SAFETY
i
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN
AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.
Read and understand the following safety highlights. For additional safety information it is strongly recommended that you pur-
chase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box 351040,
Miami, Florida 33135 or CSA Standard W117.2.
BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
CUTTING SPARKS can
cause fire or explosion.
4.a..Remove fire hazards from the plasma cutting
or gouging area. If this is not possible, cover them
to prevent the cutting or gouging sparks from
starting a fire. Remember that welding sparks and
hot materials from plasma cutting or gouging can
easily go through small cracks and openings to adjacent
areas. Avoid cutting or gouging near hydraulic lines. Have a
fire extinguisher readily available.
4.b. Where compressed gases are to be used at the job site, spe-
cial precautions should be used to prevent hazardous situa-
tions. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the equip-
ment being used.
4.c. When not cutting or gouging, make certain no part of the elec-
trode circuit is touching the work or ground. Accidental con-
tact can cause overheating and create a fire hazard.
4.d. Do not cut or gouge tanks, drums or containers until the prop-
er steps have been taken to insure that such procedures will
not cause flammable or toxic vapors from substances inside.
They can cause an explosion even though they have been
“cleaned.” For information purchase “Recommended Safe
Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society
(see address above).
4.e. Vent hollow castings or containers before heating, cutting or
gouging. They may explode.
4.f. Do nor fuel engine driven equipment near area where plasma
cutting or gouging.
ARC RAYS can burn.
2.a. Use safety glasses and a shield with the prop-
er filter and cover plates to protect your eyes from
sparks and the rays of the arc when performing or
observing plasma arc cutting or gouging.
Glasses,headshield and filter lens should conform
to ANSI Z87. I standards.
2.b. Use suitable clothing including gloves made
from durable flame-resistant material to protect your skin and
that of your helpers from the arc rays.
2.c. Protect other nearby personnel with suitable non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
ELECTRIC SHOCK can
kill.
1.a. The electrode and work (or ground) circuits
are electrically “hot” when the power source is on.
Do not touch these “hot” parts with your bare skin
or wet clothing. Wear dry, hole-free gloves to
insulate hands.
1.b. When the power source is operating voltages in excess of
250 volts are produced. This creates the potential for serious
electrical shock - potentially even fatal.
1.c. Insulate yourself from work and ground using dry insulation.
When cutting or gouging in damp locations, on metal frame-
work such as floors, gratings or scaffolds and when in posi-
tions such as sitting or lying, make certain the insulation is
large enough to cover your full area of physical contact with
work and ground.
1.d. Always be sure the work cable makes a good electrical con-
nection with the metal being cut or gouged. The connection
should be as close as possible to the area being cut or
gouged.
1.e. Ground the work or metal to be cut or gouged to a good elec-
trical (earth) ground.
1.f. Maintain the plasma torch, cable and work clamp in good,
safe operating condition. Replace damaged insulation.
1.g. Never dip the torch in water for cooling or plasma cut or
gouge in or under water.
1.h. When working above floor level, protect yourself from a fall
should you get a shock.
1.i. Operate the pilot arc with caution. The pilot arc is capable of
burning the operator, others or even piercing safety clothing.
1.j. Also see Items 4c and 6.
WARNING
PLASMA CUTTING or GOUGING can be hazardous.
FUMES AND GASES
can be dangerous.
3.a. Plasma cutting or gouging may produce
fumes and gases hazardous to health. Avoid
breathing these fumes and gases.When cutting
or gouging, keep your head out of the fumes.
Use enough ventilation and/or exhaust at the arc
to keep fumes and gases away from the breathing zone.
When cutting or gouging on lead or cadmium plated
steel and other metals or coatings which produce highly
toxic fumes keep exposure as low as possible and
below Threshold Limit Values (TLV) using local exhaust
or mechanical ventilation. In confined spaces or in some
circumstances, outdoors, a respirator may be required.
Additional precautions are also required when welding
on galvanized steel.
3.b. Do not use plasma arc cutting or gouging in locations near
chlorinated hydrocarbon vapors coming from degreasing,
cleaning or spraying operations. The heat and rays of the arc
can react with solvent vapors to form phosgene, a highly
toxic gas, and other irritating products.
3.c. Gases used for plasma cutting and gouging can displace air
and cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
3.d. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your employ-
er’s safety practices.

