10. Set
S2
on the gas console to
Test Preflow.
Verify that the plasma gas
pressure gauges (
PG1, PG2
) on the gas console both read 120 psi
(8.2 bar).
11. Look at the oxygen (
FM2
) and/or nitrogen-air (
FM1
) flowmeters on the
gas console and set the
Preflow
plasma gas flow rate % by referring to
the
Cut Charts
and turning the oxygen (
MV3
) and/or nitrogen- air (
MV2
)
preflow flowmeter adjust knobs.
12. 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
(
