CA 1268219

ABSTRACT The invention is directed to an AC power supply for portable welding machines or the like which employ a transformer of either single or multi-phase power wound around a cylindrical core. The core is constructed from a continuous length of steel alloy ribbon. The individual windings of both the primary and secondary are spaced apart. In operation the transformer is submerged in a heat transfer medium to provide cooling thereof by heat transfer therefrom. The transformer may have either a tapped primary or secondary or both to provide secondary amperage for the intended use of the transformer. An external cooling radiator may be employed to provide additional cooling to the heat transfer medium.
