Check for compliance with provisions
stipulated in the German BGV
The operating company of commercially used
welding equipment is obliged to have the appliances
checked in accordance with directive EN 60974-4
at regular intervals appropriate for the frequency
of use. Würth recommends having the appliance
checked every 12 months.
Additional safety checks have to be performed after
modifying or repairing the appliance.
Attention !
Improper checks for compliance with
accident prevention regulations may
result in destruction of the machine.
Please contact an authorised Würth
service point for more information on
checking the compliance with accident
prevention regulations.
Electromagnetic compatibility (EMC)
This appliance conforms to the current EMC
standards.
Please note:
▸
Welding machines consume so much power that
they may affect public electricity networks. For this
reason the mains supply is subject to requirements
regarding the maximum permissible network
impedance. The maximum permissible mains
impedance (Z
) of the interface to the mains grid
max
(mains power supply) is specified in the technical
data. Contact the electricity network operator if
required.
▸
The appliance is intended for welding both
in commercial and industrial environments
(CISPR 11 class A). Using the appliance in an-
other environment (e.g. in a residential area) may
affect electrical equipment in that area.

During start-up, electromagnetic problems may be
caused in:
• Power cables, control lines, signal and telecom-
munication lines in the vicinity of the welding /
cutting appliance
• TV and radio transmitters and receivers
• Computers and other control equipment
• Security equipment in commercial buildings
(e.g. alarm systems)
• Cardiac pacemakers and hearing aids
• Calibrating and measuring equipment
• Appliances with insufficient interference resist-
ance
• If any other facility or equipment in the
surrounding area is affected, additional
protective barriers may become neces-
sary.
▸
The surrounding area to be taken into consider-
ation may extend beyond the boundaries of the
premises. This depends both on the type of the
building and on the other activities performed at
the site.
▸
Always observe information and instructions
provided by the manufacturer when operating the
appliance. The company operating the appliance
is responsible for the setup and the operation of
the appliance.
If electromagnetic disturbances occur, the operating
company is responsible for the elimination of this
disturbances (with technical help from the manufac-
turer if necessary).
