- General metalworking (cutting, drilling)
- Welding
- Advanced assembly work (requires specific tools, measurement instruments, and an understanding of tolerances for alignment and assembly)
- General electrical work (wiring safety switch, temperature controllers, etc.)
- Motor electrical work (wiring motor, contactor, overload protection, etc.)
