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.

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.

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.

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

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.

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 manufacturerʼs instructions for this

equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employerʼs safety practices. MSDS forms are available from your welding distributor or from the manufacturer.

WELDING and CUTTING SPARKS can cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

Remember that welding sparks and hot 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.

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 LʼArc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à lʼélectrode 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 sʼisoler 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 lʼeau 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 sʼapplicuent aussi au pistolet de soudage.

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 nʼimporte quelle partie du corps.

3. Un coup dʼarc peut être plus sévère quʼun coup de soliel, donc:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi quʼun verre blanc afin de se protéger les yeux du rayonnement de lʼarc et des projections quand on soude ou quand on regarde lʼarc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de lʻarc.

c. Protéger lʼautre personnel travaillant à proximité au

soudage à lʼaide dʼécrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de lʼarc de soudage. Se protéger avec des vêtements de protection libres de lʼhuile, 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 lʼon pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque dʼincendie 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 dʼincendie.

8. Sʼassurer que la masse est connectée le plus prés possible de la zone de travail quʼil est pratique de le faire. Si on place la masse sur la charpente de la construction ou dʼautres 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 dʼincendie ou dʼechauffement des chaines et des câbles jusquʼà ce quʼils 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 dʼopérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de lʼarc 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.

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 lʼélectricité 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, Iʼinstallation et lʼentretien du poste seront effectués par un électricien qualifié.

3. Avant de faires des travaux à lʼinterieur de poste, la debrancher à lʼinterrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur place.

SAFETY

Electromagnetic Compatibility (EMC)

Conformance Products displaying the CE mark are in conformity with European Community Council Directive of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility (89/336/EEC). It was manufactured in conformity with a national standard that implements a harmonized standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment. It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.

Introduction All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions are received by other equipment, electrical interference may result. Electrical emissions may affect many kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions may be required when a welding power source is used in a domestic establishment.

Installation and Use The user is responsible for installing and using the welding equipment according to the manufacturerʼs instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases this remedial action may be as simple as earthing (grounding) the welding circuit, see Note. In other cases it could involve construction 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.

Note: The welding circuit may or may not be earthed for safety reasons according to national codes.

Changing the earthing arrangements should only be authorized by a person who is competent to access whether the changes will increase the risk of injury, e.g., by allowing parallel welding current return paths which may damage the earth circuits of other equipment.

Assessment of Area Before installing welding 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, signaling and telephone cables; above, below and adjacent to the

welding equipment;

b) radio and television transmitters and receivers;

c) computer and other control equipment;

d) safety critical equipment, e.g., guarding of industrial equipment;

e) the health of the people around, e.g., the use of pacemakers and hearing aids;

f) equipment used for calibration or measurement

g) the immunity of other equipment in the environment. The user shall ensure that other equipment being

used in the environment is compatible. This may require additional protection measures;

h) the time of day that welding or other activities are to be carried out.

SAFETY

Electromagnetic Compatibility (EMC)

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 Welding equipment should be connected to the mains supply according to the manufacturerʼs 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 welding equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The shielding should be connected to the welding power source so that good electrical contact is maintained between the conduit and the welding power source enclosure.

Maintenance of the Welding Equipment The welding equipment should be routinely maintained according to the manufacturerʼs recommendations. All access and service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding equipment should not be modified in any way except for those changes and adjustments covered in the manufacturers instructions. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and maintained according to the manufacturerʼs recommendations.

Welding Cables The welding cables should be kept as short as possible and should be positioned close together, running at or close to floor level.

Equipotential Bonding Bonding of all metallic components in the welding installation and adjacent to it should be considered. However, metallic components bonded to the work piece 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.

Earthing of the Workpiece Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size and position, e.g., ships 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 capacitance, selected according to national regulations.

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 welding installation may be considered for special applications. 1

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.

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

LOCATION AND MOUNTING

The POWER WAVE® i400 case is designed to support the Fanuc R30iA controller and op box (up to 300lbs), matching the controllerʼs footprint and styling. Mounting is externally accessible for simplified integration. The flexibility of the POWER WAVE® i400 also allows it to be operated as a stand alone unit. In either case, bolting the unit to the floor or a suitable platform is recommended to provide maximum stability.The minimum recommended clearance for chassis removal is 26” (66cm) from the rear of the machine as viewed from the output studs. See the Chassis Removal Procedure for additional information.

