ELECTRIC AND MAGNETIC FIELDSmay be dangerous
2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines
2.b. EMF fields may interfere with some pacemakers, andwelders having a pacemaker should consult their physicianbefore welding.
2.c. Exposure to EMF fields in welding may have other healtheffects which are now not known.
2.d. All welders should use the following procedures in order tominimize exposure to EMF fields from the welding circuit:
2.d.1. Route the electrode and work cables together - Securethem with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode andwork cables. If the electrode cable is on your right side, the work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close aspossible to the area being welded.
2.d.5. Do not work next to welding power source.
1.h. To avoid scalding, do not remove theradiator pressure cap when the engine ishot.

ARC RAYS can burn.4.a. Use a shield with the proper filter and cover
plates to protect your eyes from sparks andthe rays of the arc when welding or observingopen arc welding. Headshield and filter lensshould conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistantmaterial to protect your skin and that of your helpers fromthe arc rays.
4.c. Protect other nearby personnel with suitable, non-flammablescreening and/or warn them not to watch the arc nor exposethemselves to the arc rays or to hot spatter or metal.
ELECTRIC SHOCK cankill.3.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder is on.Do not touch these “hot” parts with your bareskin or wet clothing. Wear dry, hole-free
gloves to insulate hands.
3.b. Insulate yourself from work and ground using dry insulation.Make certain the insulation is large enough to cover your fullarea of physical contact with work and ground.
In addition to the normal safety precautions, if weldingmust be performed under electrically hazardousconditions (in damp locations or while wearing wetclothing; on metal structures such as floors, gratings orscaffolds; when in cramped positions such as sitting,kneeling or lying, if there is a high risk of unavoidable oraccidental contact with the workpiece or ground) usethe following equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.• DC Manual (Stick) Welder.• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode,electrode reel, welding head, nozzle or semiautomaticwelding gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electricalconnection with the metal being welded. The connectionshould be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical(earth) ground.
3.f. Maintain the electrode holder, work clamp, welding cable andwelding machine in good, safe operating condition. Replacedamaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts ofelectrode holders connected to two welders because voltagebetween the two can be the total of the open circuit voltageof both welders.
3.i. When working above floor level, use a safety belt to protectyourself from a fall should you get a shock.
3.j. Also see Items 6.c. and 8.
FUMES AND GASEScan be dangerous.5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing thesefumes and gases.When welding, keepyour head out of the fume. Use enoughventilation and/or exhaust at the arc to keep
fumes and gases away from the breathing zone. Whenwelding with electrodes which require specialventilation such as stainless or hard facing (seeinstructions on container or MSDS) or on lead orcadmium plated steel and other metals or coatingswhich produce highly toxic fumes, keep exposure aslow as possible and below Threshold Limit Values (TLV)using local exhaust or mechanical ventilation. Inconfined spaces or in some circumstances, outdoors, arespirator may be required. Additional precautions arealso required when welding on galvanized steel.
5.b. Do not weld in locations near chlorinated hydrocarbon vaporscoming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors toform phosgene, a highly toxic gas, and other irritating products.
5.c. Shielding gases used for arc welding can displace air andcause injury or death. Always use enough ventilation,especially in confined areas, to insure breathing air is safe.
5.d. Read and understand the manufacturer’s instructions for thisequipment and the consumables to be used, including thematerial safety data sheet (MSDS) and follow youremployer’s safety practices. MSDS forms are available fromyour welding distributor or from the manufacturer.
5.e. Also see item 1.b. Mar ‘95
FOR ELECTRICALLYpowered equipment.
8.a. Turn off input power using the disconnectswitch at the fuse box before working onthe equipment.
8.b. Install equipment in accordance with the U.S. NationalElectrical Code, all local codes and the manufacturer’srecommendations.
8.c. Ground the equipment in accordance with the U.S. NationalElectrical Code and the manufacturer’s recommendations.
CYLINDER may explodeif damaged.7.a. Use only compressed gas cylinders
containing the correct shielding gas for theprocess used and properly operatingregulators designed for the gas and
pressure used. All hoses, fittings, etc. should be suitable forthe application and maintained in good condition.
7.b. Always keep cylinders in an upright position securelychained to an undercarriage or fixed support.
