ELECTROMAGNETIC COMPATIBILITY (EMC)

EMC INTRODUCTION

Hypertherm's CE-marked equipment is builtin compliance with standard EN50199. Theequipment should be installed and used inaccordance with the information below toachieve electromagnetic compatibility.

The limits required by EN50199 may not beadequate to completely eliminate interfer-ence when the affected equipment is inclose proximity or has a high degree of sen-sitivity. In such cases it may be necessary touse other measures to further reduce inter-ference.

This plasma equipment is designed for useonly in an industrial environment.

INSTALLATION AND USE

The user is responsible for installing andusing the plasma equipment according tothe manufacturer's instructions. If electro-magnetic disturbances are detected then itshall be the responsibility of the user to re-solve the situation with the technical assis-tance of the manufacturer. In some casesthis remedial action may be as simple asearthing the cutting circuit, see Earthing ofWorkpiece. In other cases it could involveconstructing an electromagnetic screen en-closing the power source and the work com-plete with associated input filters. In allcases electromagnetic disturbances mustbe reduced to the point where they are nolonger troublesome.

ASSESSMENT OF AREA

Before installing the equipment the usershall make an assessment of potential elec-tromagnetic problems in the surroundingarea. The following shall be taken intoaccount:a. Other supply cables, control cables, sig-nalling and telephone cables; above, belowand adjacent to the cutting equipment.b. Radio and television transmitters andreceivers.c. Computer and other control equipment.d. Safety critical equipment, for exampleguarding of industrial equipment.e. Health of the people around, for example the use of pacemakers and hear-ing aids.f. Equipment used for calibration or mea-surement.g. Immunity of other equipment in the en-vironment. User shall ensure that otherequipment being used in the environment iscompatible. This may require additional pro-tection measures.h. Time of day that cutting or other activitiesare to be carried out.

Earthing of Workpiece

Where the workpiece is not bonded to earthfor electrical safety, nor connected to earthbecause of its size and position, for example,ship's hull or building steelwork, a connectionbonding the workpiece to earth may reduceemissions in some, but not all instances.Care should be taken to prevent the earthingof the workpiece increasing the risk of injuryto users, or damage to other electrical equip-ment. Where necessary, the connection ofthe workpiece to earth should be made by adirect connection to the workpiece, but insome countries where direct connection isnot permitted, the bonding should beachieved by suitable capacitances selectedaccording to national regulations.

Note. The cutting circuit may or may not beearthed for safety reasons. Changing theearthing arrangements should only be au-thorized by a person who is competent toassess whether the changes will increasethe risk of injury, for example, by allowingparallel cutting current return paths whichmay damage the earth circuits of otherequipment. Further guidance is given in IECTC26 (sec)94 and IEC TC26/108A/CD ArcWelding Equipment Installation and Use.

Screening and Shielding

Selective screening and shielding of othercables and equipment in the surroundingarea may alleviate problems of interference.Screening of the entire plasma cutting in-stallation may be considered for special ap-plications

The size of the surrounding area to be con-sidered will depend on the structure of thebuilding and other activities that are takingplace. The surrounding area may extendbeyond the boundaries of the premises.

METHODS OF REDUCING EMISSIONS

Mains Supply

Cutting equipment must be connected to themains supply according to the manufactur-er's recommendations. If interference oc-curs, it may be necessary to take additionalprecautions such as filtering of the mainssupply. Consideration should be given toshielding the supply cable of permanentlyinstalled cutting equipment, in metallic con-duit or equivalent. Shielding should be elec-trically continuous throughout its length.The shielding should be connected to thecutting mains supply so that good electricalcontact is maintained between the conduitand the cutting power source enclosure

Maintenance of Cutting Equipment

The cutting equipment must be routinelymaintained according to the manufacturer'srecommendations. All access and servicedoors and covers should be closed andproperly fastened when the cutting equip-ment is in operation. The cutting equipmentshould not be modified in any way except forthose changes and adjustments covered inthe manufacturer's instructions. In particu-lar, the spark gaps of arc striking and stabi-lizing devices should be adjusted and main-tained according to the manufacturer'srecommendations.

