safety

1.h. To avoid scalding, do not remove the radiator pressure cap when the engine is hot.

ELECTRIC AND MAGNETIC FIELDS may 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. EM F fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding.

2.c. Exposure to EMF fields in welding may have other health effects which are now not known.

2.d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit:

2.d.1.

Route the electrode and work cables together - Secure them 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 and

work cables. If the electrode cable is on your right side, the work cable should also be on your right side.

___________________________________________________

1.g. To prevent accidentally starting gasoline engines while turning

the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate.

2.d.4. Connect the work cable to the workpiece as close as possible to the area being welded.

2.d.5. Do not work next to welding power source.

SAFETY

ELECTRIC SHOCK can kill.

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 bare skin 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 full area of physical contact with work and ground.

In addition to the normal safety precautions, if welding must be performed under electrically hazardous conditions (in damp locations or while wearing wet clothing; on metal structures such as floors, gratings or scaffolds; when in cramped positions such as sitting, kneeling or lying, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the 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 semiautomatic welding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should 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 and welding machine in good, safe operating condition. Replace damaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders.

3.i. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.

ARC RAYS can burn.

4.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.

4.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.

FUMES AND GASES can be dangerous.

5.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. When

welding with electrodes which require special ventilation such as stainless or hard facing (see instructions on container or MSDS) or 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.

5. b. The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits.

5.c.

Do not weld in locations near chlorinated hydrocarbon coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors form phosgene, a highly toxic gas, and other irritating products.

vapors

3.j. Also see Items 6.c. and 8.

5.d. Shielding gases used for arc welding can displace air and

cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.

5.e. 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. MSDS forms are available from your welding distributor or from the manufacturer.

5.f. Also see item 1.b.

WELDING SPARKS can cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

the welding sparks from starting a fire.

materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic 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 hazardous situations. Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1) and the operating information for the equipment being used.

6.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld 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 been “cleaned”. For information, purchase “Recommended Safe Practices for the Containers and Piping That Have Held Hazardous Substances”, AWS F4.1 from the American Welding Society

(see address above).

6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode.

Sparks and spatter are thrown from the welding arc. Wear oil

6.f. free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a welding area.

6.g. Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding 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.

6.h. Also see item 1.c.

Remember that welding sparks and hot

SAFETY

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.

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 zones où l’on pique le laitier.

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.

INSTALLATION

SAFETY PRECAUTIONS Read this

entire installation section before you start installation.

WARNING

ELECTRIC SHOCK can kill.

• Only qualified personnel should perform this installation.

• Turn the input power OFF at the

disconnect switch or fuse box before working on this equipment. Turn off the input power to any other equipment connected to the welding system at the disconnect switch or fuse box before working on the equipment.

A-2

LIFTING

Lift the machine by the lift bail only. The lift bail is designed to lift the power source only. Do not attempt to lift the Power Wave with accessories attached to it.

STACKING

Power Wave machines can be stacked to a maximum of 3 high.

CAUTION

The bottom machine must always be placed on a firm, secure, level surface. There is a danger of machines toppling over if this precaution is not taken.

• Do not touch electrically hot parts.

• Always connect the Power Wave grounding lug

(located inside the reconnect input access door) to a proper safety (Earth) ground.

----------------------------------------------------------

SELECT SUITABLE LOCATION

Do not use Power Waves in outdoor environments. The Power Wave power source should not be subjected to falling water, nor should any parts of it be submerged in water. Doing so may cause improper operation as well as pose a safety hazard. The best practice is to keep the machine in a dry, sheltered area.

Do not mount the Power Wave 455M over combustible surfaces. Where there is a combustible surface directly under stationary or fixed electrical equipment, that surface shall be covered with a steel plate at least .060" (1.6mm) thick, which shall extend not less than 5.90" (150mm) beyond the equipment on all sides.

Place the welder where clean cooling air can freely circulate in through the rear louvers and out through the case sides and bottom. Dirt, dust, or any foreign material that can be drawn into the welder should be kept at a minimum. Do not use air filters on the air intake because the air flow will be restricted. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdowns.

Machines are equipped with F.A.N. (fan as needed) circuitry. The fan runs whenever the output is enabled, whether under loaded or open circuit conditions. The fan also runs for a period of time (approximately 5 minutes) after the output is disabled, to ensure all components are properly cooled.

