Danger from Toxic Gases and Vapors
Please take the following precautions for your own personal safety:
Persons present in the sealed cell for the LaserHybrid process must
wear rigid, wet-insulating footwear
-
protect hands with appropriate gloves (featuring electrical insulation and
-
thermal protection) protect their eyes from laser beams by wearing regulation-compliant safety
-
glasses for lasers. To protect their face and eyes against UV beams, further protection in the form of a protective shield with regulation-compliant filter insert for laser protection class 4 must also be used in front of the safety glasses for lasers and the person's face. Do not look into the laser beam, even with a regulation-compliant filter insert for laser protection class 4. Only wear suitable (flame-resistant) clothing
-
Wear hearing protection designed for crossjet noise (120 dbA)
-
If there are persons present in the sealed cell for the LaserHybrid process,
inform them of all the dangers that may be posed during operation (e.g. po-
-
tential accumulation of gases hazardous to health, risk of asphyxiation due to lack of oxygen in the breathable air, hazards posed by laser light, etc.) provide protective equipment
-
construct protective walls or install protective curtains.
-
The fumes produced during welding contain toxic gases and vapors.
Welding fumes contain substances that may cause birth defects and cancer in some circumstances.
Keep your head out of the welding fumes and gases.
Take the following precautionary measures for fumes and harmful gases:
Do not breathe them in.
-
Extract them from the work area using appropriate equipment.
-
Ensure that there is sufficient fresh air.
Use breathing apparatus with air supply if there is insufficient ventilation.
When no welding is taking place, close the valve of the shielding gas cylinder or the main gas supply.
If there is uncertainty as to whether the extraction capacity is sufficient, com­pare the measured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the welding fumes are:
The metals used for the workpiece
-
Electrodes
-
Coatings
-
Cleaning agents, degreasers, and the like
-
Consult the corresponding material safety data sheets and manufacturer's in­structions for the components listed above.
Keep flammable vapors (such as solvent vapors) out of the laser and arc radi­ation range.
8
Danger Posed by Shielding Gas Leak
Risk of asphyxiation due to uncontrolled shielding gas leak
Shielding gas is colorless and odorless and may suppress the oxygen in the ambi­ent air in the event of leakage.
Ensure there is a sufficient supply of fresh air with a ventilation flow rate of
-
at least 20 m³ per hour. Please observe the safety and maintenance information for the shielding gas
-
cylinder or the main gas supply. When no welding is taking place, close the valve of the shielding gas cylinder
-
or the main gas supply. Always check the shielding gas cylinder or main gas supply for uncontrolled
-
gas leakage before each start-up.
EN-US
Danger from Fly­ing Sparks
Danger from Welding Current
Flying sparks can cause fires and explosions.
Never undertake welding near flammable materials.
Flammable materials must be kept at least 11 meters (35 ft.) from the LaserHy­brid welding process or protected with a certified cover.
Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through small cracks and openings. Take appropriate measures to ensure that there is no risk of injury or fire.
Do not undertake welding in areas at risk of fire and explosion, or on sealed tanks, drums, or pipes if these have not been prepared in accordance with cor­responding national and international standards.
Do not undertake welding on containers in which gases, fuels, mineral oils, and the like are/were stored. Residues pose a risk of explosion.
An electric shock can be fatal. Every electric shock poses a risk of death.
All welding power-leads must be secured, undamaged, and insulated. Replace loose connections and scorched cables immediately.
Stray Welding Currents
EMC Measures WARNING! Electromagnetic field! Electromagnetic fields may cause health
If the following instructions are not observed, stray welding currents may occur, which can result in the destruction of ground conductors, the power source used, the LaserHybrid head, and other electrical equipment.
Ensure that the workpiece terminal is securely connected to the workpiece. If the floor is electrically conductive, set up the power source so that it is insulated wherever possible.
problems that are not yet known.
The operator is responsible for ensuring that there is no electromagnetic inter­ference with electrical and electronic equipment.
If electromagnetic interference is discovered, the operator is obliged to take ac­tion to rectify the situation.
9
Check and evaluate possible problems and the interference immunity of equip­ment in the vicinity according to national and international regulations:
Safety devices
-
Grid power lines, signal lines, and data transfer lines
-
EMC and telecommunications equipment
-
Devices for measuring and calibrating
-
The health of persons close by, e.g., those with pacemakers and hearing aids
-
Persons with pacemakers must seek advice from their doctor before staying in the immediate vicinity of where the welding work is taking place.
Supporting measures to avoid EMC problems:
Grid power supply
a)
If electromagnetic interference occurs despite a grid connection that
-
complies with regulations, take additional measures (e.g., use a suitable grid filter).
