Good news. I found a complete, original control for this exact robot on ebay for ~$250! A little wiring and now I am down to debugging coms instead of building a control from scratch. If this project works as i hope, the help everyone shared will be handy when I replicate this setup in a lower

What I did not mention and took for granted that everybody knows is that you nee a THC with the floating head. The THC does the work to keep the torch at the correct cutting and piercing height. There are various systems but most of them look at the arc voltage to determine how high the torch