Cylinders,”available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.
Apr. ‘93
ELECTRIC AND MAGNETIC FIELDS
may be dangerous
8.a. Electric current flowing through any con-
ductor causes localized Electric and Magnetic
Fields (EMF). Cutting or gouging current cre-
ates EMF fields around torch cables and cutting
machines.
8.b. EMF fields may interfere with some pacemakers, so opera-
tors having a pacemaker should consult their physician
before cutting or gouging.
8.c. Exposure to EMF fields during cutting or gouging may have
other health effects which are now not known.
8d. All operators should use the following procedures in order to
minimize exposure to EMF fields from the cutting or gouging
circuit:
8.d.1. Route the torch and work cables together - Secure
them with tape when possible.
8.d.2. Never coil the torch cable around your body.
8.d.3. Do not place your body between the torch and
work cables. If the torch cable is on your right side,
the work cable should also be on your right side.
8.d.4. Connect the work cable to the workpiece as close as
possible to the area being cut or gouged.
8.d.5. Do not work next to cutting power source.
4.g. Sparks and spatter are thrown from the plasma arc. Wear
safety glasses, ear protection and oil free protective garments
such as leather gloves, heavy shirt, cuffless trousers, high
shoes and a cap over your hair. Wear ear plugs when cutting
or gouging out of position or in confined places. Always wear
safety glasses with side shields when in a cutting or gouging
area.
4.h. Connect the work cable to the work as close to the cutting or
gouging area as practical. Work cables connected to the build-
ing framework or other locations away from the cutting or
gouging area increase the possibility of the current passing
through lifting chains, crane cables or other alternate circuits.
This can create fire hazards or overheat lifting chains or
cables until they fail.
PLASMA ARC can injure.
7.a. Keep your body away from nozzle and
plasma arc.
7.b. Operate the pilot arc with caution. The pilot arc is capable of
burning the operator, others or even piercing safety clothing.

PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suiv-
antes:
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien s’isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une grande
partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
d.Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
2. Dans le cas de travail au dessus du niveau du sol, se protéger
contre les chutes dans le cas ou on recoit un choc. Ne jamais
enrouler le câble-électrode autour de n’importe quelle partie
du corps.
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du ray-
onnement de l’arc et des projections quand on soude ou
quand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
l‘arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection libres
de l’huile, tels que les gants en cuir, chemise épaisse, pan-
talons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
8. S’assurer que la masse est connectée le plus prés possible
de la zone de travail qu’il est pratique de le faire. Si on place
la masse sur la charpente de la construction ou d’autres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de lev-
age, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant
d’opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de
l’électricité et aux recommendations du fabricant. Le dispositif
de montage ou la piece à souder doit être branché à une
bonne mise à la terre.
2. Autant que possible, I’installation et l’entretien du poste seront
effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la debranch-
er à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

