    Yes, the welder needs a circuit capable of handling that load. I doubt the 20 amp circuit can handle the welder.

    What does 90A mean? Is that the output?

    If so tell us what the input amperage is. The output amperage is meaningless as far as wiring it goes.

    Also, how far is the barn? If it is quite far then larger wire will definitely be needed.