CAUTION

• DO NOT MOUNT 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 .06”(1.6mm) thick, which shall extend not less than 5.90”(150mm) beyond the equipment on all sides.

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

ENVIRONMENTAL CONSIDERATIONS

The POWER WAVE® i400 will operate in harsh environments. Even so, it is important that simple preventative measures are followed in order to assure long life and reliable operation.

A-3

• Dirt and dust that can be drawn into the POWER WAVE® i400 should be kept to a minimum. The use of air filters on the air intake is not recommended because normal air flow may be restricted. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown.

• Do not use the POWER WAVE® i400 in an outdoor environment. The power source should not be subjected to falling water, nor should any parts of it be submerged in water.

INPUT AND GROUNDING CONNECTIONS

A-4

Choose input and grounding wire size according to local or national electrical codes. Using input wire sizes, fuses or circuit breakers smaller than recommended may result in "nuisance" shut-offs from welder inrush currents, even if the machine is not being used at high currents.

Power Supply Connection for the Fanuc R30iA Controller

The POWER WAVE® i400 is equipped with a dedicated robot power terminal block (4TB) specifically designed to feed input power directly to the Fanuc R30iA controller through the power source rotary ON/OFF switch. The K2677-1 Integration kit provides the proper cable and installations instructions to make this connection.

MACHINE GROUNDING

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

INPUT CONNECTIONS

WARNING

ELECTRIC SHOCK can kill.

• 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 case back. Connect L1, L2, L3 and ground according to the input supply and ground connection decals located near the input power terminal block (1TB) and ground block inside of the rear input reconnect box.

WARNING

The POWER WAVE® i400 on/off switch is not intended as a service disconnect for this equipment. 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 access door of the machine. Failure to do so may result in bodily injury or death.

Do not attempt to back feed input power though the robot power terminal block (4TB) into the POWER WAVE® i400. This is not its intended purpose and may result in machine damage, bodily injury or death.

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

ELECTRODE AND WORK CONNECTIONS

Connect the electrode and work cables between the appropriate output studs of the POWER WAVE® i400 and the robot weld cell per the connection diagrams included in this document. Size and route the cables per the following.

• Most welding applications run with the electrode being positive (+). For those applications, connect the electrode cable between the wire drive feed plate and the positive (+) output stud on the power source. Connect a work lead from the negative (-) power source output stud to the work piece.

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

CAUTION

Negative electrode polarity operation WITHOUT use of a remote work sense lead (21) requires the Negative Electrode Polarity attribute to be set. See the Remote Sense Lead Specification section of this document for further details.

For additional Safety information regarding the electrode and work cable set-up, See the standard “SAFETY INFORMATION” located in the front of this Instruction Manual.

TABLE A.1

OUTPUT CABLE GUIDELINES

GENERAL GUIDELINES

• Select the appropriate size cables per the “Output Cable Guidelines” in Table A.1.

Excessive voltage drops caused by undersized welding cables and poor connections often result in unsatisfactory welding performance. Always use the largest welding cables (electrode and work) that are practical, and be sure all connections are clean and tight.

Note: Excessive heat in the weld circuit indicates

undersized cables and/or bad connections.

• Route all cables directly to the work and wire

feeder, avoid excessive lengths and do not coil excess cable. Route the electrode and work cables

in close proximity to one another to minimize the loop area and therefore the inductance of the weld circuit.

• Always weld in a direction away from the work

(ground) connection.

In Table A.1 are copper cable sizes recommended for different currents and duty cycles. Lengths stipulated are the distance from the welder to work and back to the welder again. Cable sizes are increased for greater lengths primarily for the purpose of minimizing cable drop.

