note:
This is offered as a general guide. Refer to your torch manual for specifics on your equipment
Problem Possible Cause Corrective Action
Reduced Electrode Life 1) Skeleton cutting
2) Height control problems.
3) Piercing standoff too low.
4) Starting on edges with continuous pilot
arc.
5) Gas pressures too high or low.
6) Coolant flow 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 affect electrode life by:
a) Causing the torch to run off 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 standoff
4) Position torch more carefully or use
waste plate to start on.
5) Make appropriate adjustment
6) Check coolant level and flow
