1. The CNC cutting machine equipment must be reliably grounded, and all electrical components such as the machine tool body, control box and CNC cutting machine plasma power supply must be reliably grounded;
2. Keep your body and clothes dry;
3. Do not stand, sit or lie on wet surfaces when using the device;
4. Provide corresponding insulating materials to prevent electric shock. If you have to work near damp areas, be especially careful, wear insulating gloves, and wear insulating shoes;
5. Provide an air switch with corresponding insurance installed on the wall to connect to the equipment, this switch allows the operator to quickly turn off the power in an emergency;
6. Follow the local electrical regulations to draw up the size and type of the cable;
7. Always check whether the outer layer of the power cord is damaged (bare wire is dangerous), do not use the equipment when the power cord is damaged, if the power cord is damaged, replace it immediately;
8. Frequently check the control CNC cutting machine cable, if it is damaged, it should be replaced or treated before using the equipment;
9. Check the torch wire, if it is damaged or frayed, it should be replaced immediately;
10. If the cover of the plasma power supply device is not installed, do not use the plasma system. The exposed power terminals are very dangerous;
11. Do not pick up the workpiece and waste when cutting the material;
12. Before replacing any electrical components, disconnect the power supply and wait at least 2 minutes, and then switch on the power after the replacement;
13. Do not bypass or short-circuit the power safety device;
14. Before opening the cover of the plasma power supply for maintenance, disconnect the main power supply and wait 5 minutes for the capacitor to discharge before proceeding.https://www.wxsilvercoast.com/
