It is possible to solder standard and special low temperature alloys and lead-free alloys

The temperature range for soldering is from 100°C to 350°C

There are only a few applications shown on this site. Click on the images for getting more information about the specific applications.

Soldering of Coils

Simultaneous soldering of the two coil wire ends to terminals using a Spirflame® generator and a LA/2001-Flame Delivery-/Solder Wire Feeder system.

The coil wire ends do terminate on terminal posts as shown above. Then the connector terminals are inserted in corresponding slots in the bobbin body.

Crimp Connections

Crimp connections used in automotive harnesses are "filled" with leadfree solder alloy to prevent humidity and salts entering capillaries and causing long-term corrosion and safety issues on important wire connections.  Used/requested by all/most car/truck makers.

Lead-free solder sealing not only eliminates corrosion issues but at the same time also increases wire pull strength by up to 300%. Tolerance window greatly reduced compared to the crimp-only connection.

The Spirflame® heating combined with the exact solder wire dosing (length and speed) allows automated operation down the tiniest connector assemblies.

Massive crimp terminals also undergo lead-free solder sealing. Contactless, uniform heat transfer makes this possible on automated lines.

High-speed wire harness crimper takes full advantage of the quick and undisturbed heat transfer from the Spirflame® into the material.