Cutting Cables

The cutting cables should be kept as shortas possible and should be positioned closetogether, running at or close to the floorlevel.

Equipotential Bonding

Bonding of all metallic components in thecutting installation and adjacent to it shouldbe considered. However, metallic compo-nents bonded to the workpiece will increasethe risk that the operator could receive ashock by touching these metallic compo-nents and the electrode at the same time.The operator should be insulated from allsuch bonded metallic components.

CAUTION safety messages precede relatedinstructions in this manual that may result indamage to equipment if not followed correctly.

Fire Prevention Be sure the area is safe before doing any cutting.

Keep a fire extinguisher nearby. Remove all flammables within 35 feet (10 m) of the

cutting area. Quench hot metal or allow it to cool before handling

or before letting it touch combustible materials. Never cut containers with potentially flammable

materials inside they must be emptied andproperly cleaned first.

Ventilate potentially flammable atmospheres beforecutting.

When cutting with oxygen as the plasma gas, anexhaust ventilation system is required.

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

WARNINGExplosion Hazard

Argon-Hydrogen and MethaneHydrogen and methane are flammable gases thatpresent an explosion hazard. Keep flames away fromcylinders and hoses that contain methane or hydrogenmixtures. Keep flames and sparks away from the torchwhen using methane or argon-hydrogen plasma.

WARNINGHydrogen Detonation with Aluminum Cutting

When cutting aluminum underwater, or with thewater touching the underside of the aluminum, freehydrogen gas may collect under the workpiece anddetonate during plasma cutting operations.

Install an aeration manifold on the floor of the watertable to eliminate the possibility of hydrogendetonation. Refer to the Appendix section of thismanual for aeration manifold details.

Touching live electrical parts can cause a fatal shockor severe burn. Operating the plasma system completes an

electrical circuit between the torch and theworkpiece. The workpiece and anything touchingthe workpiece are part of the electrical circuit.

Never touch the torch body, workpiece or the waterin a water table when the plasma system isoperating.

Electric Shock PreventionAll Hypertherm plasma systems use high voltagein the cutting process (200 to 400 VDC arecommon). Take the following precautions whenoperating 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 anyphysical contact with the work or ground. If you mustwork in or near a damp area, use extreme caution.

Provide a disconnect switch close to the powersupply with properly sized fuses. This switch allowsthe operator to turn off the power supply quickly inan emergency situation.

When using a water table, be sure that it is correctlyconnected to earth ground.

ELECTRIC SHOCK CAN KILL

Install and ground this equipment according to theinstruction manual and in accordance with nationaland local codes.

Inspect the input power cord frequently for damageor cracking of the cover. Replace a damaged powercord immediately. Bare wiring can kill.

Inspect and replace any worn or damaged torchleads.

Do not pick up the workpiece, including the wastecutoff, while you cut. Leave the workpiece in placeor on the workbench with the work cable attachedduring the cutting process.

Before checking, cleaning or changing torch parts,disconnect the main power or unplug the powersupply.

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 powerto allow capacitors to discharge.

Never operate the plasma system unless the powersupply covers are in place. Exposed power supplyconnections present a severe electrical hazard.

When making input connections, attach propergrounding conductor first.

Each Hypertherm plasma system is designed to beused only with specific Hypertherm torches. Do notsubstitute other torches which could overheat andpresent a safety hazard.

Cutting can produce toxic fumes and gases thatdeplete oxygen and cause injury or death.

Keep the cutting area well ventilated or use anapproved air-supplied respirator.

Do not cut in locations near degreasing, cleaning orspraying operations. The vapors from certainchlorinated solvents decompose to form phosgenegas when exposed to ultraviolet radiation.

