WARNING
PLASMA CUTTING or GOUGING can be hazardous.
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 pur­chase 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.
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 frame­work such as floors, gratings or scaffolds and when in posi­tions 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 con­nection 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 elec­trical (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.
ARC RAYS can burn.
2.a. Use safety glasses and a shield with the prop­er 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.
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 employ­er’s safety practices.
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, spe­cial precautions should be used to prevent hazardous situa­tions. Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1) and the operating information for the equip­ment being used.
4.c. When not cutting or gouging, make certain no part of the elec­trode circuit is touching the work or ground. Accidental con­tact can cause overheating and create a fire hazard.
4.d. Do not cut or gouge tanks, drums or containers until the prop­er 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.
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
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

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 build­ing 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.
CYLINDER may explode if damaged.
5.a. Use only compressed gas cylinders contain­ing the correct gas for the process used and properly operating regulators designed for the
gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.
5.b. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.
5.c. Cylinders should be located:
• Away from areas where they may be struck or subjected to
physical damage.
• A safe distance from plasma cutting or gouging, arc weld-
ing operations and any other source of heat, sparks, or flame.
5.d. Never allow any part of the electrode, torch or any other electrically “hot” parts to touch a cylinder.
5.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
5.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.
5.g. Read and follow the instructions on compressed gas cylin­ders, associated equipment, and CGA publication P-l, “Precautions for Safe Handling of Compressed Gases in Cylinders,”available from the Compressed Gas Association 1235 Jefferson Davis Highway, Arlington, VA 22202.
FOR ELECTRICALLY powered equipment.
6.a. Turn off input power using the disconnect switch at the fuse box before working on the equipment.
6.b. Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manufacturer’s rec­ommendations.
6.c. Ground the equipment in accordance with the U.S. National Electrical Code and the manufacturer’s recommendations.
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.
ELECTRIC AND MAGNETIC FIELDS
may be dangerous
8.a. Electric current flowing through any con­ductor causes localized Electric and Magnetic Fields (EMF). Cutting or gouging current cre­ates EMF fields around torch cables and cutting machines.
8.b. EMF fields may interfere with some pacemakers, so opera­tors 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.

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 suiv­antes:
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.
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 lev­age, 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.
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 ray­onnement 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, pan­talons 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
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 debranch­er à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur place.

SAFETY PRECAUTIONS
WARNING
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 PYTHON ground­ing terminal (located on the side of the Case Back Assembly) to a good electrical earth ground.
Turn the PYTHON Power Switch OFF when connecting power cord to input power.
___________________________________________
LIFTING AND MOVING
Either the front or rear handles or both may be used to lift or move the machine.
NOT use the pull handle on the optional undercar-
DO
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 PYTHON must be placed on a stable, level sur­face so it will not topple over.
HIGH FREQUENCY INTERFERENCE PROTECTION
The PYTHON 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 PYTHON can be minimized
SELECT PROPER LOCATION
Place the PYTHON where clean cool air can freely cir­culate in through the rear louvers and out through the side/bottom openings. 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 nuisance shutdown of the machine.
A source of clean, dry air or nitrogen must be supplied to the PYTHON. Oil in the air is a severe problem and must be avoided. The supply pressure must be between 80 and 120 psi. The flow rate is approximate­ly 8.0 cfm (227 l/min.). Failure to observe these pre­cautions could result in excessive operating tempera­tures or damage to the torch.
STACKING
The PYTHON cannot be stacked.
(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 recom­mended.
Failure to observe these recommended installation procedures may cause improper function of the PYTHON or possibly even damage to the control sys­tem or power supply components.

