An inexpensive semiconductor-controlled regulator for the dc spectrographic arc is described. It is used for maintaining steady arc currents from 1 to 15 A, ±50 mA with a 120-V dc source. It is unique in that it employs solid-state circuitry. As compared to the conventional multipurpose
power source with current regulators, the present model offers advantages of compactness, easier installation, and economy.
