Setting the temperature
The digital display (2) shows the actual value temperature. 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.

3. Equipotential bonding

The various circuit elements of the 3.5 mm jack bush 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 resistance. Grounding via set resistance
value.

4. Instructions for use

For initial heating, coat the selective tinnable tip with solder. This removes any oxidation or
dirt on the tip which may have occurred during storage. During pauses between 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 soldering 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.
WSD_80WS.D50 23
External input unit WCB 1 and WCB 2 (optional)
The following functions are possible when using an external input unit.
Offset: The real temperature of the soldering iron can be changed by ± 40 °C by
input of a temperature offset.
Setback: Reduction of the setpoint temperature to 150 °C (standby). The setback
time can be set at 0-99 minutes after the soldering station has switched
to standby mode. After a period equal to three times the set-back time,
the "Auto Off" function is activated. The soldering iron is switched off
(flashing dash on the display).
Lock: Locking the setpoint temperature. Settings cannot be changed after the
soldering station has been locked.
°C/°F: Switching the temperature display from °C to °F, and vice versa.
Window: Setting a temperature window (only with control units with optical coupler
output). If the actual temperature is within the temperature window, a
potential-free contact (optical coupler output) will be switched through.
Cal: Re-adjustment of the soldering station (WCB 2 only).
PC interface: RS232 (WCB 2 only).
Temp. gauge: Integrated temperature gauge for thermal element Type K (WCB 2 only).

5. Safety instructions

The manufacturer assumes no liability for uses other than those described in the operating
instructions, or for unauthorized alterations.
These operating instructions and warnings should be read carefully and kept in an easily
visible location in the vicinity of the soldering iron. Non-observance of these warnings can
result in accidents, injury or risks to health.
The WELLER soldering stations WSD 80 and WSD 50 are in compliance with the EC Declaration
of Conformity in accordance with the basic safety requirements specified by Directives 89/
