ABSTRACT:
An electric welder has magnetic cores with windings thereon which perform the functions of transformer windings as well as the functions of magnetic amplifier windings. The secondary windings, on each pair of those magnetic cores, are connected in series relation; and, similarly, the control windings on that pair of magnetic cores are connected in series relation. One of those control windings can have the voltage across it reduced to essentially-zero to cause a high voltage to be developed across the control winding on the other of that pair of magnetic cores--with consequent prompt saturation of that other magnetic core and with the development of an output pulse by the secondary windings on that pair of magnetic cores.
