Slag formation on
interfaces?
Tool/material creates heat.
Cutting speed too low or
current too high.
Plasma burner component
parts
8b
,
8c
,
8d
are worn.
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.
Arc stops during
cutting?
Cutting speed too low.
Plasma burner
8
is held too
high and too far away from
the material.
Plasma burner component
parts
8b
,
8c
,
8d
are worn.
Workpiece no longer
connected to the earthing
cable.
Increase the cutting speed until
the problem no longer exists.
Lower the plasma burner
8
to
the recommended height.
Check and replace worn
parts.
Check the connections.
Insufficient
penetration?
Cutting speed too fast.
Metal is too thick.
Plasma burner component
parts
8b
,
8c
,
8d
are worn.
Slow down the working
speed.
Several cycles necessary.
Check and replace worn
parts.
Consumables
wear quickly?
Performance was over-
stretched.
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.
Check the air filter, increase
the air pressure.
Check the performance of the
air compressor and make sure
the inlet pressure is at least
100 PSI (6.8 bar).
• Maintenance and care
• Maintaining the burner
The consumables displayed in Figure F
are the electrode
8d
and the burner
sleeve
8c
. They can be replaced once
the nozzle clamping sleeve
8b
has been
unscrewed.
The electrode
8d
must be replaced
if there is a crater of approximately
1.5 mm depth in the centre.
ATTENTION!
f
To unscrew the electrode, do not apply
irregular pressure, gradually increase
pressure until the electrode comes out.
Then screw in the new electrode into the
holder.
