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