SAFETY

ELE CTRIC S HOCK 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 cl othing. Wear dry, hole-fre e

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 mu s t be per f orm e d unde r elec tric a lly ha zar d ous con ditions (in damp location s or whil e wear ing 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, elect rode reel, w elding head, nozzle or s emiauto matic 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. Ne ver simul ta neously tou ch e lectric al ly “ ho t” p ar ts o f 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.

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 g ases 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

we l ding w ith e lect rode s whi c h req u ire s pec i al ve n til atio n s uch as s tai nle s s or har d fac i ng (se e in str uct ion s on c ont ain er or MSDS ) or on lead or cadmi um plat ed stee l and othe r metal s or co atings which produce highly toxic fumes, keep exposure as low as possible and within applicable OSHA PEL and ACGIH TLV limits using local exhaust or mechanical ventilation. In c on fi ne d spaces or in s om e ci rc um st a nce s, out d oor s, a resp ira t or ma y be requ ire d . 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.

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

cause i nj ur y or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.

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

Re m embe r th a t we l din g spa r ks an d ho t materials from welding can easily go through small cracks an d ope nings t o adj ace nt ar eas . Avoid w eld ing nea r 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 Standar d Z49.1) and t he oper at ing i nformatio n 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 Co n tain ers and Pi pin g T h at Hav e H e ld Haz a rdo u s Substances”, AWS F4.1 from the American Welding Society

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 ma sse. Un cour t-circuit ac cidental p eut provoq uer 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, netto yage 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. Protég er l’autre pe rs on nel t ra va illant à pr ox im ité a u

soudage à l’aide d’écrans appropriés et non-inflammables.

4. De s g outte s 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.

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 manufacturer’s 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 manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains supply. Consideration should be given to shielding the supply cable of permanently installed 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 manufacturer’s 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 manufacturer’s 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 prob-

lems of interference. Screening of the entire welding installation may be considered for special applications.

Safety Precautions

WARNING

ELECTRIC SHOCK can kill.

• Only qualified personnel should perform this installation.

• Turn the input power OFF and unplug the machine from the receptacle before working on this equipment. Allow machine to sit for 5 min-

minimum to allow the power

utes capacitors to discharge before working inside this equipment.

•

Insulate yourself from the work and ground.

•

Always wear dry insulating gloves.

• Always connect the to a power supply grounded according to the National Electrical Code and local codes.

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

SELECT SUITABLE LOCATION

The Invertec® V311-T AC/DC TIG 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.

• The machine must be located where there is free cir-

culation of clean air such that air movement in the back and out the front will not be restricted.

• Dirt and dust that can be drawn into the machine

should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown.

STACKING

The Inverte c ® V311-T AC/DC TIG can stacked.

TILTING

Place the machine directly on a secure, level surface. The machine may topple over if this procedure is not followed.

ENVIRONMENTAL AREA

Keep the machine dry. Do not place it on wet ground or in puddles.

MACHINE GROUNDING AND HIGH FREQUENCY INTERFERENCE PROTECTION

The Capacitor Discharge Circuit used in the high frequency generator, may cause many radio, TV and electronic equipment interference problems. These problems may be the result of radiated interference. Proper grounding methods can reduce or eliminate radiated interference.

The Invertec® V311-T AC/DC TIG has been field tested under recommended installation conditions. It complies with FCC allowable limits for radiation.

Radiated interference can develop in the following four ways:

1. Direct interference radiated from the welder.

2. Direct interference radiated from the welding leads.

3. Direct interference radiated from feedback into the power lines.

4. Interference from re-radiation of “pickup” by ungrounded metallic objects.

Keeping these contributing factors in mind, installing equipment per the following instructions should minimize problems.

1. Keep the welder power supply lines as short as possible and enclose as much of them as possible in rigid metallic conduit or equivalent shielding for a distance of 50 feet (15.2m). There should be good electrical contact between this conduit and the welder case ground. Both ends of the conduit should be connected to a driven ground and the entire length should be continuous.

2. Keep the work and electrode leads as short as poss i b le and a s close together as p o s sible. Lengths should not exceed 25 ft (7.6m).

3. Be sure the torch and work cable rubber cover-

ings are free of cuts and cracks that allow high frequency leakage. Cables with high natural rubber content, such as Lincoln Stable-Arc resist high frequency leakage than neoprene and other synthetic rubber insulated cables.

