I'm kind of mystified why a Korean place would be selling appliances meant to run on 220 volts, unless perhaps they were also selling up-converting transformers.
My guess is that this machine wouldn't use a lot of current to operate, so in theory you could use one of those international travel voltage converters in reverse without burning it out..
