SECTION 1 SAFETY PRECAUTIONS
1.0 Safety Precautions
1.1 Safety - English
WARNING: These Safety Precautions are
for your protection. They summarize pre-
cautionary information from the references
listed in Additional Safety Information sec-
tion. Before performing any installation or operating
procedures, be sure to read and follow the safety precau-
tions listed below as well as all other manuals, material
safety data sheets, labels, etc. Failure to observe Safety
Precautions can result in injury or death.
PROTECT YOURSELF AND OTHERS --
Some welding, cutting, and gouging
processes are noisy and require ear
protection. The arc, like the sun, emits
ultraviolet (UV) and other radiation
and can injure skin and eyes. Hot metal can cause
burns. Training in the proper use of the processes
and equipment is essential to prevent accidents.
Therefore:
1. Always wear safety glasses with side shields in any
work area, even if welding helmets, face shields, and
goggles are also required.
2. Use a face shield tted with the correct lter and
cover plates to protect your eyes, face, neck, and
ears from sparks and rays of the arc when operating
or observing operations. Warn bystanders not to
watch the arc and not to expose themselves to the
rays of the electric-arc or hot metal.
3. Wear ameproof gauntlet type gloves, heavy long-
sleeve shirt, cuess trousers, high-topped shoes,
and a welding helmet or cap for hair protection, to
protect against arc rays and hot sparks or hot metal.
A ameproof apron may also be desirable as protec-
tion against radiated heat and sparks.
4. Hot sparks or metal can lodge in rolled up sleeves,
trouser cus, or pockets. Sleeves and collars should
be kept buttoned, and open pockets eliminated from
the front of clothing.
5. Protect other personnel from arc rays and hot
sparks with a suitable non-ammable partition or
curtains.
6. Use goggles over safety glasses when chipping slag
or grinding. Chipped slag may be hot and can y far.
Bystanders should also wear goggles over safety
glasses.
FIRES AND EXPLOSIONS -- Heat from
ames and arcs can start res. Hot
slag or sparks can also cause res and
explosions. Therefore:
1. Remove all combustible materials well away from
the work area or cover the materials with a protec-
tive non-ammable covering. Combustible materials
include wood, cloth, sawdust, liquid and gas fuels,
solvents, paints and coatings, paper, etc.
2. Hot sparks or hot metal can fall through cracks or
crevices in oors or wall openings and cause a hid-
den smoldering re or res on the oor below. Make
certain that such openings are protected from hot
sparks and metal.
3. Do not weld, cut or perform other hot work until the
workpiece has been completely cleaned so that there
are no substances on the workpiece which might
produce ammable or toxic vapors. Do not do hot
work on closed containers. They may explode.
4. Have re extinguishing equipment handy for instant
use, such as a garden hose, water pail, sand bucket,
or portable re extinguisher. Be sure you are trained
in its use.
5. Do not use equipment beyond its ratings. For ex-
ample, overloaded welding cable can overheat and
create a re hazard.
6. After completing operations, inspect the work area
to make certain there are no hot sparks or hot metal
which could cause a later re. Use re watchers when
necessary.
7. For additional information, refer to NFPA Standard
51B, "Fire Prevention in Use of Cutting and Welding
Processes", available from the National Fire Protec-
tion Association, Batterymarch Park, Quincy, MA
02269.
ELECTRICAL SHOCK -- Contact with
live electrical parts and ground can
cause severe injury or death. DO NOT
use AC welding current in damp areas,
if movement is conned, or if there is
danger of falling.
6
SECTION 1 SAFETY PRECAUTIONS
1. Be sure the power source frame (chassis) is con-
nected to the ground system of the input power.
2. Connect the workpiece to a good electrical
ground.
3. Connect the work cable to the workpiece. A poor
or missing connection can expose you or others
to a fatal shock.
4. Use well-maintained equipment. Replace worn or
damaged cables.
5. Keep everything dry, including clothing, work
area, cables, torch/electrode holder, and power
source.
6. Make sure that all parts of your body are insulated
from work and from ground.
7. Do not stand directly on metal or the earth while
working in tight quarters or a damp area; stand
on dry boards or an insulating platform and wear
rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the
power.
9. Turn o the power before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 (listed on
next page) for specic grounding recommenda-
tions. Do not mistake the work lead for a ground
cable.
ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric cur-
rent owing through any conduc-
tor causes localized Electric and
Magnetic Fields (EMF). Welding and
cutting current creates EMF around welding cables
and welding machines. Therefore:
1. Welders having pacemakers should consult their
physician before welding. EMF may interfere with
some pacemakers.
2. Exposure to EMF may have other health eects which
are unknown.
3. Welders should use the following procedures to
minimize exposure to EMF:
A. Route the electrode and work cables together.
Secure them with tape when possible.
B. Never coil the torch or work cable around your
body.
C. Do not place your body between the torch and
work cables. Route cables on the same side of
your body.
D. Connect the work cable to the workpiece as close
as possible to the area being welded.
E. Keep welding power source and cables as far
away from your body as possible.
FUMES AND GASES -- Fumes and
gases, can cause discomfort or harm,
particularly in conned spaces. Do
not breathe fumes and gases. Shield-
ing gases can cause asphyxiation.
Therefore:
1. Always provide adequate ventilation in the work area
by natural or mechanical means. Do not weld, cut, or
gouge on materials such as galvanized steel, stain-
less steel, copper, zinc, lead, beryllium, or cadmium
unless positive mechanical ventilation is provided.
Do not breathe fumes from these materials.
2. Do not operate near degreasing and spraying opera-
tions. The heat or arc rays can react with chlorinated
hydrocarbon vapors to form phosgene, a highly
toxic gas, and other irritant gases.
3. If you develop momentary eye, nose, or throat ir-
ritation while operating, this is an indication that
ventilation is not adequate. Stop work and take
necessary steps to improve ventilation in the work
area. Do not continue to operate if physical discom-
fort persists.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below)
for specic ventilation recommendations.

5. WARNING: This product, when used for welding
or cutting, produces fumes or gases
which contain chemicals known to
the State of California to cause birth
defects and, in some cases, cancer.
(California Health & Safety Code
§25249.5 et seq.)
CYLINDER HANDLING -- Cylinders,
if mishandled, can rupture and vio-
lently release gas. Sudden rupture
of cylinder, valve, or relief device can
injure or kill. Therefore:
1. Use the proper gas for the process and use the
proper pressure reducing regulator designed to
operate from the compressed gas cylinder. Do not
use adaptors. Maintain hoses and ttings in good
condition. Follow manufacturer's operating instruc-
tions for mounting regulator to a compressed gas
cylinder.
2. Always secure cylinders in an upright position by
chain or strap to suitable hand trucks, undercar-
riages, benches, walls, post, or racks. Never secure
cylinders to work tables or xtures where they may
become part of an electrical circuit.
3. When not in use, keep cylinder valves closed. Have
valve protection cap in place if regulator is not con-
nected. Secure and move cylinders by using suitable
hand trucks. Avoid rough handling of cylinders.
4. Locate cylinders away from heat, sparks, and ames.
Never strike an arc on a cylinder.
5. For additional information, refer to CGA Standard P-1,
"Precautions for Safe Handling of Compressed Gases
in Cylinders", which is available from Compressed
Gas Association, 1235 Jeerson Davis Highway,
Arlington, VA 22202.
EQUIPMENT MAINTENANCE -- Faulty or
improperly maintained equipment can
cause injury or death. Therefore:
1. Always have qualied personnel perform the instal-
lation, troubleshooting, and maintenance work.
Do not perform any electrical work unless you are
qualied to perform such work.
2. Before performing any maintenance work inside a
power source, disconnect the power source from
the incoming electrical power.
3. Maintain cables, grounding wire, connections, power
cord, and power supply in safe working order. Do
not operate any equipment in faulty condition.
4. Do not abuse any equipment or accessories. Keep
equipment away from heat sources such as furnaces,
wet conditions such as water puddles, oil or grease,
corrosive atmospheres and inclement weather.

3.0 General
3.1 Scope
The purpose of this manual is to provide the operator with all the information re-
quired to install and operate the Plumbing Box & Plasma Control Interface. Technical
reference material is also provided to assist in troubleshooting.
Specications: PCC-14 Plumbing Box
Plasma and Start Gases:
The PCC-14 may be used with O2, N2, Air or H-35 (35% H2/65% Ar) at a maximum input pressure of 125 psig (8.6 bar).
It is recommended, but not required, that N2 be used as the start gas when using H-35. The ow rate of gas will depend on
the pressure set, the torch connected to the plumbing box, and the parts installed in the torch. Without a torch attached,
the maximum ow rate for these gases at 100 psig (6.9 bar) is about 1000 scfh (28.3 cu-m/h). The minimum acceptable
pressure for the start gas is 15 psig (1.0 bar); for the cut gas it is 24 psig (1.7 bar). Below these pressures the pressure switches
may not be satised.
Shield Gases:
The PCC-14 may be used with Air, N2, Ar, or CO2. The maximum pressure is for N2, Ar, Air or CO2 is 125 psig (8.6 bar). This
will result in a ow of 250 scfh (7.1 cu-m/h) N2. See Graph 3-1. There is no pressure interlock on the shield gas.
Coolant:
The PCC-14 is designed for use with plasma torch coolant (ESAB P/N’s 156F05 or 0558004297). Maximum design pressure
is 200 psig (13.8 bar). Flow rates depend on the torch but typically vary from 0.9 to 2 gpm (4.1 to 9.1 l/m).
22
SECTION 3 PCC14 PLUMBING BOX DESCRIPTION / INSTALLATION
Gas Purging:
When switching between H-35 and an oxidizing gas (air or oxygen) it is recommended that the following procedure be
followed:
1. Turn o the gas.
2. Put the system into plasma gas test until line pressure is exhausted. If the start gas is being switched to or from
H-35, switch to start gas test until that line is exhausted as well.
3. Disconnect the old gas and connect a relatively inert gas such as nitrogen, argon, carbon dioxide, C-25, etc. Set the
pressure to 50 psig (3.5 bar) and purge each aected line for 60 seconds.
4. Then shut o the gas and exhaust each line per Step 2.
5. Connect the gas to be used. Set the pressure to recommended values for the cutting condition to be used, and
purge each aected line for 15 seconds per 25 ft. (7.6 m) of line.
Flashback arrestors are required to prevent re from propagating
back to the gas supply through lines carrying oxygen or fuel gases.
Use AWG 2/0 power cable to carry electrode current from the power
source to the PCC-14. See section 9.0 for additional cables.
Avoid using the same supply lines for both oxygen and air if oil may
be mixed with the air. Oil in the presence of 100% oxygen can be
highly ammable.
Failure to observe above cautions may result in personal injury and /
or damage to the equipment.
CAUTION
Note:
The expected life of the internal exible hoses is 10 years. Replace them earlier if cracking or brittleness is noted.
Note:
When marking, ensure the start gas line is pressurized to avoid pressure switch errors.
Marking option
With the optional Marking Module installed, the PCC-14 will allow you to switch the cut gas to Argon for plate marking. With
the Marking Module installed, Argon gas input to the Marking Module is 125 psig (8.6 Bar).
