Caution!
Please read these Operating Instructions and the attached safety information carefully prior to initial operation. Failure to observe the safety regulations results in a risk to life and limb.
The manufacturer shall not be liable for damage resulting from misuse of the machine or unauthorised alterations.
The WELLER soldering station WSF 81 D5/D8 corresponds to the EC Declaration of Conformity in accordance with the basic safety requirements of Directives 2004/108/EC, 2006/95/EC and 2011/65/EU (RoHS).
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 divided into two ranges and are determined by the type of soldering 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 soldering 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 indicates that the system is heating.
An integrated temperature monitoring circuit is used to evaluate 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 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 element 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 soldering 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.
Operation and settings
Channel selection
The digital display can be set to Channel 1 (temperature control) 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 automatically to Channel 1 after approx. 10 sec and show the actual 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).
Technical specifications

Equipotential bonding: Initial state: hard grounded
If the key is pressed continuously, the setpoint value will change rapidly. The digital display (2) will automatically return to the actual value approximately 2 seconds after the key is released.
Standard setback
If the soldering tool is not used within a period of 20 minutes the
temperature will be automatically reduced to a standby temperature of 150 °C
(300 °F). After three setback periods (60 min.) the ”AUTO OFF” function will
be activated and the soldering iron will be switched off.
Activating the standard setback function: When switching on the unit press the ”UP” button until ”ON” appears in the display. Use the same process to switch the unit off. ”OFF” will appear in the display (state upon delivery).
The use of very fine soldering tips may have a negative effect on reliable function.
Feed setting (Channel 2)
After switching to Channel 2, the digital display (2) will show the speed in
the SFC mode or the feed period in the SFA mode. This value can be changed in
the desired direction by touching or continuously pressing the ”Up” or ”Down”
key (3) (4). If the key is pressed continuously, the setpoint value will
change rapidly. If no keys are pressed, the unit will automatically switch to
Channel 1 after approximately 10 seconds and show the actual temperature.
Setting range:
SFA mode – feed period (solder) 1 – 300 (10ms intervals)
SFC mode – speed
10% – 100%
Rapid feed:
Simultaneous pressing of the ”UP” and ”DOWN” keys advances the solder wire at
max. speed (100%). Recommended for advancing the filler wire after the solder
roll is replaced.
SFA / SFC mode switch:
Press the channel selection key (7) continuously and set the desired mode with
the ”UP” key (3). The new operating mode will appear on the display.
Adjusting the temperature window
Press the channel selection key (7) and ” Down ” (4) simultaneously. The
blinking value (in °C/°F) of the current temperature window will appear on the
display (factory-set to ”000”).
The factory setting ”000” means:
Temperature monitor circuit has been switched off and the unpowered contact
(16) is always low-resistant.
°C display
The setting ” 001 – 099 ” corresponds to the following: Size of the
temperature window + – 1°C to + – 99°C
°F display
The setting ” 001 – 178 ”corresponds to the following: Size of the temperature
window +- 1°F to +-178°F
Unpowered contact (potential independence)
If the actual temperature of the soldering tool is within the temperature
window (tolerance width), the contact (16) will be low-resistant. If the
temperature is outside the temperature window, this will be indicated on the
display (2) as ”HI” (temperature too high) or ”LO” (temperature too low) at 2
second intervals. The contact (16) is high-resistant.
The transistor output of an optocoupler functions as the unpowered contact of the unit. Care must therefore be taken to note the polarity of the voltage to be applied.
