The Italian industrial motor is sealed for best protection from the elements and stainless pump and bronze impellor are designed for long life. The direct drive reduces maintenance and repair. The standard unit is 240V. This unit is designed to stack under the PowerTIG 315LX, 350EXT, Lightning MTS 275, PowerMTS 400 and Power i-MIG 353DPi. Notice: Everlast is aware that customers may be using various types of coolant in their PowerCool Water Coolers and with our NOVA or other brand TIG torches. These range from distilled water to Isopropyl alcohol to automotive type anti-freeze to R.V. anti-freeze to “private concoctions.” Since the PowerCool product line was released over 12 years ago we’ve gathered valuable data and gained experience concerning the use of coolants and their impact on both the lifespan of the cooler and the TIG torches themselves. With that said, there are several areas of concern that we look for in a coolant. We have found that most popular alternatives fail to provide satisfactory performance. We have taken our findings and concerns and listed them below as basic elementary requirements needed for best performance and product life.
