Resistance Soldering - The components to be soldered are held between two electrodes and form the part of the electrical circuit. A low voltage high Amp., current is passed through this circuit, heating the surfaces to be joined to the temperature at which the preplaced and sand wiched flux and solder begin to melt. Pressure is maintained until the solder has solidified.
Resistance soldering has the advantage of highest joint production, no warm up requirements, and instant controlled heat. Since work is heated only at the points of contact, the danger of melting nearby points or burning other parts is minimized.