SAFETY PRECAUTIONS
ELECTRIC SHOCK CAN KILL.
Only qualified personnel
should install this machine.
Turn the input power OFF
at the disconnect switch or
fuse box and discharge input
capacitors before working
inside the equipment.
Do not touch electrically hot parts.
Always connect the VIPER ground-
ing terminal (located on the side of the
Case Back Assembly) to a good electrical
earth ground.
Turn the VIPER Power Switch OFF
when connecting power cord to input
power.
___________________________________________
SELECT PROPER LOCATION
Place the VIPER where clean cool air can freely circu-
late in through the rear louvers and out through the
front/bottom opening. Dirt, dust or any foreign material
that can be drawn into the machine should be kept at
a minimum. Failure to observe these precautions can
result in excessive operating temperatures and nui-
sance shutdown of the machine.
A source of clean, dry air or nitrogen must be supplied
to the VIPER. Oil in the air is a severe problem and
must be avoided. The supply pressure must be
between 80 and 150 psi. The flow rate is approximate-
ly 6.0 cfm (170 l/min.). Failure to observe these pre-
cautions could result in excessive operating tempera-
tures or damage to the torch.
STACKING
The VIPER cannot be stacked.
LIFTING AND MOVING
Either the front or rear handles or both may be used to
lift or move the machine.
DO
NOT use the pull handle on the optional undercar-
riage, if installed, to lift the machine. This handle is not
designed to support the full weight of the machine and
using it to lift the machine could cause personal injury
or damage to the machine.
TILTING
The VIPER must be placed on a stable, level surface
so it will not topple over.
HIGH FREQUENCY INTERFERENCE
PROTECTION
The VIPER employs a touch start mechanism for arc
initiation which eliminates high frequency emissions
from the machine as compared with spark gap and
solid state type high frequency generators. Keep in
mind, though, that these machines may be used in an
environment where other high frequency generating
machines are operating. By taking the following
steps, high frequency interference into the VIPER can
be minimized
(1) Make sure the power supply chassis is connected
to a good earth ground. The work terminal ground
does NOT ground the machine frame.
(2) Keep the work ground clamp isolated from other
work clamps that have high frequency.
(3) If the ground clamp cannot be isolated, then keep
the clamp as far as possible from other work
clamp connections.
(4) When the machine is enclosed in a metal building,
several good earth driven electrical grounds
around the periphery of the building are recom-
mended.
Failure to observe these recommended installation
procedures may cause improper function of the
VIPER or possibly even damage to the control system
or power supply components.

AC Wave Form Restrictions
The VIPER can be operated on engine driven genera-
tors as long as the engine drive output meets the fol-
lowing conditions:
The AC wave form frequency is between 45 and 65
Hz.
For 200 - 230 VAC Supplies:
The AC wave form peak voltage must be below 420
volts.
The RMS voltage must be greater than 230VAC +/-
15%.
*The 230 VAC auxiliaries of Lincoln engine drives
meet these conditions when run in the high idle mode.
For 460 VAC Supplies:
The AC wave form peak voltage must be below 840
volts.
The RMS voltage of the AC wave form must be 460
VAC +/- 10%.
Input Power Restrictions
The available output current of the VIPER may be lim-
ited due to the output capacity of the engine driven
power supply. The following are recommended output
current settings when used with various Lincoln and
Red-D-Arc engine driven power supplies.

