with grounded neutral conductor or single phase-three-
wire system with grounded neutral conductor) socket and
extension cable must have a functional protective con-
ductor.
‰ Wear protective clothing, leather gloves and a leather
apron.
‰ Protect the welding area with curtains or mobile screens.
‰ Do not use welding equipment to thaw out frozen water
pipes or lines.
‰ In closed containers, under cramped conditions, and in
high electrical risk areas, only use machines with the S sign.
‰ When taking a break, switch off the machine and close the
valve on the gas cylinder.
‰ Secure the gas cylinder with a chain to prevent it falling
over.
‰ Disconnect the mains plug from the mains before chang-
ing the place of installation or making repairs to the ma-
chine.
Please heed the safety regulations which apply to your coun-
try. Subject to change.

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
carried out within the ranges indicated! Usage
outside of this range is considered to be not
as intended. The manufacturer is not liable for
damages cause by misuse.
Ambient air must be free of dust, acids, corrosive gases or oth-
er damaging substances!
5

General regulation of use

This equipment is intended for welding steel, aluminium and
alloys, in commercial and industrial environments.
6

Machine protection

This machine is protected electronically against overloading.
Do not use fuses of higher amperage than printed on the iden-
tification plate.
Close the side cover before starting any welding work.
7 Accident prevention inspection
(UVV)
Operators of commercially-operated welding systems are
obliged to have regular safety inspections of the equipment
01.21
carried out in accordance with EN 60974-4. Lorch recom-
mends inspections at 12 month intervals.
A safety inspection must also be carried out if modifications or
repairs have been made to the system.
Improper accident prevention inspections can
destroy the system. For more information on
accident prevention 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 un-
der standard load in accordance with EN 60974-1 in the maxi-
mum working point.
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 machines
can cause problems in the public power grid. The mains
connection is therefore subject to requirements with re-
gard to the maximum permissible system impedance. The
maximum permissible system impedance (Zmax) of the
interface to the power grid (mains connection) is indicat-
ed in the technical data. If in doubt, please contact your
power grid operator.
‰ The machine is intended for welding in both commercial
and industrial applications (CISPR 11 class A). Use in other
surroundings (for example in residential areas) may dis-
turb other electronic devices.
‰ Electromagnetic problems during start-up can arise in:
– Mains cables, control cables, signal and telecommuni-
cation lines near the welding or cutting machine
– 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 pro-
vide 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 manufacturer's
instructions. The operator of the equipment is responsible for
the installation and use of the machine. The owner is responsi-
ble for eliminating the interference caused by electromagnetic
fields (possibly with technical assistance by the manufacturer).
