2. General safety instructions
2.1. Normal use
• The scan head is delivered as an OEM component for integration into a laser unit
that is used in a dry and clean indoor environment without electrically conductive
contamination.
• Customers must know and apply the rules and regulations for safe operation of lasers
when installing and operating the scan head and the laser unit in which it is used.
Since Novanta has no influence over the employed laser device or the overall laser
unit, the customer is solely responsible for the laser safety of the entire laser unit.
The laser unit manufacturer bears responsibility for complying with the standards and
guidelines required for the CE (European Conformity) label. Please contact Novanta
for further information about this scan head and applicable guidelines.
• Before installing and operating the scan head, carefully read this manual for your
protection.
• Retain this manual for future reference.
2.2. Reasonably foreseeable misuse
It is considered a misuse if you use the scan head without incorporating it into a laser unit
that complies with the standards required for the CE (European Conformity) label.

5 FIBER_TIGER_manual, 2021-11-29
IMPORTANT
Customers assume full responsibility for maintaining a laser-safe working environ-
ment.
Original Equipment Manufacturer (OEM) customers assume full responsibility
for CDRH (Center for Devices and Radiological Health) certification.
WARNING
Visible or invisible laser radiation
can cause severe retinal and corneal burns, burns on the skin, and may pose a fire
risk.
• To avoid injury and reduce risk of fire, follow the control measures and safety
guidelines provided by the laser’s manufacturer, and those established by your
Laser Safety Officer (LSO), Radiation Safety Officer (RSO), or safety depart-
ment of your business or institution.

2.4. Hazards
2.4.1. Laser radiation
The scan head is intended for use in combination with a class 4 laser.
2.4.2. Laser generated air contaminants
During laser material processing matter is being evaporated. Laser generated air contami-
nants can compose of multitude hazardous products, such as nickel, chrome, alumina, zinc,
butanol, toluol, xylene, and formaldehyde. The concentration, size, and the quantity of
these aerosols and particles are variable in a wide range.

6 FIBER_TIGER_manual, 2021-11-29
WARNING
Laser generated air contaminants, even if respired in lowest concentrations over long
time or brought to skin contact,
can cause skin irritations, contact eczema, sickness, vomiting, cauterization of the
respiratory tract, nervous diseases, allergic reactions, spasms, and cancer.
• To avoid injury, follow the control measures and safety guidelines provided by
the respective material safety datasheet, and those established by your Laser
Safety Officer (LSO), Radiation Safety Officer (RSO), or safety department
of your business or institution.
CAUTION
Hot laser-processed material
can cause skin burns.
• If you are a system integrator, then place a sign at the laser processing area
that warns about hot surfaces.
• When handling material by hand that was laser-processed shortly before then
wear heat resistant protective gloves.
2.4. Hazards
2. General safety instructions
2.4.3. Hot laser-processed material
During materials processing with lasers, strong heating of the processed material may
arise.
2.4.4. Coolant and coolant additives
Some controllers have a cooling loop and use perhaps a special coolant or coolant additives,
like calcination inhibitors, algae inhibitors, anti-corrosion, and anti-freeze agents.

7 FIBER_TIGER_manual, 2021-11-29
CAUTION
Coolant or coolant additives
may give rise, amongst other things, to allergies, eczema, and other irritations if
they get in contact with the skin or mucous membranes.
• To avoid injury, follow the control measures and safety guidelines provided by
the respective material safety datasheet, and those established by your Laser
Safety Officer (LSO), Radiation Safety Officer (RSO), or safety department
of your business or institution.
NOTICE
Electrostatic discharge (ESD)
can damage the controller which is an electrostatic discharge-sensitive device.
• Transport equipment only in anti-static packaging and a packaging equivalent
to that received with the shipment.
• Keep the controller sealed until you are at a proper static control station.
2.
General safety instructions 2.4. Hazards
2.4.5. Electrostatic discharge
The controller contains parts that are sensitive to electrostatic discharge.
A proper static control station should include:
• A soft grounded conductive tabletop or grounded conductive mat on the tabletop
• A grounded wrist strap with the appropriate (1 M Ω ) series resistor connected to the
tabletop mat and ground
• An adequate earth ground connection, such as an uncoated water pipe or AC ground
• Conductive bags, trays, totes, racks, or other storage
• Properly grounded power tools
• Personnel handling ESD items must wear ESD protective garments and ground straps

2.5. Modifications and spare parts 2. General safety instructions
2.5. Modifications and spare parts
You are not allowed to modify the scan head.
You are not allowed to use spare parts other than specified by Novanta.
2.6. Fire extinguishing media
• Use carbon dioxide (CO
2
) as the fire extinguishing media for the scan head.
• The scan head uses internally a direct-current voltage of 48 V. Pay attention to the
minimum distance between the fire extinguishing media aperture and live parts.
• Harmonize the fire extinguishing media of scan head and laser unit.
• Prior to installing the scan head, provide fire extinguishing equipment and observe
its instructions for use and its hazard notes.

3. Overview
A scan head is a device for laser beam shaping and laser beam guidance.
The FIBER TIGER Scan Head is an extremely compact and robust scan head for robot-
assisted laser processing and other “on-the-fly” type applications in the mid to high kW
range.
The scan head can be operated with all commercially available single- or multi-mode fiber
lasers. It is driven by an ARGES system controller and the InScript software or rather by
your own software and the ControllerLib application programming interface.
The scan head features a highly dynamical Z-axis for ultrafast and precise 3D laser material
processing. It has been designed especially for precise welding and cutting applications and
can be employed in a wide range of industrial sectors, for example automotive, aerospace
and machine construction. The FIBER TIGER Scan Head is suitable for industrial-scale
processing of all commonly used materials, such as metals, plastics and ceramics.

Target audience and qualification
Experts
Have ready
Utility knife
Procedure
1. If any shock indicator is present and triggered, then block the delivery and inform the
sender.
2. While carefully unpacking the scan head, keep in mind that you want to retain the
packaging for future use.
In case it will become necessary to return the scan head for some reason later, we
recommend documenting the unpacking e.g. by taking photographs.
3. Check by the delivery note, whether all parts are present, in an evidently immaculate
mechanical state and whether the serial numbers correspond. If one of these is untrue,
then block the delivery and inform the sender.
4. Retain the original packaging for future use.
