Emc Measures; Specific Hazards - Fronius Laser hybride Instructions De Service

In the case of automated MIG/MAG applications, ensure that only an insulated wire elec-
trode is routed from the welding wire drum, large wirefeeder spool or wirespool to the wire-
feed unit.

EMC measures

Warning, electromagnetic field. Electromagnetic fields may cause as yet unknown dam-
age to health.
It is the operator's responsibility to ensure that no electromagnetic interference occurs in
electrical and electronic devices.
If electromagnetic interference is found to be occurring, the owner/operator is obliged to
take all necessary measures to prevent this interference.
Check for possible problems, and check and evaluate neighbouring devices' resistance to
interference according to national and international requirements:

-
-
-
Individuals with pacemakers must seek advice from their doctor before approaching the
welding work area.

Specific hazards

Risk of injury to the eyes from the laser beam. In addition to the protective visor with regu-
lation UV filter element, ensure that all persons wear regulation laser safety goggles to pro-
tect their eyes from laser beams. You should still ensure that nobody can accidentally look
into the laser beam.
With highly shiny, reflective workpiece surfaces, there is a further danger caused by reflect-
ed and scattered laser radiation. Suitable precautions must be taken to ensure that all per-
sons in the area are sufficiently protected from scattered laser radiation.
Keep hands, hair, clothing and tools away from moving parts. For example:
-
-
-
-
-
Do not reach into the rotating cogs of the wire drive or into rotating drive components.
Safety devices
Power, signal and data transfer lines
IT and telecommunications devices
Measuring and calibrating devices
The health of persons in the vicinity, e.g. users of pacemakers and hearing aids
Mains supply
- If electromagnetic interference arises despite the correct mains connection, addi-
tional measures are necessary (e.g. use of a suitable line filter)
Welding power-leads
- must be kept as short as possible
- must be laid close together (also to avoid EMC problems)
- must be laid apart from other leads
Equipotential bonding
Earthing of the workpiece
- If necessary, establish an earth connection using suitable capacitors.
Shielding, if necessary
- Shield off other nearby devices
- Shield off entire welding installation
Fans
Cogs
Rollers
Shafts
Wirespools and welding wires
