electrical - 220 V equipment from asia in USA

I have a machine coming from Vietnam (220 v 50hz) and need to run it in the US. I am aware standard house socket is 110 V 50 hz but I have a welder wired up using a dual breaker to give 220V.

Will the machine run off the welder outlet or is there something about the way its connected that makes the power different ?

Assume the 50 hz vs 60 hz is not an issue.

I have priced a unit that takes 110 input and produces 220 V pure sine output but would like to avoid the cost if possible.

@markr9,

I can't help with that particular situation. It is quite normal for welders to run either on 220 or an internal combustion engine that have outlets for 110. Your situation sounds exactly opposite the normal device.

When you say 'welder outlet' what is that? 110 or 220, and is it single or three phase?

We are not electricians.

Spend $30 and consult a licensed electrician who can come look at the actual situation rather than a textual description of what it might be.

I assume then 9 that your house has two phases

Probably not but make sure ground wire goes to the case

I'd assume your new machine might be a trifle less powerful at the higher line frequency

I presume it's called a "transformer"

About $100 for 5 kva

@dalehileman,

The device suggested is an inverter to supply a clean 220 V at 50 hz. Its about 500 dollars.

I could go with a transformer but those dont seem to address the 50/60 hz issue.

thanks for the replies though.
I am a bit jealous of getting an electrician for $30 , in my area its $120 an hour or part thereof.

Beginning to understand, the device also converts to 50 hz. However still think you should try out your appliance on 60 hz
