TROUBLESHOOTING (CONTINUED)
Check that the grounding
point and the metal being
cut are both clean, dry,
and free from all coatings
and paint. These sections
need to be able to conduct
electricity efficiently.
The Air pressure may be too high or too
low. Check the Air Pressure setting on
the regulator’s gauge.
Adjust the Air Regulator
to deliver only 60-65 PSI
to the Cutter.
