Gas cylinders contain gas under high pressure. If
damaged, a cylinder can explode.
• Handle and use compressed gas cylinders in accor-

dance with applicable national or local codes.

Never use a cylinder that is not upright and secured

in place.

• Keep the protective cap in place over valve except

when the cylinder is in use or connected for use.

• Never allow electrical contact between the plasma

arc and a cylinder.

• Never expose cylinders to excessive heat, sparks,

slag or open flame.

• Never use a hammer, wrench or other tool to open a

stuck cylinder valve.

COMPRESSED GAS EQUIPMENT SAFETY

• Never lubricate cylinder valves or regulators with oil

or grease.

• Use only correct gas cylinders, regulators, hoses and

fittings designed for the specific application.

• Maintain all compressed gas equipment and associ-

ated parts in good condition.

• Label and color-code all gas hoses to identify the

type of gas in each hose. Consult applicable national
or local codes.

GAS CYLINDERS CAN EXPLODE
IF DAMAGED

Prolonged exposure to noise from cutting or gouging
can damage hearing.
• Use approved ear protection when using plasma

system.

• Warn others nearby about the noise hazard.

NOISE CAN DAMAGE HEARING

Pacemaker and hearing aid operation can be affected
by magnetic fields from high currents.
Pacemaker and hearing aid wearers should consult a
doctor before going near any plasma arc cutting and
gouging operations.

To reduce magnetic field hazards:
• Keep both the work cable and the torch lead to one

side, away from your body.

• Route the torch leads as close as possible to the

work cable.

• Do not wrap or drape the torch lead or work cable

around your body.

• Keep as far away from the power supply as possible.
