1 Soldering[edit | edit source]
The connections of the linear motors in the hot junction boxes are soldered with a special silver solder. Because if you tight the screw of the ceramic clamp, the nickel layer of the copper wire will be destroyed. The nickel layer is very important because it protects the copper of corrosion. At high temperatures the copper wire corrodes until it is completely gone. To avoid this, the connections are soldered which provides a silver layer which protects the copper of corrosion.
You need a resistance soldering pliers, the silver solder and a flux material. These components are delivered with every LISIM line. At first the wires need to be connected in the ceramic clamp. Before you start soldering a function test is mandatory. Then you have to apply the flux material, heat up the clamp and then apply the silver solder. Take care not to heat up the clamp for a long time, because then you will destroy the coat of the wire and the insulation of the high temperature cable. The soldering is successful when the whole wire and the inside part of the clamp is covered with silver solder and there are no heat damages on the wire coat and cable insulation. If there are small heat damages, just make sure that a short circuit is not possible.
