Utah Power would not need to be involved, but you would have to have the electriction take out a permit, which means all his work would have to be signed off by an inspector for the either the State or the City, not sure which one.

Since I don't know the layout of the house you are moving too, there could be a few hold ups. If the house is old, chances are that there might not even be enough power coming into the house(if there is an electric dryer hookup ignore this statement) Also, they would have to fish wires through the walls, and install a new breaker(assuming there is room in the box) All this plus the price of the breaker/outlet combo, I am guessing you are looking at at least $500 just to get the outlet installed.

Electrical and plumbing add up quickly when you consider they charge out on average of $75/hour.

With what I see and hear you wanting to do with this welder, I think you could get by with a 110V. I think it would last you long enough to get the use out of it, plus it doesn't require any special outlet.
