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.

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.

SECTION 1 SAFETY PRECAUTIONS

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

SECTION 3 PCC14 PLUMBING BOX DESCRIPTION / INSTALLATION

The PCC-14 Plumbing Box is a Plasmarc Cutting Control used to connect the PT-36R

Plasma Torch to a remotely located EPP-201 or EPP-360 power supply system. The

PCC-14 includes high frequency starting circuits to eliminate starting problems

with long torches and to minimize high frequency interference with other customer

systems.

OR REPAIRS ON THIS EQUIPMENT.

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

Weight: 41lbs. (18.6 kg)

Plasma and Start Gases:

The PCC-14 may be used with O2, N2, Air, or Ar/H2 with a maximum input pressure of 110 psig (7.6 bar). ***These are

maximum input pressures and do not reect actual cutting pressures.***

It is recommended, but not required, that N2 be used as the start gas when using Ar/H2. The ow rate of gas will de-

pend 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 19 psig (1.3 bar); for the plasma 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 110 psig (7.6 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).

SECTION 3 PCC14 PLUMBING BOX DESCRIPTION / INSTALLATION

Gas Purging:

When switching between Ar/H2 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 Ar/

H2, 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).