7.c. Cylinders should be located:• Away from areas where they may be struck or subjected tophysical damage.
• A safe distance from arc welding or cutting operations andany other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any otherelectrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outletwhen opening the cylinder valve.
7.f. Valve protection caps should always be in place and handtight except when the cylinder is in use or connected foruse.
7.g. Read and follow the instructions on compressed gascylinders, associated equipment, and CGA publication P-l,“Precautions for Safe Handling of Compressed Gases inCylinders,” available from the Compressed Gas Association1235 Jefferson Davis Highway, Arlington, VA 22202.

WELDING SPARKS cancause fire or explosion.6.a. Remove fire hazards from the welding area.
If this is not possible, cover them to preventthe welding sparks from starting a fire.Remember that welding sparks and hot
materials from welding can easily go through small cracksand openings to adjacent areas. Avoid welding nearhydraulic lines. Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site,special precautions should be used to prevent hazardoussituations. Refer to “Safety in Welding and Cutting” (ANSIStandard Z49.1) and the operating information for theequipment being used.
6.c. When not welding, make certain no part of the electrodecircuit is touching the work or ground. Accidental contactcan cause overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until theproper steps have been taken to insure that such procedureswill not cause flammable or toxic vapors from substancesinside. They can cause an explosion even though they havebeen “cleaned”. For information, purchase “RecommendedSafe Practices for the Preparation for Welding and Cutting ofContainers and Piping That Have Held HazardousSubstances”, AWS F4.1 from the American Welding Society(see address above).
6.e. Vent hollow castings or containers before heating, cutting orwelding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oilfree protective garments such as leather gloves, heavy shirt,cuffless trousers, high shoes and a cap over your hair. Wearear plugs when welding out of position or in confined places.Always wear safety glasses with side shields when in awelding area.
6.g. Connect the work cable to the work as close to the weldingarea as practical. Work cables connected to the buildingframework or other locations away from the welding areaincrease the possibility of the welding current passingthrough lifting chains, crane cables or other alternate cir-cuits. This can create fire hazards or overheat lifting chainsor cables until they fail.

PRÉCAUTIONS DE SÛRETÉPour votre propre protection lire et observer toutes les instructionset les précautions de sûreté specifiques qui parraissent dans cemanuel aussi bien que les précautions de sûreté générales suiv-antes:
Sûreté Pour Soudage A L’Arc1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode et à la piéce sont sous tensionquand la machine à souder est en marche. Eviter toujourstout contact entre les parties sous tension et la peau nueou les vétements mouillés. Porter des gants secs et sanstrous pour isoler les mains.
b. Faire trés attention de bien s’isoler de la masse quand onsoude dans des endroits humides, ou sur un planchermetallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grandepartie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câblede soudage et la machine à souder en bon et sûr étatdefonctionnement.
d.Ne jamais plonger le porte-électrode dans l’eau pour lerefroidir.
e. Ne jamais toucher simultanément les parties sous tensiondes porte-électrodes connectés à deux machines à souderparce que la tension entre les deux pinces peut être letotal de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source decourant pour soudage semi-automatique, ces precautionspour le porte-électrode s’applicuent aussi au pistolet desoudage.
2. Dans le cas de travail au dessus du niveau du sol, se protégercontre les chutes dans le cas ou on recoit un choc. Ne jamaisenrouler le câble-électrode autour de n’importe quelle partiedu 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 appropriéainsi qu’un verre blanc afin de se protéger les yeux du ray-onnement de l’arc et des projections quand on soude ouquand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger lapeau de soudeur et des aides contre le rayonnement del‘arc.
c. Protéger l’autre personnel travaillant à proximité ausoudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc desoudage. Se protéger avec des vêtements de protection libresde l’huile, tels que les gants en cuir, chemise épaisse, pan-talons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone desoudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin deprévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé dela masse. Un court-circuit accidental peut provoquer unéchauffement et un risque d’incendie.
