Abstract

A simple and reliable regulator has been developed for an uncontrollable welding rectifier based on the UMZP-40-80-51 magnetic amplifier. The regulator is designed for smooth remote regulation of the strength of the welding current in automatic welding under flux of parts of carbon and corrosion resistant steels. It provides the capability of obtaining stable and steeply dropping external characteristics of the power source. It is shown that with a change in current in the circuits of the control windings of the magnetic amplifier there is a change in its inductive impedance and, as a result, in the voltage and current strength on the output of the power source. To decrease the pulsations in the rectified current a smoothing choke is connected in series in the welding circuit. The use of the regulators developed provides an approximately 7% increase in welder labor productivity as the result of the reduction in auxiliary time. The saving in power obtained with the introduction of a single regulator into production is 91, 000 KW multiplied by (times) h.
