4 Device description

The Weller WR 3ME is a versatile repair station for making professional repairs to latest-technology electronic subassemblies in industrial production engineering and in the repair and laboratory fields. The WR 3ME has 3 independent channels for simultaneously operating 3 soldering tools. Precise temperature control performance at the soldering tip is guaranteed by the digital control electrotechnology together with superior-quality sensor and heat-transfer technology. High-speed measured-value acquisition provides for maximum temperature precision and optimum dynamic temperature performance in load situations. The temperature can be set to any value within the range from 50 °C to 550 °C (150 °F – 999 °F) depending on which tool is connected. Setpoint and actual values are displayed in digital form. Three temperature buttons are used to select fixed temperatures directly. The optical control indicator flashes ("“ symbol in the display and additional green LED) to indicate when the preselected temperature has been reached. The Weller WR 3ME repair station offers the following additional functions:  Automatic tool detection and activation of corresponding control

parameters

 All Weller tools incl. HAP 200 can be connected

(WX tools excluded)

 Digital temperature control  Option of inputting offset values  Programmable temperature reduction (setback)  Standby and lock functions  Installed heavy-duty pump  Antistatic device design in accordance with ESD safety  Different equipotential-bonding possibilities on the device

(standard configuration)

 Customer-specific calibration function  USB port for control, evaluation and documentation via PC

WARNING!

Risk of injury due to incorrectly connected vacuum hose.

If the vacuum hose is incorrectly connected, hot air and liquid solder can escape when the unsoldering bit is actuated and cause injuries.

 Never connect the vacuum hose to the "Air“ nipple!

Note

If you are using an HAP 200, this can only be connected to channel 1! The maximum output power is limited to 360 watts.

USB port The control unit is equipped with a mini USB port (24). For the

purpose of using the USB port, Weller software is available on a CD with which you

 can carry out a software update ("Firmware Updater“) on your

control unit and

 can remote-control the control unit and graphically display, store

and print temperature curves ("Monitor Software“).

Equipotential bonding 4 variants are possible through connecting the 3.5 mm pawl

socket (27) differently:

 Hard earthed/grounded: without connector (delivery status)  Equipotential bonding: with connector, bonding lineat central

contact

 Floating: with connector  Soft earthed/grounded: with connector and soldered resistor.

Earthing/grounding via the selected resistor

5 Starting up the device

1. Carefully unpack the device.

2. Connect the soldering tools as follows:

- Connect the hot-air pencil (HAP) with air hose to "Air“

nipple (14) and insert with the attachment plug in connection socket ┌ 1 ┐, ┌ 2 ┐ or ┌ 3 ┐ (15) of the repair station and lock by turning clockwise slightly. The HAP 1 hot-air pencil can only be connected with the air-hose adapter.

- Connect the unsoldering tool with vacuum hose to "Vac“

nipple (13) and insert with the attachment plug in connection socket ┌ 1 ┐, ┌ 2 ┐ or ┌ 3 ┐ (15) of the repair station and lock by turning clockwise slightly.

- Insert the soldering tool with attachment plug in connection

socket ┌ 1 ┐, ┌ 2 ┐ or ┌ 3 ┐ (15) of the repair station and lock by turning clockwise slightly.

3. Place the soldering tools in the safety holder.

4. Check whether the mains supply voltage matches that indicated on the rating plate and whether mains power switch (12) is off.

5. Connect the control unit to the mains supply (26).

6. Switch on the device at mains power switch (12).

8-22 WR 3ME

Note

The display switches automatically to the channel to which a tool has been newly connected, the finger switch has been pressed or the tool has been removed from the switching holder. This function can be deactivated in the special functions menu 2 (see "Deactivate / activate automatic channel change" on page 18).

After the device has been switched on, the microprocessor carries out a self-test in which all the segments are briefly in operation. Then the electronics switches automatically to the basic temperature

setting of 350 °C for all channels and 50 % for the "Air" setting.

Green LED (2) lights up when activated channels are being used:  LED lit green constantly indicates that the connected tool is being

heated up.

 LED flashing green indicates that the preselected tool temperature

has been reached.

Active channels are indicated in the display with a triangle (21) and a lightning symbol (20).

6 Operating the device

6.1 Selecting a channel, switching on or off

1. Press one of the buttons ┌ 1 ┐, ┌ 2 ┐ or ┌ 3 ┐ to select one of the three channels. The display shows the setpoint temperature of the selected channel and - in smaller script - the permanently programmed temperatures.

- Or Tap on the ┌ 1·2·3 ┐button until the desired channel is displayed. The current tool temperature then appears in the display. The status with the corresponding setpoint temperature is also displayed in the lower area. The selected channel is indicated by a triangle (20) in the display and by a red-lit LED (1) on the device.

2. Press the UP and DOWN buttons simultaneously until three dashes "- - -“ appear in the display.

3. Release the buttons. If the channel is now deactivated, "OFF“ appears in the display. If the channel is activated, the current actual temperature appears in the display.

Stored data are not lost when a channel is switched off.

WR 3ME 9-22

Note

Assigning a low "Setback“ temperature to a temperature button offers the possibility of manual temperature reduction when the soldering bit is not in use.

6.2 Setting the temperature
