ELECTROMAGNETIC COMPATIBILITY (EMC)

EMC INTRODUCTION
Hypertherm's CE-marked equipment is built in compliance with standard EN50199. The equipment should be installed and used in accordance with the information below to achieve electromagnetic compatibility.
The limits required by EN50199 may not be adequate to completely eliminate interfer­ence when the affected equipment is in close proximity or has a high degree of sensitivity. In such cases it may be neces­sary to use other measures to further reduce interference.
This plasma equipment is designed for use only in an industrial environment.
INSTALLATION AND USE
The user is responsible for installing and using the plasma equipment according to the manufacturer's instructions. If electro­magnetic disturbances are detected then it shall be the responsibility of the user to re­solve the situation with the technical assis­tance of the manufacturer. In some cases this remedial action may be as simple as earthing the cutting circuit, see Earthing of Workpiece. In other cases it could involve constructing an electromagnetic screen enclosing the power source and the work complete with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where they are no longer troublesome.
ASSESSMENT OF AREA
Before installing the equipment the user shall make an assessment of potential elec­tromagnetic problems in the surrounding area. The following shall be taken into account: a. Other supply cables, control cables, signalling and telephone cables; above, below and adjacent to the cutting equip­ment. b. Radio and television transmitters and receivers. c. Computer and other control equipment. d. Safety critical equipment, for example guarding of industrial equipment. e. Health of the people around, for example the use of pacemakers and hear­ing aids. f. Equipment used for calibration or mea­surement. g. Immunity of other equipment in the en­vironment. User shall ensure that other equipment being used in the environment is compatible. This may require additional protection measures. h. Time of day that cutting or other activities are to be carried out.
Earthing of Workpiece
Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of its size and position, for example, ship's hull or building steelwork, a connection bonding the workpiece to earth may reduce emissions in some, but not all instances. Care should be taken to prevent the earthing of the workpiece increasing the risk of injury to users, or damage to other electrical equip­ment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries where direct connection is not permitted, the bonding should be achieved by suitable capacitances selected according to national regulations.
Note. The cutting circuit may or may not be earthed for safety reasons. Changing the earthing arrangements should only be au­thorized by a person who is competent to assess whether the changes will increase the risk of injury, for example, by allowing parallel cutting current return paths which may damage the earth circuits of other equipment. Further guidance is given in IEC TC26 (sec)94 and IEC TC26/108A/CD Arc Welding Equipment Installation and Use.
Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire plasma cutting installation may be considered for special applications
220/380/415V CE Power Supplies
The 220/380/415V CE power supply com­plies with the EMC European standard EN50199.
Information about this standard and other line filtering information pertaining to this power supply is located in Appendix D of this manual.
The size of the surrounding area to be considered will depend on the structure of the building and other activities that are tak­ing place. The surrounding area may extend beyond the boundaries of the premises.
METHODS OF REDUCING EMISSIONS
Mains Supply
Cutting equipment must be connected to the mains supply according to the manufactur­er's recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains supply. Consideration should be given to shielding the supply cable of per­manently installed cutting equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The shielding should be connect­ed to the cutting mains supply so that good electrical contact is maintained between the conduit and the cutting power source enclosure
Maintenance of Cutting Equipment
The cutting equipment must be routinely maintained according to the manufacturer's recommendations. All access and service doors and covers should be closed and properly fastened when the cutting equipment is in operation. The cutting equipment should not be modified in any way except for those changes and adjust­ments covered in the manufacturer's instructions. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and maintained according to the manufacturer's recommendations.
Cutting Cables
The cutting cables should be kept as short as possible and should be positioned close together, running at or close to the floor level.
Equipotential Bonding
Bonding of all metallic components in the cutting installation and adjacent to it should be considered. However, metallic compo­nents bonded to the workpiece will increase the risk that the operator could receive a shock by touching these metallic components and the electrode at the same time. The operator should be insulated from all such bonded metallic components.

