At ambient temperatures below –55 C
(235
F),
readjustment
of
pressure regulator may be necessary
(see Section 3-12).
Use only clean, dry air with 90 to 150 psi
(620 to 1035 kPa) pressure. Prevent
moisture from entering air supply at
extreme cold temperatures.
The cutting speed curve shows the
recommended maximum cutting
speed capabilities of the power
source and torch for mild steel of
various thickness.
The best cut quality is achieved by
cutting near the chart line. Cutting
below the line (too slow) will result
in excess dross. Cutting above the
line (too fast) will cause blowback
and lack of penetration.
