Workpiece lead, general

Risk of burning due to incorrect welding current connection!
If the welding current plugs (machine connections) are not locked or if the workpiece
connection is contaminated (paint, corrosion), these connections and leads can heat up
and cause burns when touched!
• Check welding current connections on a daily basis and lock by turning to the right when
necessary.
• Clean workpiece connection thoroughly and secure properly. Do not use structural parts of
the workpiece as welding current return lead!
5.1.4

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 + inter-
mediate hose package + torch lead).
