Is there a schematic so I could try and imitate/build one? . Re: 225amp welder dc conversion-capacitor wiring/improvements If you start out with 80 volts AC and run it through a bridge rectifier to charge a capacitor. My father had A very old (late 1960's) Sears AC welder that I learned to weld on ( he was A shipyard welder in WW2 in California) when I took welding during my vo-tech training I realized that an AC/DC machine would be much better than the Sears box but as I was poor as A church mouse in my early 20's I couldn't find one I could afford. First I built this DC arc conversion. If you can get one for $20 it would probably even end up being cheaper.
