WARNING

Mar ‘95

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 below Threshold Limit Values (TLV)

using local exhaust or mechanical ventilation. In

confined spaces or in some circumstances, outdoors, a

respirator may be required. Additional precautions are

also required when welding on galvanized steel.

5.b.

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

products.

5.c. 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.d. 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.e. Also see item 1.b.

Mar ‘95

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.

SAFETY

iii

Mar ‘95

WELDING SPARKS can

cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

the welding sparks from starting a fire.

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.

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 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.

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 ray-

onnement de l’arc et des projections quand on soude ou

quand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de

l‘arc.

c. Protéger l’autre personnel travaillant à proximité au

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

4. Des gouttes de laitier en fusion sont émises de l’arc de

soudage. Se protéger avec des vêtements de protection libres

de l’huile, tels que les gants en cuir, chemise épaisse, 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 l’on pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin de

prévenir tout risque d’incendie dû aux étincelles.

7. Quand on ne soude pas, poser la pince à une endroit isolé de

la masse. Un court-circuit accidental peut provoquer un

échauffement et un risque d’incendie.

8. S’assurer que la masse est connectée le plus prés possible

de la zone de travail qu’il est pratique de le faire. Si on place

la masse sur la charpente de la construction ou d’autres

endroits éloignés de la zone de travail, on augmente le risque

de voir passer le courant de soudage par les chaines de lev-

age, câbles de grue, ou autres circuits. Cela peut provoquer

des risques d’incendie ou d’echauffement des chaines et des

câbles jusqu’à ce qu’ils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage.

Ceci est particuliérement important pour le soudage de tôles

galvanisées plombées, ou cadmiées ou tout autre métal qui

produit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenant

d’opérations de dégraissage, nettoyage ou pistolage. La

chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs

du solvant pour produire du phosgéne (gas fortement toxique)

ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté,

voir le code “Code for safety in welding and cutting” CSA

Standard W 117.2-1974.

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 debranch-

er à l’interrupteur à la boite de fusibles.

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

place.

LIFTING

Lift the machine by the lift bail only. The lift bail is

designed to lift the power source only. Do not attempt

to lift the V450-PRO (CE) with accessories attached to

it.

STACKING

V450-PRO (CE) machines can be stacked to a maxi-

mum of 3 high.

The bottom machine must always be placed on a

firm, secure, level surface. There is a danger of

machines toppling over if this precaution is not

taken.

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

MACHINE GROUNDING

The frame of the welder must be grounded. A ground

terminal marked with the symbol is located inside

the reconnect/input access door for this purpose. See

your local and national electrical codes for proper

grounding methods.

HIGH FREQUENCY PROTECTION

Locate the V450-PRO (CE) away from radio con-

trolled machinery.

The normal operation of the V450-PRO (CE) may

adversely affect the operation of RF controlled

equipment, which may result in bodily injury or

damage to the equipment.

INPUT CONNECTION

Only a qualified electrician should connect the

input leads to the V450-PRO (CE). Connections

should be made in accordance with all local and

national electrical codes and the connection dia-

gram located on the inside of the reconnect/input

access door of the machine. Failure to do so may

result in bodily injury or death.

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

Use a three-phase supply line. A 1.75 inch (45 mm)

diameter access hole for the input supply is located on

the upper left case back next to the input access door.

Connect L1, L2, L3 and ground according to the Input

Supply Connection Diagram decal located on the

inside of the input access door or refer to Figure A.1

on the following page.

SAFETY PRECAUTIONS

Read this entire installation section before you start

installation.

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 con-

nected to the welding system at the disconnect

switch or fuse box before working on the equipment.

• Do not touch electrically hot parts.

• Always connect the V450-PRO (CE) grounding lug

(located inside the reconnect input access door) to

a proper safety (Earth) ground.

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

SELECT SUITABLE LOCATION

Do not use the Invertec in outdoor environments without

appropriate protection. The V450-PRO (CE) power

source should not be subjected to falling water, nor

should any parts of it be submerged in water. Doing so

may cause improper operation as well as pose a safety

hazard. The best practice is to keep the machine in a dry,

sheltered area.

Do not mount the V450-PRO (CE) over combustible

surfaces. Where there is a combustible surface

directly under stationary or fixed electrical equip-

ment, that surface shall be covered with a steel plate

at least .060" (1.6mm) thick, which shall extend not

less than 5.90" (150mm) beyond the equipment on all

sides.

