Notes on the installation of welding current leads
• Incorrectly installed welding current leads can cause faults in the arc (flickering).
• Lay the workpiece lead and hose package of power sources without HF igniter (MIG/MAG) for
as long and as close as possible in parallel.
• Lay the workpiece lead and hose package of power sources with HF igniter (TIG) for as long as
possible in parallel with a distance of 20 cm to avoid HF sparkover.
• Always keep a distance of at least 20 cm to leads of other power sources to avoid interferences
• Always keep leads as short as possible! For optimum welding results max. 30 m (welding lead
+ intermediate hose p torch lead).
Figure 5-1
Use an individual welding lead to the workpiece for each welding machine!
Figure 5-2
Fully unroll welding current leads, torch hose packages and intermediate hose packages. Avoid
loops!
Always keep leads as short as possible!
Lay any excess cable lengths in meanders.
