Consult 1 sets of 100KVA butt welding machines. What is the power? How much is the power consumption per hour?
Should it have something that regulates the current?. P=u*i if the voltage is 380, the regulating current is 300A, then the power is U=300*380=114KW
The most conservative approach: welding work, clamp the power supply current: A*V is power (W), if it is three-phase welding machine, then *1.4.
A*V is the power (W), if it is three-phase welder, and then *1.4.
