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.