4. Keep the torch in good repair and all connections

tight to reduce high frequency leakage.

better

INVERTEC® V311-T AC/DC TIG

5. The work terminal must be connected to a ground within ten feet of the welder, using one of the following methods.

a) A metal underground water pipe in direct con-

tact with the earth for ten feet or more.

b) A 3/4” (19mm) galvanize d p ipe or a 5 /8”

(16mm) solid galvanized iron, steel or copper rod driven at least eight feet into the ground.

The ground should be securely made and the grounding cable should be as short as possible using cable of the same size as the work cable, or larger. Grounding to the building frame electrical conduit or a long pipe system can result in re-radiation, effectively making these members radiating antennas.

6. Keep all panels securely in place.

7. All electrical conductors within 50 ft (15.2m) of the welder should be enclosed in grounded, rigid metallic conduit or equivalent shielding. Flexible metallic conduit is generally not suitable.

INSTALLATION

A-3

RECONNECT PROCEDURE

The Invertec® V311-T AC/DC auto reconnects to 208V, 230V or 460V supply.

Fuse the input circuit with time delay fuses or delay

type

circuit breakers. Using fuses or circuit breakers smaller than recommended may result in “nuisance” shut-offs from welder inrush currents even if not welding at high currents.

The Invertec® V311-T AC/DC is recommended for use on an individual branch circuit.

Also called “inverse time” or “thermal/magnetic” circuit breakers. These c ir cu it brea ke rs have a delay in t ri pp ing acti on that decreases as the magnitude of the current increases.

8. When the welder is enclosed in a metal building, several earth driven electrical grounds connected (as in 5b above) around the periphery of the building are recommended.

Failure to observe these recommended installation procedures can cause radio or TV interference problems.

INPUT CONNECTIONS

Be sure the voltage, phase, and frequency of the input power is as specified on the rating plate, located on the bottom of the machine.

DYNAMIC LCD DISPLAY

The Dynamic display is divided into several sections (Refer to Figure B.4):

1. Weld Sequence Diagram

B-4

2. Parameter Display

3. Mode Push Button Indicators

Figure B.4

1. The Weld Sequence Diagram shows the various

parameters that can be selected and adjusted and their pr ese t values. As the p ush button/rota ry encoder is pressed a triangular shaped flashing indicator will highlight the adjustable parameter on the sequence diagram in bold. Each press of the encoder will scroll to the next selected parameter sequentially. Rotating the push button encoder will change the selected parameter value. The display is dynamic in that adjusting the selected parameter dynamically changes the shape of the sequence diagram. After 5 seconds of inactivity the selected parameter will default back to the weld output amps par amete r. Depressin g the butt on a gain will remember the last selected parameter and begin the sequential scroll from that parameter.

Three Sequence Diagram types exist:

• STICK (See Figure B.4a)

• TIG (See Figure B.4b)

• Pulse TIG (See Figure B.4c)

Figure B.4b

Figure B.4c

2. The Parameter Display Section shows the select-

ed parameter its display icon and preset value. To ch ange the value, rotate the pus h b utton/r otary encoder. Some parameters like AC Frequency have an Enhanced Icon Display that shows the effect of the varying parameter on the arc and/or weld bead profile. As these parameters are adjusted an indicator will move between the minimum and maximum icon to show the relative effect of that parameter. Pulse Frequency shown in Figure B.4c is an example of the enhanced icon display. Refer to Table B.1 for a list of Enhanced Icons.

A. WELDING MODES

DC TIG - DC TIG welding with high frequency arc initiation.

AC TIG - AC TIG welding with high frequency arc initiation.

DC Touch Start TIG - DC TIG welding with lift tig arc initiation.

Stick crisp mode - for Cellulosic electrodes like Exx10.

Stick soft mode - for E7018 Low Hydrogen electrodes.

AC Stick Mode - for AC Stick Electrodes.