PLUS (+) at Pin 2
MINUS (-) at Pin 3
This contact can be loaded with max. 24V / 20mA
External input device WCB 2 (optional)
The following functions are available when using an external input
device:
-
Offset:
The actual temperature of the soldering tip can be changed by + – 40°C by entering a temperature offset -
Setback:
Reduction of the setpoint temperature to 150°C /300°F (standby). The setback period, after which the soldering station switches to the standby mode, can be adjusted from 0 – 99 minutes. The setback state is indicated by a blinking display of the actual value. After three setbacks, the AUTO OFF function will be activated and the soldering tool will switch off (blinking dash on the display). The setback state or AUTO OFF ends after pressing a key or the finger switch. At this time the setpoint will be displayed briefly. -
Lock:
Locking of the setpoint temperature and temperature window. No changes can be made to the soldering station settings after locking. -
°C / °F:
Switching the temperature display from °C to °F and vice versa. Pressing the ”Down” key when switching the unit on will show the current temperature version. -
Window:
Limitation of the temperature range to max. ±99 °C based on a locked temperature resulting from the ”LOCK” function. The locked temperature represents the median point of the adjustable temperature range. For units with a floating contact (optocoupler output) the ”WINDOW” function is used to adjust a temperature window. If the actual temperature is within the temperature window the floating contact will be enabled (optocoupler output). -
Cal:
Factory setting FSE (reset of all adjusted values to 0, temperature setpoint value: 350°C/660°F -
PC interface:
RS232 (WCB 2 only) -
Temp.gauge:
Integrated temperature gauge for the rmocouple Type K (WCB 2 only)
Maintenance and care
If the feed rate is irregular, the drive wheel can be cleaned with a brass
brush. First remove the control unit from the feed unit. Push back the cover
of the feed unit to access the feed unit. Lift the drive wheel and clean.
Instructions for care of the WSF P5/P8 / WP / WSP soldering gun (heating element, tip receptacle and soldering tip) Please clean the heating element depending on how much you use the soldering gun.
Cleaning the heating element:
Remove any dirt and old solder from the tip of the gun. Remove the tip
receptacle by undoing the knurled nut/tip receptacle. Take care not to crush
the tip receptacles during removal (in order to avoid damaging the heating
elements). Use wire brush T0051382799 for cleaning Cleaning set WDC 2
T0051512699 Cleaning set WDC T0051512799.
Care of the soldering tip:
After lead-free soldering we recommend that you always rewet the soldering tip
with tin solder before putting the soldering gun back into the stand. Always
use our steel wool for WDC 2 T0051512599 and WDC T0051512499 to clean the
soldering tip. We recommend using Tip Activator (T0051303199) for non-wettable
soldering tips.
Start-up
Establish the electrical connection between the feed unit and the control unit. Insert plug (12) into socket (6).
Connect the soldering iron connections to the control unit and feed unit. Insert the electrical connecting plug for the soldering iron into the 7-pin socket (9) of the control unit, and lock into place. Fully insert the wire lead into the connection element (13) of the feed unit and fasten with the clamping screw (17).
Place the soldering iron in the storage tray.
Verify the correct system voltage and connect the control unit to the mains (14). Switch on the unit (1).
Install solder roll.
Remove knurled nut (19) on the solder roll holder. Place the solder roll on
the shaft so that the wire unrolls downwards. Secure the roll with the knurled
nut and push the end of the wire into the inlet port (18).
Pressing the ”UP” and ”DOWN” keys simultaneously will cause the drive to catch the solder wire and transport the wire at maximum speed. Continue to advance the solder wire until it appears at the soldering iron nozzle (22).
In the event that the solder wire is not caught by the drive, the cover of the feed unit can be pushed back to access the drive unit. Therefore turn both locking pins (10) counter clock wise (ccw) approx. 90° until release.
Carry out adjustments to the units as described in the section ”Operation and settings”.
Equipotential bonding
Four different versions can be obtained by different wiring of the 3.5mm jack bushing (8).
Hart grounded: No plug (state upon delivery)
Equipot. bonding (impedance:
0 ohms): With plug, equalizing conductor on central contact
Floating: With plug
Soft grounded: With plug and soldered resistor. Grounding via the
selected resistance.
Soldering instructions
For initial heating coat the soldering tip (tip can be coated selectively)
with solder. This removes oxide deposits and impurities from the soldering tip
that occur during storage. During soldering breaks and before storing the
soldering iron, always ensure that the soldering tip is well coated with
solder. When using very low activated flux agents (no clean), the use of ”Tip
Activator” is recommended to maintain the coating.
Dirt, foreign material or damage may not affect the transition between the
heating element/sensor and the soldering tip.
This will compromise the precision of the temperature control.
Important: always ensure the soldering tip fits properly.
Keep the heat-conducting surfaces of the heating element and soldering tip
clean.
The hot soldering tip may not come in contact with the cleaning sponge or
plastic surfaces.
These soldering units have been adjusted for use with a medium-sized soldering nozzle or jet. Deviations can occur as a result of changing the tip or using other tip shapes.
