Accident prevention 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 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.

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 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 manufactur-
er's instructions. The operator of the equipment is responsi-
ble for the installation and use of the machine. The owner is
responsible for eliminating the interference caused by elec-
tromagnetic fields (possibly with technical assistance by the
manufacturer).
