The sound level of the unit is smaller as 70 dB (A) measured
at standard load conforming EN 60 974 at the max. work-
point.
Depending on the operation, users of commercially operated
welding systems are obliged to have safety inspections of the
equipment carried out regularly in accordance with
VDE 0544-207. ELEKTRON recommends inspection periods
of 12 months.
A safety inspection must also be carried out after alterations
or repair of the system.
! Caution ! : Improperly carried out UVV inspections can de-
stroy the system.
For more information on UVV inspections of welding systems,
please contact your authorized service center.
This product is manufactured conform to the current EMV
standard. Please notice following items:
 The unit is for welding under commercial or industrial con-
ditions. The use in other surroundings (for example in res-
idential areas) may disturb other electric devices.
 During welding electromagnetic problems can be caused
at:
– Mainscables, controlcables, connections for telecom-
munication
– TV / Radio
– Computer and other similar devices
– Protection devises as for example alarm systems
– Pacemakers and hearing aids
– Devices for measure and calibrate
– Devices with less protection against disturbances
If other devices are disturbed it may be necessary to pro-
tect additionally.
 The affected area can be bigger than your premises /
property depends of the building etc.
Please use the unit conform to the instructions of the manu-
facturer. The user is responsible for installation and use of the
machine. Furthermore the user is responsible to eliminate the
disturbances caused by electromagnetic fields.
