Anyone have anything on the lines of stepping down the voltage for a small 110v welding machine and adding a hard tip to use as a Auto pounce?

A pounce machine takes quite abit higher voltage than is available on a welding machine. The welding machine has a secondary voltage of around 80 volts and the electro pounce is a few thousand volts. I built one from an old furnace ignition transformer. It works great, just put a foot switch in the 110 volt side and only step on the switch when the tracing stylus is in contact with the work. If you pull the stylus up without releasing the foot switch, it will arc and flame the pattern paper. A friend of mine named mine "Ole Sparky" because everytime he tried to use it he got bit.

The previous reply is SO accurate, at least in regards to the arcs and flames part. We used to make them from used neon transformers. problem was, sometimes we couldn't get a small one, and it was flame city! That's why the foot cutoff switch is such a good Idea.A reostat (like a dimmer switch) would be nice, (that's probably the biggest difference between an Electro-pounce Jr. and Sr.) I just don't know where you'd put the reostat. My electro-pouce Sr. is real handy, this is worth pursuing. Jim.

I've tried both, making my own and owning an electro-pounce . Given the variables and danger of electric shock,it is much easier just to go out and buy an electro-pounce.I have made several over the years and unless it is a necessity the time you spend trying to get all the parts together and then assembly could buy one of them.
