I'm trying to build an inverter welder and I need to know how big of an aluminum electrolytic capacitor do I need in order to get 400 amps of output, with 110v input coming from my wall outlet? Can I add several of the 400 amp capacitors in series without increasing the power? Would I need a 4 bridge rectifier on the input to convert to DC? If so how large?
