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 hand
piece
Tighten the clamping nut in the
handpiece (chap.11, no.41) 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.
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.

PROBLEMS WITH ELECTRICAL COMPONENTS
A
The LED illumination fails to
operate
Cable not connected.
Connect the plug to the connecting
socket (5) marked with the yellow
illumination symbol on the PUK04.
LED faulty
Exchange LED unit (only use original
replacement LED units from Lampert)
B
Eye protection system (shutter)
fails to operate
Cable connected incorrectly
Connect the plug to the designated
socket (3) marked with the red eye
protection symbol on the PUK04.
Eye protection filter faulty
Arrange to have eye protection unit
replaced by qualified personnel
IMAGE QUALITY
D
Poor resolution
Oculars dirty.
Clean oculars.
E
Marks or soiling in field of vision
Oculars dirty.
Clean oculars.
Protective glass dirty
Clean or exchange protective glass
* Note: Marks in the field of vision can also be caused by soiling in the interior of the oculars. For this reason, it is
recommended to have the lenses cleaned by an authorised customer service engineer
PROBLEMS WITH MECHANICAL COMPONENTS
F
Focus is not retained
The sight slides down
Readjust the tension of the focusing
knob