If desired, the F.A.N. feature can be disabled (causing the fan to run whenever the power source is on). To disable F.A.N., connect leads 444 and X3A together at the output of the solid state fan control relay, located on the back of the Control PC board enclosure. (See Wiring Diagram)

POWER WAVE 455M

MACHINE GROUNDING

The frame of the welder must be grounded. A ground terminal marked with the symbol is located inside the reconnect/input access door for this purpose. See your local and national electrical codes for proper grounding methods.

HIGH FREQUENCY PROTECTION

Locate the Power Wave away from radio controlled machinery.

CAUTION

The normal operation of the Power Wave may adversely affect the operation of RF controlled equipment, which may result in bodily injury or damage to the equipment.

INPUT CONNECTION

WARNING

Only a qualified electrician should connect the input leads to the Power Wave. Connections should be made in accordance with all local and national electrical codes and the

connection diagram located on the inside of the reconnect/input access door of the machine. Failure to do so may result in bodily injury or death.

-------------------------------------------------------------

Use a three-phase supply line. A 1.75 inch (45 mm) diameter access hole for the input supply is located on the upper left case back next to the input access door. Connect L1, L2, L3 and ground according to the Input Supply Connection Diagram decal located on the inside of the input access door or refer to Figure A.1 on the following page.

NOTE: Turn main input power to the machine OFF before performing connection procedure. Failure to

do so will result in damage to the machine.

INPUT FUSE AND SUPPLY WIRE CONSIDERATIONS

Refer to the Technical Specifications at the beginning of this Installation section for recommended fuse and wire 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 to local or national electrical codes. Using fuses or circuit breakers smaller than recommended may result in

ELECTRODE AND WORK CABLE CONNECTIONS

Connect a work lead of sufficient size and length (Per Table 1) between the proper output terminal on the power source and the work. Be sure the connection to the work makes tight metal-to-metal electrical contact. To avoid interference problems with other equipment and to achieve the best possible operation, route all cables directly to the work and wire feeder. Avoid excessive lengths and do not coil excess cable.

“nuisance” shut-offs from welder inrush currents, even if the machine is not being used at high currents.

Welders are shipped connected for the highest input voltage listed on the rating plate. To move this connection to a different input voltage, see the diagram

Minimum work and electrode cable sizes are as follows:

located on the inside of the input access door. If the main reconnect switch or link position is placed in the wrong position, the welder will not produce output power.

NOTE: K1796 coaxial welding cable is recommended to reduce the cable inductance in long cable lengths. This is especially important when Pulse welding up to 350 amps.

If the Auxiliary (A) lead is placed in the wrong position, there are two possible results. If the lead is placed in a position higher than the applied line voltage, the welder may not come on at all. If the Auxiliary (A) lead is placed in a position lower than the applied line voltage, the welder will not come on, and the two circuit breakers or fuses in the reconnect area will open. If this occurs, turn off the input voltage, properly connect the (A) lead, reset the breakers, and try again. For machines equipped with a fuse in the reconnect area, turn off the input voltage and replace the fuse with the spare fuse that is attached to the reconnect switch pin.

When using inverter type power sources like the Power Waves, use the largest welding (electrode and work) cables that are practical. At least 2/0 (67 mm2) copper wire - even if the average output current would not normally require it. When pulsing, the pulse current can reach very high levels. Voltage drops can become excessive, leading to poor welding characteristics, if undersized welding cables are used.

CABLE INDUCTANCE, AND ITS EFFECTS ON PULSE WELDING

For Pulse Welding processes, cable inductance will cause the welding performance to degrade. For the total welding loop length less than tional welding cables may be used without any effects on welding performance. For the total welding loop length greater than

50 ft.(15.24m)), the K1796 Coaxial

Welding Cables are recommended. The welding loop length is defined as the total of electrode cable length (A) + work cable length (B) + work length (C) (See Figure A.3).

CAUTION

Excessive voltage drops caused by poor work piece connections often result in unsatisfactory welding performance.

------------------------------------------------------------------------

NEGATIVE ELECTRODE POLARITY

When negative electrode polarity is required, such as in some Innershield applications, switch the output connections at the power source (electrode cable to the negative (-) stud, and work cable to the positive (+) stud).

