LIGHT AND RADIANT ENERGY-
When it is necessary to look directly at the arc for diagnostic purposes, do so briefly. Use shade
#10 welding glass (for up to 200 amps) or shade #12 (for 200 amps). During operation, use a shade
not less than #8.
NOTE: During plasma arc cutting, clothing worn should conform to the instructions presented in
the General Safety Requirements section of this manual.
Ultraviolet rays and other radiant energy reflected off the workpiece can produce sunburn.
Therefore, when plasma arc cutting is being performed, anyone working within 25 feet (7.5M) of
the arc should wear an approved, protective full-face mask, a long-sleeved shirt, gloves, and long
pants.
Operations, such as edge cutting, that can cause the arc to be exposed to view should be
avoided, because they can increase exposure to radiant energy.
