. If the
current correction value is
–
20, set it to
–
10. If the current correction value is 20, set it to 30.
Negative values are indicated with a minus in front. Press the SET button
[2]
to return to the
setup menu.
o
F-3
: unit of temperature
Press the SET button
[2]
once to enter temperature mode. Press the
▲
[4]
or
▼
[3]
button to
switch between °C and °F. Press the SET button
[2]
to return to the setup menu.
