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 desoldering

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 shapedtip 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.
