1.02 Important Safety Precautions
WARNING
OPERATION AND MAINTENANCE OF PLASMA ARC
EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS
TO YOUR HEALTH.
Plasma arc cutting produces intense electric and magnet
ic emissions that may interfere with the proper function
of cardiac pacemakers, hearing aids, or other electronic
health equipment. Persons who work near plasma arc
cutting applications should consult their medical health
professional and the manufacturer of the health equipment to determine whether a hazard exists.
To prevent possible injury, read, understand and follow
all warnings, safety precautions and instructions before
using the equipment. Call 1-603-298-5711 or your local
distributor if you have any questions.
GASES AND FUMES
Gases and fumes produced during the plasma cutting process can be
dangerous and hazardous to your health.
• Keep all fumes and gases from the breathing area. Keep your
head out of the welding fume plume.
• Use an air-supplied respirator if ventilation is not adequate to
remove all fumes and gases.
• The kinds of fumes and gases from the plasma arc depend on
the kind of metal being used, coatings on the metal, and the
different processes. You must be very careful when cutting
-
Electric Shock can injure or kill. The plasma arc process uses and
produces high voltage electrical energy. This electric energy can cause
severe or fatal shock to the operator or others in the workplace.
Fire and explosion can be caused by hot slag, sparks, or the plasma
arc.
ELECTRIC SHOCK
• Never touch any parts that are electrically “live” or “hot.”
• Wear dry gloves and clothing. Insulate yourself from the work
piece or other parts of the welding circuit.
• Repair or replace all worn or damaged parts.
• Extra care must be taken when the workplace is moist or
damp.
• Install and maintain equipment according to NEC code, refer to
item 9 in Subsection 1.03, Publications.
• Disconnect power source before performing any service or
repairs.
• Read and follow all the instructions in the Operating Manual.
FIRE AND EXPLOSION
• Be sure there is no combustible or flammable material in the
workplace. Any material that cannot be removed must be
protected.
• Ventilate all flammable or explosive vapors from the work
place.
• Do not cut or weld on containers that may have held combus
tibles.
• Provide a fire watch when working in an area where fire hazards
may exist.

• Hydrogen gas may be formed and trapped under aluminum
workpieces when they are cut underwater or while using a water
table. DO NOT cut aluminum alloys underwater or on a water
table unless the hydrogen gas can be eliminated or dissipated.
Trapped hydrogen gas that is ignited will cause an explosion.
NOISE
Noise can cause permanent hearing loss. Plasma arc processes can
cause noise levels to exceed safe limits. You must protect your ears
from loud noise to prevent permanent loss of hearing.
• To protect your hearing from loud noise, wear protective ear
plugs and/or ear muffs. Protect others in the workplace.
• Noise levels should be measured to be sure the decibels (sound)
do not exceed safe levels.
• For information on how to test for noise, see item 1 in Subsec
tion 1.03, Publications, in this manual.
PLASMA ARC RAYS
Plasma Arc Rays can injure your eyes and burn your skin. The plasma
arc process produces very bright ultra violet and infrared light. These
arc rays will damage your eyes and burn your skin if you are not
properly protected.
• To protect your eyes, always wear a welding helmet or shield.
Also always wear safety glasses with side shields, goggles or
other protective eye wear.
• Wear welding gloves and suitable clothing to protect your skin
from the arc rays and sparks.
• Keep helmet and safety glasses in good condition. Replace
lenses when cracked, chipped or dirty.
• Protect others in the work area from the arc rays. Use protective
booths, screens or shields.
• Use the shade of lens as suggested in the following per ANSI/
ASC Z49.1:
Minimum Protective Suggested
Arc Current Shade No. Shade No.
Less Than 300* 8 9
300 - 400* 9 12

*These values apply where the actual arc is clearly
-
seen. Experience has shown that lighter filters may
be used when the arc is hidden by the workpiece.
LEAD WARNING
This product contains chemicals, including lead, or otherwise produces
chemicals known to the State of California to cause cancer, birth defects
and other reproductive harm. Wash hands after handling. (California

2T.03 Introduction to Plasma
A. Plasma Gas Flow
Plasma is a gas which has been heated to an extremely
high temperature and ionized so that it becomes electri
cally conductive. The plasma arc cutting and gouging
processes use this plasma to transfer an electrical arc
to the workpiece. The metal to be cut or removed is
melted by the heat of the arc and then blown away.
While the goal of plasma arc cutting is separation of
the material, plasma arc gouging is used to remove
metals to a controlled depth and width.
In a Plasma Cutting Torch a cool gas enters Zone B,
where a arc between the electrode and the torch tip
heats and ionizes the gas. The main cutting arc then
transfers to the workpiece through the column of
plasma gas in Zone C.
By forcing the plasma gas and electric arc through a
small orifice, the torch delivers a high concentration
of heat to a small area. The stiff, constricted plasma
arc is shown in Zone C. Direct current (DC) straight
polarity is used for plasma cutting, as shown in the
illustration.
Zone A channels a secondary gas that cools the torch.
This gas also assists the high velocity plasma gas in
blowing the molten metal out of the cut allowing for a
fast, slag - free cut.
B. Gas Distribution
The single gas used is internally split into plasma and
secondary gases.
-
The plasma gas flows into the torch through the
negative lead, through the starter cartridge, around
the electrode, and out through the tip orifice.
The secondary gas flows down around the outside
of the torch starter cartridge, and out between the tip
and shield cup around the plasma arc.
C. Pilot Arc
When the torch is started a pilot arc is established
between the electrode and cutting tip. This pilot
arc creates a path for the main arc to transfer to the
work.
D. Main Cutting Arc
DC power is also used for the main cutting arc. The
negative output is connected to the torch electrode
through the torch lead. The positive output is con
nected to the workpiece via the work cable and to the
torch through a pilot wire.
E. Parts - In - Place (PIP)
The torch includes a 'Parts - In - Place' (PIP) circuit.
When the shield cup is properly installed, it closes
a switch. The torch will not operate if this switch is
open.