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

Place the welder where clean cooling air can freely circu-

late in through the rear louvers and out through the case

sides and bottom. Water, Dirt, dust, or any foreign materi-

al that can be drawn into the welder should be kept at a

minimum. Failure to observe these precautions can result

in excessive operating temperatures and nuisance shut-

downs.

Machines are equipped with F.A.N. (fan as needed) cir-

cuitry. The fan runs whenever the output is enabled,

whether under loaded or open circuit conditions. The fan

also runs for a period of time (approximately 5 minutes)

after the output is disabled, to ensure all components are

properly cooled.

If desired, the F.A.N. feature can be disabled (causing the

fan to run whenever the power source is on). To disable

F.A.N., connect leads 444 and X3A together at the output

of the solid state fan control relay, located on the back of

the Control PC board enclosure. (See Wiring Diagram)

wire sizes. Fuse the input circuit with the recommend-

ed super lag fuse or delay type breakers (also called

“inverse time” or “thermal/magnetic” circuit breakers).

Choose an input and grounding wire size according to

local or national electrical codes. Using fuses or circuit

breakers smaller than recommended may result in

“nuisance” shut-offs from welder inrush currents, even

if the machine is not being used at high currents.

INPUT VOLTAGE CONNECTION

PROCEDURE

Only a qualified electrician should connect the

input leads to the V450-PRO (CE). Connections

should be made in accordance with all local and

national electrical codes and the connection dia-

gram located on the inside of the reconnect/input

access door of the machine. Failure to do so may

result in bodily injury or death.

and to achieve the best possible operation, route all

cables directly to the work and wire feeder. Avoid

excessive lengths and do not coil excess cable.

Minimum work and electrode cable sizes are as follows:

TABLE A.1

(Current (60% Duty Cycle)

MINIMUM COPPER

WORK CABLE SIZE AWG

Up To-100 Ft. Length (30 m)

400 Amps 2/0 (67 mm

)

500 Amps 3/0 (85 mm

)

600 Amps 3/0 (85 mm

)

NOTE: K1796 coaxial welding cable is recommended

to reduce the cable inductance in long cable lengths.

This is especially important when Pulse welding up to

350 amps.

When using inverter type power sources like the

V450-PRO (CE), use the largest welding (electrode

and work) cables that are practical. At least 2/0 (67

) copper wire - even if the average output cur-

rent would not normally require it. When pulsing,

the pulse current can reach very high levels.

Voltage drops can become excessive, leading to

poor welding characteristics, if undersized weld-

ing cables are used.

CABLE INDUCTANCE, AND ITS EFFECTS

ON PULSE WELDING

For Pulse Welding processes, cable inductance will

cause the welding performance to degrade. For the

total welding loop length less than

50 ft.(15.24m), tradi-

tional welding cables may be used without any effects

on welding performance. For the total welding loop

length greater than

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

Welding Cables are recommended. The welding loop

length is defined as the total of electrode cable length

(A) + work cable length (B) + work length (C) (See

Figure A.2).

For long work piece lengths, a sliding ground should

be considered to keep the total welding loop length

less than

50 ft.(15.24m). (See Figure A.3.)

Output connections on some V450-PRO (CE) are

made via 1/2-13 threaded output studs located

beneath the spring loaded output cover at the bottom

of the case front.

Most welding applications run with the electrode being

positive (+). For those applications, connect the elec-

trode cable between the wire feeder and the positive

(+) output stud on the power source (located beneath

the spring loaded output cover near the bottom of the

case front). Connect the other end of the electrode

cable to the wire drive feed plate. The electrode cable

lug must be against the feed plate. Be sure the con-

nection to the feed plate makes tight metal-to-metal

electrical contact. The electrode cable should be sized

according to the specifications given in the work cable

connections section. Connect a work lead from the

negative (-) power source output stud to the work

piece. The work piece connection must be firm and

secure, especially if pulse welding is planned.

For additional Safety information regarding the elec-

trode and work cable set-up, See the standard "SAFE-

TY INFORMATION" located in the front of the

Instruction Manuals.

Excessive voltage drops caused by poor work

piece connections often result in unsatisfactory

welding performance.

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

NEGATIVE ELECTRODE POLARITY

When negative electrode polarity is required, such as

in some Innershield applications, switch the output

connections at the power source (electrode cable to

the negative (-) stud, and work cable to the positive (+)

stud).

