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.
