Soldering by Joule effect

Introduction :

The resistance-soldering unit is a tool that supplements the usual soldering iron. Its advantage is that it supplies instantaneous localised heat to the work. This is accomplished by passing a highcurrent at low voltage through a resistance contact at the point of application. The current is in the range of 30 - 40 A and between 1 and 4.5 volts.The electrodes applied to the workpiece create the resistance point.

Principle :

The soldering operation consists of clamping the parts to be assembled and adding a solder alloy. The heating process starts as soon as the foot pedal is activated and the temperature rises to the set temperature point (maximum 1100°C}

Benefits :

Improved heat distribution, no risk of component overheating, speed of execution and mechanical holding unaltered.

Application :

connectors on semi-rigid bases, central contacts on coaxial connectors...