• Pressure gage, located on the front of the machine, should be set to approximately 70 PSI for a 25 ft. torch and 75 PSI for a 50 ft. torch while gas is flowing (purging or cutting).
Flow rate should be approximately 8.0 cfm (227 I/min.).
NOTE: Oil in the air supply to the PYTHON can
cause severe problems. Use only a clean air supply.
Connect the gas supply to the PYTHON regu-
lator.
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 recom­mended that an inline prefilter be installed in the air supply line ahead of the air connection to the PRO­CUT’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 prolong 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 consumables as well.
• While it is recommended that an inline prefilter be placed ahead of each PRO-CUT, that may be in stalled in a shared air supply line, one large in line prefilter may instead be used to accommodate sev­eral PRO-CUT’s simultaneously. If a shared pre is desired, it must be rated to provide the necessary flow rate, as specified, to ensure proper operation of each of the PRO-CUT’s sharing a connection.
NOTE: When using nitrogen gas from a cylinder, the
cylinder must have a pressure regulator.
Maximum psi from the nitrogen gas cylinder to the PYTHON regulator should never exceed 120 psi.
Install a hose between the nitrogen gas cylinder regulator and the PYTHON gas inlet.
WARNING
CYLINDER could explode if damaged.
• Keep cylinder upright and chained to a fixed support.
• 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 120 psi.
__________________
OUTPUT CONNECTIONS
• A standard nominal 5 micron inline prefilter is rec­ommended; however, for optimum performance, select a prefilter with a 3 micron absoluterating.If these filter ratings are unavailable, anything with a rating less than, or equal to, 20 micron would be acceptable to use. Inline 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 bea noticeable pressure drop in the line. Filter elements should be replaced when a pressure drop of 8-10 psi is indicated; however, for optimum performance 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 accommodate the necessary flow rating for the PRO-CUT as specified in the Installation sec­tion of this instruction manual under the Gas Input Connections heading.
Torch Connection
The PYTHON is sent from the factory with a PCT 80 cutting 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 PYTHON with a quick connect on the case front for easy change over. This feature is excellent for changing between a hand cut­ting torch and a mechanized torch.
For more information on the torch and its components, refer to the PCT80 Operator’s Manual (IM588 latest version).

The PYTHON 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 PYTHON 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 cutting or gouging. This is extremely important due to the high voltages involved.
The PYTHON comes standard with an air regulator, coarse air filter, and pressure gauge. There are six dif­ferent torch and cable systems to choose from: hand­held 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 pack­ages.
The PYTHON initiates the plasma arc with a simple, yet reliable, touch start mechanism. This system elimi­nates many of the failure problems associated with hi­frequency start systems. The PYTHON is capable of cutting with nitrogen or air.
The PYTHON is controlled by a microprocessor­based 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, pre­vailing 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 vari­ables affect the results obtained in applying this type of information, the serviceability of a product or struc­ture 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 individ­ual conditions. Test all procedures duplicating actual field conditions.
RECOMMENDED PROCESSES AND EQUIPMENT
The PYTHON is capable of all cutting and gouging applications within its output capacity of 35 to 85 amps. These applications include thin gage sheet metal and expanded metal.

CUTTING CAPABILITY
The PYTHON is rated at 80 amps, at 60% duty cycle on a 10 minute basis or 60 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 oper­ating temperature.
Figure B.1 shows the cut capacity of the PYTHON when cutting mild steel. The graph plots cut thickness vs. torch travel speed with a torch standoff of 0.15". Example: 0.5” material may be cut at a setting of 55 amps at an approximate speed of 25 IPM or at a setting of 80 amps at an approximate speed of 35 IPM.

CONSUMABLE LIFE
The expected life for the PYTHON's electrode under normal operating conditions is approximately 160 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 PYTHON system.

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.

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 torch­es 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 immediate­ly.)
- 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 PYTHON 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 300angle away from the opera­tor. This will blow the dross away from the torch tip. Slowly rotate the torch to vertical position as the arc becomes deeper.
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" but­ton. If there is no problem, the LED will go off. If there is a problem, refer to Step "SAFETY LED" in this section.
Be sure that the work lead is clamped to the work­piece before cutting.
Set the output current control knob at maximum position for high cutting speed and less dross forma­tion. Reduce the current, if desired to reduce the kerf (cut) width, heat affected zone or travel speed as required.

