how use a machine with different voltage
In the 50th the distribution of electricity in Italy was in the hands of some private companies that decided prices and mode of production.
The voltage of domestic appliances were much different, as 110-volt, 125, 150, 160, 220, 230, 260, 280.
The nationalization and the subsequent unification of the voltage to 220 volts took place in 1962. Consequently there are still many coffee machines produced in those years with a different voltage than the standard. Also there are many countries where the present voltage is 110 volts (U.S., Canada, Taiwan, ...)
ESPRESSO MACHINE 110-125 VOLT/220-240-260 VOLT
If the conversion is between 110 volt and 220 and vice versa, it is sufficient to use a transformer. The transformer power must be adequate for the power of heating element. The household espresso machines have usually a capacity ranging from 550W to 1300W, so you need a transformer with an output of at least 3000W, like this
ESPRESSO MACHINE 160 VOLT
If the conversion is between 110 volt and 160 volt is it possible uses the machine without transformer. The heating time will be more slow, about twice.
I have personally tested two machines to 160 volts, a Faemina and a Gaggia Gilda first model.
- GAGGIA GILDA
The Gaggia Gilda reaches the proper temperature in about 10-12 minutes, then must be switched off because has a single heating element. No other tests performed.
Before tests, I installed a pressure gauge on the steam tap. Be noted that the faemina works at a pressure of 0.2 atm
I compared a 160 volt machine (with 110 volt line) with
a 220 volt machine.
Alternatively you can use a Variac, that allows to transform 110 volt or 220 volt to 160 volt.
