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
associated 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
COMPRESSED GAS EQUIPMENT SAFETY
Gas cylinders contain gas under high pressure. If
damaged, a cylinder can explode.
• Handle and use compressed gas cylinders in
accordance 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.
Frozen pipes may be damaged or can burst if you
attempt to thaw them with a plasma torch.
NOISE CAN DAMAGE HEARING
A PLASMA ARC CAN
DAMAGE FROZEN PIPES
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.
