NOTES, CAUTIONS AND WARNINGS
OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN BE
DANGEROUS AND HAZARDOUS 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 professional and the manufacturer of the health equipment to determine whether a haz-
ard exists. To prevent possible injury, read, understand and follow all warnings, safety precautions and
instructions before using the equipment. Call your local distributor if you have any questions.
ELECTRIC SHOCK CAN KILL! The plasma arc process uses and produces high voltage electrical
energy. 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 your-
self from the work piece or other parts of the welding circuit. Repair or replace all worn or damaged
parts. Extra care must be taken when the workplace is moist or damp. Install and maintain equipment
according to NEC code. Disconnect power source before performing any service or repairs.