General Instructions for Connection of Wire

Feeders to V450-Pro

Wire feeders other than those listed above may be

used provided that the auxiliary power supply rating of

the V450-Pro is not exceeded and the V450Pro output

is not actively controlled by the wire feeder. (Like an

LN-9). K867 universal adapter plug is required. See

connection diagram S24985 on page F-4.

REMOTE CONTROL OF INVERTEC

Remote Control K857, Hand Amptrol K963 and Foot

Amptrol K870 may be used.

PARALLEL OPERATION

The V450-Pro are operable in parallel in CC mode.

For best results, the currents of each machine should

be reasonably equally balanced. As an example, with

two machines set up in parallel for a 800 amps proce-

dure, each machine should be set to deliver approxi-

mately 400 amps, not 450 amps from one and 350

amps from the other. This will minimize nuisance shut-

down conditions. In general, more than two machines

in parallel will not be effective due to the voltage

requirements of procedures in that power range.

To set machine outputs, start with output control pots

and arc control pots in identical positions. Use the out-

put control pots to balance the currents and maintain

the desired current. The arc control pots should be

kept identical on the two machines.

WARNING

GENERAL DESCRIPTION

The Invertec V450-PRO (CE) offers multi-process CV,

CC, and DC welding and is rated 570 amps, 43 volts

at a 60% duty cycle.

DUTY CYCLE

The V450-PRO (CE) is rated at 570 amps, 60% duty

cycle (based on a 10 minute cycle). It is also rated at

450 amps, 100% duty cycle.

OPERATIONAL FEATURES and CONTROLS:

UPPER CONTROL PANEL

1. ON, OFF- SWITCH

2. AMPS Meter

• Prior to STICK or TIG operation (current flow), the

meter displays preset current value (either +/- 2

amps or +/- 3% (e.g. 3 amps on 100), whichever is

greater).

• Prior to CV operation, the meter displays four dash-

es indicating non-presettable AMPS.

• During welding, this meter displays actual average

amps.

• After welding, the meter holds the actual current

value for 5 seconds. Output adjustment while in the

"hold" period results in the "prior to operation" char-

acteristics stated above. The displays blink indicat-

ing that the machine is in the "Hold" period.

3. VOLT METER

• Prior to CV operation (current flow), the meter dis-

plays desired preset voltage value (+/- .5V).

• Prior to STICK or TIG operation, the meter displays

the Open Circuit Voltage of the Power Source or

four dashes if the output has not been turned on.

• During welding, this meter displays actual average

volts.

• After welding, the meter holds the actual voltage

value for 5 seconds. The displays blink indicating

that the machine is in the "Hold" period.

• Output adjustment while in the "hold" period results

in the "prior to operation" characteristics stated

above.

4. OUTPUT CONTROL

• Output control is conducted via a single turn poten-

tiometer.

• Adjustment is indicated by the meters as stated

above.

• When in TIG modes, this control sets the maximum

welding current. Full depression of a foot or hand

Amptrol results in the preset level of current.

5. WELD TERMINALS-REMOTE / ON

• Two status lights indicate the location of trigger con-

trol as determined by the "WELD TERMINALS"

push button.

• If trigger control is local "weld terminals on", the ON

display will be lit.

• If trigger control is remote "weld terminals remotely

controlled", the REMOTE display will be lit.

• The unit will power up in "pre-determined preferred"

trigger modes.

STICK = ON

CV = REMOTE

TIG = REMOTE if remote output controls are

attached to the machine.

TIG = 0N if remote output controls are not attached to

the machine.

For all versions, these trigger modes can be over-ridden

(switched) with the WELD TERMINALS push button. When

changed, the unit will power up in the configuration it was in

when it was last powered down.

B-2

OPERATION

B-2

THERMAL

• This status light indicates when the power source has

been driven into thermal overload. If the output terminals

were "ON", the "ON" light will blink indicating that the out-

put will be turned back on once the unit cools down to an

acceptable temperature level. If the unit was operating in

the "REMOTE" mode, the trigger will need to be opened

before or after the thermal has cleared and closed after

the machine has cooled down to an acceptable tempera-

ture to establish output.

CONTROL-REMOTE / LOCAL

• Two status lights indicate the location of output control as

pre-determined by the power sources auto-configure sys-

tem.

• The LOCAL display will be lit when control is at the power

source.

• The REMOTE display will be lit when a remote pot/control

is detected.

