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 package + torch lead).
Use an individual welding lead to the workpiece for each welding machine!
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.