Explosion Prevention
• Do not use the plasma system if explosive dust or vapors may be present.
• Do not cut pressurized cylinders, pipes, or any closed container.
• Do not cut containers that have held combustible materials.
CUTTING CAN CAUSE FIRE OR EXPLOSION
WARNING
Explosion Hazard
Argon-Hydrogen and Methane
Hydrogen and methane are flammable gases that present an explosion hazard. Keep flames away from cylinders and hoses that contain methane or hydrogen mixtures. Keep flames and sparks away from the torch when using methane or argon-hydrogen plasma.
WARNING
Hydrogen Detonation with Aluminum Cutting
• When cutting aluminum underwater, or with the water touching the underside of the aluminum, free hydrogen gas may collect under the workpiece and detonate during plasma cutting operations.
• Install an aeration manifold on the floor of the water table to eliminate the possibility of hydrogen detonation. Refer to the Appendix section of this manual for aeration manifold details.
Touching live electrical parts can cause a fatal shock or severe burn.
• Operating the plasma system completes an electrical circuit between the torch and the workpiece. The workpiece and anything touching the workpiece are part of the electrical circuit.
• Never touch the torch body, workpiece or the water in a water table when the plasma system is operating.
Electric Shock Prevention All Hypertherm plasma systems use high voltage
in the cutting process (200 to 400 VDC are common). Take the following precautions when operating this system:
• Wear insulated gloves and boots, and keep your body and clothing dry.
• Do not stand, sit or lie on – or touch – any wet surface when using the plasma system.
• Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground. If you must work in or near a damp area, use extreme caution.
• Provide a disconnect switch close to the power supply with properly sized fuses. This switch allows the operator to turn off the power supply quickly in an emergency situation.
• When using a water table, be sure that it is correctly connected to earth ground.
ELECTRIC SHOCK CAN KILL
• Install and ground this equipment according to the instruction manual and in accordance with national and local codes.
• Inspect the input power cord frequently for damage or cracking of the cover. Replace a damaged power cord immediately. Bare wiring can kill.
• Inspect and replace any worn or damaged torch leads.
• Do not pick up the workpiece, including the waste cutoff, while you cut. Leave the workpiece in place or on the workbench with the work cable attached during the cutting process.
• Before checking, cleaning or changing torch parts, disconnect the main power or unplug the power supply.
• Never bypass or shortcut the safety interlocks.
• Before removing any power supply or system enclosure cover, disconnect electrical input power. Wait 5 minutes after disconnecting the main power to allow capacitors to discharge.
• Never operate the plasma system unless the power supply covers are in place. Exposed power supply connections present a severe electrical hazard.
• When making input connections, attach proper grounding conductor first.
• Each Hypertherm plasma system is designed to be used only with specific Hypertherm torches. Do not substitute other torches which could overheat and present a safety hazard.
Cutting can produce toxic fumes and gases that deplete oxygen and cause injury or death.
• Keep the cutting area well ventilated or use an approved air-supplied respirator.
• Do not cut in locations near degreasing, cleaning or spraying operations. The vapors from certain chlorinated solvents decompose to form phosgene gas when exposed to ultraviolet radiation.
• Do not cut metal coated or containing toxic materi­als, such as zinc (galvanized), lead, cadmium or
CUTTING CAN PRODUCE TOXIC FUMES
beryllium, unless the area is well ventilated and the operator wears an air-supplied respirator. The coatings and any metals containing these elements can produce toxic fumes when cut.
• Never cut containers with potentially toxic materials inside – they must be emptied and properly cleaned first.
• This product, when used for welding or cutting, produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer.