INSTALLATION

GAS INPUT CONNECTIONS
Supply the VIPER with clean compressed air or nitro-
gen.
Supply pressure must be between 80 psi
and 150 psi.
Flow rate should be approximately 6.0
cfm (170 I/min.).
NOTE: Oil in the air supply to the VIPER can cause
severe problems. Use only a clean air sup-
ply.
Connect the gas supply to the VIPER regula-
tor.
Compressed gas should be supplied to the fit-
ting connection mounted on the filter at the
rear of the machine. If necessary, this fitting
can be removed allowing plumbing access
through the 1/4” NPT input port on the filter
body.
If compressed air is being used, it is highly recom-
mended that an inline prefilter be installed in the air
supply line ahead of the air connection to the PRO-
CUT’s coalescing filter. While the coalescing filter is
used to remove small amounts of oil and water
aerosol particles from the air supply line, the prefilter
can be used to remove larger particulates before
they reach the coalescing filter element.This will pro-
long the life of the coalescing filter element by up to
six times what it would be without the prefilter, and in
turn, prolong the life of the PRO-CUT torch and con-
sumables as well.
• A standard nominal 5 micron inline prefilter is recom-
mended; however, for optimum performance,select a
prefilter with a 3 micron absolute rating. If these filter
ratings are unavailable, anything with a rating less
than, or equal to, 20 micron would be acceptable to
use. In line filter elements will generally filter the air
with little restriction to the airflow until the element is
about 75 % contaminated. After this point, there will
be a noticeable pressure drop in the line. Filter ele-
ments should be replaced when a pressure drop of
8-10 psi is indicated; however, for optimum perfor-
mance of the PRO-CUT, the filter element should be
replaced at or before the pressure drop reaches 8
psi. Be sure to select a prefilter that will accommo-
date the necessary flow rating for the PRO-CUT as
specified in the Installation section of this instruction
manual under the Gas Input Connections heading.
While it is recommended that an in line prefilter be
placed ahead of each PRO-CUT that may be
installed in a shared air supply line, one large inline
prefilter may instead be used to accommodate sev-
eral PRO-CUTs simultaneously. If a shared prefilter
is desired, it must be rated to provide the necessary
flow rate, as specified, to ensure proper operation of
each of the PRO-CUTs sharing a connection.
NOTE: When using nitrogen gas from a cylinder, the
cylinder must have a pressure regulator.
Maximum psi from nitrogen gas cylinder to
VIPER regulator should never
exceed 150 psi.
Install a hose between the nitrogen gas
cylinder regulator and the VIPER
gas inlet.
CYLINDER could explode if damaged.
• Keep cylinder upright and chained to a fixed sup-
port.
Keep cylinder away from areas
where it could be damaged.
Never lift machine with cylinder
attached.
Never allow the cutting torch to
touch the cylinder.
Keep cylinder away from live electrical
parts.
Maximum inlet pressure 150 psi.

Torch Connection
The VIPER is sent from the factory with a PCT 80 cut-
ting torch. Additional cutting torches can be ordered
from the K1571 series. Hand-held and mechanized
torches come with 25' or 50’ cables.
All torches are connected to the VIPER with a quick
connect on the case front for easy change over. This
feature is excellent for changing between a hand cut-
ting torch and a mechanized torch. This feature is also
handy for troubleshooting.
For more information on the torch and its components,
refer to the PCT80 Operator’s Manual (IM588 latest
version).

OPERATION
B-1
Read and understand this entire section before oper-
ating the machine.
SAFETY PRECAUTIONS
NOTE: All P.C. boards are protected by a moisture resistant
coating. When the plasma cutter is operated, this coating
will "bake off" of certain power resistors that normally oper-
ate at high temperatures emitting some smoke and odor for
a short time. These resistors and the P.C. board beneath
them may become darkened. This is a normal occurrence
and does not damage the component or affect the machine
performance.
DESCRIPTION
The VIPER is a constant current, continuous control
plasma cutting power source. It provides superior and
reliable starting characteristics, cutting visibility and
arc stability. When cutting expanded metal, the VIPER
out performs the competition due to its quick, clean
response to arc transfers. The power supply design
provides high transfer-to-cut distances which makes
pierce cutting more reliable and with less nozzle wear.
The control system has a safety mechanism to insure
that the nozzle and electrode are in place before cut-
ting or gouging. This is extremely important due to the
high voltages involved.
The VIPER comes standard with an air regulator,
coarse air filter, and pressure gauge. There are six dif-
ferent torch and cable systems to choose from: hand-
held torch with 25' or 50' cable, machine and robotic
torch both with 25' and 50' cable. Consumables are
included so that cutting can begin right out of the box.
Consumables can also be ordered as individual pack-
ages.
The VIPER initiates the plasma arc with a simple, yet
reliable, touch start mechanism. This system elimi-
nates many of the failure problems associated with hi-
frequency start systems. The VIPER is capable of cut-
ting with nitrogen or air.
The VIPER is controlled by a microprocessor-based
control board. The machine performs rudimentary self
troubleshooting when powered up which aids in field
servicing.
PREHEAT TEMPERATURE FOR
PLASMA CUTTING
Preheat temperature control is not necessary in most
applications when plasma arc cutting or gouging.
Preheat temperature control may be necessary on high
carbon alloy steels and heat treated aluminum for crack
resistance and hardness control. Job conditions, pre-
vailing codes, alloy level, and other considerations may
also require preheat temperature control. The following
minimum preheat temperature is recommended as a
starting point. Higher temperatures may be used as
required by the job conditions and/or prevailing codes.
If cracking or excessive hardness occurs on the cut
face, higher preheat temperature may be required. The
recommended minimum preheat temperature for plate
thickness up to 1/2" (12.7mm) is 70°F (21.1°C).

