BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE

PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

WARNING

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. EMF 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.

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.

1.h. To avoid scalding, do not remove the

radiator pressure cap when the engine is

hot.

CALIFORNIA PROPOSITION 65 WARNINGS

SAFETY

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.

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.

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

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 within applicable OSHA PEL and

ACGIH TLV limits using local exhaust or mechanical

ventilation. In confined spaces or in some circum-

stances, 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 spe-

cific 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

vapors

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 prod-

ucts.

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.

SAFETY

iii

FOR ELECTRICALLY

powered equipment.

8.a. Turn off input power using the disconnect

switch at the fuse box before working on

the equipment.

8.b. Install equipment in accordance with the U.S. National

Electrical Code, all local codes and the manufacturer’s

recommendations.

8.c. Ground the equipment in accordance with the U.S. National

Electrical Code and the manufacturer’s recommendations.

CYLINDER may explode

if damaged.

7.a. Use only compressed gas cylinders

containing the correct shielding gas for the

process used and properly operating

regulators designed for the gas and

pressure used. All hoses, fittings, etc. should be suitable for

the application and maintained in good condition.

7.b. Always keep cylinders in an upright position securely

chained to an undercarriage or fixed support.

7.c. Cylinders should be located:

• Away from areas where they may be struck or subjected to

physical damage.

• A safe distance from arc welding or cutting operations and

any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any other

electrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outlet

when opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand

tight except when the cylinder is in use or connected for

use.

7.g. Read and follow the instructions on compressed gas

cylinders, associated equipment, and CGA publication P-l,

“Precautions for Safe Handling of Compressed Gases in

Cylinders,” available from the Compressed Gas Association

1235 Jefferson Davis Highway, Arlington, VA 22202.

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

the welding sparks from starting a fire.

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

though

they have

been “cleaned”. For information, purchase “Recommended

Safe Practices for the

Preparation

for Welding and Cutting of

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.

6.f.

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

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 cir-

cuits. This can create fire hazards or overheat lifting chains

or cables until they fail.

6.h. Also see item 1.c.

6.I. Read and follow NFPA 51B “ Standard for Fire Prevention

During Welding, Cutting and Other Hot Work”, available

from NFPA, 1 Batterymarch Park, PO box 9101, Quincy, Ma

022690-9101.

6.j. Do not use a welding power source for pipe thawing.

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 suiv-

antes:

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 ray-

onnement 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, pan-

talons 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 lev-

age, 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 debranch-

er 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 15 Dec

2004 on the approximation of the laws of the Member States relating to electromagnetic compatibility,

2004/108/EC. 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.

WARNING: This equipment is not intended for use in residential locations where the electrical power is pro-

vided by the public low-voltage supply system. There may be potential difficulties in ensuring electromagnet-

ic compatibility in those locations, due to conducted as well as radiated disturbances.

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 of 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. Follow your local and

national standards for installation and use. Changing the earthing arrangements should only

be authorized by a person who is competent to assess 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 prob-

lems 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

Public Supply System

Welding equipment should be connected to the public supply system according to the manufacturer’s rec-

ommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of

the public supply system. 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 equip-

ment 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, nor connected to earth because of its size

and position, e.g., ship’s 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 connec-

tion 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 applica-

tions1.

MACHINE GROUNDING AND HIGH FRE-

QUENCY INTERFERENCE PROTECTION

The Capacitor Discharge Circuit used in the high fre-

quency 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 test-

ed under recommended installation conditions. It com-

plies 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 mini-

mize 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

possible and as close together as possible.

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 rub-

ber content, such as Lincoln Stable-Arc®better

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.

Read entire installation section before starting

installation.

Safety Precautions

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

SELECT SUITABLE LOCATION

The Invertec® V311-T AC/DC TIG will operate in

harsh environments. Even so, it is important that sim-

ple 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 Invertec® V311-T AC/DC TIG can not be

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.

ELECTRIC SHOCK can kill.

• Only qualified personnel should per-

form this installation.

• Turn the input power OFF and

unplug the machine from the recep-

tacle before working on this equip-

ment. Allow machine to sit for 5 min-

utes

minimum to allow the power

capacitors to discharge before

working inside this equipment.

•

Insulate yourself from the work and ground.

•

Always wear dry insulating gloves.

• Always connect the

Invertec®

V311-T

AC/DC TIG

to a power supply grounded according to the

National Electrical Code and local codes.

