HF-arc is not created?
Bad ignition?
Plasma burner
is not ready
8
for operation?
Sparks fly upwards, instead of
down through the material?
Initial cut but not completely
drilled through?
Slag formation on interfaces?
Consumables wear quickly?
The burner switch is faulty.
„
Soldering point on the burner
„
switch or plug loosened.
Valve/manometer fails.
„
Burner wear parts damaged
„
or worn.
Current switch is
„
switched off.
Air transmission is restricted.
„
Workpiece is not connected
„
to the earthing terminal.
The plasma beam does not
„
penetrate the material.
Burner sleeve
is too far
8c
„
away from the material.
Material was probably not
„
earthed properly.
Lifting speed is too quick.
„
Potential connection
„
problem.
Tool/material creates heat.
„
Cutting speed too low or
„
current too high.
Plasma burner component
„
parts are worn
,

Performance was
„
overstretched.
Arc control time exceeded.
„
Incorrect plasma burner
„
assembly.
Insufficient air supply,
„
pressure too low.
Faulty air compressor.
„
Replace electrode.
„
Change wear parts.
„
Switch the current switch
„
to "on".
Another indication of this is
„
a green flame. Check the
air supply.
Check the connections.
„
Increase the current.
„
Reduce the gap between the
„
burner sleeve
material.
Check the connection for
„
correct earthing.
Reduce the speed.
„
Check all connections.
„
Allow the material to cool
„
down and then continue
cutting.
Increase the speed and/or
„
,
,
reduce the current until the
8c
8d
slag has been reduced to a
minimum.
Check and replace worn
„
parts.
Material too thick, increase
„
the angle to avoid material
from being blown back into
the tip.
Do not control the arc for
„
more than 5 seconds. You
can also start with contact
between the burner sleeve
and metal or with a
8c
3 mm distance to the metal.
Check the performance of
„
the external air compressor
and make sure the pressure
is 4–4.5 bar.
