1.02 IMPORTANT SAFETY PRECAUTIONS
!
WARNING
OPERATION AND MAINTENANCE OF PLASMA ARC
EQUIPMENT CAN BE DANGEROUS AND HAZARD-
OUS 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 hazard exists.
To prevent possible injury, read, understand and
follow all warnings, safety precautions and instruc-
tions before using the equipment. Call your local
distributor if you have any questions.