CABLE INDUCTANCE, AND ITS EFFECTS ON WELDING

Excessive cable inductance will cause the welding performance to degrade. There are several factors that contribute to the overall inductance of the cabling system including cable size, and loop area. The loop area is defined by the separation distance between the electrode and work cables, and the overall welding loop length. The welding loop length is defined as the total of length of the electrode cable (A) + work cable (B) + work path (C) (see Figure A.2). To minimize inductance always use the appropriate size cables, and whenever possible, run the electrode and work cables in close proximity to one another to minimize the loop area. Since the most significant factor in cable inductance is the welding loop length, avoid excessive lengths and do not coil excess cable. For long work piece lengths, a sliding ground should be considered to keep the total welding loop length as short as possible.

FIGURE A.2

REMOTE SENSE LEAD CONNECTIONS

Voltage Sensing Overview

The best arc performance occurs when the POWER WAVE® i400 has accurate data about the arc conditions. Depending upon the process, inductance within the electrode and work cables can influence the voltage apparent at the studs of the welder, and have a dramatic effect on performance. Remote voltage sense leads are used to improve the accuracy of the arc voltage information supplied to the control pc board. Sense Lead Kits (K940-xx) are available for this purpose.

General Guidelines for Voltage Sense Leads

Sense leads should be attached as close to the weld as practical, and out of the weld current path when possible. In extremely sensitive applications it may be necessary to route cables that contain the sense leads away from the electrode and work welding cables.

Voltage sense leads requirements are based on the weld process as follows:

TABLE A.2

Process Electrode Voltage Work Voltage

Sensing (67 lead)

Sensing (21 lead)

GMAW 67 lead required 21 lead optional GMAW-P

67 lead required 21 lead optional

FCAW 67 lead required 21 lead optional GTAW

The electrode voltage sense lead (67) is automatically enabled by the weld process, and integral to the to the 14 pin wire feeder control cable (K1785).

The work voltage sense lead (21) is manually enabled, but overridden by constant current weld processes defined for stud sensing.

Negative polarity semi-automatic process operation WITHOUT use of a remote work sense lead (21) requires the Negative Electrode Polarity attribute to be set. This establishes which output stud the electrode voltage sense lead (67) will be referenced to.

Voltage sense at studs Voltage sense at studs

2 3 3 3

Electrode Voltage Sensing

The remote ELECTRODE sense lead (67) is built into the standard wire feeder control cable (K1785) and is always connected to the wire drive feed plate when a wire feeder is present. Enabling or disabling electrode voltage sensing is application specific, and automatically configured by the active weld mode.

The remote ELECTRODE sense lead (67) is also available in the remote Voltage Sense Connector for applications that do not use the standard wire feeder control cable (K1785). This can be easily accessed with the optional K940 Sense Lead kit.

CAUTION

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

WARNING

The POWER WAVE® i400 is configured at the factory to sense work voltage at the negative output stud (positive output polarity with remote Work Voltage Sensing disabled).

CAUTION

Negative electrode polarity operation WITHOUT use of a remote work sense lead (21) requires the Negative Electrode Polarity attribute to be set via the Fanuc Teach Pendant or with the Weld Manager Utility (included on the Power Wave Utilities and Service Navigator CDʼs or available at www.powerwavesoftware.com).

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

While most applications perform adequately by sensing the work voltage directly at the output stud, the use of a remote work voltage sense lead is recommended for optimal performance. The remote WORK sense lead (21) can be accessed through the four-pin voltage sense connector located on the control panel by using the K940 Sense Lead Kit. It must be attached to the work as close to the weld as practical, but out of the weld current path. For more information regarding the placement of remote work voltage sense leads, see the section entitled "Voltage Sensing Considerations for Multiple Arc Systems."

If a remote work voltage sense lead is used, it must be enabled through the Fanuc Teach Pendant or with the Weld Manager Utility (included on the Power Wave Utilities and Service Navigator CDʼs or available at www.powerwavesoftware.com).

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

Voltage Sensing Considerations for Multiple Arc Systems

Special care must be taken when more than one arc is welding simultaneously on a single part. Multiple arc applications do not necessarily dictate the use of remote work voltage sense leads, but they are strongly recommended.

If Sense Leads ARE NOT Used:

• Avoid common current paths. Current from adjacent arcs can induce voltage into each others current paths that can be misinterpreted by the power sources, and result in arc interference.

