7 Oxidation and rusting
Excessive gas pressure Reduce flow rate - approx. 2 l/min is
recommended
8 Severe oxidation of the welding
points
Incorrect shielding gas Use inert shielding gas (Argon 4.6)
9 Tungsten inclusions in base
material
Excessive pressure of the electrodes
on the workpiece
Touch workpiece with extremely light
pressure.
10 Tungsten electrode welds to
workpiece
Excessive pressure of the electrodes
on the workpiece
Touch workpiece with extremely light
pressure.
11 Tungsten electrode melts off
immediately
Electrode sharpened too steeply Use the recommended angle of
grinding (approx. 15°)
12 Static discharge over the surface of
the device
Special local conditions Use special foot mat for the
workspace
13 Device begins to weld immediately
when touching the workpiece (no
gas pre-flow)
Fault Immediately shut down the device,
arrange for servicing.
