Ambient conditions
Temperature range of ambient air:
in operation: -10 °C ... +40 °C (+14 °F to +104 °F)
transport and
storage: -25 °C ... +55 °C (-13 °F to +131 °F)
Relative humidity:
up to 50 % at 40 °C (104 °F)
up to 90 % at 20 °C (68 °F)
Operation, storage and transport may only
be carries out within the ranges indicated!
Use outside of this range is considered
not used with its intended purpose. The
manufacturer is not liable for damages
cause by misuse.
Ambient air must be free of dust, acids, corrosive gases
or other damaging substances!

General regulation of use
The device is intended for feeding in welding wire (filler
material) in combination with a welding power source
under commercial and industrial usage conditions.

UVV inspection
Operators of commercially-operated welding systems
are obliged to have regular safety inspections of the
equipment carried out in accordance with EN 60974-4.
Lorch recommends inspections at 12 month intervals.
A safety inspection must also be carried out if modifica
-
tions or repairs have been made to the system.
Improper UVV inspections can destroy
the system. For more information on UVV
inspections of welding systems, please
contact your authorised Lorch service
centre.

Noise emission
The noise level of the unit is less than 70 dB(A),
measured under standard load in accordance with EN
60974-1 in the maximum working point.

Electromagnetic compatibility
(EMC)
This product is manufactured in conformance with the
current EMC standard. Please note the following:
The machine is intended for welding in both commer-
cial and industrial applications (CISPR 11 class A).
Use in other surroundings (for example in residential
areas) may disturb other electronic devices.
Electromagnetic problems during start-up can arise
in:
– mains cables, control cables, signal and telecom-
munication lines near the welding or cutting ma-
chine
– TV/radio transmitters/receivers
– Computers and other control devices
– Protection equipment such as alarm systems
– Pacemakers and hearing aids
– Measurement and calibration devices
– Equipment with too little protection against inter-
ference
If other equipment is disturbed, it may be necessary to
provide additional shielding.
The affected area may go beyond the boundaries of
the property concerned. This depends on the layout
of the building, and the other activities that may be
going on there.
Please use the machine in compliance with the manu-
facturer's instructions. The operator of the equipment is
responsible for the installation and use of the machine.
Furthermore, the owner is responsible for eliminating
the interference caused by electromagnetic fields (pos
-
sibly with technical assistance by the manufacturer).
