rupture and explode if damaged�
• Handle and use compressed gas cylinders in accordance
with local or national codes�
• Never allow electrical contact between the plasma arc
and a cylinder�
• Never expose cylinders to excessive heat, sparks, slag or
flames�

Induction heating of certain materials, adhesives, and fluxes
may cause fumes or smoke�
Breathing the fumes and smoke can be hazardous to your
health�
• Keep your face out of the smoke, do not breathe the
fumes�
• Use local exhaust ventilation for fume removal�
• If ventilation is poor, wear an approved air-supplied
respirator�
SMOKE AND GASES CAN
BE HAZARDOUS
• Work in a confined space only if it is well ventilated,
or while wearing an air-supplied respirator� The
smoke and gases from the cutting/gouging process
can displace air and lower the oxygen level causing
injury or death�
• Monitor the breathable air quality as required�
MAGNETIC FIELD CAN
AFFECT PACEMAKERS
• People with pacemakers/hearing aids should avoid
close contact with plasma arc power supply�
• People with pacemakers/hearing aids should consult
their doctor before operating plasma arc power
supply�
Do not exceed the recommended duty
cycle, this can lead to overheating
and cause damage to the system�
• Allow a suitable cooling off period with high demand
usage�
• Observe the duty cycle rating shown on the label
attached to the system�
PLASMA CUTTING CAN
CAUSE INTERFERENCE
• Electromagnetic energy can interfere with sensitive
electronic equipment such as computers, or
computer-driven equipment�
• Ensure that all equipment in the cutting area is
electromagnetically compatible�
• Ensure that the plasma arc cutting system is installed
and positioned in accordance with this manual�
