I am working on cruise ship and I both café machine.I am from Europe and we are using 220V and café machine is using only 110V...
I know that I can bay converter but is to heavy for luggage...
Can I somehow rewire that machine so it can use 220V?
Thanks in advance...

Typically no. Then again, some things these days, like computer power supplies, have a switch to run off 120 or 220v. I have not seen any appliances that have this feature though.
It must be run at the voltage spec'd.
So it's either a converter rated for the capacity of the appliance (wattage), or don't use it.
