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.

instructions could result in death or serious injury.
Read and understand all safety warning labels on machine.
Refer to operator’s manual for additional safety information.
WARNING
!
Improperly Installed Equipment Can Cause Injury Or Death.
Follow these guidelines while installing machine:
· Do not connect a cylinder directly to machine inlet.
An appropriate cylinder regulator must be installed on a fuel gas cylinder to reduce pressure to a reasonable inlet supply pressure. Machine regulator is then used to obtain pressure required by torches.
· Contact your ESAB representative before
installation. He can suggest certain precautions regarding piping installation and machine lifting, etc. to ensure maximum security.
· Never attempt any machine modifications or
apparatus additions without first consulting a qualified ESAB representative.
· Observe machine clearance requirements for
proper operation and personnel safety.
· Always have qualified personnel perform
installation, troubleshooting and maintenance of this equipment.

WARNING
!
Fumes and gases generated by the plasma cutting process can be hazardous to your health.
· Do NOT breathe fumes.
· Do not operate plasma torch without fume removal
system operating properly.
· Use additional ventilation to remove fumes if necessary.
· Use approved respirator if ventilation is not
adequate.
·
Provide positive mechanical ventilation when cutting galvanized steel, stainless steel, copper, zinc, beryllium, or cadmium. Do not breathe these fumes.
·
Do not operate near degreasing and spraying operations. Heat or arc rays can react with chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas and other irritant gases.

· Replace glasses/goggles when lenses are pitted or broken
· Warn others in area not to look directly at the arc unless wearing appropriate safety glasses.
· Prepare cutting area to reduce reflection and transmission of ultraviolet light.
§ Paint walls and other surfaces with dark colors to reduce reflections.
§ Install protective screens or curtains to
reduce ultraviolet transmission.
WARNING
!
Ruptured Gas Cylinders Can Kill
Mishandling gas cylinders can rupture and violently release gas.
· Avoid rough handling of cylinders.
· Keep cylinder valves closed when not in use.
· Maintain hoses and fittings in good condition.
· Always secure cylinders in an upright position by
chain or strap to a suitable stable object not part of an electrical circuit.
· Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.
· Use approved pressure reducing regulator for the specific gas.
· Refer to CGA Standard P-1, “Precautions for Safe Handling of Compressed Gases in Cylinders”, available from Compressed Gas Association.

SECTION 1 SAFETY
WARNING
!
Heat, spatter, and sparks cause fire and burns.
· Do not cut near combustible material.
· Do not have on your person any combustibles (e.g.
butane lighter).

3.1 General
NOTICE
Proper installation can contribute materially to the 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 150 psig (10.4 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 (P/N 56998133) are required
on the supply side for the IFC 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.
Restricting Air Flow Will Cause Over-Heating
CAUTION
!

4.2 Cut Quality
4.2.1 Introduction
NOTICE
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.
Before attempting ANY corrections, check cutting variables with the factory recommended settings/consumable part numbers listed in Process Data.

4.2.6 Dimensional Accuracy
NOTICE
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.
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.
NOTICE
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
4.3.1 Introduction
All gases are not suitable for all situations. Certain gases assist in cutting specific materials and thickness.

nitrogen can effectively improve dross formation on thin material of 26 GA to 10 GA carbon steel. Also, an oxygen only shield may provide acceptable results on thinner materials.

Oxygen
Nitrogen
Cutting carbon steel with oxygen results in an exothermic reaction. This chemical reaction causes the carbon in the material to burn similar to when oxy­fuel cutting. This plus the electrical energy uses lower amperage levels without sacrificing cut speed.

Nitrogen/Methane
Because methane is a fuel gas, flow/pressure rates can affect the cut angle. High flow/pressure results in a negative cut angle, low flow/pressure results in a positive cut angle. Nitrogen to methane ratio is 10 to 14 parts N2/ 1 part CH4. The lip formed on the cut face bottom is severe, making Nitrogen/Methane shield gas combination unsuitable for some finished part applications.
