Weller WRS 1002, Operating Instruction

3

1. Description

The WRS 1002 is a solder / desolder unit, which has an outstanding range of
functions. All the soldering attachments listed in the accessories list (25 W-150 W)
may be connected alternately. Adjustment of the different soldering devices is not
necessary since the integrated microprocessor automatically recognises the
connected device and optimises the relevant parameters for optimum control. The
temperature is controlled digitally. The required process parameters for temperature
and air are entered via three user-friendly buttons (Up, Down, Air). Set value and
actual value are displayed digitally.

With the hot air pencil temperatures of 150°F – 1000°F can be realised, on the
connection of a soldering iron or desoldering iron the adjustment range is
automatically limited to max. 850°F. The achievement of the pre-selected temperature
is indicated by a flashing dot on the display. Continuous illumination signifies that the
system is warming up. The air for the hot air pencil and the vacuum for the
desoldering iron are generated using an internal pump and activated using a
microswitch on the soldering tool. 

Various timing functions for the soldering tools and a lock function (keylock) for the
process parameters can be set using the WCB1 and WCB2 external data input units. 

A wide range of products including hot-air jets, suction nozzles and soldering bits are
available which allow many different soldering tasks to be undertaken.

The metal casing is anti-static coated. The soldering tip is hard grounded.

2. Installation

Place the soldering bit in the safety holder. Connect the connecting cable on the
control instrument.

Plug in, and latch the electrical connector on the 7 terminal connector (1).

For the hot-air pencil: Push the air hose onto the „air“ nipple (10).

For desoldering: Push the vacuum hose onto the „vac“ nipple (9).

Attention: To avoid injury, the vacuum hose of the desolderer should never be
connected to the „air“ nipple.

Check whether the mains voltage matches the information on the rating plate. In the
case of correct mains voltage, connect the controller to the mains (12). Switch on unit
at the mains switch (6). When the unit is switched on a self-test is performed during
which all display elements (2) are operated briefly. The electronics then switches
automatically to the temperature and air flow rate set. The red dot on the display (3)
illuminates. This dot is used as visual check on the regulation. Continuous
illumination signifies that the system is warming up. Flashing signals that the pre-
selected temperature has been reached. The temperature display (2) indicates the
actual value. 

The built-in pump is started using a microswitch that is integrated in the handle.

The supply unit uses a pressure gauge (5) to display the vacuum. The degree of
contamination of the filter cartridge (9) is displayed here.

Attention: The pump motor is fitted with a ventilator to ensure that the instrument
remains cool. There must be sufficient air supply for this ventilator.

Setting the temperature
In general the digital display (2) shows the actual temperature. By pressing the „Up“
or „Down“ button (4) (7), the display (2) switches to the set value. This value can then
be increased or decreased by pressing the „Up“ or „Down“ button (4) (7) respectively.
