Operation

On the front of the housing you will find the LC-Display, the temperature
preselect buttons 200°C, 300°C, 400°C, °C/°F and the UP/DOWN button. The
ON/OFF switch is situated at the back side of the housing.
After the power plug and the soldering iron have been plugged in and the
soldering iron has been placed in the stand, turn on the soldering station
with the ON/OFF switch (5).
In the display (1) you can see the current temperature in the upper line and
the preselected temperature in the lower line. The preselected temperature
can be set with the buttons "200°C", "300°C", "400°C" and "UP, Down". To
change the scale from °C to °F or vice versa, press the "°C/°F" button (6).
The scale in the display changes accordingly.
After you have pressed e.g. the "300°C" button, the selected temperature is
displayed as "SET 300°C" and the upper value to the right of "Temp."
climbs to 300°C. Meanwhile, at the right of the display "HEAT ON" and
"WAIT" will be displayed until the set temperature has been reached.
"WAIT" appears in the display while the temperature of the soldering iron is
increased or lowered. Temperature shifts of around 10°C around the set
value are normal.
With the "+ UP" and "DOWN –" button (7) you can set the temperature with
a resolution of 1°C or 2°F. To do so, briefly press the respective button.
The set temperature will increase or decrease by 1°C respectively 2 °F. If
you hold the button, the display will change in steps of 10°C / 18°F. When
the desired value is reached, just release the button.
Select the right temperature for every job to avoid cold soldering joints or
damaging delicate components or burning flux with excessive heat. Burnt
flux will cause weak joints.
In electronic circuitry
because colophony is not a conductor and can not cause a short-out on the
circuit board. Suitable solder can be ordered from
article number 46 01 13 (100 g spool with 1 mm diameter) and additional
colophony under the article number 88 53 68.
In electrics and electronics
used for less delicate work. Because flux can cause short-outs, residual flux
must be cleaned off with a cloth or a brush and alcohol. Otherwise, the flux
might cause a short-out.
Operation
solder with a colophony flux core is used. This is
solder without a flux core and separate flux is
