Troubleshooting (cont.)
Danger
serious
personal
injury
Ensure that DC power to the laser is turned off and locked out before inspecting optical
components in the beam path.
Invisible CO
2
laser radiation is emitted through the
lens. Corneal damage or blindness may result from exposure to laser radiation.
Caution
possible
equipment
damage
If you operate your laser or marking head in a dirty or dusty environment, contact
SYNRAD about the risks of doing so and precautions you can take to increase the
longevity of your laser, marking head, and associated optical components.
Warning
serious
personal
injury
The use of aerosol dusters containing difloroethane causes “blooming”, a condition that
significantly expands and scatters the laser beam. This beam expansion can effect mode
quality and/or cause laser energy to extend beyond the confines of optical elements in
the system, possibly damaging acrylic safety shielding. Do not use air dusters containing
difloroethane in any area adjacent to CO
2
laser systems because difloroethane persists
for long time periods over wide areas.
Shut down the laser and carefully inspect each optic in the beam delivery path, including the laser’s output coupler. Remem-
ber that optics are fragile and must be handled carefully. If the optic requires cleaning, then refer to the
Firestar v40 Opera-
tor’s Manual
and use only recommended cleaning materials to prevent scratching delicate optical surfaces.
If the focusing optic is pitted, it must be replaced immediately. Because of the extremely high power density of Firestar lasers,
pits or debris on the lens may absorb enough energy from the focused beam to crack the lens. If this happens, other optics in
the beam path may be contaminated or damaged as well.
When the laser application requires air (instead of nitrogen or argon) as an assist gas, use breathing quality air available in
cylinders from a welding supply company. Compressed shop air contains minute particles of oil and other contaminants that
will damage optical surfaces and must be carefully filtered and dried before use as a purge or assist gas.
A risk of exposure to toxic elements, like zinc selenide, may result when certain optical
or beam delivery components are damaged. In the event of damage to laser, marking
head, or beam delivery optics, contact SYNRAD, Inc. or the optics manufacturer for
handling instructions.