USER RESPONSIBILITY
Because design, fabrication, erection and cutting vari-
ables affect the results obtained in applying this type
of information, the serviceability of a product or struc-
ture is the responsibility of the user. Variation such as
plate chemistry, plate surface condition (oil, scale),
plate thickness, preheat, quench, gas type, gas flow
rate and equipment may produce results different than
those expected. Some adjustments to procedures
may be necessary to compensate for unique individ-
ual conditions. Test all procedures duplicating actual
field conditions.

CUTTING CAPABILITY
The VIPER is rated at 55 amps, at 50% duty cycle on a 10 minute basis or 40 amps, at 100% duty cycle. If the
duty cycle is exceeded, a thermal protector will shut off the output of the machine until it cools to the normal oper-
ating temperature.
Figure B.1 shows the cut capacity of the VIPER when cutting mild steel. The graph plots cut thickness vs. torch
travel speed with a torch standoff of 0.15". Example: 0.25” material may be cut at a setting of 35 amps at an
approximate speed of 38 IPM or at a setting of 45 amps at an approximate speed of 57 IPM or at a setting of 55
amps at an approximate speed of 62 IPM.

CONSUMABLE LIFE
The expected life for the VIPER's electrode under normal operating conditions is approximately 320 starts/cuts.
An erosion of .060" is typical for end of electrode life, however, the electrode life may last longer. A green and
erratic arc will indicate definite electrode failure and the electrode should be replaced immediately.
It is recommended that consumables be replaced in complete sets. (Example: Electrode and Nozzle). This will
maximize the performance of the VIPER system.

LIMITATIONS
Do not exceed output current and duty cycle rating of
machine. Do not use the VIPER for pipe thawing.
CONTROLS AND SETTINGS
When preparing to cut or gouge, position the machine
as close to the work as possible. Make sure you have
all materials needed to complete the job and have
taken all safety precautions. It is important to follow
these operating steps each time you use the machine.
Turn the machine's ON/OFF POWER SWITCH to
OFF position.
Connect the air supply to the machine.
1. TURN THE MAIN POWER AND THE MACHINE
POWER SWITCH ON.
- The fan should start.
- The pre-charge circuit will operate for 3 seconds,
then the green "Power" LED should turn on.
- If the "SAFETY" LED is lit, push the "Reset" but-
ton. If there is no problem, the LED will go off. If
there is a problem, refer to Step "SAFETY LED"
in this section.
- If any of the other LEDs remain lit and steady,
refer to the troubleshooting section of the manual.
Be sure that the work lead is clamped to the work-
piece before cutting.
Set the output current control knob at maximum
position for high cutting speed and less dross forma-
tion. Reduce the current, if desired to reduce the
kerf (cut) width, heat affected zone or travel speed
as required.
2. GAS PRESSURE SETTINGS.
Push-in and hold the Purge button to check or set
the gas pressure. Pull the pressure regulator cap
out and turn it to set the pressure.
- Adjust the gas regulator for 70 PSI for 25 torch-
es or 75 PSI for 50 torches.
- Release the Purge button.
- The gas will immediately turn off. The pressure
gage may show an increase in pressure after the
air turns off but this is normal. Do NOT reset the
pressure while the air is NOT flowing.
3. PREPARING TO CUT.
When ready to cut, place the torch near the work,
make certain all safety precautions have been taken
and pull the trigger.
- The air will flow for a preflow time of 2 seconds
and the pilot arc will start. (This is true unless
the machine is in postflow, then the preflow time
is skipped and the pilot arc will start immediate-
ly.)
- The pilot arc will run for 3.0 seconds and shut off
unless the arc is brought in contact with the work
and the arc is transferred. Avoid excessive pilot
arc time by transferring the arc to the workpiece
quickly to improve parts life.
- When the arc is brought within 1/4" from the
work piece: the arc will transfer, the current will
ramp up to the setting on the control panel, and
the cut can last indefinitely (or until the duty
cycle of the VIPER is exceeded). Do not touch
the nozzle to the work when cutting with the
control panel setting above 45 amps or damage
to the consumables will result.
Pierce the work piece by slowly lowering the torch
onto the metal at a 30
0
angle away from the opera-
tor. This will blow the dross away from the torch tip.
Slowly rotate the torch to vertical position as the arc
becomes deeper.

