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.
4. 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.
