COOLING PUMPS FOR HELIARC WELDING, MILLER - HOBART - LINCOLN

Oberdorfer has a long history of supplying pumps to the welding machine industry. Ever since the Heliarc welding technology was developed, Oberdorfer pumps were used to circulate cooling liquid to the welder’s torch. Pump and electric motor are usually mounted on top or on the side of the coolant tank. A pressure relief valve built into the pump returns excess liquid directly to the tank rather than to the suction side of the pump, thus avoiding heat build-up in the pump. Pump models N1000R39 and N1000R-66 are coupled to the electric motor with a flexible coupling. The N95060GEC03 and N95060GFC01 models are close-coupled to a carbonator motor by a circular clamp arrangement, offering a space-saving, compact design alternative. Pump model N95060GE is a retrofit for Miller Electric Mfg. Co.
