PART TO BE WELDED
The part to be welded must always be
connected to earth in order to reduce
electromagnetic emission. Much atten-
tion must be afforded so that the earth
connection of the part to be welded does
not increase the risk of accident to the
user or the risk of damage to other elec-
tric equipment.
When it is necessary to connect the part
to be welded to earth, you should make
a direct connection between the part
and the earth shaft. In those countries in
which such a connection is not allowed,
connect the part to be welded to earth
using suitable capacitors, in compliance
with the national regulations.