Hold the nozzle standoff 1/8 (3.2mm) to 3/16
(4.7mm) above the workpiece during cutting. Do not
let the torch nozzle touch the work or carry a long
arc.
Keep moving while cutting. Cut at a steady speed
without pausing. Maintain the cutting speed so that
the arc leg is 10° to 20° behind the travel direction.
Use a 5° - 15° leading angle in the direction of the
cut.
Use the drag cup to maintain constant standoff for
better cut quality and to protect the nozzle from spat-
ter.
Use the drag cup with a metal template to prevent
nozzle double arcing.
Finish the cut to be made and release the trigger.
When the trigger is released, the arc will stop.
- The gas will continue to flow for 10 seconds of
postflow. If the trigger is activated within this time
period, the pilot arc will immediately restart.
If the dross is difficult to remove, reduce the cutting
speed. High speed dross is more difficult to remove
than low speed dross.
The right side of the cut is more square than the left
as viewed along the direction of travel.
Tilt the torch about 45° from the workpiece and hold
the nozzle 1/8 (3.2mm) to 3/16 (4.7mm) above the
workpiece for gouging.
Clean spatter and scale from the nozzle and drag
cup frequently.
1. SAFETY LED
If the "SAFETY" LED lights at any time, check the
following:
2. IN NORMAL OPERATION, THE "SAFETY" LED
MAY TEMPORARILY ILLUMINATE AND CLEAR
ITSELF AUTOMATICALLY WITHOUT DEPRESS-
ING THE RESET BUTTON.
Check the assembly of the torch consumables. If
they are not properly in place, the machine will not
start. Make sure that the shield cup is hand tight.
Do not use pliers or over tighten.
Check the conditions of the inside of the nozzle. If
debris has collected, rub the electrode on the inside
bottom of the nozzle to remove any oxide layer that
may have built up. Refer to "Suggestions for Extra
Utility from the VIPER system".
Check the condition of the electrode. If the end has
a crater-like appearance, replace it along with the
nozzle. The maximum wear depth of the electrode is
approximately .060. A green and erratic arc will
indicate definite electrode failure and the electrode
should be replaced immediately.
Replace the nozzle when the orifice exit is eroded
away or oval shaped.
After the problem is found, or if there is nothing
apparently wrong, reset the machine by pressing
the "Reset" button. (It is possible for electrical noise
to trip the safety circuit on rare occasions. This
should not be a regular occurrence.)
If the machine does not reset or continues to trip,
consult the Troubleshooting Section.
Use the proper cutting or gouging procedures
referred to in Procedure Recommendations.

