Indicator for Weller Soldering Stations
Weller/Cooper Tools Group's ‘Magnastat’ have a good reputation for reliability and the circuit suggested here is an add-on indicator lamp to show when the soldering tip is up to temperature. The circuit is intended to be installed in the housing which forms the base of the soldering iron. An LED fitted to the front panel indicates when the iron is heating.
