Buy a transformer for the electric welding machine, and turn the household electricity from 220 V to two-phase 380 v. how to calculate the power of the electric welding machine? Rated output current 300A, rated input voltage 380 / 220, rated frequency 50Hz, rated input capacity 21.6KVA, no-load voltage 60V, rated load duration rate 20%, rated load voltage 32, current regulation range 90-300, can you make a transformer only for welding machine? I don't know very much. What kind of transformer do you want to make? What are the specific parameters?

Yes, but the cost is expensive. It is equal to adding a transformer with the same power as the welder (power ≥ 22kva)
