Overloading of Transformer

What did the manufacturer say when you asked them, as a result of the advice given to you when you previously posted this question?

Most likely, an arc furnace transformer is designed to limit the current in a short circuit situation. Or are you planning to overload the voltage?

Are you fishing for free professional advice on the basis of more unknowns than knowns? Hire a consultant.

For how long? A few hours? A couple days? Until the transformer explodes?

How about a refrigeration system?
