Hi! I've been doing a lot of digging online to find a variable current and voltage power supply that can go from 0-240v and 0-400a with a maximum of 5kw, but cant seem to find anything like that anywhere. Obviously I wont be able to get exactly those specs because of losses due to efficiency, but I would like to get as close to to those specs as I can. Basically, I would like this power supply to be an all purpose one so I can have a way to adjust to any voltage and current rating I want within the limits of 4800w (which is the amount of power supplied by a 240v 20a line). Pretty much if you were to combine an inverter mig welder with an inverter stick welder, you would get the kind of power supply I'm looking for. I would greatly appreciate the help!
