The soldering unit recommended for this application is the WRS-1 Resistance Soldering Unit which features a continuously variable power control, tweezer-type electrodes, and a foot-actuated energizing switch. The silver solder powder is in a flux suspension, and the melting temperature is approximately +1240 deg F (+670 deg C).

The figure above shows a WK-Series strain gage installation, properly bonded and cured, in preparation for attachment of leadwires by the silver soldering technique.
