Description

2.1 Control Unit
The microprocessor-controlled desoldering station WDD 81V is part of a family of units that has been developed for industrial production technology and for the service and laboratory sector. The digital control electronics and a high- quality sensor and heat exchange system in the soldering tool guarantee precise temperature control at the soldering tip. The highest degree of temperature precision and optimal dynamic thermal behavior under load conditions is obtained by the quick and accurate recording of measured values in a closed control circuit. The soldering tools themselves are recognized automatically by the WDD 81V and the corresponding control parameters are assigned accordingly. The vacuum required for desoldering is generated by an internal maintenance-free compressed air converter and is activated via an integrated finger switch on the desoldering tool.
Various methods of equipotentially bonding the soldering iron bit, a zero voltage switch, and the anti-static design of the control unit and soldering tools supplement the high standard of the unit. The possibility of connecting an external input unit extends the functional diversity of this desoldering station. Additional functions including timing and interlocking can be realised using the WCB 1 and WCB 2 Input Units, available as optional extras.
The extended features of the WCB 2 Input Unit include an integrated temperature measurement unit and a PC interface. The required temperature can be set via 2 buttons (Up / Down) over the range from 50ºC – 450ºC (150ºF – 850ºF). Required and actual values are displayed digitally. A flashing red LED in the display indicates when the selected temperature is reached, this LED serves as an optical regulation monitor. The continuous illumination of the LED indicates that the system is warming up.

Technical Data

compressed air
Compressed Air Converter:| Air consumption 35 l / min; max. vacuum 55 kPa (8 psi)
Compressed Air Connection:| Compressed air hose of 6 mm (0.24″) external diameter
Equipotential Bonding (7):| via 3.5 mm jack bushing on the bottom of the unit. (State upon delivery: hard grounded, plug is not inserted)

Commissioning

Place the soldering tool in the holder. Insert compressed air hose with 6 mm outer diameter in the quick action coupling for the compressed air connection (12). Provide supply of compressed air with 400-600 kPa (57-87 psi) dry, oil- free compressed air. Plug the electrical lead from the soldering tool in the 7 pole socket (9) on the front panel and lock. Position the main filter (6) with the hose joint between the vacuum connection (8) and the vacuum connection on the desoldering tool. Check that the mains voltage matches that on the rating plate and that the mains switch (1) is in the off position. Plug the control unit into the mains (10). Switch on the unit at the mains switch (1). When the unit is switched on, a self-test is performed during which all the indicators (2) are illuminated. The temperature set (required value) and the temperature scale (ºC / ºF) are then briefly displayed. The electronics then switch automatically to the display of the actual value. The red dot (5) on the display (2) illuminates. This dot serves as an optical regulation monitor. Continuous illumination means that the system is heating up. Flashing indicates that the operating temperature has been reached. The vacuum necessary for desoldering is activated by the integrated finger switch on the soldering iron.
Setting the Temperature
Ordinarily the digital display (2) indicates the actual temperature. When the “UP” or “DOWN” button (3) (4) is operated the digital display (2) switches to the display of the required value currently set. The required value set (flashing display) can be changed in the corresponding direction by repeatedly pressing or holding down the “UP” or “DOWN” button (3) (4). The required value can be changed more quickly by holding the button down. Approx. 2 sec. after releasing the but- ton the digital display (2) switches automatically back to the actual value. It is not possible to make changes to the setting on a locked soldering station (LOCK).
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 (3) until ”ON” appears in the display. The setting is saved when the “UP” button is released. 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 setback function.
Vacuum delay
After the finger switch is released the vacuum remains active for approx. 2 seconds. Setting: When switching on, hold the ”DOWN” key (4) until ON or OFF appears in the display. The setting is saved when the “DOWN” button is released. Repeat this step to change.
Maintenance
To obtain good soldering results it is important to regularly clean the desoldering head. This includes emptying the tin collection container, replacing the glass tube filter, as well as checking the seals. Correct sealing of the front face of the
glass cylinder ensures full suction performance. Dirty filters affect the flow of air through the soldering tool. The main filter (6) (hose-mounted filter in the vacuum hose) should therefore be checked regularly and replaced if necessary.
Use a new original WELLER filter cartridge for this purpose. To clean the bore in the suction nozzle and the suction tube, use the cleaning tool (5 13 500 99).
The suction nozzles can be replaced quickly and easily with a short turning movement (approx. 45°).
Large deposits in the area of the cone will prevent the insertion of a new suction nozzle.
Deposits can be removed with the cleaning insert for the heating element cone.
Warning: Working without a filter will irreparably dama- ge the compressed air converter.
Figure: Cleaning Tool, Cleaning and Replacing the Suction Nozzle see page 95.

Equipotential bonding

The various circuit elements of the 3.5 mm jack bush (7) make 4 variations possible:

Instruction for Use

Different suction nozzles provide solutions for a wide range of desoldering problems. The correct tool for changing the suction nozzles is integrated in the cleaning tool. Press lightly against the heating element when inserting and locking the suction nozzles. It is important to use additional solder when desoldering. This ensures good suction nozzle wetting properties and improves the flow characteristics of the old solder. Ensure that the suction nozzle is perpendicular to the plane of the circuit board to achieve optimal suction performance. The solder must be completely molten. During the desoldering process it is important to move the component pin in a circular motion in the hole. If, after the desoldering process, the solder is not completely removed, the solder joint should be retinned before desoldering again. The selection of the right size of suction nozzle is important. As a rule of thumb: the internal diameter of the suction nozzle should match the diameter of the hole in the circuit board.
When heating the suction nozzle or soldering iron bit for the first time, wet with solder. This removes oxide layers and impurities that have formed during storage. Always ensure that the soldering iron bit or suction nozzle is well tinned during breaks in soldering and when placing in the holder. Do not use excessively aggressive fluxes.The desoldering station has been set up for a medium size suction nozzle or soldering iron bit. Temperature variations may occur if other bit shapes are used.
Important: Always ensure that the soldering iron bit is correctly seated.
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 (72°F) by input of a temperature offset.

• Setback:
  Reduction of the required temperature set to 150ºC / 300ºF (standby). The set- back time, the time after which the soldering station switches into standby mode, can be adjusted from 0-99 minutes. The set-back condition is indicated by a flashing actual value display. After a period equal to three times the set-back time, „Auto-Off“ is activated. The soldering iron is switched off (flashing dash on the display). The set-back or auto-off condition is ended by pressing a button or finger switch pressure. During this process the required value set is briefly displayed.

• 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. 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:
  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).
