IPG Photonics Corporation
IPG delivers fiber lasers in all domains of laser material processing, medical engineering and
scientific institutes and universities. IPG is the accepted market leader in this modern fiber
laser technology. The IPG Photonics Corporation contains subsidiaries in many European,
Asiatic and American developed counties. Main production site for these lasers is Burbach in
Germany with a vertical range of manufacture of 90%. This guarantees you as user a high
grade of competence and reliability.
High output power, excellent beam quality, high stability and mobility are outstanding
predicates of the fiber laser. The superiority of the fiber laser is efficiency, flexibility,
modularity, thermal and mechanical robustness that comes along with a simple constructive
assembly. Further important characteristics for the industrial use are low running costs.
Economic feasibility studies show, that it is possible to realize faster, better and more cost-
effective industrial applications with high power fiber laser. IPG has the production capacity
for a production in high piece numbers. More information you can find under

In order to ensure the safe operation and optimal performance of the product, please follow
these warning and caution notes in addition to other information contained elsewhere in this
document.
WARNING:
Make sure the instrument is properly grounded through a protective
conductor of the AC power cable. Any interruption of the protective ground
conductor from the earth terminal can result in personal injury.
CAU
TION
:
Before supplying the power to the instrument make sure that a correct
mains voltage of the AC power source is used. Failure to use the correct
voltage could cause damage to the instrument.
WARNING:
No operator serviceable parts inside. Refer al
l servicing to qualified IPG
personnel. To prevent electrical shock, do not remove covers. Any
tampering with the product will void the warranty.
WARNING:
For
continued protection against fire hazard, replace the line fuses only
with the same types and ratings. The use of other fuses or materials is
prohibited.
WARNING:
If this instrument is used in a manner not specified in this document, the
protection provided by the instrument may be impaired. This product must
be used only in normal conditions.
CAUTION
:

Laser Classification
This device is classified as a high power Class IV laser instrument under 21 CFR 1040.10 [and
under IEC 60825]. This product emits wavelength light at or around 1070 nm at total power of
light radiated out of the optical output greater than 200 Watts. This level of light may cause
damage to the eye and skin. Despite the radiation being invisible, the beam may cause
irreversible damage to the cornea. Laser safety eyewear is not provided with this instrument,
but must be worn at all times while the laser is operational. Use the right laser safety
goggles.
WARNING: Do never install output connector or collimator when laser electrical
power is ON.
WARNING: NEVER look directly into the laser optical output when laser is ON and
make sure that you wear appropriate laser safety glasses at all times
while operating the product.
CAUTION: Use of controls or adjustments or performance of procedures other
than those set forth in this guide may result in hazardous radiation
exposure.