If Sense Leads ARE Used:

• Position the sense leads out of the path of the weld current. Especially any current paths com-

mon to adjacent arcs. Current from adjacent arcs can induce voltage into each others current paths that can be misinterpreted by the power sources, and result in arc interference.

FIGURE A.3

DIRECTION OF TRAVEL

POWER WAVE® i400

• For longitudinal applications, connect all work leads at one end of the weldment, and all of the work voltage sense leads at the opposite end of the weldment. Perform welding in the direction away from the work leads and toward the sense leads.

(See Figure A.3)

CONTROL CABLE CONNECTIONS

General Guidelines

Genuine Lincoln control cables should be used at all times (except where noted otherwise). Lincoln cables

are specifically designed for the communication and power needs of the POWER WAVE® / Power Feed systems. Most are designed to be connected end to end for ease of extension. Generally, it is recommended that the total length not exceed 100 ft. (30.5 m). The use of nonstandard cables, especially in lengths greater than 25 ft. (7.6 m), can lead to communication problems (system shutdowns), poor motor acceleration (poor arc starting), and low wire driving force (wire feeding problems). Always use the shortest length of control cable possible, and DO NOT coil excess cable.

Regarding cable placement, best results will be

CAUTION

obtained when control cables are routed separate from the weld cables. This minimizes the possibility of interference between the high currents flowing through the weld cables, and the low level signals in the control cables. These recommendations apply to all communication cables including ArcLink® and Ethernet connections.

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

COMMON EQUIPMENT CONNECTIONS

Connection Between Power Source and Wire Feeder (K1785 or K2709 Control Cable)

The 14 pin wire feeder control cable connects the power source to the wire drive. It contains all of the necessary signals to drive the motor and monitor the arc, including the motor power, tachometer, and arc voltage feedback signals. The wire feeder connection on the POWER WAVE® i400 is located on the recessed control panel above the output studs. Fanuc robot arms are equipped with internal cabling and provide a standard 14 pin MSstyle connection at the base of the robot, and near the wire feeder mount at the top of the arm. The K2709 series external dress cable is recommended for severe duty applications such as hard automation or for robot arms not equipped with an internal control cable. Best results will be obtained when control cables are routed separate from the weld cables, especially in long distance applications. Maximum cable length should not exceed 100ft(30.5m).

A-16

Connection Between Power Source and ArcLink®XT Compatible Controllers or Ethernet Networks. Newer

model controllers, such as the Fanuc R30iA, communicate via ArcLink®XT over an industrial Ethernet connection. To facilitate this, the Power Wave i400 is equipped with an IP67 rated ODVA compliant RJ-45 Ethernet connector, which is located on the recessed control panel above the output studs. A special access chute is provided above the Ethernet connection on the Power Wave i400 to accommodate seamless integration with the Fanuc R30iA controller. The K2677-1 Integration Kit includes a specially designed industrial rated Ethernet cable for this purpose.

It is highly recommended that all external Ethernet equipment (cables, switches, etc.), as defined by the connection diagrams, be obtained through the Lincoln Electric Automation Division. It is critical that all Ethernet cables external to either a conduit or an enclosure are solid conductor, shielded cat 5e cable, with a drain. The drain should be grounded at the source of transmission, such as a network switch or the Fanuc R30iA ground strip. Ethernet cables will achieve optimal performance levels at distances up to 25 feet. Special attention to layout may be required to support distances greater than 25 feet, including specialized network equipment. For best results, always route Ethernet cables away from weld cables, wire drive control cables, or any other current carrying device that can create a fluctuating magnetic field. For additional guidelines refer to industry standard documents for industrial Ethernet networks. Failure to follow these recommendations can result in an Ethernet connection failure during welding.

The ethernet port of the Power Wave i400 is factory configured with a dynamic IP address. This is required for seamless operation with the Fanuc R30iA controller.

Connection Between Power Source and ArcLink® Compatible Controllers (K1543 or K2683 ArcLink Control Cable)

Earlier model Fanuc controllers communicate via traditional ArcLink® over a standard 2 wire CAN based network. In these systems, the 5 pin ArcLink control cable connects the power source to the controller. The control cable consists of two power leads, one twisted pair for digital communication, and one lead for voltage sensing. The sense leads and power leads are typically unused in this application. The 5 pin ArcLink connection on the POWER WAVE® i400 is located on the recessed control panel above the output studs. The control cable is keyed and polarized to prevent improper connection. Best results will be obtained when control cables are routed separate from the weld cables, especially in long distance applications. The recommended combined length of the ArcLink control cable network should not exceed 200ft(61.0m).