These Output Control configurations can be overridden

(switched) with the CONTROL push button. When

changed, the unit will power up in the configuration it was in

when it was last powered down.

Hidden Middle Control Panel – Process Set Up

Panel

The middle control panel is removable to allow for

upgrades (see Field Installed Options/Accessories).

Additionally, this panel is hidden by an access door to

provide protection to the controls.

8. WELD MODE SELECT - STANDARD (See

Figure B.1)

The Mode Control button selects from the following

welding modes.

CC-STICK SOFT: The Stick Soft process features con-

tinuous control ranging from 5 to 570 amps. This mode

was intended for most SMAW applications, and Arc

Gouging.

• Arc Gouging: Setting the output of the Stick Soft

mode to 570 amps or setting the arc control to maxi-

mum will enable the arc-gouging mode. The actual

output current will depend on the size of carbon used.

The recommended maximum size carbon is

3/8"(9.5mm).

• The Hot Start control regulates the starting current at

arc initiation. Hot Start can be adjusted from minimum

(0), with no additional current added at arc start, to

maximum (10), with double the preset current or 570

amps (max of machine) added for the first second

after arc initiation.

• The Arc Control regulates the Arc Force to adjust the

short circuit current. The minimum setting (-10) will

produce a "soft" arc and will produce minimal spatter.

The maximum setting (+10) will produce a "crisp" arc

and will minimize electrode sticking.

CC-STICK CRISP:The Stick Crisp mode features contin-

uous control from 5 to 570 amps with a crisp shorting

response optimized for E6010 type electrodes.

• Arc Gouging: Setting the output of the Stick Crisp

mode to 570 amps or setting the arc control to maxi-

mum will enable the arc-gouging mode. The actual

output current will depend on the size of carbon used.

The recommended maximum size carbon is

3/8"(9.5mm).

• The Hot Start control regulates the starting current at

arc initiation. Hot Start can adjust starting current up or

down by 25% of the preset value. The recommended

setting for Hot Start is 5 where the initial current is

equal to the preset current.

• The Arc Control regulates the Arc Force to adjust

the short circuit current. The minimum setting (-10)

will produce a "soft" arc and will produce minimal

spatter. The maximum setting (+10) will produce a

"crisp" arc and will minimize electrode sticking.

TIG GTAW: The TIG mode features continuous con-

trol from 5 to 570 amps. The TIG mode can be run in

either the TIG touch start or high frequency (optional

equipment required) assisted start mode.

• The Hot Start control selects the starting mode

desired. A setting of less than 5, the TIG lift start

mode is selected. The OCV is controlled below 10v

and the short circuit "TIG touch" current is main-

tained at 25 amps independent of the preset cur-

rent.

When the tungsten is lifted, an arc is initiated and

the output is regulated at the preset value. Hot start

settings between 0 and 5 regulate the arc initiation

current. A setting of 5 results in the most positive

arc initiation. A setting of 0 reduces hot start.

• Hot Start settings between 5 and 10, select high

frequency assisted starting TIG mode. In this

range, the OCV of the machine is controlled

between 50 and 70 volts. If using the Lincoln K930-

1 TIG Module, set the Hot start to 10 for maximum

OCV.

• The Arc Control is not used in the TIG mode.

CV-WIRE: The CV-WIRE mode features continuous

control from 10 to 40 volts. This mode was intended

for most GMAW, FCAW, and MCAW applications.

• The Hot Start control is not used in the CV-WIRE

mode.

• The Arc Control regulates pinch effect. At the mini-

mum setting (-10), minimizes pinch and results in a

soft arc. Low pinch settings are preferable for weld-

ing with gas mixes containing mostly inert gases. At

the maximum setting (+10), maximizes pinch effect

and results in a crisp arc. High pinch settings are

preferable for welding FCAW and GMAW with CO

CV-INNERSHIELD: The CV-INNERSHIELD mode

features continuous control from 10 to 45 volts. This

mode was designed for self-shielded flux cored wires

that require tight voltage control.

• The Hot Start control is not used in the CV-INNER-

SHIELD mode.

IINVERTEC V450-PRO (CE)

• The Arc Control regulates pinch effect. At the mini-

mum setting (-10), minimizes pinch and results in a

soft arc. At the maximum setting (+10), maximizes

pinch effect and results in a crisp arc. Most self-

shielded wires work well at an Arc Control setting of 5.
