TROUBLESHOOTING
pieces have been removed from a plate) to facilitate
their removal from the table can adversely affect
electrode life by:
•
Causing the torch to run off the work.
•
Continuous Pilot Arc edge starts
•
Greatly increasing the frequency of starts. This
is mainly a problem for O
alleviated by choosing a path with a minimum
number of starts.
•
Increase likelihood that the plate will spring up
against the nozzle causing a double arc. This
can be mitigated by careful operator attention
and by increasing standoff and reducing cutting
speeds.
If possible, use a gas torch for skeleton cutting.
•
Torch diving is usually caused by a change in
arc voltage when an automatic height control is
in use. Usually the voltage change is the result
of plate falling away from the arc. These
problems can effectively be eliminated by
disabling the height control and extinguishing
the arc earlier when finishing the cut on a falling
plate.
•
Diving can also be caused by a faulty height
control.
Position torch more carefully or start on adjacent
scrap material.
The nozzle may be damaged if the torch hits a
flipped up part.