WARNING

A-3

INSTALLATION

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 fol-

lowing methods.

a) A metal underground water pipe in direct con-

tact with the earth for ten feet or more.

b) A 3/4” (19mm) galvanized pipe 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-radi-

ation, 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.

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 build-

ing are recommended.

Failure to observe these recommended installation

procedures can cause radio or TV interference prob-

lems.

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

type1circuit breakers. Using fuses or circuit breakers

smaller than recommended may result in “nuisance”

shut-offs from welder inrush currents even if not weld-

ing at high currents.

The Invertec® V311-T AC/DC is recommended for

use on an individual branch circuit.

¹ Also called “inverse time” or “thermal/magnetic” circuit breakers.

These circuit breakers have a delay in tripping action that

decreases as the magnitude of the current increases.

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.

ELECTRIC SHOCK can kill.

• Have a qualified electrician install

and service this equipment.

• Turn the input power OFF and unplug

the machine from the receptacle

before working on this equipment.

• Allow machine to sit for 5 minutes

minimum to

allow the power capacitors to discharge before

working inside this equipment.

• Do not touch electrically hot parts.

• Machine must be plugged into a receptacle that

is grounded according to the National Electrical

Code and local codes.

• Do not remove or defeat the purpose of the

power cord ground pin.

GENERAL DESCRIPTION

The Invertec® V311-T AC/DC is an industrial 310 amp

arc welding power source that utilizes single or three

phase input power, to produce constant current out-

put. The welding response has been optimized for

stick (SMAW) and TIG (GTAW). The unit is ideal for

industrial applications where portability, high efficiency

and premium arc performance is important.

The Invertec® V311-T AC/DC is a power source that

can perform the following types of welding with excel-

lent results:

• TIG AC with square, sinusoidal and triangular

waveforms.

• TIG DC (with high frequency or Touch Start TIG

Starting)

• Stick DC & Stick AC

The Invertec® V311-T AC/DC is rated at 310 amps,

22.4 volts, at 40% duty cycle on a ten minute basis

when connected to a 460V three phase supply line. It

is capable of higher duty cycles at lower output cur-

rents. If the duty cycle is exceeded, a thermal protec-

tor will shut off the output until the machine cools. See

Technical Specifications in A-1 for other rated outputs.

The Invertec® V311-T AC/DC is recommended for

stick welding with such popular electrodes as

Fleetweld 5P and 5P+ (E6010), Fleetweld 35 (E6011),

a. VRD On (Voltage Reduction Device)

Status Light- Voltage reduction device can

be enabled from the set-up menu so that an

output voltage limit can be set that reduces

the output open circuit voltage to a safer level

when not welding. If enabled when the

machine is sitting idle in stick mode the

Green VRD on light will illuminate to indicate

the voltage is reduced below the set limit. If

the VRD device is not enabled (factory

default) from the set up menu or while weld-

ing the red VRD off light will illuminate to

show that output voltage is present above the

limit.

Note: The green VRD on light will illuminate in TIG

mode until the output is triggered even when VRD

is disabled. Also note that enabling VRD to reduce

the output voltage can make striking a stick elec-

trode more difficult.

b. General Alarm – Yellow LED which is lit when

faults exist with the power source or optional

cooler, such as over temperature, coolant

blockage, etc.

DYNAMIC LCD DISPLAY

The Dynamic display is divided into several sections

(Refer to Figure B.4):

Figure B.4

1. The Weld Sequence Diagram shows the various

parameters that can be selected and adjusted and

their preset values. As the push button/rotary

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

parameter. Depressing the button again 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)

2. The Parameter Display Section shows the select-

ed parameter its display icon and preset value. To

change the value, rotate the push button/rotary

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.

current selection made by the corresponding weld

push buttons (A-F). Refer to Table B.2 for a full list

of all parameters and their ranges. Below is a

description of the function of each push button and

display:

Two-Step with Foot Pedal -This

mode is only available when the

machine senses a remote amperage

control device is plugged in. It is used

when a foot or hand amptrol 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 weld-

ing 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 start 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 ups-

lope time. Depressing the arc start

switch again causes the output to

ramp down to the finish current level

over the downslope time. Finally

releasing the arc start switch causes

the arc to go out. (Refer to Figure B.6)

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 cur-

rent can be independently set and

upslope and downslope times are

adjustable. (Refer to Figure B.5)
