be regulated?
Compressed air hose
damaged or faulty.
Valve/manometer fails.
New connection of the hose.
HF-arc is not
created?
The burner switch is faulty.
Soldering point on the burner
switch or plug loosened.
Valve/manometer fails.
Renew electrode.
Bad ignition? Burner wear parts damaged
or worn.
Check HF spark gap.
Change wear parts.
Set spark gap.
Plasma burner
8
is not ready for
operation?
Current switch is switched off.
Air transmission is restricted.
Workpiece is not connected to
the ground terminal.
Switch the current switch

Another indication of this is
a green flame. Check the air
supply.
Check the connections.
Sparks fly
upwards, instead
of down through
the material?
Burner sleeve
8c
does not
penetrate the material.
Burner sleeve
8c
is too far
away from the material.
Apparently material was not
grounded properly.
Lifting speed is too quick.
Increase the current.
Reduce the distance between
the burner sleeve
8c
and
material.
Check the connection for
correct grounding.
Reduce the speed.
Initial cut but not
completely drilled
through?
Potential connection problem. Check all connections.
Slag formation on
interfaces?
Tool/material creates heat.
Cutting speed too low or
current too high.
Plasma burner component
parts are worn
8b
,
8c
,
8d
,
8e
.
Allow the material to cool
down and then continue
cutting.
Increase the speed and/or
reduce the current until the
slag has been reduced to a
minimum.
Check and replace worn
parts.
