Adjust H35 Gas Flow
1. Set S2 on the gas console to Test Preflow. Verify that the argon-
hydrogen supply regulator reads 120 psi (8.2 bar).
2. Look at the flowmeter (FM1) on the argon-hydrogen manifold and set
the Preflow plasma gas flow rate % by referring to the Cut Charts and
turning the argon-hydrogen flowmeter adjust knob (MV1).
3. Look at the shield gas pressure gauge (PG3) on the gas console, and
set to the Cut Chart specifications by turning the shield gas adjust
knob (MV4).
4. Set S2 to Run after the test preflow rate has been set.
The system is now ready to run.
