Gas flow test
Checks the gas flow from the Gas Console through the torch. Will isolate flow errors in the torch leads,
consumables, gas leads, and/or gas console.
Items Needed: See parts list for details
#3 Inert to Right Hand ‘A’ Adapter (N 2 )
#8 Small Orifice Assembly
#9 Large Orifice Assembly
#10 100A Mild Steel Nozzle/Shield Assembly
#11 100A Swirl-ring Assembly
#11a 100A Electrode
#17 Inlet Manifold Assembly
#18 Slip-on Torch Cap Assembly
#19 Regulator Assembly
#21 Pressure Transducer Manifold Assembly
#32 Right Hand ‘A’ Hose Assembly (2)
Set-Up
1 – Install Inlet manifold assembly to Inlet manifold of gas console.
2 – Connect input hose of the inlet manifold to the outlet side of the regulator assembly.
3 – Connect one of the hose assemblies to the inlet side of the regulator assembly.
4 – Connect the other end of the hose assembly to the Inert Adapter.
5 – Connect the nitrogen supply line into the inert adapter.
6 – Install the 100A consumable parts into the torch.
7 – Install the slip-on torch cap assembly to the end of the torch. Make sure thumb screws tighten into the groove
on the retaining cap.
8 – Connect hose end of the torch cap assembly to the pressure transducer manifold assembly. Make sure the
shut-off lever is in the ON position.
9 – Connect the second hose assembly to the pressure transducer manifold.
10 – Connect opposite end of the Hose Assembly to the large orifice assembly.
11 – Connect Pressure Transducer Manifold Assembly cable to J2 on the gas console board (PCB2).
12 – Set pressure at regulator assembly to 100 psi (6.9 bar). Set gas pressure at source (N
2
) to 120 psi (7.3 bar).
Before running the gas flow test, check the calibration of the 4 pressure transducers.
To check the calibration perform the following functions:
1 – Turn the gas shut-off lever on the pressure transducer manifold to the OFF position.
2 – Manually turn SV5, SV10, SV11, SV12, SV13, and SV23 ON.
3 – Read the pressure for PT1, PT2, PT3 and PT4.
4 – Values should be within +/- 2psi of each other.
If values are not within specification, call Hypertherm technical service for PCB2 calibration procedure.
