The plasma system uses compressed gas. Proper precautions must be
observed when handling and using compressed gas equipment and cylin-
ders. Refer to the Standards Index in this manual.
When cutting with the plasma system:

• Do not cut pressurized cylinders or any closed container.
• Maintain all pressure regulators in proper working condition. Faulty regulators can
cause damage or operator injury and must be serviced by trained repair techni-
cians.
• Never use a regulator for any gas other than that for which it is intended.
• Never use a regulator that leaks, creeps excessively or is physically damaged in
any way.
• Never attempt to lubricate a regulator with oil or grease.
• Handle and use compressed gas cylinders in accordance with safety standards
published by the Compressed Gas Association (CGA ), American Welding Society
(AWS) and Canadian Standards Association (CSA).
• Never use a cylinder that leaks or is physically damaged.
• Never use a cylinder that is not upright and secured in place.
• Never move or transport a cylinder without the protective valve cover in place.
• Never use a gas cylinder or its contents for any purpose other than that for which
