Making mobile Plasma Cutting Track

When making this device, you tried to use inexpensive parts and relatively simple tools.
The whole thing is powered by an 18v battery and a motor with a gear from an old broken drill.
The cutter used in the video has 45 amps. Theoretically, it can cut up to 10 mm (not qualitative). Using a tracker, I can qualitatively cut about 12 mm.