Table B.2

B. TIG TRIGGER MODES

Two Step with Arc Start Switch -

This mode is available in local or remote modes but is typically used with an arc start switch. Depressing the arc start switch will initiate the arc at the start current level and ramp up the output to the maximum current over the time set by the upslope time. Releasing the switch will cause the output amperage to ramp down to the finish current over the downslope time and then turn off the output. In this mode the start current and finish current can be independently set and upslope and downslope times are adjustable. (Refer to Figure B.5)

Two-Step with Foot Pedal -This mode i s only available w hen the machine senses a remote amperage control device is plugged in. It is used when a foot or hand ampt r o l is plugged in. When this trigger mode is selected, upslope and downslope are set to zero and non-adjustable since the operator would manually adjust ramp up and ramp down of the welding current using the amptrol. The start and finish currents are linked together and are repesented by a parameter called Minimum Current. (Refer to Figure B.5)

Four Step - This mode is intended to be used with an arc start switch. It will not function properly in remote mode with a foot or hand amptrol plugged in. In four step operation depressing an arc sta rt switch will cause the machine to initiate the arc at the start current level. When the switch is released the machine will ramp up to the maximum current over the upslope time. Depressing the arc start switch again causes the output to ramp down to the finish current level ov er the downsl ope time. Fin ally releasing the arc start switch causes the arc to go out. (Refer to Figure B.6)

INVERTEC® V311-T AC/DC TIG

Page 21

B-6

OPERATION

B-6

Bi-Level Current – (If Enabled from

the Setup Menu) Depressing an arc start switch and releasing will initiate the arc to current l e v e l A1 . De pressing and releasi ng the arc Start switch again will toggle to current level A2. Each depressing and releasing of the switch will toggle between A1 and A2. Depressing and holding the switch in will initiate the down slope to the finish current level and finally releasing the trigger will extinguish the arc.

Spot Timer - (If Enabled from the Setup Menu) Selecting this trigger mode will enable a spot timer parameter setting to be displayed as a welding parameter. Once the arc is establish the machine will weld for the time period set by the spot timer parameter setting. The machine will follow the functionality of two-step in that start current, up-slope, down-slope and finish current can all be adjusted.

STICK TRIGGER MODES

Local - In this mode the machine

ignores any remote that is plugged. The machine will weld at the preset value set at the panel of the machine.

Remote - Allows the amperage to be set with a remote potentiometer.

C. TIG PULSE MODES

Pulse On - Turns on pulse welding in

TIG mode. Changes the sequence diagram to Pulse TIG and allows the adjustment of the following added parameters:

• Pulse Frequency

• % Peak Time

• Background Current

Pulse Off - Turns off pulse welding in TIG.

D, E, & F. Memory Operation – Pressing and releasing the memory location (D) button will scroll through memory locations 1 through 10. When a memory is recalled or saved the memory location display will change to reversed text indicating that the current memory parameters are active.

Normal Display Reversed Display

(Unselected) (Selected)

Saving to Memory

• Press and hold Memory Save Button (E) until the memory location display indicator (D) changes to a reverse text indicating that the current parameters are the ones in the actively selected memory.

Recalling from Memory

• Press and hold the memory recall button (F) until the memory location display indicator (D) changes to reversed text indicating that the stored parameters are actively recalled.

When memory parameters are actively selected, the display indicator will remain reversed until a welding parameter is changed with the encoder knob or until the memory location button is pressed to scroll to a different memory location

Local/Remote Operation – The Invertec® V311-T AC/DC, when in TIG mode, will automatically sense when the machine has a remote device plugged into the 6 pin MS-type connector-like a remote pendant or a foot amptrol. If a remote device is plugged in, the machine will automatically function in remote mode. If no device is plugged in, the machine will function in local mode.

In remote mode, the operation of the machine is slightly different depending on whether the remote device is a foot amptrol or a remote pendant. To let the machine know what type of device is plugged in, the operator must select the appropriate device from the trigger mode button. (See Trigger mode descriptions above for details on the difference. In stick mode the second button on the control panel selects local or remote operation manually. This is required so that the user does not need to detach a foot amptrol to use the machine in STICK mode.

This function sets the initial start energy limit. Set this number to a higher setting than t he factory d e f ault if n e e d e d to improve starting of large diameter tungsten electrodes.

0.5 to 1.0 manual start energy setting.

1.2 to 5.0 = max. Incrementing limit. (See Note)

Note: The machine will try to start the arc at

a start power of 1. If the arc does not establish it will incrementally increase the start power and try to restrike up to the set limit.