WORK

For long work piece lengths, a sliding ground should be considered to keep the total welding loop length less than

SLIDING

WORK

Output connections on some Power Waves are made via 1/2-13 threaded output studs located beneath the spring loaded output cover at the bottom of the case front.

Most welding applications run with the electrode being positive (+). For those applications, connect the electrode cable between the wire feeder and the positive (+) output stud on the power source (located beneath the spring loaded output cover near the bottom of the case front). Connect the other end of the electrode cable to the wire drive feed plate. The electrode cable lug must be against the feed plate. Be sure the connection to the feed plate makes tight metal-to-metal electrical contact. The electrode cable should be sized according to the specifications given in the work cable connections section. Connect a work lead from the negative (-) power source output stud to the work piece. The work piece connection must be firm and secure, especially if pulse welding is planned.

When operating with electrode polarity negative the "Electrode Sense Polarity" DIP switch must be set to the "Negative" position on the Wire Drive Feed Head PC Board. The default setting of the switch is positive electrode polarity. Consult the Power Feed instruction manual for further details.

VOLTAGE SENSING

The best arc performance occurs when the Power Waves have accurate data about the arc conditions. Depending upon the process, inductance within the electrode and work lead cables can influence the apparent voltage at the studs of the welder. Voltage sense leads improve the accuracy of the arc conditions and can have a dramatic effect on performance. Sense Lead Kits (K940-10, -25 or -50) are available for this purpose.

CAUTION

If the voltage sensing is enabled but the sense leads are missing, improperly connected, or if the electrode polarity switch is improperly configured, extremely high welding outputs may occur.

------------------------------------------------------------------------

The ELECTRODE sense lead (67) is built into the control cable, and is automatically enabled for all semiautomatic processes. The WORK sense lead (21) connects to the Power Wave at the four pin connector located underneath the output stud cover. By default the WORK voltage is monitored at the output stud in the Power Wave 455M. For more information on the WORK sense lead (21), see "Work Voltage Sensing” in the following paragraph.

All constant current processes sense the voltage at the output studs of the POWER WAVE-455M by default.

WARNING

• Do not touch electrically live parts or electrodes with your skin or wet clothing.

• Insulate yourself from the work and ground.

• Always wear dry insulating gloves.

Electrode Voltage Sensing

Enabling or disabling electrode voltage sensing is automatically configured through software. The 67 electrode sense lead is internal to the cable to the wire feeder and always connected when a wire feeder is present.

CAUTION

Important: The electrode polarity must be configured at the feed head for all semi-automatic processes. Failure to do so may result in extremely high welding outputs.

------------------------------------------------------------------------

POWER WAVE TO SEMI-AUTOMATIC POWER FEED WIRE FEEDER INTERCONNECTIONS

The Power Wave 455M and semi-automatic POWER FEED family communicate via a 5 conductor control cable (K1543). The control cable consists of two power leads, one twisted pair for digital communication, and one lead for voltage sensing. The cables are designed to be connected end to end for ease of extension. The output receptacle on the Power Wave 455M is located beneath the spring loaded output cover at the bottom of the case front. The input receptacle on the Power Feed is typically located at the back of the feeder, or on the bottom of the user interface.

For convenience sake, the electrode and control cables can be routed behind the left or right strain reliefs (under the spring loaded output cover), and along the channels formed into the base of the Power Wave, out the back of the channels, and then to the wire feeder.

-----------------------------------------------------------

1. Turn off power to the power source at the disconnect switch.

2. Remove the front cover from the power source.

3. The control board is on the left side of the power source. Locate the 8-position DIP switch and look for switch 8 of the DIP switch.

4. Using a pencil or other small object, slide the switch right to the OFF position if the work sense lead is NOT connected. Conversely, slide the switch to the ON position if the work sense lead is present.

5. Replace the cover and screws. The PC board will “read” the switch at power up, and configure the work voltage sense lead appropriately.

POWER WAVE 455M

Due to the flexibility of the platform the configuration may vary. The following is a general description of the system.

SYSTEM DESCRIPTION

The Power Wave 455M and Power Feed M family of products utilize a digital communication system called ArcLink. Simply put, ArcLink allows large amounts of information to be passed at very high speeds between components (nodes) in the system. The system requires only two wires for communication, and because of its bus-like structure, the components may be connected to the network in any order, thus simplifying the system setup.

