Be careful here... Most of these IEC plugs like this in Asia or Europe use 250V, 50Hz supply.
So, if your machine transformer is set up for 250V, 50Hz and you energize at 120V, 60Hz, not sure what the results might be.
Check the nameplate or ratings on things before you turn that baby on.
Just my 2 cents...
You can purchase a universal travel converter that might carry your machine with the normal 120V outlet voltage.
There are many varieties and brands of these available at different prices and shapes, but here is one:

Edit here: this one will not work because it is designed to plug into 250V outlet and energize 120V devices.
Your machine could be a 250V device, so this converter is not appropriate, I don't think.. But you get the idea...
