NOTES
Refer to the manufacturer’s specifications for in-
stallation and maintenance procedures. Refer to
sales literature for a listing of available high-pres-
sure regulators and accessories.
Do not use an air line filter with high pressure regu-
lators.
1. Examine the cylinder valves to be sure they are clean
and free of oil, grease or any foreign material. Mo-
mentarily open each cylinder valve to blow out any
dust which may be present.
WARNING
Do not stand in front of valve outlet when open-
ing.
2. Each cylinder must be equipped with an adjustable
high-pressure regulator capable of outlet pressures up
to 100 psi (6.9 bar) maximum and flows of up to 400
scfh (188.7 lpm).
CAUTION
Pressure should be set at 100 psi (6.9 bar) at the
high pressure gas cylinder regulator.
3. Connect the SECONDARY gas supply to the rear of
the Power Supply per the following:
a. Remove the factory installed plug fitting from
the end of the T-Fitting on the "Y" Hose As-
sembly.
b. Disconnect the Secondary Hose from the T-Fit-
ting and install the plug removed above into
the hole. This will prevent lost of the plasma
gas when all connections are made.
c. Remove the Secondary Hose from the Inert-B
Fitting at the Secondary air regulator of the
Power Supply.
d. Connect the customer supplied gas cylinder
supply hose from the secondary gas source to
the Inert-B Fitting on the SECONDARY air
regulator of the Power Supply.
4. Connect the PLASMA shop air supply to the rear of
the Power Supply per the following:
a. Locate the 1/4 NPT to #4 (6 mm) barbed hose
fitting shipped inside the Torch Spare Parts Kit.
b. Install the supplied barbed fitting into the in-
put of the T-Fitting.