Each "system" must contain only one power source. The number of wire feeders is determined by the type of wire feeder. Refer to the wire feeder instruction manual for details

WELDING WITH MULTIPLE POWER WAVES

CAUTION

Special care must be taken when more than one Power Wave is welding simultaneously on a single part. Arc blow and arc interference may occur or be magnified.

------------------------------------------------------------------------

Each power source requires a work lead from the work stud to the welding fixture. Do not combine all of the work leads into one lead. The welding travel directions should be in the direction moving away from the work lead as shown below. Connect all of the work sense leads from each power source to the work piece at the end of the weld.

For the best results when pulse welding, set the wire size and wire feed speed the same for all the Power Waves. When these parameters are identical, the pulsing frequency will be the same, helping to stabilize the arcs.

CONTROL CABLE SPECIFICATIONS

It is recommended that genuine Lincoln control cables be used at all times. Lincoln cables are specifically designed for the communication and power needs of the Power Wave / Power Feed system.

CAUTION

The use of non-standard cables, especially in lengths greater than 25 ft.(7.62), can lead to communication problems (system shutdowns), poor motor acceleration (poor arc starting) and low wire driving force (wire feeding problems).

-----------------------------------------------------------------------The K1543 series of control cables can be connected end to end for ease of extension. Do not exceed more

than 100 feet (30.5 m) total control cable length.

Every welding gun requires a separate shielding gas regulator for proper flow rate and shielding gas coverage.

Do not attempt to supply shielding gas for two or more guns from only one regulator.

If an anti-spatter system is in use then each gun must have its own anti-spatter system. (See Figure A.2)

(See Figure A.6 for Dual Head Boom Feeder)

WATER FLOW SENSOR

Water cooled guns can be damaged very quickly if they are used even momentarily without water flowing. A water flow sensor is recommended for those water coolers that do not have an integral flow sensor. Recommended practice is to install a water flow sensor such as K1536-1 on the water return line of the torch. When fully integrated into the welding system, the sensor will prevent welding if no water flow is present.

OPERATION

GENERAL DESCRIPTION

The Power Wave semi-automatic power source is designed to be a part of a modular, multi-process welding system. Depending on configuration, it can support constant current, constant voltage, and pulse welding modes.

The Power Wave power source is designed to be used with the semi automatic family of Power Feed wire feeders, operating as a system. Each component in the system has special circuitry to "talk with" the other system components, so each component (power source, wire feeder, user interface) knows what the other is doing at all times. These components communicate with ArcLink

The Power Wave 455M is a high performance, digitally controlled inverter welding power source capable of complex, high-speed waveform control. Properly equipped, it can support the GMAW, GMAW-P, FCAW, SMAW, GTAW, and CAC processes. It carries an output rating of either 450 amps, 38 volts; or 400 amps, 36 volts (both at 100% duty cycle), depending on input voltage and frequency.

RECOMMENDED PROCESSES AND EQUIPMENT

RECOMMENDED PROCESSES

The Power Wave 455M can be set up in a number of configurations, some requiring optional equipment or welding programs. Each machine is factory preprogrammed with multiple welding procedures, typically including GMAW, GMAW-P, FCAW, GTAW, and CAC for a variety of materials, including mild steel, stainless steel, cored wires, and aluminum.

The Power Wave 455M is recommended for semiautomatic welding with ArcLink compatible equipment like the Power Feed M series of feeders. The Power Wave 455M can have a number of modules installed that allow the machine to be used in Robotic and hard automation applications.

Wire Drive Interface Module

For Robotic platforms the Wire Drive Control Module is required to drive the PF-10R wire drive. This module can be factory installed on K2202-3 or field installed for robotic applications.

The Wire Drive Control Module is also be equipped with a terminal strip for making simple input signal connections. It can be used to externally control the basic wire drive function. It is divided into three groups: Trigger group, Cold Inch group, and Shutdown group.

DeviceNet Interface Module

This module can be used for DeviceNet capability. It will has a 5 pin sealed mini connector per ANSI B93.55M-1981.

EtherNet/DeviceNet Module

This module includes the DeviceNet and EtherNet capability. The DeviceNet uses a 5 pin sealed mini connector per ANSI B93.55M-1981. The EtherNet uses a RJ5 connector.

