HF-arc is not created?
„
The burner switch is faulty.
„
Soldering point on the burner
switch or plug loosened.
„
Valve/manometer fails.
„
Replace electrode.
Bad ignition?
„
Burner wear parts damaged
or worn.
„
Change wear parts.
Plasma burner
8
is not ready
for operation?
„ Current switch is
switched off.
„ Air transmission is restricted.
„ Workpiece is not connected
to the earthing terminal.
„ Switch the current switch
to “on”.
„ Another indication of this is
a green flame. Check the
air supply.
„ Check the connections.
Sparks fly upwards, instead of
down through the material? „ The plasma beam does not
penetrate the material.
„ Burner sleeve
8c
is too far
away from the material.
„ Material was probably not
earthed properly.
„ Lifting speed is too quick.
„ Increase the current.
„ Reduce the gap between the
burner sleeve
8c
and
material.
„ Check the connection for
correct earthing.
„ 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.
Consumables wear quickly?
„
Performance was
overstretched.
„
Arc control time exceeded.
„
Incorrect plasma burner
assembly.
„
Insufficient air supply,
pressure too low.
„
Faulty air compressor.
„
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
8c
and metal or with a
3 mm distance to the metal.
„
Check the performance of
the external air compressor
and make sure the pressure
is 4–4.5 bar.
