I hope so that You realize trafo needs. About 2KW trafo needed if (50Hz), better consider switcher power supply.
Torus in my country is about 160eur and for 2KW is about 11kg of weight.

I supose that You need this for Arc Welding ? :wink:

You cant use direct regulator IC for that they dont have enogh power for that job. They must be used with strong transistors.

I send You some examples even for 40A, here they are:
