a. Air Supply — Aminimum of 290 cfh ofair is required
for the cutting/cooling gas. Clean, dry air at a pres-
sure between 90 and 150 psi should be supplied to the
inlet of the air filter-regulator supplied with each
PCM-70/PT-17A Packages.
2. Using PT-121 Torch
a. Nitrogen or H-35 Gas Supply — Nitrogen is most
commonly used for plasma gas on the PT-121 torch.
A single cylinder can be used for both plasma and
cooling by use of the “Y” connector on outlet of
regulator.
NOTE: When using CO2 as a cooling gas, at least 4 cylinders
should be manifolded or a high capacity CO2 heater
may be employed to prevent “freeze-ups” or dry-ice
formation at the regulator.
If using H-35 for plasma gas, air and CO2 produce the
least dross and are recommended for low carbon and
stainless steels. Nitrogen produces the smoothest
face on aluminum but air or CO? can also be used.
c. Mechanized Torch (PT-17AM or PT-121M)
Mounting and Travel Carriage — A Torch Rigging
Assembly, P/N 995984 (see Form 14-390), is available
for mounting the PT-17AM or PT-121M torch on a
CM-79 or CM-37 travel carriage. If using a CM-79, an
adaptor assembly (490769) is also required.
H-35 (35% Hydrogen; 65 Argon) gas mixture is an
excellent plasma gas for cutting aluminum or thick
steel. It is usually considered over nitrogen in
mechanized or production cutting due to its ability to
cut thicker materials as well as cutting thick
materials with higher speeds. The H-35 also provides
longer consumable life with less fume emission.
These advantages often outweigh the greater ex-
pense of the mixture. If using the H-35, the following
will be required:
If using the PT-17AM or PT-121M with the CM-86
Shape Cutting Machine, an adaptor kit (P/N 600435)
will be required. This adaptor kit permits the torch
head to be in line with the rotor head of the cutting
machine.
R-77-75-350 Fuel Gas Regulator, P/N 998341
Fuel Gas Hose Assembly (12-1/2-ft.), P/N 19414 The PT-17AM or PT-121M can also fit any standard
L-TEC torch holder designed for torches with 1-3/8-
in. diam. barrel and 32-pitch rack on riggings of
larger cutting machines such as CM-50, CM-100, and
others. See your L-TEC representative for more
details.

b. Cooling Gas — If not using nitrogen for cooling, then
either a cylinder of CO2 or a suitable supply of air
(150 psig max.) will be required. (See Tables 4 and 5.)
