Can we use 3ph,220v,50/60hz welding invertor & Transformer in 3ph,440v,50hz and how?can any body explain pl.?

Answer 1

From the details you have supplied:

"3ph,220v,50/60hz welding invertor & Transformer"

Forms the load, and:

"3ph,440v,50hz "

Forms the supply, you cannot use this load on this supply as the voltage of the supply is too high.

You would need a 3 phase transformer to reduce the supply to match the load ie a 2 to 1 step DOWN transformer.
