Faults Cause of fault Troubleshooting
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.
„
Reduce the working
speed.
„
Several cycles necessary.
„
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.
„
Check the air filter, in-
crease 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.
