10. TROUBLESHOOTING
10.1 WELDING DEVICE
FAULT CAUSE REMEDY
1 No welding current
Mains master switch on,
display remains off Mains cable interrupted Check mains cable and mains voltage
Device fuse blown Replace device fuse with identical
fuse (same type and value)
2 No welding current
Mains master switch on Welding cable connections interrupted Check plugged connections
Poor or zero contact to the workpiece Establish connection to the workpiece,
fasten contact clamps directly to the
workpiece
3 No welding current
Mains master switch on
Fault due to leakage current Switch device off and back on again
If fault reoccurs,
arrange for servicing of device
4 Mains fuse blows or automatic
circuit breaker trips Mains insufficiently fused or incorrect
automatic circuit breaker Fuse mains properly
Mains protection trips during idling Arrange for servicing of device
5 Poor welding characteristics Incorrect shielding gas Use inert shielding gas (Argon 4.6)
6 Poor ignition characteristics Electrode clamped loosely in
handpiece Tighten the clamping nut in the
handpiece (chap.11, no.38) by hand,
however, tighten
firmly .
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.
