5 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 ... +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 manu-
facturer is not liable for damages cause by
misuse.
Ambient air must be free of dust, acids, corrosive gases
or other damaging substances!
6 Unit protection
This machine is protected electronically against over-
loading. Do not use fuses of higher amperage than
printed on the identification plate.
The machine is cooled using a fan.
Therefore, always ensure that the cooling air openings
are always uncovered.
Do not insert any objects into the ventilation slots. This
may damage the fan.
Never perform a welding operation when the fan is de-
fective. Instead, have the device repaired.
Switch-on duration (ED)
The switch-on duration (ED) is based on a work cycle of
10 minutes. ED 60% therefore means a welding dura-
tion of 6 minutes. After this, the device must cool down
for 4 minutes.
If the ED is exceeded then an integrated thermocouple
switches the machine off. When the device has cooled
down sufficiently, it switches itself back on.
7 Noise emission
The noise level of the unit is less than 70 dB(A), meas-
ured under standard load in accordance with EN 60974-
1 in the maximum working point.
8 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 in-
spections of welding systems, please contact
your authorised Lorch service centre.
9 Electromagnetic compatibility
(EMC)
This product is manufactured in conformance with the
current EMC standard. Please note the following:
Due to their high power consumption, welding ma-
chines can cause problems in the public power grid.
The mains connection is therefore subject to require-
ments with regard to the maximum permissible sys-
tem impedance. The maximum permissible system
impedance (Zmax) of the interface to the power grid
(mains connection) is indicated in the technical data.
If in doubt, please contact your power grid operator.
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 interfer-
ence
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
