Operation Filter change
Replacing electrical replacement parts| Technical trainees under the guidance and supervision of a trained expert

Starting up the device

Caution!
Please adhere to the operating instructions of the connected devices.

Put the tool into operation as described in the chapter „Placing into operation“.

Check to see if the mains voltage matches the ratings on the nameplate.

Make sure the machine is switched off before plugging in.
After the device has been switched on, the microprocessor carries out a self- test in which all the segments are briefly in operation.

Soldering and disordering

Carry out soldering work as directed in the operating instructions of your connected soldering tool.

Handling the soldering tips

• Coat the selective and tinnable soldering tip with solder when heating it up for the first time. This removes oxide coatings which have formed during storage and impurities from the soldering tip.
• Make sure that the soldering tip is well coated with solder during breaks between soldering work and prior to storage of the device.
• Do not use aggressive fluxing agents.
• Always make sure that the soldering tips are fitted properly.
• Select as low a working temperature as possible.
• Select the largest possible soldering tip shape for the application.
• Rule of thumb: the soldering tip should be roughly as large as the soldering pad.
• Coat the soldering tip well with solder to ensure that there is efficient heat transfer between the soldering tip and the soldering area.
• Prior to extended breaks between soldering work, switch off the soldering system or use the Weller function to reduce the temperature when the soldering equipment is not in use.
• Coat the tip with solder prior to storage if you do not intend to use the soldering iron for an extended period of time.
• Apply solder directly to the soldering area, not to the soldering tip.
• Change the soldering tips using the designated tool.
• Do not apply mechanical force to the soldering tip.

Notice
The control units have been adapted to hold a medium-sized soldering tip. Discrepancies may occur if the tip is changed or a different shaped tip is used.

Overload cut-out

To avoid overloading the station, power output is automatically reduced in the event of an overload.

Equipotential bonding

Four variants are possible by connecting the 3.5 mm jack socket differently

resistor.

Carrying out a firmware update (WR 3M)

Notice
The control unit is equipped with a Mini USB port. To use the USB port, Weller provides software on so you can carry out a software update („Firmware Updater“) on your control unit.

Care and maintenance

Warning!
<Before doing any work on the machine, pull the plug out of the socket.

Warning!
Use original replacement parts only.

Warning! Risk of burns

• Only replace solder tips when cold
• Replace and clean suction nozzles only when hot and using the suitable tool
• Only replace hot air nozzles using the suitable tool
• Only clean or replace solder collection tubes when cold

Clean the operator panel, if dirty, using a suitable cleaning cloth

Filter change
Check the filter regularly for contamination, and replace it if necessary.

Warning!
Failure to use a filter will cause irreparable damage to the vacuum pump.

• Check before starting soldering whether a main filter is inserted.

Contaminated filters must be treated as special waste.

Dispose of replaced equipment parts, filters or old devices in accordance with the rules and regulations applicable in your country. Wear suitable protective gear

Parameter menu

Standby Temp. (STANDBY)

After activating the Setback function or after pushing the ECO button (WR 2), the temperature is automatically reduced to Standby temperature. The display flashes the actual temperature. <STANDBY appears on the display.

Setback time (SETBACK)

If the soldering tool is not in use, the temperature is reduced to Standby temperature on expiration of the preset Setback time.
SETBACK appears on the display.
To exit Standby mode, push the „UP / DOWN“ buttons or ECO (WR 2).
Depending on the tool in use, the finger switch or the safety rest deactivates Standby mode.

immediately reduced to standby level.
1-999 min| Setback time Individually adjustable

AUTO OFF time (automatic switch-off time)

If the soldering tool is not in use, the soldering tool is switched off on expiration of the AUTO-OFF time.

The actual temperature flashes on the display and serves as residual-heat indicator. „OFF“ appears on the display. A flashing dash appears on the display below 50 °C (122 °F

Temperature-Offset (Offset)

The actual soldering-tip temperature can be adapted by entering a temperature offset around ± 40 °C (± 72 °F).

Temperature window (WINDOW)

Starting from a set, locked temperature, it is possible to set a temperature window of ± 1-99 °C (±1 180 °F) using the WINDOW function. To use the WINDOW function, the repair station must be interlocked

Temperature units (°C/°F)

Max. hot air duration (HAP On)

The on-time of the hot air flow of the HAP 200 can be limited in increments of 1 to between 0 and 60 sec. The set time is then identical for all 3 channels

The factory default is s („OFF“), i.e. air flows only as long as the button on the hot air tool or the optional footswitch is pressed

Vacuum pre-feed (VAC On)

In order to prevent the pump from starting prematurely or to ensure a defined soldering-joint preheating time, it is possible to set an ON delay.

Vacuum run-on (VAC Off)

lock function

After the lock has been activated, only the following buttons on the soldering station are enabled:

WR 2: ┌ 1 ┐, ┌1·2┐,┌ 2 ┐, ECO , AIR

WR 3M: ┌ 1 ┐, ┌ 2 ┐, ┌ 3 ┐ ┌1·2·3┐, Pick Up , AIR

All other settings are disabled until the repair station is unlocked again.

Notice

If you want only one temperature value to be selectable, the control keys fixed temperature keys) must be set to the same temperature value

Pressure gauge threshold (LEVEL)

This function can be used to define the maintenance interval of the disordering tool. This is done by setting the value in mbar at which the electric pressure gauge issues a warning signal when the intake system is contaminated (LED of the vacuum pump switches from green to red). The set value is dependent on the suction nozzles used. Adjustable -400 mbar to -800 mbar factory setting -600 mbar

1. The system (tips and filter) must be free.
2. Select the menu item „Pressure gauge threshold“ in the menu.
3. Set the „Pressure gauge threshold“ pressure value with the UP or DOWN button. The status LED switches back and forth between red and green. Use the UP button to increase vacuum by 50 to 80 mbar, then pinch the vacuum tube and check whether the LED switches from green to red.

Station code (Remote ID)

WR 3M
A station code (Remote ID) can be assigned to each station, allowing the station to be clearly identified via the USB port.

Calibration (Factory Calibration Check FCC)

You can use the FCC function to check the temperature precision of the repair station and even out possible deviations. For this purpose, the soldering-tip temperature must be measured with an external temperature meter and a temperature measuring tip assigned to the soldering tool. The corresponding channel must be selected prior to calibration.
