The machine is equipped with a 110V transformer. The host socket is first plugged into the transformer, and then the transformer is connected to the 110V power supply.
This requires refrigerant cooling, using ethylene glycol. Water doesn't work, it freezes when it reaches 0 degrees, and the refrigerant drops from room temperature to minus 20 degrees.
The temperature is related to the coolant, capacity and heat you use. The machine can reach minus 20 degrees Celsius, but there are many factors that affect the temperature.
