Troubleshooting / Maintenance and care
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 are worn
8b
,
8c
,
8d
,
8e
.
Workpiece no longer
connected to the grounding
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.
Burner sleeve
8c
is not straight
Metal is too thick.
Plasma burner component
parts are worn
8b
,
8c
,
8d
,
8e
.
Slow down the working speed
Adjust the inclination.
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. You can
also start with contact
between the burner sleeve
8c
and metal or with a 3.2 mm
distance to the metal.
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 parts displayed in Figure F are the
electrode
8d
, diffuser
8e
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 thread is released.
The new electrode must be screwed into
its bracket and blocked but not tightened
up to the stop.
