FineLine 170HD Plasma System
WARNING

1.9 Explosion Prevention

The System uses compressed
gases. Use proper techniques
when handling compressed
gas cylinders and other
compressed gas equipment. Observe the
following guidelines to protect against
explosion:
• Never operate the System in the presence
of explosive gases or other explosive
materials.
• Never cut pressurized cylinders or any
closed container.
• When using a water table and cutting
aluminum under water or with water
touching the underside of the aluminum
plate, hydrogen gas is produced. This
hydrogen gas may collect under the plate
and explode during the cutting process.
Make sure the water table is properly
aerated to help prevent the accumulation
of hydrogen gas.
• Handle all gas cylinders in accordance
with safety standards published by the
U.S. Compressed Gas Association
(CGA), American Welding Society (AWS),
Canadian Standards Association (CSA),
or other local or national codes.
• Compressed gas cylinders should be
maintained properly. Never attempt to use
a cylinder that is leaking, cracked, or has
other signs of physical damage.
• All gas cylinders should be secured to a
wall or rack to prevent accidental knock
over.
• If a compressed gas cylinder is not being
used, replace the protective valve cover.
• Never attempt to repair compressed gas
cylinders.
• Keep compressed gas cylinders away
from intense heat, sparks, or flames.

• Clear the compressed gas cylinder
connection point by opening the valve
momentarily prior to installing a regulator.
• Never lubricate compressed gas cylinder
valves or pressure regulators with any
type of oil or grease.
• Never use a compressed gas cylinder or
pressure regulator for any purpose other
than which it is intended.
• Never use a pressure regulator for any
gas other than which it is intended.
• Never use a pressure regulator that is
leaking or has other signs of physical
damage.
• Never use oxygen hoses and pressure
regulators for any gas other than oxygen.
• Never use any gas hose that is leaking or
has other signs of physical damage.
