welding transformer into a step up transformer rather than a stepdown
i know ther has to be but maybe there isnt or if there isnt is there
anyone that knows were i could get a 300 volth 20 amp to 50 amp fixed

No. At least I think not. The welder transformers I've seen are
"ferro-resonant," which means they're regulated, and short- and
overload-resistant. Hooking one up backwards is probably not a
very good idea at all.

Check with surplus dealers, or the power company, for a used pole pig.

What do you need this for? Building an electric smelting furnace?

Good Luck!

Well, you might try rewinding a welder of suitable power (6Kw) so that
the output winding has some 10 times the number of turns.