RECOMMENDED EQUIPMENT

Power Wave 455M – Semi-Automatic Operation

Semi Automatic Power Waves can only be used with ArcLink compatible Power Feed semi-automatic wire feeders and modules. In addition, the Power Feed semi-automatic wire feeders may require optional equipment to access certain weld modes in the Power Wave. Other models of Lincoln feeders, or any models of non-Lincoln wire feeders, cannot be used.

All welding programs and procedures are selected through the Power Feed M semi-automatic user interface

REQUIRED EQUIPMENT

Any ArcLink compatible semi-automatic wire feeding equipment. Specifically, the semi-automatic Power Feed M family.

LIMITATIONS

WARNING

• The Power Waves are not to be used in outdoor environments.

------------------------------------------------------------------------

• Only ArcLink compatible Power Feed semi-automatic wire feeders and users interfaces may be used. Other Lincoln wire feeders or non-Lincoln wire feeders cannot be used.

• Power Wave 455M Output Limitations

The Power Wave 455M will support maximum average output current of 570 Amps (@ 60% duty cycle) on the standard Power Wave stud.

DUTY CYCLE AND TIME PERIOD

The Power Feed wire feeders are capable of welding at a 100% duty cycle (continuous welding). The power source will be the limiting factor in determining system duty cycle capability. Note that the duty cycle is based upon a ten minute period. A 60% duty cycle represents 6 minutes of welding and 4 minutes of idling in a ten minute period.

NOMINAL PROCEDURES

The Power Wave is designed to operate with 3/4" electrode stick-out for CV and Pulse processes.

FRINGE PROCEDURES

Excessively short or long electrode stick-outs may function only on a limited basis, if at all.

MAKING A WELD

WARNING

The serviceability of a product or structure utilizing the welding programs is and must be the sole responsibility of the builder/user. Many variables beyond the control of The Lincoln Electric Company affect the results obtained in applying these programs. These variables include, but are not limited to, welding procedure, plate chemistry and temperature, weldment design, fabrication methods and service requirements. The available range of a welding program may not be suitable for all applications, and the build/user is and must be solely responsible for welding program selection.

------------------------------------------------------------------------

The steps for operating the Power Wave will vary depending upon the options installed in the user interface (control box) of the welding system. The flexibility of the Power Wave system lets the user customize operation for the best performance.

First, consider the desired welding process and the part to be welded. Choose an electrode material, diameter, shielding gas and process (GMAW, GMAWP, etc.)

Second, find the program in the welding software that best matches the desired welding process. The standard software shipped with the Power Waves encompasses a wide range of common processes and will meet most needs. If a special welding program is desired, contact the local Lincoln Electric sales representative.

WELDING ADJUSTMENTS

All adjustments are made on the system component known as the User Interface (Control Box), which contains the switches, knobs, and digital displays necessary to control both the Power Wave and a Power Feed wire feeder. Typically, the Control Box is supplied as part of the wire feeder. It can be mounted directly on the wire feeder itself, the front of the power source, or mounted separately, as might be done in a welding boom installation.

Because the Control Box can be configured with many different options, your system may not have all of the following adjustments. Regardless of availability, all controls are described below. For further information, consult the Power Feed wire feeder instruction manual.

• WFS / AMPS:

In synergic welding modes (synergic CV, pulse GMAW) WFS (wire feed speed) is the dominant control parameter, controlling all other variables. The user adjusts WFS according to factors such as weld size, penetration requirements, heat input, etc. The Power Wave then uses the WFS setting to adjust its output characteristics (output voltage, output current) according to pre-programmed settings contained in the Power Wave 455M. In non-synergic modes, the WFS control behaves more like a conventional CV power source where WFS and voltage are independent adjustments. Therefore to maintain the arc characteristics, the operator must adjust the voltage to compensate for any changes made to the WFS.

In constant current modes (stick, TIG) this control adjusts the output current, in amps.

• VOLTS / TRIM:

In constant voltage modes (synergic CV, standard CV) the control adjusts the welding voltage.

In pulse synergic welding modes (pulse GMAW only) the user can change the Trim setting to adjust the arc length. It is adjustable from 0.500 to 1.500. A Trim setting of 1.000 is a good starting point for most conditions.