SPECIFICATIONS
Description
General
This manual provides the information needed to install, operate and maintain the HD3070 plasma cutting system for either robotically controlled or x-y table cutting applications. This precision cutting, dual gas machine-torch system consists of a power supply, RHF console, gas console, torch quick disconnect assembly, off-valve assembly and machine torch assembly. Refer to Figures 2-1 and 2-2.
The HD3070 can be configured for different cutting applications by providing a selectable current output at 15, 30, 50, 70 or 100 amps for optimum performance on cutting most metals from gauge to 1/2-inch (12.7 mm) thick. This allows the operator wide variations in cutting speeds on the same thickness of metal. The gas console provides four inlets for the different plasma and shield gases required for different cutting applications. The HD3070 is designed to cut mild steel, stainless steel, copper and aluminum with the appropriate gases and consumables selected. Plasma gases required for cutting are oxygen, air, or H35 and nitrogen, depending on the application. The shield gas aids in assisting cut quality by providing an atmosphere around the plasma arc on the surface of the workpiece. The shield gas also cools the shield at the front end of the torch.
Under microprocessor control, the HD3070 provides extended life (LongLife) for the torch nozzle and electrode. To get long life, all cuts must begin and end on the plate surface; this allows for the proper ramping up and down of gases and DC current
Power Supply
This unit houses a 100-amp, 15 kw chopper which produces a constant current DC output, variable from 15 to 100 amps. It contains a microprocessor control PCB which regulates all the plasma system functions: start sequence, machine interface functions, gas and cut parameters, and off sequence. The power supply main on/off power is controlled locally or remotely by the CNC machine. The power supply also houses the cooling system required to cool the torch. The power supply interconnects with the RHF console, machine interface, gas console, and workpiece.
An EMI filter, standard with all 220/380/415V power supplies (078024), meets the CE requirement for filtering incoming power. Refer to Appendix D to connect incoming power to the filter and for part numbers.
Gas Console
This unit houses the solenoid valves, flowmeters, pressure gauges, and switches used for plasma and shield gas flow control. The four flowmeters (with metering valves) are used to set the test preflow flowrates and test cut flowrates for the plasma and shield gases. The three pressure gauges, located on the left side of the console, indicate the pressures of the set test preflow and test cut flowrates. These gauges should not be used to set the flowrates. They should be used only in troubleshooting, if the correct flowrate values cannot be obtained.
This unit also provides a five inlet gas supply area where the required plasma and shield gases can be connected. A toggle switch is used to select the plasma gases. The plasma and shield gases are monitored by three gas inlet pressure gauges: one for oxygen or air, one for nitrogen or methane, and one for H35.
The gas console interconnects with the power supply, and the torch off-valve assembly via the gas lead set.

SPECIFICATIONS
RHF Console
This unit houses the high frequency starting circuit which is needed to fire the torch and permits more effective RF shielding. The RHF Console has a water barrier to separate water and electrical components. Also housed in the console is a door interlock switch and a cathode manifold. The cathode manifold is used to interface power/coolant leads between the power supply and torch. The power/coolant leads and a pilot arc lead make up the shielded torch lead set which connects with the torch.
PAC184 Machine Torch Assemblies
The PAC184 machine torch is a dual gas (plasma and shield) plasma arc cutting torch. The slimmer design allows it to be used primarily in robotic cutting applications. The torch assembly includes the torch main body and consumables. The torch is cooled by a closed-loop system which distributes the coolant to and from the torch by way of the quick disconnect assembly, RHF console and the cooling subassemblies in the power supply. There are two torch assemblies: one torch assembly comes without an IHS tab on the shield cap; the other torch assembly comes with an IHS tab on the shield cap. See Figure 2-3.

The PAC186 machine torch is a dual gas (plasma and shield) plasma arc cutting torch designed for X-Y table cutting applications. The torch assembly includes the torch main body and consumables. The torch is cooled by a closed-loop system which distributes the coolant to and from the torch by way of the quick disconnect assembly, RHF console and the cooling subassemblies in the power supply. There are two torch assemblies: one torch assembly comes without an IHS tab on the shield cap; the other torch assembly comes with an IHS tab on the shield cap. See Figure 2-3.
45° Torch Quick Disconnect Assembly
The torch quick disconnect assembly is primarily used for robotic cutting applications. Inputs from the RHF console using the torch lead set are: electrode cooling water supply and return, power, and pilot arc. Inputs from the off­valve assembly are for torch blow back and plasma and shield gases. The quick disconnect also includes a 10 inch strain relief, which clamps on the end of the torch sleeve, to prevent damage to the leads and hoses.
Straight Torch Quick Disconnect Assembly
The torch quick disconnect assembly allows mechanized changing of torches by the cutting machine. Inputs from the RHF console using the torch lead set are: electrode cooling water supply and return, power, and pilot arc. Inputs from the off-valve assembly are for torch blow back and plasma and shield gases.
Off-Valve Assemblies
Two off-valve assemblies are offered: one with a blow back solenoid valve and the other without a blow back solenoid valve. Both off-valve assemblies provide on/off control between the preflow and operate gas flows. This

