Transport And Storage; Machine Cooling; Workpiece Lead, General; Notes On The Installation Of Welding Current Leads - EWM Tetrix 352 Synergic Operating Instructions Manual

5.1.2.2

Transport and storage

Storage in an enclosed space, temperature range of the ambient air:
•
-30 °C to +70 °C
Relative air humidity
•
Up to 90% at 20 °C
5.1.3

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!
5.1.4

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!
5.1.5

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).
