For sale is a nice assembly consisting of a Carbonator motor, pump, and Radiator. A fan is wired with motor and cools the radiator. All 110v. I made it and used it for 2 years for TIG welding. It never gave me any problems and always worked great. I started to make some money and replaced this one with a Miller Coolmate 3. But you may have the same, or similar, use for this one.
