General regulation of use

This machine is intended for use in the commercial and
industrial sector. It is portable and is suitable for opera-
tion on the mains supply or also on a power generator.
‰ The machine is intended for DC electrode welding of
– unalloyed steels, low and high-alloy steels
– nickel and its alloys
‰ Together with a TIG welding torch, the machine is
suitable for TIG welding with direct current of
– unalloyed steels, low and high-alloy steels
– copper and its alloys
– nickel and its alloys
– special metals like titanium, zirconium and tanta-
lum.
‰ Together with a wire feed case, the machine is suit-
able for MIG welding with
– solid wire (MIG/MAG),
– flux-cored wire.

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 about UVV
inspections of welding systems, please
contact your authorised Lorch service cen-
tre.

Unit protection

This machine is protected electronically against overload-
ing. Do not use fuses of higher amperage than printed on
the identification plate.
8

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.

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
- 6 -
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 area
– 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 distur-
bances
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
disturbances caused by electromagnetic fields.

Transport

For transport using mechanical lifting
gear (e.g. cranes etc.) only the handle
may be used as the hoisting point. Use
suitable load-bearing equipment. Do
not use a fork-lift truck or similar device
to lift the machine by its housing. The
carrying strap is exclusively for trans-
port by a person.