Do not cut metal coated or containing toxic materi-als, such as zinc (galvanized), lead, cadmium or

CUTTING CAN PRODUCE TOXIC FUMES

beryllium, unless the area is well ventilated and theoperator wears an air-supplied respirator. Thecoatings and any metals containing these elementscan produce toxic fumes when cut.

Never cut containers with potentially toxic materialsinside they must be emptied and properly cleanedfirst.

This product, when used for welding or cutting,produces fumes or gases which contain chemicalsknown to the State of California to cause birthdefects and, in some cases, cancer.

Theory of Operation

General

Refer to Functional Description, Sequence of Operation and the system wiring diagram in Section 6.

Functional DescriptionAC power enters the system through the power switch S1 to the input diode bridge D24. The voltage from the diodebridge supplies the Power Factor Correction (PFC) Boost Converter which provides a 750 VDC bus voltage. Thebus voltage then supplies the inverter and the flyback system power supply (DC to DC converter) on the powerboard PCB2. The power board provides noise suppression and spike protection. A "soft start" is implemented viathe power board resistor and relay K1.

The PFC Boost Converter consists of an isolated gate bipolar transistor (IGBT) Q7, choke and control circuit. It provides a750 VDC bus voltage when input AC voltage is between 170 and 540 VAC. When the input voltage is above 540 VAC thebus voltage will rise to Vin* 2.

The inverter consists of an IGBT Q6, the power transformer T2, a current sense transformer, and sections of the powerboard. The inverter operates as a pulse-width, modulator-controlled bridge circuit, and is rectified by the outputdiode.

The output circuitry consists of 2 current transfer sensors located on the power board, the pilot arc IGBT Q8 andthe output choke.

The control boards microprocessor monitors and regulates system operation and safety circuits. The current is setto the desired value by adjusting the current adjustment knob. The system compares the set point to the outputcurrent by monitoring the current sensor and adjusting the pulse width output of the inverter IGBT Q6.

The control board PCB3 includes a pilot arc control switch, allowing the operator to turn the pilot arc ON (usefulwhen cutting expanded metal), OFF (for maximum life of consumables), or increase the pilot arc to 20A (useful forgouging or non-transferred-arc cutting).

MAINTENANCE


WARNINGELECTRIC SHOCK CAN KILL Turn off the power and remove the input power plug from its receptacle before removing

the cover from the power supply. If the power supply is directly connected to a linedisconnect box, switch the line disconnect to OFF (O). In the U.S., use a "lock-out / tag-out" procedure until the service or maintenance work is complete. In other countries,follow appropriate national or local safety procedures.

Do not touch live electrical parts! If power is required for servicing, use extreme cautionwhen working near live electrical circuits. Dangerous voltages exist inside the powersupply that can cause serious injury or death.

Do not attempt to repair the power board or control board. Do not cut away or removeany protective conformal coating from either board. To do so will risk a short circuitbetween the AC input circuit and the output circuit and may result serious injury ordeath.

HOT PARTS CAN CAUSE SEVERE BURNS Allow the power supply to cool before servicing.

MOVING BLADES CAN CAUSE INJURY Keep hands away from moving parts.

STATIC ELECTRICITY CAN DAMAGE CIRCUIT BOARDS Put on a grounded wrist strap before handling PC boards.

Visual Inspection Internal

1. Set the ON/OFF switch S1 to O (OFF), unplug the power cord and disconnect the gas supply.

2. Remove the cover of the power supply by removing the 12 securing screws.

3. Inspect the inside of the power supply, especially on the side with the power board. Look for broken or loosewiring connections, burn and char marks, damaged components, etc. Repair or replace as necessary.

MAINTENANCE


Resistance ChecksAll resistance values must be taken with the power cord disconnected and all internal power supply wires attached.Perform Visual Inspection Internal before continuing in this section.

If resistance values are not close to the values given in this section, isolate the problem by removing wiresattached to the resistance check points or component until the problem is found.

After the problem has been located and repaired, refer to the Sequence of Operation flow diagram in thissection to test the power unit for proper operation.