Welding power-leads
b)
Keep them as short as possible
-
Route them close together (also to avoid EMC problems)
-
Route them far from other lines
-
Equipotential bonding
c)
Workpiece grounding
d)
If necessary, establish grounding using suitable capacitors
-
Shield, if necessary
e)
Shield other devices in the vicinity
-
Shield the entire welding installation
-
Particular Haz­ard Areas
Laser beam poses a risk of injury to the eyes. In addition to using the protective shield with a regulation-compliant UV filter insert, eyes should be protected from laser beams using regulation-compliant safety glasses for lasers. It must still be ensured, however, that no one can accidentally look into the laser beam.
If the workpiece surface is especially bright or highly reflective, reflected laser- scattering radiation poses a further risk. Take suitable precautions so that per­sons present have adequate protection from laser-scattering radiation also.
Keep hands, hair, loose clothing, and tools away from moving parts, such as:
Ventilators
-
Gear wheels
-
Rollers
-
Shafts
-
Wirespools and welding wires
-
Do not insert body parts into rotating gear wheels on the wire drive or into rotat­ing drive parts.
Covers and side parts must only be opened/removed during maintenance and re­pair work.
During operation:
Ensure that all covers are closed and all side parts have been mounted prop-
-
erly. Keep all covers and side parts closed.
-
10
Welding wire from the welding torch poses a high risk of injury (cuts to the hand, injuries to the face and eyes, etc.).
For this reason, always hold the welding torch away from your body (devices with wirefeeder) and wear suitable protective goggles.
Do not touch workpieces during or after welding – risk of burns.
Slag may fly off from workpieces that are cooling down. For this reason, be sure to wear regulation-compliant protective equipment and ensure that other people are sufficiently protected even when reworking workpieces.
Leave the welding torch and other parts with a high operating temperature to cool before working on them.
Special regulations apply in areas where there is a risk of fire or explosion – observe relevant national and international regulations.
Power sources for work in spaces where electrical hazards pose a greater risk (e.g. the boiler room) must be marked with a (Safety) sign. The power source should not be located in these types of spaces, however.
Risk of scalding due to coolant leakage. Before disconnecting connections for the coolant supply hose or return connection, switch off the cooling unit.
When handling coolants, observe the specifications on the safety data sheet. The coolant safety data sheet is available from your service center or from the manu­facturer's homepage.
Only use suitable load-carrying equipment from the manufacturer for transport­ing devices by crane.
Attach chains or ropes to all designated suspension points on suitable load-
-
carrying equipment. Chains or ropes must be as close to perpendicular as possible.
-
Remove the gas cylinder and wirefeeder (MIG/MAG and TIG devices).
-
EN-US
Informal Safety Measures
Always use a suitable wirefeeder hoisting attachment with insulation on the crane for hoisting the wirefeeder (MIG/MAG and TIG devices).
If the device is fitted with a carrier belt or handle, this should be used exclusively for transportation by hand. The carrier belt is not suitable for transportation by crane, counterbalanced lift truck or other mechanical chain hoists.
All lifting equipment (belts, straps, chains, etc.) used in connection with the device or its components must be checked regularly (e.g., for mechanical dam­age, corrosion, or changes due to other environmental influences). The test interval and scope must, as a minimum, comply with the respective valid national standards and guidelines.
There is a risk of colorless, odorless shielding gas escaping without notice if an adapter is used for the shielding gas connection. Use suitable Teflon tape to seal the thread of the shielding gas connection adapter on the device side before in­stallation.
The Operating Instructions must always be at hand wherever the LaserHybrid head is being used.
In addition to the Operating Instructions, all applicable local rules and regula­tions regarding accident prevention and environmental protection must also be made available and be followed.
All safety and danger notices on the LaserHybrid head must be kept in a legible state.

No. Function
(1) Gas-test button
To set the required quantity of gas on the gas pressure regulat­or
After pressing the gas-test but­ton, gas is released for 30 s. Pressing the button again ends the process early
No. Function
(2) F1 button
No function at present
(3) Wire-return button
For retracting the wire electrode without gas or current
Whilst the button is being pressed, the wirefeeder operates at the preset wire-return speed
There are two options available for retracting the wire electrode:
Option 1
Retract the wire electrode at the preset wire-return speed: Press and hold the wire-return button
After pressing the wire-return button, the wire electrode is retracted
-
by 1 mm (0.039 in.) After a brief pause, the wirefeeder continues retracting the wire elec-
-
trode – if the wire-return button is kept pressed down, then the speed increases with each further second by 10 m/min (393.70 ipm) until the preset wire-return speed is reached
Option 2
Retract the wire electrode in 1 mm steps (0.039 in. steps) – always press the wire-return button for less than 1 second (tap)
IMPORTANT! Only retract the wire electrode a small amount at a time, to avoid the wire electrode becoming entangled on the wirespool during re­traction.
