For sale is a Complete Diode Rectifier bridge from a 1,000 amp Hobart welder. The silicon elements seem to be plain diodes and NOT silicon controlled rectifiers. The welder was rated for 1,000 amps 100% duty cycle. The welder was obsolete and I scrapped it for copper transformers. This is the rectifier for it. It is a complete package, properly insulated, mount it wherever you want as long as you have proper ventilation. Diodes are marked: W-10933-3-7750 W-10933-3-7801