PILOT ARC DISCUSSION
The VIPER has a smooth, continuous pilot arc. The
pilot arc is only a means of transferring the arc to the
workpiece for cutting. Repeated pilot arc starts, in
rapid succession, is not recommended as these starts
will generally reduce consumable life. Occasionally,
the pilot arc may sputter or start intermittently. This is
aggravated when the consumables are worn or the air
pressure is too high. Always keep in mind that the
pilot arc is designed to transfer the arc to the work-
piece and not for numerous starts without cutting.
When the pilot arc is started, a slight impulse will be
felt in the torch handle. This occurrence is normal and
is the mechanism which starts the plasma arc. This
impulse can also be used to help troubleshoot a "no
start" condition.
PROCEDURE RECOMMENDATIONS
When properly used, plasma arc cutting or gouging is
a very economical process. Improper use will result in
a very high operating cost.
General - In All Cases
Follow safety precautions as printed throughout
this operating manual and on the machine.
Thin Gauge Sheet Metal:
1. OUTPUT SET BELOW 45 AMPS.
The nozzle may be dragged on the metal sur-
face, touching it lightly to the surface after pierc-
ing a hole. Current control should be set below
the mid range.
2. CURRENT CONTROL SHOULD BE SET BELOW
THE MID RANGE.
Do not allow cable or body to contact hot sur-
face.
Thick Sections of Metal
1. OUTPUT SET ABOVE 45 AMPS.
The best quality and consumable life will be
obtained by holding the torch off the surface
about 3/16". Too long an arc may compromise
cut quality and consumable life. The nozzle
should NOT be dragged on the work.
2. THE NOZZLE SHOULD NOT BE DRAGGED ON
THE WORK.
Failure to drag on the work will result in short-
ened consumable life.
Use of the S22151 Drag Cup will maintain the
proper standoff. The only reason not to use the
Drag Cup when the output control is set above
mid-range is in special, tight corners. Always
hold at least a 1/8" standoff in those situations.
If piercing is required, slowly lower the torch at
an angle of about 30° to blow the dross away
from the torch tip and slowly rotate the torch to
a vertical position as the arc becomes deeper.
This process will blow a lot of molten metal and
dross. Be careful! Blow the dross away from
the torch, the operator and any flammable
objects.
Where possible, start the cut from the edge of
the work piece.
Keep moving! A steady speed is necessary.
Do not pause.
Do not allow torch cable or body to contact hot
surface.

Suggestions for Extra Utility from the
VIPER System:
1. Occasionally an oxide layer may form over the tip
of the electrode, creating an insulating barrier
between the electrode and nozzle. This will result
in the tripping of the VIPER's safety circuit. When
this happens turn the power off, remove the nozzle
and electrode and use the electrode to rub against
the inside bottom surface of the nozzle. This will
help remove any oxide buildup. Replace the noz-
zle, turn on the power and continue cutting. If the
Parts-in-Place circuit continues to trip after clean-
ing the consumables, then replace them with a
new set. Do not continue to try and cut with exces-
sively worn consumables as this can cause dam-
age to the torch head and will degrade cut quality.
2. To improve consumable life, here are some sug-
gestions that may be useful:
a. Never drag the nozzle on the work surface if
the output control knob is above 45 amps.
b. Make sure the air supply to the VIPER is
clean and free of oil. Use several extra in line
filters if necessary.
c. Use the lowest output setting possible to make
a good quality cut at the desired cut speed.
d. Minimize dross buildup on the nozzle tip by
starting the cut from the edge of the plate
when possible.
e. Pierce cutting should be done only when nec-
essary. If piercing, angle torch about 30° from
the plane perpendicular to the work piece,
transfer the arc, then bring the torch perpen-
dicular to the work and begin parallel move-
ment.
f. Reduce the number of pilot arc starts without
transferring to the work.
g. Reduce the pilot arc time before transferring
to the work.
h. Set air pressure to recommended setting. A
higher or lower pressure will cause turbulence
in the plasma arc, eroding the orifice of the
nozzle tip.
i. Use only Lincoln consumable parts. These
parts are patented and using any other
replacement consumables may cause damage
to the torch or reduce cut quality.
