For real welding of cast iron with cast iron electrodes (not brass and nickel), I will take acetylene and oxygen in cylinders. Everything is adult.you can buy oxygen generators you know?
saw some videos on YouTube years back where people use them for brazing
think most people had an oxygen generators (or a few) feeding into a small compressor - oxygen was only generated slowly and at low pressure, so the compressor stored it for them (just used a normal air compressor)
Used large diameter cast iron compression rings work well.