When the shield cup is properly installed, there
is a slight gap between the shield cup and the
torch handle. Gas vents through this gap as
part of normal operation. Do not attempt to
force the shield cup to close this gap. Forcing
the shield cup against the torch head or torch
handle can damage components.
E. For a consistent standoff height from the
workpiece, install the standoff guide by sliding
it onto the torch shield cup. Install the guide
with the legs at the sides of the shield cup
body to maintain good visibility of the cutting
arc. During operation, position the legs of the
standoff guide against the workpiece.
C. Keep the torch in contact with the workpiece
during the cutting cycle.
D. Hold the torch away from your body.
E. Slide the trigger release toward the back of the
torch handle while simultaneously squeezing
the trigger. The arc will start.

4.04 Cut Quality
NOTE
Cut quality depends heavily on setup and
parameters such as torch standoff, alignment
with the workpiece, cutting speed, gas pres
sures, and operator ability.
cutskill 35A
Nitride Build - Up
Nitride deposits can be left on the surface of the cut
when nitrogen is present in the plasma gas stream.
These buildups may create difficulties if the material
is to be welded after the cutting process.
Bevel Angle
The angle between the surface of the cut edge and
a plane perpendicular to the surface of the plate. A
perfectly perpendicular cut would result in a 0° bevel
angle.
Top - Edge Rounding
Rounding on the top edge of a cut due to wearing
-
from the initial contact of the plasma arc on the
workpiece.
Refer to appendix pages for additional infor
-
mation as related to the power supply used.
Cut quality requirements differ depending on application.
For instance, nitride build - up and bevel angle may be
major factors when the surface will be welded after cut
ting. Dross - free cutting is important when finish cut
quality is desired to avoid a secondary cleaning operation.
The following cut quality characteristics are illustrated in
the following figure:
Bottom Dross Buildup
Molten material which is not blown out of the cut area
and resolidifies on the plate. Excessive dross may
require secondary cleanup operations after cutting.
-
Kerf Width
The width of the cut (or the width of material removed
during the cut).
Top Spatter (Dross)
Top spatter or dross on the top of the cut caused by
slow travel speed, excess cutting height, or cutting
tip whose orifice has become elongated.
Cut Quality Characteristics
Cut Surface
The desired or specified condition (smooth or rough)
of the face of the cut.

4.05 General Cutting Information
WARNING
Disconnect primary power at the source be
fore disassembling the power supply, torch,
or torch leads.
Frequently review the Important Safety Pre
cautions at the front of this manual. Be sure
the operator is equipped with proper gloves,
clothing, eye and ear protection. Make sure
no part of the operator’s body comes into
contact with the workpiece while the torch is
activated.\
CAUTION
Sparks from the cutting process can cause
damage to coated, painted, and other surfaces
such as glass, plastic and metal.
NOTE
Handle torch leads with care and protect them
from damage.
Torch Standoff
Improper standoff (the distance between the torch tip
and workpiece) can adversely affect tip life as well as
shield cup life. Standoff may also significantly affect
the bevel angle. Reducing standoff will generally
result in a more square cut.
Edge Starting
-
-
Side Characteristics Of Cut
To make a square - edged cut along an inside diameter
of a circle, the torch should move counterclockwise
around the circle. To keep the square edge along
an outside diameter cut, the torch should travel in a
clockwise direction.
Dross
When dross is present on carbon steel, it is com
monly referred to as either “high speed, slow speed,
or top dross”. Dross present on top of the plate is
normally caused by too great a torch to plate distance.
"Top dross" is normally very easy to remove and can
often be wiped off with a welding glove. "Slow speed
dross" is normally present on the bottom edge of the
plate. It can vary from a light to heavy bead, but does
not adhere tightly to the cut edge, and can be easily
scraped off. "High speed dross" usually forms a narrow bead along the bottom of the cut edge and is very
difficult to remove. When cutting a troublesome steel,
it is sometimes useful to reduce the cutting speed to
produce "slow speed dross". Any resultant cleanup
can be accomplished by scraping, not grinding.
-
For edge starts, hold the torch perpendicular to the
workpiece with the front of the tip near (not touching)
the edge of the workpiece at the point where the cut
is to start. When starting at the edge of the plate, do
not pause at the edge and force the arc to "reach" for
the edge of the metal. Establish the cutting arc as
quickly as possible.
Direction of Cut
In the torches, the plasma gas stream swirls as it
leaves the torch to maintain a smooth column of
gas. This swirl effect results in one side of a cut
being more square than the other. Viewed along the
direction of travel, the right side of the cut is more
square than the left.