8. S’assurer que la masse est connectée le plus prés possiblede la zone de travail qu’il est pratique de le faire. Si on placela masse sur la charpente de la construction ou d’autresendroits éloignés de la zone de travail, on augmente le risquede voir passer le courant de soudage par les chaines de lev-age, câbles de grue, ou autres circuits. Cela peut provoquerdes risques d’incendie ou d’echauffement des chaines et descâbles 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 tôlesgalvanisées plombées, ou cadmiées ou tout autre métal quiproduit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenantd’opérations de dégraissage, nettoyage ou pistolage. Lachaleur ou les rayons de l’arc peuvent réagir avec les vapeursdu 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” CSAStandard W 117.2-1974.
PRÉCAUTIONS DE SÛRETÉ POURLES MACHINES À SOUDER ÀTRANSFORMATEUR ET ÀREDRESSEUR
1. Relier à la terre le chassis du poste conformement au code del’électricité et aux recommendations du fabricant. Le dispositifde montage ou la piece à souder doit être branché à unebonne mise à la terre.
2. Autant que possible, I’installation et l’entretien du poste seronteffectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la debranch-er à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leurplace.

ENVIRONMENTAL PROTECTIONThe Power Wave power source is rated IP21S andshould not be subjected to falling water, nor shouldany parts of it be submerged in water. Doing so maycause improper operation as well as pose a safetyhazard. The best practice is to keep the machine in adry, sheltered area.
LIFTINGLift the machine by the lift bail only. The lift bail isdesigned to lift the power source only. Do not attemptto lift the Power Wave with accessories attached to it.
MACHINE GROUNDING
The frame of the welder must be grounded. A groundterminal marked with the symbol is located insidethe reconnect/input access door for this purpose. Seeyour local and national electrical codes for propergrounding methods.
HIGH FREQUENCY PROTECTION
If possible, locate the Power Wave away from radiocontrolled machinery. The normal operation of thePower Wave may adversely affect the operation of RFcontrolled equipment, which may result in bodily injuryor damage to the equipment.
INPUT CONNECTION
Only a qualified electrician should connect the inputleads to the Power Wave. Connections should bemade in accordance with all local and national electri-cal codes and the connection diagram located on theinside of the reconnect/input access door of themachine. Failure to do so may result in bodily injuryor death.
-------------------------------------------------------------
Use a three-phase supply line. A 1.75 inch (45 mm)diameter access hole for the input supply is located onthe upper left case back next to the input access door.Connect L1, L2, L3 and ground according to the InputSupply Connection Diagram decal located on theinside of the input access door or refer to Figure A.1following.
Read this entire installation section before youstart installation.
SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Only qualified personnel shouldperform this installation.
• Turn the input power OFF at thedisconnect switch or fuse boxbefore working on this equipment.
• Do not touch electrically hot parts.
• Always connect the Power Wave grounding lug(located inside the reconnect input access door) toa proper safety (Earth) ground.
-------------------------------------------------------------
SELECT SUITABLE LOCATIONPlace the welder where clean cooling air can freelycirculate in through the rear louvers and out throughthe case sides and bottom. Dirt, dust, or any foreignmaterial that can be drawn into the welder should bekept at a minimum. Using filters on the air intake toprevent dirt from building up restricts air flow. Donot use such filters. Failure to observe these precau-tions can result in excessive operating temperaturesand nuisance shutdowns.
This machine (above code 10500 only) is equippedwith F.A.N. (fan as needed) circuitry. The fan runswhenever the output is enabled, whether underloaded or open circuit conditions. The fan also runs fora period of time (approximately 5 minutes) after theoutput is disabled, to ensure all components are prop-erly cooled.
If desired, the F.A.N. feature can be disabled (causingthe fan to run whenever the power source is on). Todisable F.A.N., connect leads 444 and X3A togetherat the output of the solid state fan control relay, locat-ed on the back of the Control PC board enclosure.
STACKINGPower Wave machines can be stacked to a maximumof 3 high. The bottom machine must always beplaced on a firm, secure, level surface. There is adanger of machines toppling over if this precaution isnot taken.

INPUT FUSE AND SUPPLY WIRE CONSIDERATIONSRefer to the Technical Specifications at the beginningof this Installation section for recommended fuse andwire sizes. Fuse the input circuit with the recommend-ed super lag fuse or delay type breakers (also called“inverse time” or “thermal/magnetic” circuit breakers).Choose an input and grounding wire size according tolocal or national electrical codes. Using fuses or cir-cuit breakers smaller than recommended may result in“nuisance” shut-offs from welder inrush currents, evenif the machine is not being used at high currents.
