3. Apply thread sealer (see NOTE) to the other elbow of the Y-
Hose Assembly.
NOTE
Do Not use teflon tape as a thread sealer as small
particles of the tape may break off and cause the
small gas passage to be blocked in the torch.
4. Connect the elbow fitting to the SECONDARY AIR
1/4 NPT gas fitting.
5. Connect the supply line from the air supply source to
the Y-hose assembly. The supply hose must be
3/8 inch (10 mm) minimum inside diameter to pro-
vide adequate air flow.
B. Using High-Pressure Gas Cylinders
NOTES
Refer to the regulator manufacturer’s specifica-
tions for installation and maintenance procedures.
Refer to Section 6.05, System Options and Acces-
sories, or a listing of available high-pressure regu-
lators.
Do not use an air line filter with high pressure gas
cylinders.
Examine the cylinder valves to be sure they are clean and
free of oil, grease or any foreign material. Momentarily
open each cylinder valve to blow out any dust which may
be present.
WARNING
Do not stand in front of the valve outlet when open-
ing.
Each cylinder must be equipped with an adjustable high-
pressure regulator capable of pressures up to 125 psi (8.6
bar) maximum and flows of up to 700 scfh (328 lpm) for
cutting or gouging.
CAUTION
Maximum input pressure to the internal regula-
tor on the Power Supply must not exceed 125 psi
(8.6 bar).
