6.2 Soldering
Handling soldering tips
- Coat the tin-plated soldering tip with solder when
heating the iron for the first time to remove any oxide
films or impurities from the soldering tip that have
accumulated during storage.
- During pauses between soldering and before storing
the soldering iron, ensure that the soldering tip is
wellcoated.
- Do not use aggressive fluxing agents.
- Always ensure that the soldering tip is seated properly.
- Select the lowest possible working temperature.
- Select the largest possible soldering tip shape for the
application.
Rule of thumb: approx. as large as the component
or mounting surface on the printed circuit board
- Coat the soldering tip well to ensure efficient heat
transfer between the soldering tip and soldering point.
- Switch off the system if you do not intend to use the
soldering iron for longer periods or activate the
Weller temperature reduction function.
- Coat the tip before placing the soldering iron in the
holder.
- Apply the solder directly at the soldering point, not on
OFF
the soldering tip.
- Change the soldering tip using an appropriate tool.
- Do not subject the soldering tip to physical force.
Note:
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.

6.3 Switching off the device

Press the + and – button until "OFF" appears on the
display
Note
If you do not intend to use the soldering iron for longer
periods, set the disconnecting switch for battery (6) to "O".
Make sure that the battery is charged at least 50 %, see
Information on the application note for battery on page 7.
Soldering tip change
Caution, risk of burning!
Tools are not required to change the soldering tip.
Only change a cold soldering tip.
The soldering tip is inserted in handle (15) and can be
removed by simply pulling the soft grip on the soldering tip
(16).
Important
- Change the soldering tip when cold.
- Always ensure that the soldering tip is seated
properly.
