SECTION 1 SAFETY

1.1 Introduction

The process of cutting metals with plasma equipment
provides industry with a valuable and versatile tool.
ESAB cutting machines are designed to provide both
operation safety and efficiency. However, as with any
machine tool, sensible attention to operating
procedures, precautions, and safe practices is
necessary to achieve a full measure of usefulness.
Whether an individual is involved with operation,
servicing, or as an observer, compliance with
established precautions and safe practices must be
accomplished. Failure to observe certain precautions
could result in serious personnel injury or severe
equipment damage. The following precautions are
general guidelines applicable when working with
cutting machines. More explicit precautions pertaining
to the basic machine and accessories are found in the
instruction literature. For a wide scope of safety
information on the field of cutting and welding
apparatus, obtain and read the publications listed in
the Recommended References.

2.1 General

2.2 Scope

The Precision Plasmarc System consists of four
separate components. The power source, the
junction box, the flow control box, and the PT-24
torch. The power source provides power and
coolant to the PT-24 torch via the junction box.

The purpose of this manual is to provide the
operator with all the information required to install
and operate the Precision Plasmarc System.
Technical reference material is also provided to
assist in troubleshooting the cutting package.

SECTION 3 INSTALLATION

3.1 General

Proper installation can contribute materially to the

NOTICE

satisfactory and trouble-free operation of the Precision
Plasmarc System. It is suggested that each step in
this section be studied and carefully followed.

3.2 Equipment Required

3.3 Location

• Gas Supply and Hoses. Gas supply may be from

a bulk source or from a bank of manifold cylinders
and regulated to supply 125 psig (8.6 bar) to the
Flow Control (gas flowing).

• Work Lead. No. 4 AWG cable is recommended for

connecting workpiece to power source.

• Primary Input Cable.

• 25 micron gas filters (or better) are required on the

supply side for the EFC to function properly.

• Ventilation is necessary to provide proper cooling

of the power supply.

• Minimize dirt, dust and exposure to external heat

sources.

• Allow a minimum of two feet clearance around the

power supply for free air movement.

CAUTION

!

Do Not Restrict Air Flow

3.4 Primary Electrical Input Connections

Electric Shock Can Kill!

DANGER

!

Provide maximum protection against electrical
shock.

Before any connections are made inside the
machine, open the line (wall) disconnect switch
and unplug the power cord.

Input Power Configuration

WARNING

!

Machine must be properly configured for your
input power.

The machine is shipped from the factory
configured for 575 V, 60 Hz input.

Do NOT connect a power source of any other
voltage unless machine is reconfigured. Damage
to the machine will occur.

Input Power Connection At Wall

A line (wall) disconnect switch with fuses or circuit
breakers should be provided at the main power panel.

Connect the input power cable of the power source
directly to the disconnect switch or a proper plug and
receptacle may be purchased from a local electrical
supplier. (S ee table on the next page for
recommended input conductors and fuses )

main contactor. Tighten strain relief to ensure
input power cable is secured.

5. Connect input power cable ground wire to the
ground lug provided on the base of the power
source.

6. Connect three power leads of the input power
cable to the terminals located atop the main
contactor. Secure the leads by tightening each
screw.

7. Connect jumper power cables from the bottom of
the main contactor to the proper input voltage
marked on the auto transformer. The unit is
factory set for 575 V as shown to the left.

3.9 Replacement of EPROM in the Plasmarc Power Source Programmable Logic
Controller (PLC)

The Precision Plasmarc System may be shipped
configured for a manual flow control (Series “A”). If
so, the EPROM in the Programmable Logic
Controller must be replaced with an EFC EPROM.
This EFC EPROM is shipped with the power source.

Using the Wrong EPROM Could Result In

CAUTION

!

CAUTION

!

Damaged System Components

The Series “A” and the EFC EPROMs are
programmed with different software. The EFC
EPROM ignores the process gas pressure
switch inputs and does not include the
process gas purge required for the Series “A”.

Mishandling Can Damage Electronic
Components.

CAUTION

!

WARNING

!

Handle electronic components with care.

• Do not drop

• Do not bend pins

• Do not touch circuit components- handle

along edges when possible

Electronic Components Are Subject To
Electro-Static-Discharge (ESD) Damage

Integrated Circuit parts are sensitive to over
voltages. The damage may not be seen
immediately but show up as a premature
failure.

The EFC EPROM is shipped in an anti-static
bag. Store EPROM in this bag.

Wear a protective ground strap when handling
sensitive electronic components.

Electric shock Can Kill!

Unplug power cable from wall to power source
before any connections or adjustments are
made inside power source.

eliminate the need for special tools.

4. Remove the EPROM from the socket. THIS
DOES NOT REQUIRE A PULLER. Release the
clamp locking the EPROM in place, lift the
Series “A” EPROM from the socket.

5. Remove the EFC EPROM from the packaging.

6. Carefully align the EFC EPROM pins with the

4.2 Cut Quality

4.2.1 Introduction

Causes affecting cut quality are interdependent.
Changing one variable affects all others. Determining a
solution may be difficult. The following guide offers
possible solutions to different undesirable cutting
results. To begin select the most prominent condition:

§ 4.2.2 Cut Angle, negative or positive

§ 4.2. 3 Cut not flat, rounded or undercut

§ 4.2.4 Surface roughness

§ 4.2.5 Dross

Usually the recommended cutting parameters will give
optimal cut quality, occasionally conditions may vary
enough that slight adjustments will be required. If so:

• Make small incremental adjustments when

making corrections.

• Adjust Arc Voltage in 5 volt increments, up or

down as required.

• Adjust cutting speed 5% or less as required

until conditions improve.

NOTICE

4.2.2 Cut Angle

Before attempting ANY corrections, check cutting
variables with the factor y recommended
settings/consumable part numbers listed in
Process Data.

4.2.6 Dimensional Accuracy

Generally using the slowest possible speed (within
approved levels) will optimize part accuracy. Select
consumables to allow a lower arc voltage and slower
cutting speed.

NOTICE

NOTICE

Recommended cutting speed and arc voltage will
give optimal cutting performance in most cases.

Small incremental adjustments may be needed
due to material quality, material temperature and
specific alloy. The operator should remember
that all cutting variables are interdependent.
Changing one setting affects all others and cut
quality could deteriorate. Always start at the
recommended settings.

Before attempting ANY corrections, check
cutting variables with the factory recommended
settings/consumable part numbers listed in the
Process Data.

4.3 Influence of Gas Options on Cut Quality

All gases are not suitable for all situations. Certain
gases assist in cutting specific materials and

Cutting carbon steel with oxygen results in an exothermic reaction. This
chemical reaction causes the carbon in the material to burn similar to