INPUT VOLTAGE RECONNECT PROCEDURE
Only a qualified electrician should connect the inputleads to the Power Wave. Connections should bemade in accordance with all local and national electri-cal codes and the connection diagram located on theinside of the reconnect/input access door of themachine. Failure to do so may result in bodily injury ordeath.------------------------------------------------------------------------
Welders are shipped connected for the highest inputvoltage listed on the rating plate. To move this con-nection to a different input voltage, refer to reconnect
instructions located on the inside of the input accessdoor or in Figure A.1. If the main reconnect switch isplaced in the wrong position, the welder will not pro-duce output power. If the Auxiliary (“A”) lead is placedin the wrong position, there are two possible results.If the lead is placed in a position higher than theapplied line voltage, the welder may not come on atall. If the Auxiliary (“A”) lead is placed in a positionlower than the applied line voltage, the welder will notcome on, and the two circuit breakers in the reconnectarea will open. If this occurs, turn off the input volt-age, properly connect the “A” lead, reset the breakers,and try again.
OUTPUT CONNECTIONS
Use the largest welding (electrode and ground) cablespossible — at least 2/0, 4/0 preferred, copper wire —even if the average output current would not normallyrequire it. When pulsing, the pulse current canexceeds 650 amps. Voltage drops can becomeexcessive, leading to poor welding characteristics, ifundersized welding cables are used.
To avoid interference problems with other equipmentand to achieve the best possible operation, route allcables directly to the work or wire feeder. Avoidexcessive lengths, bundle the electrode and groundcables together where practical, and do not coilexcess cable.

VOLTAGE SENSING AT THE WORKPIECE
A four-pin work piece voltage sense lead connector islocated beneath the output stud cover. The use of awork piece sense lead is optional for most weldingmodes, but may be used if desired.
Sense Lead Kits (K490-10, -25 or -50) are availablefor this purpose.
To enable the work piece voltage sensing lead, ajumper must be removed from the Control PC Boardas follows:
1) Turn the Power Wave 455 power OFF.
2) Remove the front nameplate from the Power Wave455 by removing the six screws from the name-plate. Save the screws for re-use.
3) Locate P26, located on the upper right edge of theControl PC Board. It is a 16 pin connector withonly two wires going into it. Unplug P26. It shouldremain attached to the main harness.
4) Install the front nameplate on the Power Wave 455by replacing the six screws saved in Step 2.
5) Plug a Sense Lead into the Sense LeadReceptacle. Note: Only the lead marked ‘WORK’is used. The lead marked ‘ELECT’ can be cut offand discarded.
6) Connect the WORK sense lead clamp to the piecebeing welded.
The Power Wave 455 will now use the external workpiece Sense Lead to sense arc voltage in all weldingmodes. If the Sense Lead is enabled but not connect-ed to the work piece, extremely high welding outputcurrents may result.
To restore normal work piece sensing (at the outputterminals) reconnect P26 to the Control PC board.The Sense Lead can then be disconnected.
POWER WAVE / POWER FEED WIREFEEDER INTERCONNECTIONS
ELECTRODE & WORK LEADS —ELECTRODE POSITIVE APPLICATIONS
Most welding applications run with the electrode beingpositive (+). For those applications, connect the elec-trode cable between the wire feeder and the positive(+) output stud on the power source (located beneaththe spring loaded output cover near the bottom of thecase front).
A work lead must be run from the negative (-) powersource output stud to the work piece. The work piececonnection must be firm and secure, especially ifpulse welding is planned. Excessive voltage drops atthe work piece connection often result in unsatisfacto-ry pulse welding performance.
ELECTRODE & WORK LEADS —ELECTRODE NEGATIVE APPLICATIONS
When negative electrode polarity is required, such asin some Innershield™ applications, install as above,except reverse the output connections at the powersource (electrode cable to the negative (-) stud, andwork cable to the positive (+) stud).
CONTROL CABLE CONNECTIONS
Connect the control cable between the wire feederand power source. The power source wire feederconnection is located under the spring loaded outputcover, near the bottom of the case front. The controlcable is keyed and polarized, so it can be installed inonly one way.