To make a weld, the Power Wave needs to know the desired welding parameters. The Power Feed (PF) family of feeders communicate settings to the Power Wave through control cable connection. Arc length, wire feed speed, arc control, etc. are all communicated digitally via the control cable.

OPERATION

• 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 a welding mode determines the output characteristics of the Power Wave power source. For a more complete description of the welding modes available in the Power Wave, see the explanation below.

• ARC CONTROL

Also known as Inductance or Wave Control. Allows operator 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 (The nominal setting of 00.0 may be displayed as OFF on some Power Feed wire feeder control panels). See the Welding Mode descriptions, below, for detailed explanations of how the Arc Control affects each mode.

CONSTANT VOLTAGE WELDING

Synergic CV:

For each wire feed speed, a corresponding voltage is preprogrammed into the machine through special software at the factory. The nominal preprogrammed voltage is the best average voltage for a given wire feed speed, but may be adjusted to preference. When the wire feed speed changes, the Power Wave automatically adjusts the voltage level correspondingly to maintain similar arc characteristics throughout the WFS range.

FIGURE A.5

Non Synergic CV:

This type of CV mode behaves more like a conventional CV power source. Voltage and WFS are independent adjustments. Therefore to maintain the arc characteristics, the operator must adjust the voltage to compensate for any changes made to the WFS.

All CV Modes:

Arc Control, often referred to as wave control, adjusts the inductance of the wave shape. The wave control adjustment is similar to the "pinch" function in that it is inversely proportional to inductance. Therefore, increasing wave control greater than 0.0 results in a harsher, colder arc while decreasing the wave control to less than 0.0 provides a softer, hotter arc. (See Figure A.5)

OPERATION

PULSE WELDING

Pulse welding procedures are set by controlling an overall "arc length" variable. When pulse welding, the arc voltage is highly dependent upon the waveform. The peak current, back ground current, rise time, fall time and pulse frequency all affect the voltage. The exact voltage for a given wire feed speed can only be predicted when all the pulsing waveform parameters are known. Using a preset voltage becomes impractical, and instead the arc length is set by adjusting "trim".

Trim adjusts the arc length and ranges from 0.50 to

1.50, with a nominal value of 1.00. Trim values greater than 1.00 increase the arc length, while values less than 1.00 decrease the arc length.

Most pulse welding programs are synergic. As the wire feed speed is adjusted, the Power Wave will automatically recalculate the waveform parameters to maintain similar arc properties.

FIGURE A.6

The Power Wave utilizes "adaptive control" to compensate for changes in electrical stick-out while welding. (Electrical stick-out is the distance from the contact tip to the work piece.) The Power Wave waveforms are optimized for a 0.75" (19mm) stick-out. The adaptive behavior supports a range of stickouts from

0.50" (13mm) to 1.25" (32mm). At very low or high wire feed speeds, the adaptive range may be less due to reaching physical limitations of the welding process.

Arc Control, often referred to as wave control, in pulse programs usually adjusts the focus or shape of the arc. Wave control values greater than 0.0 increase the pulse frequency while decreasing the background current, resulting in a tight, stiff arc best for high speed sheet metal welding. Wave control values less than

0.0 decrease the pulse frequency while increasing the background current, for a soft arc good for out-of-position welding. (See Figure A.6)

SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

• Only Qualified personnel should perform this maintenance.

• Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.

• Do not touch electrically hot parts.

ROUTINE MAINTENANCE

Routine maintenance consists of periodically blowing out the machine, using a low pressure airstream, to remove accumulated dust and dirt from the intake and outlet louvers, and the cooling channels in the

machine.

D-1

PERIODIC MAINTENANCE

Calibration of the Power Wave 455M is critical to its operation. Generally speaking the calibration will not need adjustment. However, neglected or improperly calibrated machines may not yield satisfactory weld performance. To ensure optimal performance, the calibration of output Voltage and Current should be

checked yearly.

CALIBRATION SPECIFICATION

Output Voltage and Current are calibrated at the factory. Generally speaking the machine calibration will not need adjustment. However, if the weld performance changes, or the yearly calibration check reveals a problem, contact the Lincoln Electric Company for the calibration software utility.

