    1 SAFETY Important Safety Precautions OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN BE DANGEROUS TO YOUR HEALTH. Plasma arc cutting produces intense electric and magnetic emissions that may interfere with the  proper function of cardiac pacemakers, hearing aids, or other electronic health equipment. Persons who work near plasma arc cutting applications should consult their medical health provider, authorised technician and the manufacturer of the health equipment to determine whether a hazard exists.
  • Page 5 This electric energy can cause severe or fatal shock to the operator or others in the workplace. Never touch any parts that are electrically “live” or “hot.”  Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the cutting ...
  • Page 6 Wear cutting gloves and suitable clothing to protect your skin from the arc rays and sparks.  Keep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or dirty.  Protect others in the work area from the arc rays. Use protective booths, screens or shields. ...

    2 Technology Parameters 2.1 Working principle of main circuit The working principle of ArcoCut 100i Air Plasma Cutting Machine is shown as the following figure. Three-phase 380V work frequency AC is rectified into DC (about 530V), then it is converted to medium frequency AC (about 40 KHz) by inverter device (discrete IGBT), after reducing voltage by medium transformer (the main transformer) and rectified by medium frequency rectifier (fast recovery diode), and is outputted by inductance filtering.
