heating element.
Desoldering iron:
When desoldering, it is important to use additional solder wire. This gives good wetting of the
suction nozzles and better flow properties of the old solder. Care should be taken that the
suction nozzle is perpendicular to the circuit board in order to achieve the optimum suction
power. The solder must be completely fluid. During desoldering it is important to move the
connecting pin of the component in circular movements in the hole. If the solder is not
completely removed after the suction process, the soldered joint should be newly tinned
before the next attempt at desoldering.
It is important to choose the correct size of suction nipple. Rule of thumb is that the inner
diameter of the suction nozzle should be the same as the diameter of the circuit board hole.
Pump over-run when using the vacuum function
When desoldering, the vacuum function can be set to continue running (1 sec.). The factory
setting does not active this over-run.
Switching on the pump over-run
Turn of the instrument. Press the „up" and „down" buttons when turning the instrument
back on, until the self-test is finished. A „-1-" will appear on the display. Release the buttons.
Switching off the pump over-run
Turn of the instrument. Press the „up" and „down" buttons when turning the instrument
back on, until the self-test is finished. A „OFF" will appear on the display. Release the buttons.
Soldering:
When heating up for the first time, the soldering bit should be wetted with solder. This removes
oxide layers and contamination which might have occurred during storage. When pausing
between soldering, and before putting the soldering iron down, ensure that the bit is well
tinned. Do not use very aggressive flux.
Attention: Never use the soldering iron without a bit, as this will damage this
heating element and temperature sensor.

General: The soldering irons are set for medium bits and nozzles. Deviations caused by
changing the bits, or by using other types of bits can occur.

5. Safety information

The manufacturer accepts no liability for usage other than that specified in the operating
instructions, nor for any unauthorised modifications.
These operating instructions and the warning instructions they contain should be read carefully
and kept in a clearly visible place adjacent to the soldering unit. Failure to adhere to warning
instructions can cause accidents and injuries or be detrimental to health.
The WELLER solder / desolder unit WMD 1S complies with the EC certificate of conformity in
accordance with the basic safety standards of guidelines 89/336/EEC and 73/23/EEC.
