TCC
For a minimum of
200 milliseconds, the
nitrogen (N
2
) inlet pressure
(P4) in the torch connect
console is less than 5.52 bar
(80 psi) or more than
8.61 bar (125 psi).
If you have a cutting system equipped with a Core
or VWI gas connect console, refer to Gas inlet
pressure codes (768 – 771) on page 337.
If you have a cutting system equipped with a
OptiMix gas connect console, refer to Process-gas
inlet pressure in the torch connect console
diagnostic codes (702, 705, 769, 770) for
OptiMix-equipped cutting systems on page 334.
