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!
5 General regulation of use
This equipment is intended for welding steel, aluminium and
alloys, in commercial and industrial environments.
‰ The device used for welding the following with direct cur-
rent
– non-alloyed, low-alloy and high-alloy steels,,
– copper and its alloys

– special metals such as titanium, zirconium and tanta-
lum,
‰ for TIG welding with alternating current of
– aluminium and its alloys
– magnesium and its alloys
‰ and for MMA welding.
6 Unit protection
This machine is protected electronically against overloading.
Do not use fuses of higher amperage than printed on the iden-
tification plate.
7 Noise emission
The noise level of the unit is less than 70 dB(A), meas-ured un-
der standard load in accordance with EN 60974-1 in the maxi-
mum working point.

Electromagnetic compatibility (EMC)
8 UVV inspection
Operators of commercially-operated welding systems are ob-
liged to have safety inspections of the equipment carried out
regularly in accordance with EN 60974-4. Lorch recommends
inspection intervals of 12 months.A safety inspection must
also be carried out after altera-tions or repair of the system.
Improper UVV inspections can destroy the sys-
tem. For more information on UVV in-spections
of welding systems, please con-tact your au-
thorised 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 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 indica-
ted 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 area
– TVs/radios
– Computers and other control equipment
– Protection equipment such as alarm systems
– Pacemakers and hearing aids
– Equipment for measurement and calibration
– Equipment with too little protection against distur-
bances
If other equipment is disturbed it may be necessary to provide
additional shielding.
‰ The affected area can be bigger than your premises/pro-
perty. This depends on the building, etc.
Please use the machine in compliance with the manufacturer's
instructions. The machine operator is responsible for installati-
on and use of the machine. Furthermore, the owner is respon-
sible for eliminating the disturbances caused by electromag-
netic fields.
