4.5.6 Dimensional Accuracy
Generally, using the slowest possible speed (within
approved levels) will optimize part accuracy. Most
material thickness overlap for different voltages.
Select consumables to allow a lower arc voltage
and slower cutting speed.
4.6 Process Data
NOTICE
Recommended cutting speed and arc voltage will
give optimal cutting performance.
Small incremental adjustments may be needed due
to material quality, material temperature and specific
alloy. The operator should remember that all
cutting variables are interdependent. Changing one
setting affects all others and cut quality could
deteriorate. Always start at the recommended
settings.
Before attempting ANY corrections, check cutting
variables with the factory recommended settings/
consumable part numbers listed in the process
data.
