5.1.2 Machine cooling
Insufficient ventilation results in a reduction in performance and equipment damage.
• Observe the ambient conditions!
• Keep the cooling air inlet and outlet clear!
• Observe the minimum distance of 0.5 m from obstacles!
5.1.3 Workpiece lead, general
CAUTION
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!