POWER WAVE® i400

Connections Between Power Source and Optional DeviceNet PLC Controller. Hard Automation applica-

tions and some earlier model controllers may require DeviceNet connectivity to control the power source. DeviceNet can also be used to monitor welding data, and system status information. The optional K2780-1 DeviceNet Kit is available for this purpose. It includes a 5 pin DeviceNet sealed mini style receptacle that mounts on the recessed control panel of the Power Wave i400, above the output studs. The DeviceNet cable is keyed and polarized to prevent improper connection. For best results, route DeviceNet cables away from weld cables, wire drive control cables, or any other current carrying device that can create a fluctuating magnetic field. DeviceNet cables must be sourced locally by the customer. For additional guidelines refer to the “DeviceNet Cable Planning and Installation Manual” (Allen Bradley publication DN-

6.7.2).

The DeviceNet MAC ID and baud rate of the POWER WAVE® i400 can be configured with the Diagnostics Utility (included on the POWER WAVE® Utilities and Service Navigator CDʼs or available at www.powerwavesoftware.com).

OTHER SET-UP ISSUES

Selecting a Wire Drive and Setting the Wire Drive Gear Ratio. The POWER WAVE® i400 can accom-

modate a number of standard wire drives including the AutoDrive 4R90 (default) and PF-10R. The feeder control system must be configured for both the wire drive type and gear ratio (high or low speed range). This can be accomplished via the Fanuc Teach Pendant (V7.30p14 or later) or with the Weld Manager Utility (included on the Power Wave Utilities and Service Navigator CDʼs or available at www.powerwavesoftware.com).

Note:

COMMON WELDING PROCEDURES

MAKING A WELD 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.

WARNING

POWER WAVE® i400

Page 33

B-7

Choose the electrode material, electrode size, shielding gas, and process (GMAW, GMAW-P etc.) appropriate for the material to be welded.

Select the weld mode that best matches the desired welding process. The standard weld set shipped with the Power Wave i400 encompasses a wide range of common processes that will meet most needs. If a special weld mode is desired, contact the local Lincoln Electric sales representative.

To make a weld, the Power Wave i400 needs to know the desired welding parameters. The robot controller sends the parameters from the teach pendant (arc voltage, wire feed speed, UltimArcTM value, etc.), to the Power Wave i400 via the ArcLink® communication protocol over the control, Ethernet or optional DeviceNet cables.

OPERATION

BASIC WELDING CONTROLS

Weld Mode

Selecting a weld mode determines the output characteristics of the Power Wave i400 power source. Weld modes are developed with a specific electrode material, electrode size, and shielding gas. For a more complete description of the weld modes programmed into the Power Wave at the factory, refer to the Weld Set Reference Guide supplied with the machine or available at www.powerwavesoftware.com.

B-7

In non-synergic modes, the WFS control behaves like a conventional power source where WFS and voltage are independent adjustments. Therefore, to maintain proper arc characteristics, the operator must adjust the voltage to compensate for any changes made to the WFS.

Volts

In constant voltage modes (GMAW), this control adjusts the welding voltage.

Trim

In pulse synergic welding modes (GMAW-P), the Trim setting adjusts the arc length. Trim is adjustable from

0.50 to 1.50. 1.00 is the nominal setting and is a good starting point for most conditions.

Note:

The Power Wave i400 can also be configured to display Trim as a voltage value. This allows the operator to pre-set an approximate welding voltage rather than a unitless Trim value. The pre-set voltage is limited based on the process, and provides the same range of operation as the corresponding Trim value.

This alternate configuration is regionally enabled based on the robot controller software. Refer to the Fanuc documentation for manual configuration information.

Wire Feed Speed (WFS)

In synergic welding modes (GMAW, GMAW-P), WFS is the dominant control parameter. The user adjusts WFS according to factors such as wire size, penetration requirements, heat input, etc. The Power Wave then uses the WFS setting to adjust the voltage and current according to the information contained in the selected weld mode.

