SI2R Joule soldering set

Joule soldering (also known as resistance soldering) is a tool that complements the usual soldering iron. Its advantage is to provide instant localized heat. The principle is to pass a powerful current at very low voltage through a contact resistance at the point of application. The current is on average 30 to 40 A and between 1 to 4.5 V. The electrodes applied to the piece create the point of resistance.

Principle :
The soldering operation consists in pinching the parts to be assembled and providing an alloy of tin. As soon as the pedal is engaged, the temperature rises instantly to the desired temperature (max. 1100 ° C).

Benefits / Quality :
Better distribution of the heat (=better distribution of the solder), no overheating of the component (=instantaneous welding 1100 ° C), speed of execution, mechanical maintenance of the part.

Application :
Connector soldering on semi-rigid, coaxial connector soldering, soldering of several strands at the same time etc.
