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 pos-
sible 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 + in-
termediate 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.
