A CNC cutter is a thermal cutting tool that uses a plasma torch to cut various metals producing clean and accurate cuts. “I use it to make computer-generated metal signs,” said Reed.

The CNC machine uses a handheld plasma cutting torch as its base, which uses a blowback start mechanism making it usable in an automated CNC setup without interfering with the control electronics.