If the "SAFETY" LED lights at any time, check the following:
WARNING
ELECTRIC SHOCK CAN KILL.
Turn off machine at the disconnect switch on the front of the machine before tightening, cleaning or replacing consumables.
----------------------------------------------------------------------------
2. IN NORMAL OPERATION, THE "SAFETY" LED MAY TEMPORARILY ILLUMINATE AND CLEAR ITSELF AUTOMATICALLY WITHOUT DEPRESS­ING 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.
Finish the cut 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.
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 PYTHON 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 .062. 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 PYTHON 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 work­piece 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.
THICK SECTIONS OF METAL:
Torch Standoff
1/8" thru 3/16"
Standoff
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.
2. THE NOZZLE SHOULD NOT BE DRAGGED ON THE WORK.
Failure to drag on the work will result in short­ened consumable life.
Use of the S22151 Drag Cup will maintain the proper standoff and eliminate nozzle double arcing.

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.
Do not allow cable or body to contact hot sur­face.

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.
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 PYTHON'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 nozzle, turn on the power and continue cutting. If the Parts-in-Place circuit continues to trip after cleaning the consumables, then replace them with a new set. Do not continue to try and cut with excessively worn consumables as this can cause damage 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 set above 3. (Approximately 45 amps output).
b. Make sure the air supply to the PYTHON 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 perpen­dicular to the work and begin parallel move­ment.
MACHINE INTERFACE
The PYTHON comes standard with a machine inter­face. Interface signals provided include: arc start, arc initiated, and arc voltage. These signals are accessi­ble through the 14 pin MS connector on the case front.
ARC START:
The Arc Start circuit allows for triggering of the power source to commence cutting. This circuit can be accessed through pins K and M of the 14 pin MS con­nector. The circuit has a 17 VDC nominal open circuit voltage and requires a dry contact closure to activate.
ARC INITIATED:
The Arc Initiated circuit provides information as to when a cutting arc has transferred to the work piece. This circuit can be accessed through pins I and J of the 14 pin MS connector. The circuit provides a dry contact closure when the arc has transferred. Input to this circuit should be limited to 0.3 A for either 120VAC or 30VDC.
ARC VOLTAGE:
The Arc Voltage circuit can be used for activating a torch height control. This circuit can be accessed through pins D and G of the 14 pin MS connector. The circuit provides full electrode to work arc voltage (no voltage divider, 335VDC maximum).

ROUTINE MAINTENANCE
1. Keep the cutting or gouging area and the area around the machine clean and free of combustible materials. No debris should be allowed to collect which could obstruct air flow to the machine.
2. Every 6 months or so, the machine should be cleaned with a low pressure airstream. Keeping the machine clean will result in cooler operation and higher reliability. Be sure to clean these areas:
- Power, Output and Control printed circuit boards and heat sinks
- Power switch
- Main Transformer
- Input Rectifier
3. Examine the sheet metal case for dents or break­age. Repair the case as required. Keep the case in good condition to insure that high voltage parts are protected and correct spacings are maintained. All external sheet metal screws must be in place to insure case strength and electrical ground continu­ity.
4. Check the air regulator filter to be sure it does not become clogged. The air filter on the machine is self draining and will not have to be emptied.
5. Check the filter element every several months to see if it is clogged (weekly in very dirty environ­ments). Replace if necessary by first removing the two screws that attach the filter cage to the back panel assembly, then slide the cage away from the back of the machine and remove. Next, twist the clear filter bowl until it comes off (be careful not to lose the o-ring seated at the top of the bowl threads). Unscrew the filter element and replace with new element. Assemble parts in reverse order as described above.
6. Inspect the cable periodically for any slits or punc­ture marks in the cable jacket. Replace if neces­sary. Check to make sure that nothing is crushing the cable and blocking the flow of air through the air tube inside. Also, check for kinks in the cable periodically and relieve any so as not to restrict the flow of air to the torch.
PERIODIC MAINTENANCE
WARNING
ELECTRIC SHOCK CAN KILL.
Turn off machine at the disconnect switch on the front of the machine before tightening, cleaning or replacing consumables.
----------------------------------------------------------------------------
Change consumables as required.
1. Thermal Protection Two thermostats protect the machine from excessive
operating temperatures. Excessive temperatures may be caused by a lack of cooling air or operating the machine beyond the duty cycle and output rating. If excessive operating temperatures should occur, the yellow thermal LED will light and the thermostat will prevent output voltage or current.
Thermostats are self-resetting once the machine cools sufficiently. If the thermostat shutdown was caused by excessive output or duty cycle and the fan is operating normally, the Power Switch may be left on and the reset should occur within a 15 minute period. If the fan is not turning or the air intake louvers were obstructed, then the power must be switched off and the fan prob­lem or air obstruction must be corrected.
2. Filter Capacitor Conditioning (PYTHON, 400-460 VAC or 460-575 VAC)
A protection circuit is included to monitor the voltage across filter capacitors C1 and C2. In the event that the capacitor voltage is too high, the protection circuit will prevent output. The protection circuit may prevent output providing all these circumstances are met:
a. Machine is connected for 400-460 VAC or 460-
575 VAC input.
b. Machine did not have power applied for many
months.
c. Machine will not produce output when power is
first switched on.
If these circumstances apply, the proper action is to switch the machine on and let it idle for up to 30 min­utes. This is required to condition the filter capacitors after an extended storage time. The protection circuit will automatically reset once the capacitor conditioning and resultant voltage levels are acceptable. It may be necessary to turn the power switch off and back on again after this period.

