Dual Connection of Workpiece Ground Cable
The welding current return takes place via the Workpiece Ground Cable, which must
be connected as follows to one of the Workpiece Ground Cable sockets (
Item 3
of
, Page 7
) on the front panel of the NCD+.
Workpiece Ground Cable Dual Connection (X3)
Connect the Workpiece Ground Cable plug into one of the proper NCD+ sockets.
Turn the Workpiece Ground Cable plug 1/3 to the right clockwise to secure the
connection.
Place the 2 ground clamps on the opposite ends of the weld area to minimize arc blow.
Prior to to any connection task, the NCD+ welding unit must be switched off
and the input power switch must be in the >>0<< position.
1.2.5
Connection of the Workpiece
When connecting the workpiece ground terminals, attention must be paid to the following:
The workpiece ground terminals must be connected directly to the workpiece or to the workpiece fixture
(welding bench, welding grid). Steel constructions, tracks, pipelines, etc. may not be used as current
conductors, unless they themselves are the workpieces to be welded. The welding current circuit may
not be earth grounded. The exception is the workpiece itself or the workpiece fixture are earth
grounded compulsorily (pipelines, shipbuilding, etc.). Place the workpiece ground terminals, if possible,
at the same distance from the point of welding when two ground clamps are used.