Power Supply Placement
Place the power supply according to the criteria below and the dimensions called out in Figure 3-1. Once the power supply has been placed, locate the line disconnect box on a wall near the power supply, so that the power supply can be quickly turned off in an emergency situation.
Note: A lifting eye is provided for moving the power supply into place with a crane or hoist. To access the lifting
eye, remove the 6 screws from the top cover and remove cover. It may also be moved by forklift if the forks are long enough to extend more than half way the length of the base. Care should be used when lifting with the forks so that the underside of the power supply is not damaged.
• Place the units in an area that is free of excessive moisture, has proper ventilation, and is relatively clean. Allow room for accessing the sides of the power supply for servicing.
• Place the power supply so that air flow is not blocked in any way. (Cooling air is drawn in through the front panel grating, and is exhausted through the rear of the unit by a cooling fan.) Do not place any filter device over the air intake locations. This reduces cooling efficiency and VOIDS THE WARRANTY.

Installation
This section provides the user with the necessary information to install the HD3070 system. Installation of the HD3070 System should not be undertaken unless all of the pre-installation requirements presented in front of this section have been completed. This section includes the following:
• Placing and mounting the system units.
• Interconnecting the units with the electrical control cables, cooling hoses and torch and gas lead sets.
• Mounting the PAC184 or PAC186 torch to the torch quick disconnect.
• Adding the torch coolant.
System Units Placement
Position the RHF console and gas console prior to making electrical, gas, and coolant connections. Also mount the torch quick disconnect and off-valve assembly. Note that power supply placement information is presented in Pre- Installation in the front of this section.
Remote High Frequency Console
Place the RHF console in a convenient location to allow easy routing and connection of the torch lead set. Bolt the unit to the mounting surface. See Figure 3-5.
Gas Console
Place the gas console in a convenient location near the operator for easy plasma gas and injection water monitoring adjustment. The gas console must be located within 100 feet of the torch. Bolt the unit to the mounting surface. See Figure 3-6.
Torch Quick Disconnect Assemblies/Off-Valve Assembly
The torch quick disconnect assemblies and off-valve assembly are shipped loose. The 45° quick disconnect, generally used with the PAC184 torch, is normally mounted onto a robotic arm using the four 1/4-20 mounting holes. See Figure 3-7 for torch quick disconnect mounting hole dimensions.
The straight quick disconnect assembly, generally used with the PAC186 torch, is normally mounted onto a torch lifter on a x-y cutting table.
The off-valve assembly may be mounted up to a distance of four feet from either of the torch quick disconnects.

Cable, Hose & Lead Set Interconnections
The following cable, hose and lead set interconnecting procedures are supported by the system interconnection diagram, Figure 3-8. Also provided are illustrations of each unit showing where the connections are to be made and illustrations of the cables, hoses and lead sets.
Note that these procedures and supporting illustrations are cross referenced (, , etc.) to ensure a safe and correct installation. Also note that the cross referencing numbers do not indicate a sequence for interconnecting. It is assumed that in most cases the interconnections will be routed through a power track or festoon system from one point to the other.
IMPORTANT
When interfacing with the CNC, optically isolated I/Os or ground floating interfaces are recommended to avoid ground shift and make the system more immune to EMI noises.

Torch Coolant Requirements
The power supply is shipped without any coolant in the tank. A standard mixture of propylene glycol (30%), deionized water (69.9%) and benzotriazole (0.1%) is recommended. This mixture resists freezing to +10° F (-12° C) and contains a corrosion inhibitor (benzotriazole) to protect copper surfaces in the coolant loop. This mixture is available in 1-gallon containers by ordering 028872. 100% propylene glycol is available by ordering 028873.
Freezing torch coolant can result in a cracked torch head, leads, or other damage to the torch cooling system. For operating temperatures colder than +10° F (-12° C), the percentage of propylene glycol must be increased. See Figure 3-31.
Coolant will become more conductive the longer it is in service. If the conductivity of the coolant becomes too high, the coolant may conduct torch voltage, resulting in the torch misfiring and can be a shock hazard. Check coolant conductivity whenever the cooling system is serviced.
Conductivity of new coolant mixture should not exceed 10 µ Siemens/cm at 77° F (25° C). Every 6 months, flush the power supply of its torch coolant and replace with new coolant.
Observe the warning and caution below. Refer to the Material Safety Data Sheets in Appendix A for data on safety, handling, storage and disposal of propylene glycol and benzotriazole.
Caution: Always use propylene glycol in the coolant mixture. Do not use anti- freeze in
place of propylene glycol. Antifreeze contains corrosion inhibitors which will damage the torch coolant system.
Always use purified water in the coolant mixture in order to prevent corrosion in the torch coolant system. The hardness of purified water should be between
0.206 and 8.5 ppm. If using a conductivity meter to measure water purity, the recommended level is between 0.5 and 18 µ Siemens/cm at 77° F (25° C).
WARNING
Propylene glycol and benzotriazole are irritating to skin and eyes, and harmful or fatal if swallowed. Upon
contact, flush skin or eyes with water. If swallowed drink water and call a physician immediately. Do not induce vomiting.