When the trigger is pulled air begins to flow, but there is no pilot arc after at least 3 seconds.
The air begins to flow and there is a very brief arc that snaps out consis­tently with repeated trigger pulls.
1.
Check the torch consumables to be sure they are not dirty or greasy, and are in good shape. Replace the consumables if necessary.
2. Make sure the air pressure is set at 70 psi (75 psi for a 50 ft. torch).
3. Make sure there are no kinks or restrictions for air flow in the torch cable. Replace cable as needed.
4. If a slight thump cannot be felt in the torch when the trigger is pulled, check for loose connection in the torch head and solenoid assembly.
5. With machine turned off - input power removed, and torch and consumables connected - mea­sure resistance on Output Power board between B1 and B21. If >10Ω, possible fault in torch and cable assembly.
6. Possible fault in Output board.
1. Check the torch consumables to be sure they are in tight, not dirty or greasy and in good shape. Replace if necessary.
If all recommended possible areas of misadjustment have been checked and the problem persists, Contact
your local Lincoln Authorized Field Service Facility.
2. Make sure the air pressure is set at 70 psi.
Possible fault in Output Power board.
3.
The arc starts but sputters badly.
1. Check the torch consumables to be sure they are in tight, not dirty or greasy and in good shape. Replace if necessary.
2. Check air supply for oil or a great deal of water. If there is oil or a great deal of water, the air must be filtered or the machine switched to nitrogen or bottled air.
3.
Make sure the air pressure is set at 70 psi.
CAUTION
If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.

SYMPTOM
Machine is unresponsive immediately after power-up.
The Air Low LED is lit
The Safety LED is flashing
The Safety LED is lit and steady
CHECK
1. There is a 4 second soft start period for pre-charging the input fil­ter capacitors. Wait until that time is up. The Power LED will light when ready. If not, refer to the first part of this section.
1. Make sure there is at least 80 psi connected to the gas connec­tion at the back of the machine.
2. Press the Purge button and set the regulator to 70 psi (75 psi for a 50 ft. torch). The pressure may increase when air stops flowing but this is normal. Do not reset the pressure while the air is OFF.
3. Possible faulty Pressure Switch.
4. Possible faulty Control board.
1. Make sure there is a Lincoln torch and cable assembly connect­ed properly to the PYTHON bulk head connector.
2. Check consumables for proper installation or excessive wear. Replace if excessively worn. If not, use a piece of fine emery cloth to remove any oxide buildup on the tip of the electrode.
1. Press the Reset button. If torch and consumables are properly installed, the Safety LED should turn off. Normal cutting or goug­ing can resume.
The Thermal LED is lit
The Ready”, “Air Low and Thermal LED’s are flashing
1. The machine's thermostat has tripped due to exceeded duty cycle limits. Do NOT turn the power off. Allow the machine to cool for 15 - 30 minutes and the thermostat will reset itself.
2. The machine's air louvers or fans are obstructed such that air cannot flow to properly cool the machine. Remove any foreign material that may block air flow. Blow the machine out with a clean, dry air stream.
3. Possible faulty Control board.
1. This is typically caused by connecting the auxiliary transformer input tap to the wrong voltage. Turn machine OFF and change lead to correct input voltage at reconnect panel.
2. Possible faulty Control P. C. Board.
