The Single shaft design means the fan and the pump are direct driven by a sealed industrial motor. The cooler is also equipped with a copper cored radiator for long life and better cooling. The unit is equipped with color coded Quick connect couplings for water lines that are designed to be used with the torches supplied by AHP. This greatly simplifies change over and reduces changeover time if a torch needs to be swapped.Make sure to pair the Water Cooler with an AHP compatible Water Cooled TIG Torch with a 35-70 DINSE Connection or use similar adapters for aftermarket torches. Use only TIG rated coolant. In addition the coolant should be designated as "low conductivity" or "safe for HF TIG use". Do not use automobile coolant or coolant rated for MIG or Plasma cutting only. AHP currently does not supply coolant, however it is available at most welding supply stores in almost all areas. This cooler is rated for 208-240V use only. It is designed specifically for the new digitally controlled AlphaTIG series. Older models will not accept the cooler plug.
