basic safety requirements of Directives 89/336/EEC and
73/23EEC.

2. Description

The soldering station WSF 81 D5/D8 is part of a family of
units developed for industrial production technology, repair
work and laboratory applications.
The soldering station contains an automatic filler wire feed
system. The diameters of filler wire that can be used are divi-
ded into two ranges and are determined by the type of sol-
dering iron used (0.5 mm – 0.8 mm for the WSF P5 soldering
iron and 0.8 mm – 1.5 mm for the WSF P8 soldering iron).
The feed unit and control unit can be stacked to save space.
The control unit contains digital electronics for controlling the
soldering iron control unit (Channel 1) and the feed control
unit (Channel 2). A microprocessor is used to obtain the best
possible temperature control response with different solde-
ring tools and precise feed control of the solder wire.
The temperature at the tip of the soldering iron (Channel 1) is
displayed digitally and can be smoothly adjusted within a
range of 50°C - 450°C. A blinking red LED in the display is
used as a visual control check to signal that the preselected
temperature has been reached. A continuous signal indica-
tes that the system is heating.
An integrated temperature monitoring circuit is used to eva-
luate various temperature states via a floating contact.
The feed unit contains the mechanical drive for the solder
feed and the soldering iron connection for the wire lead. A
wire holder that holds up to 1 kg of filler wire (max.) is also
included in the feed unit.
The mechanical drive adjusts automatically to the diameter
17
of the wire.
The WSF soldering iron features an ergonomic design and a
movable heating element. The very powerful 80W heating
element ensures that the soldering temperature is reached
quickly and precisely. The angle of the movable heating ele-
ment can be adjusted at approximately 40° after loosening
the locking bolt (20).
A general distinction is made between two types of solder
feed system:
Mode SFA - automatic:
In the operation mode SFA, the preset quantity of solder is
fed by the activation of the finger switch (optional: pedal
switch or external contact). The required amount of solder
can be smoothly adjusted from approx. 1 – 10mm. The feed
interval (Channel 2) is shown digitally.
Mode SFC - continuous:
In the operating mode SFC, the solder feed is activated for as
long as the finger switch (optional: pedal switch or external
contact) is activated. The speed of the feed rate can be
smoothly adjusted and is shown digitally on Channel 2.
Various equipotential bonding possibilities for the soldering
tip, zero voltage, and the antistatic design of the soldering
station complete the high standard of quality of this unit.
Additional functions and settings are possible at the solde-
ring station using the optional input devices WCB1 and
WCB2. An integrated temperature gauge and PC interface
are included in the expanded scope of function of the input
device WCB2.
3. Operation and settings
Channel selection
The digital display can be set to Channel 1 (temperature con-
trol) or Channel 2 (feed) by pressing the channel selection
key (7). The channel that is currently displayed is marked by
a red/orange LED above the socket (6) or (9).
If no keys have been activated, the unit will switch automa-
tically to Channel 1 after approx. 10 sec and show the actu-
al temperature.
Temperature setting (Channel 1)
If no keys have been pressed, the digital display (2) will show
the actual temperature. Pressing the "Up" or "Down" key (3)
(4) will switch the digital display (2) to the current setpoint
value. The setpoint value (blinking display) can be changed
in the desired direction by touching or continuously pressing
the "Up" or "Down" key (3) (4). If the key is pressed conti-
nuously, the setpoint value will change rapidly. The digital