Filling Torch Coolant System
1. Before proceeding with filling the system with coolant:
Ensure that your cutting environment and clothing meet the safety requirements. Refer to Safety, Section 1 in this manual.
Ensure that all installation requirements in this manual have been met.
Caution: Never turn the power supply on before filling the tank.
2. Turn on the inlet gas supplies to the gas console. Ensure the gases are available at 120 psi (8.2 bar).
3. At the rear of the power supply, ensure the coolant shutoff valve (1, Figure 3-32) is open and unscrew the filler/vent cap (3) on coolant tank (2). Fill tank with 8.5 quarts (8 liters) of coolant.
Caution: Do not over fill the tank.
4. At the line voltage disconnect box, set the switch to On.
5. Turn on the power supply by depressing and holding the POWER ON (I) pushbutton switch/ indicator (PB1/LT1). The COOLANT FLOW LED will remain out until the coolant has pushed all of the air out of the torch cooling hoses and the coolant returns to the tank. This process may take up to 60 seconds.
6. Locate the red button (5, Figure 3-32) on top of the coolant filter (4) at the rear of the power supply. Press the button until a little coolant comes out and no air bubbles are seen in the clear filter housing.
7. When the COOLANT FLOW LED illuminates, release the POWER ON (I) pushbutton (PB1). The green POWER ON indicator (LT1) should light, indicating that the system is operating normally.
8. Observe that the coolant gauge indicates F (Full). Refill the tank when the gauge indicates 1/2 or a little under. Do not allow the coolant to get too low. Low coolant will overheat and cause shorter consumable life.
9. Check for coolant leaks at hose connections at the power supply, RHF console, and torch quick disconnect.