Note:

The Power Wave i400 can be configured to use amperage as the dominant control parameter instead of WFS for synergic welding modes. In this configuration the user adjusts amperage according to factors such as wire size, penetration requirements, heat input, etc. The Power Wave then uses the amperage setting to adjust the WFS and voltage according to the information contained in the selected weld mode.

This alternate configuration is regionally enabled based on the robot controller software. Refer to the Fanuc documentation for manual configuration information.

UltimArcTM

UltimArcTM allows the operator to vary the arc characteristics from “soft” to “crisp”. UltimArcTM is adjustable from –10.0 to +10.0 with a nominal setting of 0.0.

CONSTANT VOLTAGE WELDING

Synergic CV

In synergic welding modes, WFS is the dominant control parameter. For each wire feed speed, a corresponding voltage is programmed into the machine at the factory. The user adjusts WFS according to factors such as wire size, material thickness, penetration requirements, etc. The Power Wave i400 then uses the WFS setting to select the appropriate nominal voltage. The Power Wave i400 can also be configured to use amperage as the dominant control parameter. In this configuration the Power Wave i400 uses the amperage setting to select the appropriate WFS and nominal voltage. In either case, the user can adjust the voltage higher or lower to compensate for material condition or individual preference.

POWER WAVE® i400

Page 34

B-8

Non Synergic CV

In non-synergic modes, the machine behaves like a conventional power source. The 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.

UltimArcTM

UltimArcTM adjusts the apparent inductance of the wave shape. The UltimArcTM adjustment is similar to a “pinch” function in that it is inversely proportional to inductance. UltimArcTM is adjustable from –10.0 to +10.0 with a nominal setting of 0. Increasing UltimArcTM results in a crisper, hotter arc. Decreasing the UltimArcTM provides a softer, colder arc.

OPERATION

Pulse Welding

When pulse welding, the power source primarily regulates the arc current, not the arc voltage. During a pulsing cycle, arc current is regulated from a low background level to a high peak level and then back down to the low background level. The average arc voltage increases and decreases as the average arc current is increased or decreased. The peak current, back ground current, rise time, fall time and pulse frequency all affect the average voltage. Since the average voltage for a given wire feed speed can only be determined when all the pulsing waveform parameters are known, a unitless value called “trim” is used for adjusting the arc length.

B-8

Pulse welding modes are synergic; using wire feed speed as the main control parameter. As the wire feed speed is adjusted, the power source adjusts the waveform parameters to maintain good welding characteristics. The Power Wave i400 can also be configured to use amperage as the dominant control parameter. In this configuration, as the amperage is adjusted, the power source selects the appropriate wire feed speed, and adjusts the waveform parameters to maintain good welding characteristics. In either case, trim is used as a secondary control to change the arc length for material conditions or individual preference.

UltimArcTM adjusts the focus or shape of the arc. UltimArcTM is adjustable from -10.0 to +10.0 with a nominal setting of 0.0. Increasing the UltimArcTM increases the pulse frequency and background current while decreasing the peak current. This results in a tight, stiff arc used for high speed sheet metal welding. Decreasing the UltimArcTM decreases the pulse frequency and background current while increasing the peak current. This results in a soft arc good for out of position welding.

The Power Wave utilizes adaptive control to compensate for changes in the electrical stick-out (distance from the contact tip to the work piece) while welding. The Power Wave waveforms are optimized for a 5/8” to 3/4” stick out depending on the wire type and wire feed speed. The adaptive behavior supports a range of stick outs from approximately ½” to 1-1/4”. At low or high wire feed speeds, the adaptive range may be less due to physical limitations of the welding process.

Trim adjusts the arc length and ranges from 0.50 to

1.50 with a nominal value of 1.00. Increasing the trim

value increases the arc length. Decreasing the trim value decreases the arc length. Alternately, trim can be displayed as a quasi-voltage value. This allows the operator to pre-set an approximate welding voltage rather than a unitless trim value. The pre-set voltage is limited based on the process, and provides the same range of operation as the corresponding trim value.
