3. Starting
Assemble soldering iron rest (see exploded
drawing).Place the soldering iron in the safety rest. Insert
the soldering iron plug into the connection bush (6) of
the control unit and lock by turning to the right. Check
that the power supply corresponds to the specifications
on the name plate and that the power switch (1) is in the
OFF position. On version that can be switched, set the
voltage on selection switch (9) (set in the factory to 240
V ). Connect the control unit to the power supply. Set the
temperature at the rotary potentiometer (3). Switch on
unit at the supply switch (1). Green LED (2) will illumina-
te. This LED functions as the optical regulator. Constant
illumination means that the system is overheating. The
blinking light signals that the operating temperature has
been reached.
Setting the temperature
The digital display (2) shows the actual value temperatu-
re. By pressing the UP or DOWN key (3, 4) the digital
display (2) switches to the setpoint. The setpoint can be
changed by tapping or by firmly pressing the UP or
DOWN button (3, 4) in the desired
direction. Pressing the button will change the setpoint
quickly. The digital display (2) returns automatically to
the actual value approximately 2 seconds after releasing
the button.
Maintenance
The transition between the heating element / sensor and
the tip of the soldering iron may not come in contact with
dirt, foreign particles or become damaged, since this
affects the precision of the temperature control.
4. Equipotential bonding
The various circuit elements of the 3,5 mm jack bush (5)
make 4 variations possible:
Hard-grounded:
No plug (delivery form)
Equipotential bonding:
With plug, equalizer at center
contact (impedance 0 ohms)
Potential free:
With plug
Soft-grounded:
With plug and soldered resi
stance.
Grounding with set
resistance value.
5. Instructions for use
For initial heating, coat the selective tinnable tip with sol-
der. This removes any oxidation or dirt on the tip which
may have occurred during storage. During pauses bet-
ween soldering and before storing the soldering iron,
ensure that the tip of the soldering iron is well coated. Do
not use aggressive fluxing agents.
Note: Always ensure the proper position of the solde-
ring iron tip.
These soldering irons have been adjusted for an average-
size tip. Deviations can occur due to exchanging of the tip
or using other tip designs.
