Instruction Manual
Notes:
• Minimum N
2
inlet supply pressure remains at one setting of 150 psi (10.3 bar) for all material thickness.
• Water chiller pump outlet pressure remains between 175-185 psi (12-12.8 bar) for all material thickness.
• N
2
flow rate at full scale is 374 scfh (176 l/min) @ 150 psi (10.3 bar) inlet pressure.
• Set initial torch height (before piercing) to approximately twice the Torch Standoff distance for the material you
are cutting.
Note: If arc does not transfer when set at twice the torch standoff (in the case of thick metal being cut at high
current), gradually lower the initial height of the torch until transfer occurs.
