PLASMA ARC RAYS
Plasma Arc Rays can injure your eyes and burn your skin. The plasma arc process produces very bright
ultraviolet and infrared light. These arc rays will damage your eyes and burn your skin if you are not
properly protected.
• To protect your eyes, always wear a welding helmet or shield. Also, always wear safety glasses with
side shields, goggles or other protective eye wear.
• Wear welding gloves and suitable clothing to protect your skin from the arc rays and sparks.
• Keep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or dirty.
• Protect others in the work area from the arc rays. Use protective booths, screens or shields.
• Use the shade of lens as suggested in the following per ANSI/ASC Z49.1:

HEAVY COMPONENTS
CNC Saddle Machines in their storage cases and certain components of the Mathey Dearman CNC Saddle
Machine are heavy. Use caution when lifting or moving these items. Use team lifting when necessary to
avoid personal injury. When using a mechanical device to move a machine follow all manufacturers’
safety guidelines. Pipe being operated on with the machine may be heavy. Use all lifting guidelines
outlined in Occupational Safety & Health Administration technical manual Sect. 7, Ch. 1.5. See
publications section for additional information.
ELECTRIC AND MAGNETIC FIELDS
Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF).
Welding and plasma cutting current creates EMF fields around cables and machines. EMF fields may
interfere with some pacemakers, and operators and observers having a pacemaker should consult their
physician before operation. Exposure to EMF fields may also have other health effects which are now not
known.