Daily Start-Up Procedure
Prior to start-up, ensure that your cutting environment and that your clothing meet the safety requirements outlined in Section 1, Safety. If problems occur during start-up, refer to Section 3, Installation to check installation requirements and procedures. The daily start-up procedure involves setting up the system for cutting as follows:
1. Check that the consumable parts are not worn or damaged. Refer to Changing Consumable Parts in this section.
2. Select cutting current at the AMPS thumbwheel (S1).
Always use the cutting current for which the consumables are rated. For example, do not select 25 or 35 amps for 30 amp consumables. Cutting at a current other than the rated current will cause excessive consumable wear and unpredictable cutting performance. It will also be more difficult to troubleshoot cutting faults, since baseline data does not exist for other than the 30 amp current.
3. Check that the torch is perpendicular to the workpiece to get a clean, vertical cut. Use a square to align the
torch. The torch should be aligned at 0° and 90°.
4. Set initial torch height using the suggested initial height data from the Cut Charts.
Torch initial height sensing should be accurate and consistent for good electrode and nozzle life. When the initial height is too high, the pilot arc is prevented or prolonged from transferring to the cutting arc. When the initial height is too low, pierce slag can build up on the shield increasing the chance for a double- arc on subsequent starts. If a pierce is made with the shield touching the workpiece, the molten slag will be forced between the nozzle and shield, rendering the shield gas useless and probably ruining the shield and nozzle.
5. Set arc voltage on torch height control unit (THC) using the suggested arc voltage data from the Cut Charts.
One (1) arc volt equals approximately .005 inch (.127 mm).
Arc voltage is typically how the torch height is maintained above the workpiece during a cut. A higher arc voltage will maintain a higher standoff between the torch and workpiece. The arc voltage potential is between the tip of the electrode (actually the bottom of the pit in the hafnium element) and the workpiece being cut. As the electrode tip wears, a pit is formed and the arc voltage may have to be increased to compensate for the longer distance that now exists between the bottom of the pit and the workpiece. For example, after a few hundred starts, the torch will ride closer to the workpiece causing an undercut cut edge. To correct the undercut, simply increase the arc voltage setting by a couple of arc volts. The torch standoff distance will increase, and cut quality will return.
6. Set the PIERCE DELAY potentiometer (P1) to the suggested pierce delay data on the Cut Charts.
7. Select the plasma gas with the PROCESS SELECTION toggle switch (S1) on the gas console right side panel.
8. Check that the gas inlet supplies are connected and available at 120 psi (8.2 bar) on the inlet gas pressure
gauges (PG1, PG2, and PG3). It is important to keep equal values of the pressures to obtain the correct
mixtures of the gases.
9. Set the main disconnect switch for the power supply to On.
10. Turn on the power supply by depressing the POWER ON (1) switch (PB1). Check that the green POWER ON indicator (LT1) lights. If not, check the STATUS LEDs. Refer to Front Panel Controls and Indicators in this section.
4-8 HD3070 with Manual Gas Console Instruction Manual
15
OPERATION
11. Establish plasma and shield gas flows for cutting as follows.
Set TEST PRE/RUN/TEST CUT toggle switch (S2) on the gas console to TEST CUTFLOW.
Note: The metering valves normally turn hard. Do not loosen the packing nut around the valve stems to make
the valves turn more easily. Loosening the packing nuts breaks the seals and allows gases to leak out around the valve stems.
Turn the PLASMA metering valves (MV1 and MV2) to set required flowrates on flowmeters (FM1 and FM2). See Cut Charts for required flowrates.
Turn the SHIELD metering valves (MV3 and MV4) to set required flowrates on flowmeters (FM3 and FM4). See Cut Charts for required flowrates.
12. Establish preflow gas flows as follows.
Set TEST PRE/RUN/TEST CUT toggle switch (S2) on the gas console to TEST PREFLOW.
Turn the PREFLOW metering valves (MV5 and MV6) to set the required flowrates on flowmeters (FM3 and
FM4). See Cut Charts for required flowrates.
13. If correct flowrate values cannot be obtained, check the associated pressure gauges on the left side of the gas console to check the back pressure. Refer to the Section 5, Maintenance, to perform the gas system back pressure check.
14. Purge the gas lines by positioning the TEST PRE/RUN/TEST CUT toggle switch (S2) on the gas console to TEST CUTFLOW for 20 seconds and then position the switch to TEST PREFLOW for 20 seconds. After purging the gas lines, set the switch to RUN.
15. The system is now ready for operation.

OPERATION
Changing Consumable Parts
Inspect torch consumable parts before cutting for wear and damage, and replaced when needed. The PAC184 and PAC186 torch consumable parts kits (refer to Section 6, Parts List contain tools for removal and inspection of the consumable parts. To remove, inspect and replace the consumables, proceed as follows. See Figures 4-3 – 4-6.
Removal and Inspection
1. Remove the shield cap and inspect shield for plugged holes or damage. To remove the shield, push on it until it releases. Check the O-ring for wear and damage.
2. Remove the inner cap and inspect for plugged holes or damage.
3. Remove the nozzle using the removal tool. Check for wear and arcing. Also check the O-rings for wear and damage.
4. Remove the electrode using the removal tool. The electrode should be inspected and replaced if there is a pit .040 inch (1 mm) deep. See Figure 4-6 in order to check the pit depth. Check the O-ring for wear and damage.
5. Remove the swirl ring using the removal tool. Insert the tool into the swirl ring until it catches on the lip and then pull back to remove swirl ring. Inspect the swirl ring for plugged holes or damage. Check the O-rings for wear and damage.
Replacement
Do not use an excessive amount of silicone grease when applying to any of the consumable O-rings. Excess grease can easily plug ports and holes, causing improper gas flow during operation. Only apply a light coat of silicone grease.
Avoid touching the tip of the electrode during installation as grease or dirt may affect starting reliability. Check the electrode tip and wipe clean if necessary.
1. Apply silicone to the electrode O-ring and then to both O-rings on the swirl ring.
2. Insert the electrode into the small diameter end of the swirl ring, then insert the swirl ring (large diameter end) into the nozzle. Apply silicone to the nozzle O-rings, then insert the nozzle into the torch and push it into place.
3. Inspect the threads on the torch main body, and clean threads if necessary. Apply silicone to the O-rings on the torch main body.
WARNING
Always disconnect the power supply from the main power source before inspecting or changing the torch parts.

