Earth ground Cable Connection (X3)
Use cable resistance monitor (see section 3.15) to continuously monitor loose

Connection of the workpiece
When connecting the earth ground terminals attention must be paid to
the following:
1.
The earth 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 are themselves the workpiece to be welded.
2.
The welding current circuit may not be earth grounded.
Exception: The workpiece itself or the workpiece fixture are earth
grounded compulsorily (pipelines, shipbuilding, etc.).
3.
Place the earth ground terminals if possible at the same distance
from the point of welding when two ground clamps are used.
Note!
