A transformer (12) and power supply (10) for powering one or more welding stations (24). A spacing layered (12E) is inserted between the primary windings (12A, 12B, 12C) and the secondary windings (12F, 12G, 12H) so as to control the degree of coupling between these windings. In addition, impedances (11, 14, 17) may be used individually or collectively, alone or with the transformer (12), to achieve a desired output voltage-output current characteristic for the power supply (10). The output voltage at the connections (20, 21) of the power supply (10) drops off at a rate selected to minimize heating in the welding stations (24) while maintaining the quality of the weld being performed.