OPERATION
4. Install the inner cap on to the torch main body. Hand tighten the inner cap snugly to ensure good electrical
contact. Do not overtighten.
5. Install the shield cap with the shield in place on to the torch main body. If the shield is not in place, apply silicone to the O-ring and insert the shield into the shield cap and push into place. Hand tighten the shield cap
snugly. Failure to tighten the shield cap snugly could result in poor electrical contact and water and gas leaks which will impair cut quality.
Blow Back Option to Purge Coolant Hoses
Before removing the PAC184 or PAC186 torch, the operator may want to purge the torch coolant from the coolant hoses back into the coolant tank to minimize the coolant dripping when the torch is disconnected from the quick disconnect. After replacing the torch, the coolant hoses should be refilled with coolant. Refer to the procedures below.
Purge Coolant Hoses (Blow Back)
1. Shut the power supply down at the control panel or CNC.
2. At off-valve assembly (Fig. 4-7) connect 1/4-inch air hose to air inlet.
3. Connect 120 VAC power cable from CNC or other source to blow back solenoid valve.
4. Apply air at approximately 20 psi (1.4 bar) to the air inlet. Air supply should be clean, dry and oil free in
order not to contaminate the coolant.
5. Apply 120 VAC signal for about 3 seconds to open the solenoid valve in order to purge the coolant from the hoses. It is not necessary to purge longer than 3 seconds.
6. After the coolant hoses have been purged, disconnect the torch from the torch quick disconnect.

OPERATION
Refill Coolant Hoses
1. Reconnect torch to the torch quick disconnect.
2. Apply power to the power supply at the control panel or from CNC. If at the power supply, depress and hold the POWER ON pushbutton switch until the COOLANT FLOW LED lights. If at the CNC, maintain the Power On signal until the COOLANT FLOW LED lights.
When the COOLANT FLOW LED lights, release the POWER ON switch at the power supply or the Power On signal at the CNC. The green POWER ON indicator should remain on, indicating that the system is operating normally.
(The COOLANT FLOW LED will remain out until the coolant has pushed all of the air out of the torch cooling hoses and the coolant returns to the tank. However, coolant hoses with too many bends can have air pockets even though the COOLANT FLOW LED lights and the system appears ready for operation. The trapped air
can cause the torch to lose cooling momentarily and potentially cause damage to the torch.)

How to Optimize Cut Quality
The following tips and procedures will help produce square, straight, smooth and dross-free cuts.
Tips for Table and Torch
Use a square to align the torch at right angles to the workpiece.
The torch may travel more smoothly if you clean, check and tune the rails and drive system on the cutting
table. Unsteady machine motion can cause a regular, wavy pattern on the cut surface.
The torch must not touch the workpiece during cutting. Contact can damage the shield and nozzle, and affect the cut surface.
Plasma Set-Up Tips
Follow carefully each step in the Daily Start-Up procedure described earlier in this section.
Purge the gas lines before cutting.
Maximize the Life of Consumable Parts
Hypertherms LongLife®process automatically ramps up the gas and current flows at the start and ramps them down at the end of each cut, to minimize erosion of the electrodes center surface. The LongLife process also requires that cuts start and stop on the workpiece.
The torch should never fire into the air.Starting the cut at the edge of the workpiece is acceptable, as long as the arc is not fired in the air.
To start with a pierce, use a pierce height that is 1.5 to 2 times the torch-to-work distance. See Cut Charts.
Each cut should end with the arc still attached to the workpiece, to avoid arc blow-outs (ramp-down errors).When cutting drop parts (small parts that drop down after being cut from the workpiece), check that the
arc stays attached to the edge of the workpiece, for proper ramp-down.
If arc blow-outs occur, try one or more of the following: Reduce the cutting speed during the final part of the cut.Stop the arc before the part is completely cut, to allow completion of the cut during the ramp-down.Program the path of the torch into the scrap area for ramp-down.
Note: Use a chain cut if possible, so the path of the torch can lead directly from one cut part into
the next, without stopping and starting the arc. However, do not allow the path to lead off the workpiece and back on, and remember that a chain cut of long duration will cause electrode wear.
Note: It may be difficult to achieve the full benefits of the LongLife process in some conditions.
