I’ve been working with industrial CNC plasma cutters since for a ridiculously long time (circa 1993). Sure, you can easily generate temperatures in the range of 50,000 Kelvin but be aware the process is a total EMI nightmare and it only works on conductive materials. To get a predictable result you also need an adaptive height control that continuously senses the arc voltage and adjusts the Z axis accordingly.

If you do decide to go down that road please be extremely careful because even hundred or so mA of DC current is lethal.
