done with open jaws of the
extraction tool.
3b No
or
little
material removed
when milling on
the electrode or,
no clamping of the
extractor on the
electrodes, while
signal of the speed
evaluation
is
displayed (3 LED,
with
speed
evaluation).
Milling tool / extractor tool
turns in the wrong direction.
The
correct
direction
of
rotation is clockwise looking at
the top of the milling tool.
Ensure phases are correct in
power supply. The phase
change must be made in the
feed ensuring correct rotation
even when later replacing the
drive or device.
Milling tool or extractor tool is
damaged or dull.
Replace tool.
Welding gun has low closing
pressure for milling.
Check closing pressure and
adjust if necessary.
3c No
or
little
material removed
when milling on
the
electrode.
Signal of the speed
evaluation is (3
LED, with speed
evaluation)
not
available.
Milling tool does not rotate or
too slow because there are
errors according to items (1)
and (2).
Review solutions described in
points (1) and (2).
The device does not run with
full power in three phases
(audible by engine hum).
The power supply must be
checked and corrected if
necessary. Supply line to the
electric motor and connections
in the terminal board of the
drive to be checked.

regularly clogs; the
electrode life is
shortened.
Blow-off or chip removal does
not work properly.
The air jet of the exhaust
nozzles must be directed into
the milling tool. Replace parts if
damaged.