IMPORTANT! If there is a ground earth connection with the contact tip, then before the wire-return button is pressed, the wire electrode is retrac­ted by pressing the wire-return button until the wire electrode is short-cir­cuit-free—however by a maximum of 10 mm (0.39 in.) each time the but-
34
ton is pressed. If the wire electrode is retracted further, press the wire-return button again.
(4) Wire-threading button
For threading the wire electrode into the torch hosepack without gas or current
Whilst the button is being pressed, the wirefeeder operates at the preset feeder inching speed
There are two options available for the wire threading:
Option 1
Thread the wire electrode at the preset feeder inching speed: Press and hold the wire-threading button
After pressing the wire-threading button, the wire electrode will be
-
threaded in by 1 mm (0.039 in.) After a brief pause, the wirefeeder continues threading in the wire
-
electrode – if the wire-threading button is kept pressed down, then the speed increases with each further second by 10 m/min (393.70 ipm) until the preset feeder inching speed is reached If the wire electrode meets a ground earth connection, then the
-
wirefeeding is stopped and the wire electrode is retracted again by 1 mm (0.039 in.)
EN-US
Option 2
Thread the wire electrode in 1 mm steps (0.039 in. steps) – always press the wire-threading button for less than 1 second (tap)
If the wire electrode meets a ground earth connection, then the wirefeed­ing is stopped and the wire electrode is retracted again by 1 mm (0.039 in.)
IMPORTANT! If there is a ground earth connection with the contact tip, then before the wire-threading button is pressed, the wire electrode is re­tracted by pressing the wire-threading button until the wire electrode is short-circuit-free—however, this must not exceed 10 mm (0.39 in.) each time the button is pressed. If after the 10 mm (0.39 in.) wire retraction there is still a ground earth connection with the contact tip, then when the wire-threading button is pressed again, the wire electrode is retracted again by a maximum of 10 mm (0.39 in.). The process is repeated until there is no longer any ground earth connection with the contact tip.

Safety
Setup Regula­tions
WARNING!
Work performed incorrectly can cause serious injury and damage to property.
This setting work must only be carried out by trained and qualified person-
nel. Observe the safety rules in the OI, in particular the "Safety Inspection" sec-
tion.
The power sources have been tested according to protection class IP 23. This means:
Protection against solid foreign bodies larger than Ø 12 mm (0.47 in.)
-
Protection against spraywater up to an inclined angle of 60°
-
The welding system can be set up and operated outdoors in accordance with pro­tection class IP 23. However, the effects of direct moisture (e.g. from rain) must be avoided.
WARNING!
Toppling or falling devices can be deadly.
Securely set up the devices on a level and stable surface.
The ventilation channel of the power sources is an important safety device. When selecting the setup location, ensure that the cooling air can enter and exit un­hindered through the vents on the front and back. Any electrically conductive dust (e.g. from grinding work) must not be allowed to be sucked directly into the system.
Grid Connection The device is designed for the grid voltage listed on the rating plate. The fuse
protection required for the grid lead can be found in the "Technical Data" section. If mains cables or mains plugs are not included with your version of the appli­ance, attach the appropriate mains cable or mains plug in accordance with your country's standards.
CAUTION!
An under-dimensioned electrical installation can lead to serious damage.
The grid lead and its fuse protection should be designed to suit the existing
power supply. The technical data on the rating plate should be followed.

Creating a Refer­ence Program
The scope of supply for the laser welding head includes a metal gauge for the ex­act adjustment of the wire electrode position with respect to the laser focus. This gauge is mounted in the working area of the robot and is used to create a reference program for the series components.
WARNING!
This setting work must only be carried out by trained and qualified person­nel. Observe the safety rules in the OI, in particular the "Safety Inspection" sec­tion.
After the laser welding head is installed for the first time When programming a new part, if the x-, y- and z-values have changed on the adjustment units.
Create a reference program before welding the first series component
Requirement:
The laser welding head must be set up and fully connected.

Signal Sequence for LaserHybrid Welding
Safety
WARNING!
Work performed incorrectly can cause serious injury and damage to property.
The welding process may only be programmed by trained personnel.
Observe the safety rules in the OI, in particular the "Safety Inspection" sec-
tion
CAUTION!
Risk of damage to the optical fiber due to the laser welding head being perpen­dicular to the workpiece surface during welding.
If the laser optics unit is at 90° to the workpiece surface, then the laser beam is reflected directly into the laser optics. This may cause serious damage to the op­tical fiber.
Always guide the laser welding head to be trailing or leading!
NOTE!
When welding lots of short weld seams in direct succession, only switch off the CrossJet flow and external extraction system at the end of the entire process.
This will avoid contamination of the protective glass due to welding fumes.
