GENERAL
This equipment has been manufactured in conformity with IEC 60974 -1 / IEC 60974 – 10 standard.
The Standard determines the limits for electromagnetic interference.
However, such limits are by far dependent on the use and installation of the equipment.
Limits required by Standard may be insufficient for the elimination of interference. In such case, special measures shall be put in
place in order to further reduce the interference.
INSTALLATION AND USE
The user has the responsibility for the correct installation and use of the equipment.
In the event that electromagnetic interference is found, the user, with the assistance of the equipment manufacturer, must take all
measures to reduce the electromagnetic interference.
-
Before installing the equipment, the user must assess the electromagnetic interference which may be generated in the surrounding
area resulting from the activities run within the workshop area. For example: telephone exchanges, computers, NC machines, bearers
of vital electronic equipment (pacemakers, acoustic apparatuses, etc...).
-
The arc welder is to be connected to the mains according to the manufacturer indications. In the event of major inter
ference, further measures shall be taken to reduce such electromagnetic interference.
-
DO NOT modify the arc welder. Keep the machine always well maintained.
-
Ground and welding cables must be run at floor level and their length must not be excessive.
-
The user must keep himself well insulated from all metal, grounded components.