The calibration procedure itself requires the use of a grid, and certified actual meters for voltage and current. The accuracy of the calibration will be directly affected by the accuracy of the measuring equipment you use. Detailed instructions are available with the utility.

TROUBLESHOOTING

USING THE STATUS LED TO TROUBLESHOOT SYSTEM PROBLEMS

The Power Wave / Power Feed are best diagnosed as a system. Each component (power source, user interface, and feed head) has a status light, and when a problem occurs it is important to note the condition of each. In addition, errors displayed on the user interface in most cases indicate only that a problem exists in the power source, not what the problem may be.

Therefore, prior to cycling power to the system, check the power source status light for error sequences as noted below. This is especially important if the user interface displays "Err 006" or "Err 100" .

Included in this section is information about the power source Status LED, and some basic troubleshooting

E-2

charts for both machine and weld performance. The STATUS LIGHT is a two color light that indicates system errors. Normal operation is a steady green light. Error conditions are indicated in the following chart.

LIGHT CONDITION

Status LED is solid green (no blinking).

Status LED is blinking green.

Status LED is blinking red and green.

Status LED is solid red (no blinking).

MEANING

1. System OK. Power source communicating normally with wire feeder and its components.

2. Occurs during a reset, and indicates the Power Wave 455M is mapping (identifying) each component in the system. Normal for first 1-10 seconds after power is turned on, or if the system configuration is changed during operation.

3. Non-recoverable system fault. If the PS Status light is flashing any combination of red and green, errors are present in the Power Wave 455M. Read the

error code before the machine is turned off.

To clear the error, turn power source off, and back on to reset.

Non recoverable hardware fault. Generally indicates nothing is connected to the Power Wave 455M wire feeder receptacle. See Trouble Shooting Section.

ERROR CODES FOR THE POWERWAVE

The following is a list of possible error codes that the Power Wave 455M can output via the status light (see "Troubleshooting the Power Wave / Power Feed System Using the Status LED." If connected to a PF-10/11 these error codes will generally be accompanied by an "Err 006" or "Err 100" on the user interface display.

Error Code #

11 CAN communication bus off. 12 User Interface time out error.

21 Unprogrammed Weld Mode.

22 Empty Weld Table.

23 Weld Table checksum error.

31 Primary overcurrent error.

32 Capacitor "A" under voltage

(Left side facing machine)

33 Capacitor "B" under voltage

(Right side facing machine)

34 Capacitor "A" over voltage

(Left side facing machine)

35 Capacitor "B" over voltage

(Right side facing machine)

Indication

Probably due to excessive number of communication errors. UI is no longer responding to the Power Source. The most likely cause is a fault/bad connection in the communication leads or control cable.

Contact the Service Department for instructions on reloading the Welding Software. Contact the Service Department for instructions on reloading the Welding Software. Contact the Service Department for instructions on reloading the Welding Software. Excessive Primary current present. May be related to a short in the main transformer or output rectifier. Low voltage on the main capacitors. May be caused by improper input configuration. When accompanied by an overvoltage error on the same side, it indicates no capacitor voltage present on that side, and is usually the result of an open or short in the primary side of the machine. Excess voltage on the main capacitors. May be caused by improper input configuration.

When accompanied by an under voltage error on the same side, it indicates no capacitor voltage present on that side, and is usually the result of an open or short in the primary side of the machine.

36 Thermal error

37 Soft start error

41 Secondary overcurrent error

43 Capacitor delta error

49 Single phase error

Other

Indicates over temperature. Usually accompanied by Thermal LED. Check fan operation. Be sure process does not exceed duty cycle limit of the machine.

Capacitor precharge failed. Usually accompanied by codes 32-35. The secondary (weld) current limit has been exceeded. When this occurs the machine output will phase back to 100 amps, typically resulting in a condition referred to as "noodle welding"

NOTE: The secondary limit is 570 amps for the standard stud, and 325 amps for all single phase operation.

The maximum voltage difference between the main capacitors has been exceeded. May be accompanied by errors 32-35.

Indicates machine is running on single phase input power. Usually caused by the loss of the middle leg (L2). Error codes that contain three or four digits are defined as fatal

errors. These codes generally indicate internal errors on the PS Control Board. If cycling the input power on the machine does not clear the error, try reloading the operating system. If this fails, replace the control board.

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.
