SECTION 6 TROUBLESHOOTING
Torch and Cut Quality
Note:
This is oered as a general guide. Refer to your torch manual for specics on your equipment
Problem Possible Cause Corrective Action
Reduced Electrode Life 1) Skeleton cutting
2) Height control problems.
3) Piercing stando too low.
4) Starting on edges with continuous pilot
arc.
5) Gas pressures too high or low.
6) Coolant ow below 3/4 GPM (0.5 l/
sec).
7) Gas or water leaks in torch
1) Cutting skeletons to facilitate their
Removal from the table can ad-
versely aect electrode life by:
a) Causing the torch to run o the
work.
b) Continuous pilot arc edge starts.
c) Greatly increasing the frequency of
starts. This is mainly a problem for
O2 cutting and can be alleviated by
choosing a path with a minimum
number of starts.
d) Increased likelihood that the plate
will spring up against the nozzle
causing double arc. Careful atten-
tion by the operator, increasing
standoff and reducing cutting
speeds will help mitigate these
conditions.
If the machine is equipped with a gas
torch, it may be more practical to use it
for skeleton cutting.
2) See crashing/diving in item 6.
3) Increase piercing stando
4) Position torch more carefully or use
waste plate to start on.
5) Make appropriate adjustment
6) Check coolant level and ow
