GAS INPUT CONNECTIONS
Supply the PYTHON with clean compressed air or
nitrogen.
•
Supply pressure must be between 80 psi
and 120 psi.
• Pressure gage, located on the front of the
machine, should be set to approximately 70
PSI for a 25 ft. torch and 75 PSI for a 50 ft.
torch while gas is flowing (purging or cutting).
•
Flow rate should be approximately 8.0
cfm (227 I/min.).
NOTE:
Oil in the air supply to the PYTHON can
cause severe problems. Use only a clean air
supply.
•
Connect the gas supply to the PYTHON regu-
lator.
•
Compressed gas should be supplied to the fit-
ting connection mounted on the filter at the
rear of the machine. If necessary, this fitting
can be removed allowing plumbing access
through the 1/4” NPT input port on the filter
body.
• If compressed air is being used, it is highly recom-
mended that an inline prefilter be installed in the air
supply line ahead of the air connection to the PRO-
CUT’S coalescing filter. While the coalescing filter is
used to remove small amounts of oil and water
aerosol particles from the air supply line, the prefilter
can be used to remove larger particulates before
they reach the coalescing filter element.This will
prolong the life of the coalescing filter element by up
to six times what it would be without the prefilter,
and in turn, prolong the life of the PRO-CUT torch
and consumables as well.
• A standard nominal 5 micron inline prefilter is rec-
ommended; however, for optimum performance,
select a prefilter with a 3 micron absoluterating.If
these filter ratings are unavailable, anything with a
rating less than, or equal to, 20 micron would be
acceptable to use. Inline filter elements will general-
ly filter the air with little restriction to the airflow until
the element is about 75% contaminated. After this
point, there will bea noticeable pressure drop in the
line. Filter elements should be replaced when a
pressure drop of 8-10 psi is indicated; however, for
optimum performance of the PRO-CUT, the filter
element should be replaced at or before the pres-
sure drop reaches 8 psi. Be sure to select a prefilter
that will accommodate the necessary flow rating for
the PRO-CUT as specified in the Installation sec-
tion of this instruction manual under the Gas Input
Connections heading.
• While it is recommended that an inline prefilter be
placed ahead of each PRO-CUT, that may be in
stalled in a shared air supply line, one large in line
prefilter may instead be used to accommodate sev-
eral PRO-CUT’s simultaneously. If a shared pre is
desired, it must be rated to provide the necessary
flow rate, as specified, to ensure proper operation of
each of the PRO-CUT’s sharing a connection.
NOTE:
When using nitrogen gas from a cylinder, the
cylinder must have a pressure regulator.
•
Maximum psi from the nitrogen gas cylinder to
the PYTHON regulator should never exceed
120 psi.
•
Install a hose between the nitrogen gas
cylinder regulator and the PYTHON
gas inlet.
CYLINDER could explode if damaged.
• Keep cylinder upright and
chained to a fixed support.
• Keep cylinder away from areas
where it could be damaged.
• Never lift machine with cylinder
attached.
• Never allow the cutting torch to
touch the cylinder.
• Keep cylinder away from live electrical parts.
• Maximum inlet pressure 120 psi.

OUTPUT CONNECTIONS
Torch Connection
The PYTHON is sent from the factory with a PCT 80
cutting torch. Additional cutting torches can be
ordered from the K1571 series. Hand-held and mech-
anized torches come with 25' or 50’ cables.
All torches are connected to the PYTHON with a quick
connect on the case front for easy change over. This
feature is excellent for changing between a hand cut-
ting torch and a mechanized torch.
For more information on the torch and its components,
refer to the PCT80 Operator’s Manual (IM588 latest
version).
