Establishing a
ground earth
connection
NOTE!
When establishing a ground earth connection, observe the following points:
▶
Use a separate return lead cable for each power source
▶
Keep the plus cable and return lead cable together as long and as close as
possible
▶
Physically separate the welding circuits of individual power sources
▶
Do not route several return lead cables in parallel;
if parallel routing cannot be avoided, keep a minimum distance of 30 cm
between the welding circuits
▶
Keep the return lead cable as short as possible, provide a large cable cross-
section
▶
Do not cross return lead cables
▶
Avoid ferromagnetic materials between the return lead cable and the inter-
connecting hosepack
▶
Do not wind up long return lead cables - coil effect!
Lay long return lead cables in loops
▶
Do not route return lead cables in iron pipes, metal cable conduits or on
steel rails, avoid cable ducts;
(routing of plus cables and return lead cables together in an iron pipe does
not cause any problems)
▶
If there are several return lead cables, separating the grounding points on
the component so that they are as far away from one another as possible is
recommended, as well as preventing crossed current paths from occurring
underneath the individual arcs.
▶
Use compensated interconnecting hosepacks (interconnecting hosepacks
with integrated return lead cable)
Connecting the return lead cable
1
Plug the return lead cable into the
(-) current socket
2
Lock the return lead cable in place
3
Use the other end of the return
lead cable to establish a connec-
tion to the workpiece
