inlet pressures remain at one setting of 120 psi (8.2 bar) for all material thickness.
Minimum N
2
inlet pressures remain at one setting of 150 psi (10.3 bar) for all material thickness.
O

flow rate at full scale is 127 scfh (60 l/min) @ 120 psi (8.2 bar) inlet pressure.
N
2
flow rate at full scale is 374 scfh (176 l/min) @ 150 psi (10.3 bar) inlet pressure.
Water chiller pump outlet pressure remains between 175-185 psi (12-12.8 bar) for all material thickness.
Set initial torch height (before piercing) to approximately twice the Torch Standoff distance for the material you
are cutting.
