This 240V PowerCool cooler can be used with any Everlast welder new or old with the triangular shaped power outlet in the rear. This includes the new generation units from Dec 2020. Note: 2009 and some 2010 model use a different outlet shape, but still provide 240V to the rear of the unit. When using with the new and old generations, the PowerCart 250 should be used with the TIG and cooler package. The cooler is sized to fit on the bottom shelf. (See picture above for combination). Extended lines are included as well to mount the cooler in alternate locations apart from the welder. It can be easily picked up and carried. This is a non stackable design and works well for general pupose cooling tasks. The Power Cool W300 240V water cooler from Everlast is designed to work with Everlast TIG welders to provide the maximum cooling capacity and includes a special 240V plug for the socket on the Everlast welder rear panel. This plug may be removed or changed for applications with other brands of welders. The unit features color coded quick connectors for rapid and correct connection of the torch lines. The radiator is made from copper for maximum cooling capability. The Italian made pump is made from stainless steel with a bronze impeller for maximum wearability. The Italian industrial motor is sealed for best protection from the elements. The standard unit is 240V. 120V is available for other units with 120V requirements. A generous reservoir holds just a little over 2 gallons of coolant for maximum circulation capacity. Use only distilled water or antifreeze specifically designed for use with TIG/MIG torch coolers. Do not use automotive anti freeze!