For neatness and convenience sake, both the elec-trode and control cables can be routed behind the leftor right strain reliefs (under the spring loaded outputcover), and along the channels formed into the baseof the Power Wave, out the back of the channels, andthen to the wire feeder.

POWER FEED CONTROL BOXMOUNTING
In some installations, it may be desirable to mount theWire Feeder control box directly to the front of thePower Wave power source. (The control box is thebox containing the knobs, switches and displays nec-essary to control the Power Wave / Power Feed weld-ing system.) Complete details for separating the con-trol box from the wire drive are contained in the PowerFeed Instruction Manual. Once separated, mountinginstructions are as follows:
1. Disconnect the input power from the Power Wave.
2. Separate the control box from the wire drive on thePower Feed wire feeder, and remove the controlpanels (see the Power Feed Instruction Manual fordetails).
3. Remove the front nameplate from the Power Waveby removing six screws from the metal nameplate.Save the screws for re-use.
4. Connect the 6-pin connector that comes out theback of the control box to the 6-pin receptacle thatis tie-wrapped to the harnessing inside the rectan-gular opening in the power source. It will be nec-essary to remove one or two of the wire ties inorder to give enough slack to the power sourceconnector and leads.
5. Position the control box over the rectangular holein the Power Wave case front, being careful not topinch any leads between the control box and thecase front. Align the four holes in the back of thecontrol box with the four threaded mounting holesin the case front. Secure the control box in placewith four of the screws saved from the previousstep.
6. Reassemble the control box.
The Power Feed Wire Drive can now be connected tothe power source wire feeder connector. This con-nector is located under the spring loaded outputcover, near the bottom of the case front. The controlcable is keyed and polarized, so it can be installed inonly one way. (To ensure proper electrode voltagesensing, always connect the Wire Drive to the PowerSource wire feeder connector. Do not connect it tothe optional Output Receptacle which may be presenton the Power Feed Control Box.)

WELDING ADJUSTMENTS
All adjustments are made on the system componentknown as the control box, which contains the switch-es, knobs and digital displays necessary to controlboth the Power Wave and a Power Feed wire feeder.Typically, the control box is supplied as part of thewire feeder. It can be mounted directly on the wirefeeder itself, or mounted separately, as might be donein a welding boom installation.
Because the control box can be configured with manydifferent options, your system may not have all of thefollowing adjustments. Regardless of availability, allcontrols are described below. For further information,consult the Power Feed wire feeder instruction manual.
1. WFS / AMPS:In synergic welding modes (synergic CV, pulseGMAW) WFS (wire feed speed) is the dominantcontrol parameter, controlling all other variables.The user adjusts WFS according to factors such asweld size, penetration requirements, heat input, etc.The Power Wave then uses the WFS setting toadjust its output characteristics (output voltage, out-put current) according to pre-programmed settingscontained in the Power Wave. In non-synergicmodes, the WFS control changes the wire feedspeed according to the desired procedure.
In constant current modes (stick, TIG) this controladjusts the output current, in amps.
2. VOLTS / TRIM:In constant voltage modes (synergic CV, standardCV) the control adjusts the welding voltage.
In pulse synergic welding modes (pulse GMAWonly) the user can change the Trim setting to adjustthe arc length. It is adjustable from 0.500 to 1.500.A Trim setting of 1.000 is a good starting point formost conditions.
3. WELDING MODE:May be selected by name (CV/MIG, CC/Stick Crisp,Gouge, etc.) or by a mode number (10, 24, 71, etc.)depending on the control box options. Selecting awelding mode determines the output characteristicsof the Power Wave power source. For a morecomplete description of the welding modes avail-able in the Power Wave, see the explanationbelow.
4. ARC CONTROL:Also known as Inductance or Wave Control. Allowsoperator to vary the arc characteristics from “soft”to “harsh” in all weld modes. It is adjustable from -
10.0 to +10.0, with a nominal setting of 00.0. (Thenominal setting of 00.0 may be displayed as OFFon some Power Feed wire feeder control panels.)See the Welding Mode descriptions, below, fordetailed explanations of how the Arc Control affectseach mode.
