I'm looking for a method to clean up the inlet voltage for a welder. I guess you'd call it something like a surge protector. The power source varries from 580V to 680V depending on what is going on in other areas of the rig. That is outside of the 10% allowed by the circuit protectors. Somebody mentioned a capacitor bank... Does anyone know of a company that specializes in cleaning up power?
Thanks!!!!!!!!
