M10 Welding ground connection
POSIMATIC PS30
is fitted with four ground connectors ( M10 ). They are made up of an
assembly with two brushes pushed by springs that rub against the plate ( M9 ).
The capacity of this welding ground connection (1000A for a 100% duty factor) is such that
it enables nearly all welding processes to be used.
In order to avoid overheating of the ground connection, it is advised that welding cables be
connected with a section compatible of course with the current conveyed and the duty factor.
This ground connection must be made to avoid deteriorating the ball bearings of the
positioner.