OPTIONAL COOL-ARC 35 WATER COOLER

The optional Cool-Arc 35 water cooler is designed to operate in communication with the Invertec® V311-T AC/DC. Refer to the Cool-Arc 35 operator manual for installation instructions and a complete description of its operation.

When the Invertec® V311-T AC/DC is powered ON the Cool-Arc 35 will automatically power ON as well. The Cool-Arc 35 monitors pressure and temperature and will adjust the pump speed accordingly to cool the torch. If a blockage of coolant or loss of coolant is sensed both the Cool-Arc 35 and Invertec® V311-T AC/DC will display an error and turn off the Invertec® V311-T AC/DC’s output.

104

IMPORTANT: If the Cool-Arc 35 water cooler is connected to the Invertec® V311-T AC/DC and an air cooled torch is connected instead of a water cooled torch the Cool-Arc 35 will sense a coolant blockage resulting in a cooler error.

In this case the cooler can be turned to the “off mode” by depressing and holding the push button on the cooler until the cooler’s display reads “oo”. To turn the cooler back on you can depress and hold the Cool-Arc 35 push button until the cooler’s digital display reads coolant temperature in degrees Celsius. Turning the Invertec® V311-T AC/DC off and on again will automatically turn the water cooler back on as well.

TIPS FOR IMPROVED TIG STARTING

1. Start Current:

For the best AC or DC TIG starting characteristics it may be necessary to adjust the start current on the front panel depending on the tungsten size. In general, larger tungsten requires more energy to establish an arc than smaller tungsten. As an initial guideline, set the start current according to the following recommendations:

Tungsten Size (in.) Start Current (Amps)

0.020, 0.040 1/16th 6-10 Amps 3/32 th 10-12 Amps 1/8th 12-15 Amps

2. DC Strike Current:

Aside from start current, DC strike current can also be adjusted from the set-up menu to get a hotter or softer start when DC TIG welding. Strike current is an initial spike of current that lasts a few milliseconds before the machine goes to start current. In general, the factory default of 15 amps works for most applications. If welding on very thin materials with small diameter tungsten, strike current can be turned down to minimize burning through the weld material. Like-wise for larger diameter tungsten strike current can be turned up to put more energy in the tungsten.

If start power is set within the incremental range mode, the machine tries to start electrode positive at a relative setting of 1. If the arc fails to establish it will repeat the start sequence each time by incrementing the amount of electrode positive energy by 10% (0.1) up to the start power limit setting or until the arc establishes. For comparison a start power limit of 2 if reached will have twice the energy of the starting point of 1. If the tungsten has too much of a ball on it or appears to be super heating during starts the start power limit can be turned down. In the manual setting range, the start power will not keep incrementing up to a limit. Instead the start power stays at whatever level is set. For example a setting of 0.5 will start the machine with half the normal starting energy of 1.

STICK CRISP MODE DYNAMIC CURRENT REGULATION

When running E6010 electrodes DC Crisp mode is recommended. The Invertec® V311-T AC/DC has a special dynamic current regulation that is ideal for the whipping technique common to E6010 electrodes.The machine regulates the welding current based on changes in arc length. As the arc length is increased and the arc voltage increases, the machine will reduce its welding current below the set point. As the arc length is decreased and the arc voltage decreases the machine will increase its current.

FIGURE B.8

3. AC TIG Start Power:

For AC TIG welding AC start power can be adjusted from the set-up menu to aid starting if required. The Invertec® V311-T AC/DC when set to AC TIG will try to initiate the arc with positive polarity until the arc is established. Positive polarity puts more energy into heating the tungsten but the drawback is that is can cause the tungsten to ball excessively or to super heat. Note super heating of the tungsten can be noticed if the tungsten is glowing red or orange during starting. Start Power can be adjusted within two ranges:

Range Mode

0.5 to 1 Manual Setting

1.2 to 5.0 Incremental setting

Arc Force Control – Arc Force is a setting that helps reduce sticking the electrode into the weld puddle. Increasing the arc force percentage will provide a higher boost of current when the electrode is about to short into the weld puddle. In Stick Crisp mode since the current is dynamically regulated based on the arc voltage, shorting the electrode to the work will be rare

- therefore, adjustments to the arc force percentage will not be as noticeable in Stick Crisp mode compared to Stick Soft mode.
