Equipotential Bonding; Instructions For Use - Weller WSD 151 Operating Instructions Manual

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.
Standard setback:
Setting back the set temperature to 150°C. The setback time, which follows the
switching of the soldering station to standby mode, is 20 minutes. After three setback
times (60 minutes) the "Auto-off" function is activated. The soldering tool is switched
off (blinking line on the display).
Setting: When switching on, hold the "UP" key (3) until ON or OFF appears in the
display. Repeat this step to change.
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 (6) 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.
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: 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.
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).
