Control Unit; Technical Data - Weller WDD 81V Manuel D'utilisation

1. Description

1.1 Control Unit

The microprocessor-controlled soldering station WDD 81V is part of a family of units that has
been developed for industrial production technology and for the service and laboratory sec-
tor. 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 corre-
sponding 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 50 ºC -
450 ºC (122 ºF - 842 ºF). 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.
1.2 Soldering tools
DSX 80: 80 W Desoldering Tool. Conical attachment system for the suction nozzle.
A wide range of suction nozzles enables solder to be removed from a wide
variety of solder joints. The tin collection container can be changed easily
without the need for tools. CSF desoldering plungers for the desoldering of
surface mounted components are available as accessories. Integrated finger
switch for activating the vacuum.
DSXV 80: 80 W Desoldering Tool. Conical attachment system for the suction nozzle.
In-line version (vertical work position). Tin collection container integrated
into the handle can be changed easily without the need for tools. Wide range
WDD81V 24
of CSF (SMD desoldering plungers) and suction nozzles. The vacuum is

activated by means of a finger switch.
LR 21: Our "standard" soldering iron. With a power of 50 watts and a wide spectrum
of soldering tips (ET series) this soldering iron can be used anywhere in the
electronics sector.
MLR 21: With its 25-watt power and slim design, this micro-soldering iron is especially
well-suited for fine soldering work with a low heating requirement.
WTA 50: The unsoldering tweezers WTA 50 were specially designed for unsoldering
SMD components. Two heating elements (2 x 25 watts), each with its own
temperature sensor, ensure constant temperatures at both ends.
LR 82: High-performance 80 watt soldering iron for soldering work with high heat
requirements. The soldering tip is attached by a bayonet catch to ensure
correct position when using different tips.
WSP 80: The soldering iron WSP 80 is characterized by its capacity for reaching the
soldering temperature quickly and precisely. Its slim design and heating power
of 80 watts makes universal usage possible - from extremely fine to high-
temperature soldering work. Work can be continued immediately after
switching soldering tips, since the temperature is reached again quickly.
See "Accessories" for additional tools.
