Troubleshooting
– Appendix 3
PROBLEM
POSSIBLE CAUSE
SOLUTION
Insufficient cut
penetration
Cutting speed too fast
Insufficient current
Worn or damaged torch
electrodes
Beginning and
end of cut not
severed
Torch positioning
Tilt the top of the torch towards the direction of travel as
you start the cut. Tilt it away from the direction of travel
when you are finishing the cut.
Dross build up on
parts of the cut
Cutting speed too slow or
not consistent
Try keeping a constant and steady cut speed for a set
current
Material getting too hot
Allow material to cool before continuing the cut
Current too high
Consumables
wear quickly
Air pressure too low
Re-check gauge pressure remains at 60psi when the cut
switch is actuated and remains at 60psi for the duration
of the cut.
Torch position
Tilt the top of the torch toward the direction of travel
when cutting the thickest material. This will reduce the
blow back into the torch tip.
Poor maintenance
Frequently clean the dross off the cutting tip using the
wire brush provided.
Cut is not vertical Torch position
The torch cuts in the direction that the plasma arc is
pointed. Keep the torch vertical for a vertical cut. The tip
can be angled to produce a weld prep if this is required
on the material being cut.
Torch will not
switch off when
cut switch
released
Cut switch problem
Check the cut switch contacts at the machine end of
cable for correct on/off circuit
Electronic Fault in unit