DETAILED WELD MODE DESCRIPTIONS
CONSTANT VOLTAGE (CV/WELD, CV/MIG,CV/FLUX CORED) PROCEDURES
For each wire feed speed, a corresponding voltage ispreprogrammed into the machine through special soft-wares at the factory. This preprogrammed voltage isthe best average voltage for the procedure at thegiven wire feed speed. If the wire feed speed ischanged on the wire feeder, the voltage automaticallychanges with it.
In some cases, the operator may want to change thepreprogrammed voltages; for example, to compensatefor cable and fixture voltage drops. The preset volt-ages can be adjusted on the wire feeder’s Voltagedisplay. When a change is made to the voltage atone wire feed speed, this change is applied to allother wire feed speed settings. For example, if theoperator turns up the voltage by 10 percent, themachine automatically increases the preset voltagesat all the other wire feed speeds by 10 percent. Thepreset voltage, programmed at the factory, may bechanged with the wire feeder VOLTS adjustment.
The Arc Control adjusts the inductance. (This adjust-ment is often referred to as “pinch”. Inductance isinversely proportional to pinch.) Increasing the ArcControl setting decreases the inductance, whichresults in the arc getting colder and pinched tighter.Decreasing the Arc Control setting increases theinductance, which results in the arc getting wider(reduced pinch).
GMAW PULSE PROCEDURES
In these procedures, the actual voltage greatlydepends on the waveform used. The peak currents,background currents, rise times, fall times, and pulsetimes all affect the actual voltage. The actual voltagefor a given wire feed speed is not directly predictableunless the waveform is known. In this case, it is notpractical to preset an actual voltage for the procedure.Instead, an arc length adjustment is provided. Themachine “knows” what the best arc length is at thegiven wire feed speed but allows the operator tochange it.
POWER WAVE 455
B-6OPERATIONB-6
The arc length trim (usually referred to simply as“trim”) can be adjusted between 0.500 and 1.500 onthe control box’s Volts/Trim display. A Trim of 1.000means that no adjustments will be made to the presetarc lengths. A Trim greater than 1.000 increases thepreset arc lengths. A Trim setting less than 1.000decreases the preset arc lengths. The arc length trimadjustment is factored in at all wire feed speed set-tings. Increasing the Trim by 10 percent at a givenwire feed speed also increases all the other arc lengthtrim settings of the procedure by 10 percent.
The Power Wave utilizes a control scheme known asadaptive control in all pulse modes. Because thePower Wave utilizes adaptive control, it can adjust thepulsing parameters based on changes in the arc dueto changes in the electrical stickout of the electrode.(Electrical stickout is the distance from the contact toto the workpiece.) The Power Wave is optimizedfor use with a .75” stickout. The adaptive behavioris programmed to support a stickout range from .5” to1.25”. In the low and high end of the wire feed speedranges of most processes, the adaptive behavior maybe restricted. This is a physical restriction due toreaching the edge of the operating range for theprocess.
The Arc Control adjustment allows the pulse frequen-cy to be varied. Increasing the Arc Control causes thefrequency setting to increase, while decreasing theArc Control causes the frequency to decrease.Varying the Arc Control, and hence, the pulse fre-quency, affects the droplet transfer and allows fine-tuning for different welding positions.
CONSTANT CURRENT (CC/STICK, CC/TIG)PROCEDURES
Stick welding can be performed by choosing one ofthe stick welding modes. Check the Power Feed wirefeeder Operator’s Manual for instructions on how toenergize the output terminals on the Power Wave.(Certain options energize the terminals automaticallywhile other options require a manual adjustment toenergize the terminals.) The output current is set bythe Amps control on the Power Feed wire feeder. TheVolts/Trim adjustment has no effect in this mode.
The Arc Control adjusts the arc force. Increasing theArc Control setting increases the arc force, makingthe arc more harsh but less likely to stick. Decreasingthe Arc Control setting decreases the arc force, mak-ing the arc softer and smoother.
ARC GOUGING PROCEDURES
Arc gouging can be performed by choosing the arcgouging weld mode. Doing so automatically ener-gizes the output terminals on the Power Wave, mak-ing the power source immediately ready to weld. Theoutput current is set by the Amps control on thePower Weld wire feeder. The Volts/Trim adjustmenthas no effect in this mode.
