Safety
SR-45i User’s Manual
•
Never operate the SR-45i system without all of the covers in place.
•
Preventive maintenance should be performed daily to avoid possible safety
hazards.
Fire Prevention
When using the SR-45i system, it is necessary to exercise good judgment. While
cutting, the arc produces sparks that could cause a fire should they fall on
flammable material. Make sure that all flammable material, such as paper, cloth,
etc., is a suitable distance away from the cutting area. All flammable liquids
should be at least 40 feet away from the cutting area, preferably stored in a metal
cabinet. Plasma cutting should never be attempted on containers that contain
flammable materials. Make sure that fire extinguishers are readily accessible in
the cutting area.
Explosion Prevention
The SR-45i 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 SR-45i 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
1-3
