1.02 Important Safety Precautions

WARNINGS

OPERATION AND MAINTENANCE OF

PLASMA ARC EQUIPMENT CAN BE DAN-

GEROUS AND HAZARDOUS TO YOUR

HEALTH.

Plasma arc cutting produces intense electric and

magnetic emissions that may interfere with the

proper function of cardiac pacemakers, hearing

aids, or other electronic health equipment. Per-

sons who work near plasma arc cutting applica-

tions should consult their medical health profes-

sional and the manufacturer of the health

equipment to determine whether a hazard exists.

To prevent possible injury, read, understand and

follow all warnings, safety precautions and in-

structions before using the equipment. Call 1-603-

298-5711 or your local distributor if you have any

questions.

GASES AND FUMES

Gases and fumes produced during the plasma cutting

process can be dangerous and hazardous to your health.

• Keep all fumes and gases from the breathing

area. Keep your head out of the welding fume

plume.

• Use an air-supplied respirator if ventilation is

not adequate to remove all fumes and gases.

• The kinds of fumes and gases from the plasma

arc depend on the kind of metal being used, coat-

ings on the metal, and the different processes. You

must be very careful when cutting or welding any

metals which may contain one or more of the fol-

lowing:

Antimony Chromium Mer-

cury

Arsenic Cobalt Nickel

Barium Copper Selenium

Beryllium Lead Silver

Cadmium Manganese Vanadium

• Always read the Material Safety Data Sheets

(MSDS) that should be supplied with the material

you are using. These MSDSs will give you the in-

formation regarding the kind and amount of fumes

and gases that may be dangerous to your health.

• For information on how to test for fumes and

gases in your workplace, refer to item 1 in Subsec-

tion 1.03, Publications in this manual.

• Use special equipment, such as water or down

draft cutting tables, to capture fumes and gases.

• Do not use the plasma torch in an area where

combustible or explosive gases or materials are lo-

cated.

• Phosgene, a toxic gas, is generated from the va-

pors of chlorinated solvents and cleansers. Remove

all sources of these vapors.

• This product, when used for welding or cutting,

produces fumes or gases which contain chemicals

known to the State of California to cause birth de-

fects and, in some cases, cancer. (California Health

& Safety Code Sec. 25249.5 et seq.)

ELECTRIC SHOCK

Electric Shock can injure or kill. The plasma arc process

uses and produces high voltage electrical energy. This

electric energy can cause severe or fatal shock to the op-

erator or others in the workplace.

GENERAL INFORMATION 2 Date: November 15, 2001

• Never touch any parts that are electrically “live”

or “hot.”

• Wear dry gloves and clothing. Insulate yourself

from the work piece or other parts of the welding

circuit.

• Repair or replace all worn or damaged parts.

• Extra care must be taken when the workplace is

moist or damp.

• Install and maintain equipment according to

NEC code, refer to item 9 in Subsection 1.03, Pub-

lications.

• Disconnect power source before performing any

service or repairs.

• Read and follow all the instructions in the Op-

erating Manual.

FIRE AND EXPLOSION

Fire and explosion can be caused by hot slag, sparks, or

the plasma arc.

• Be sure there is no combustible or flammable ma-

terial in the workplace. Any material that cannot

be removed must be protected.

• Ventilate all flammable or explosive vapors from

the workplace.

• Do not cut or weld on containers that may have

held combustibles.

• Provide a fire watch when working in an area

where fire hazards may exist.

• Hydrogen gas may be formed and trapped un-

der aluminum workpieces when they are cut un-

derwater or while using a water table. DO NOT

cut aluminum alloys underwater or on a water

table unless the hydrogen gas can be eliminated or

dissipated. Trapped hydrogen gas that is ignited

will cause an explosion.

NOISE

Noise can cause permanent hearing loss. Plasma arc pro-

cesses can cause noise levels to exceed safe limits. You

must protect your ears from loud noise to prevent per-

manent loss of hearing.

• To protect your hearing from loud noise, wear

protective ear plugs and/or ear muffs. Protect oth-

ers in the workplace.

• Noise levels should be measured to be sure the

decibels (sound) do not exceed safe levels.

• For information on how to test for noise, see item

1 in Subsection 1.03, Publications, in this manual.

PLASMA ARC RAYS

Plasma Arc Rays can injure your eyes and burn your skin.

The plasma arc process produces very bright ultra violet

and infra red light. These arc rays will damage your

eyes and burn your skin if you are not properly protected.

• To protect your eyes, always wear a welding hel-

met or shield. Also always wear safety glasses with

side shields, goggles or other protective eye wear.

• Wear welding gloves and suitable clothing to

protect your skin from the arc rays and sparks.

• Keep helmet and safety glasses in good condi-

tion. Replace lenses when cracked, chipped or

dirty.

• Protect others in the work area from the arc rays.

Use protective booths, screens or shields.

• Use the shade of lens as suggested in the fol-

lowing per ANSI/ASC Z49.1:

Minimum Protective Suggested

Arc Current Shade No. Shade No.

Less Than 300* 8 9

300 - 400* 9 12

400 - 800* 10 14

* These values apply where the actual arc is clearly

seen. Experience has shown that lighter filters

may be used when the arc is hidden by the work-

piece.

FUMÉE et GAZ

GENERAL INFORMATION 4 Date: November 15, 2001

La fumée et les gaz produits par le procédé de jet de

plasma peuvent présenter des risques et des dangers de

santé.

• Eloignez toute fumée et gaz de votre zone de respira-

tion. Gardez votre tête hors de la plume de fumée

provenant du chalumeau.

• Utilisez un appareil respiratoire à alimentation en air

si l’aération fournie ne permet pas d’éliminer la fumée

et les gaz.

• Les sortes de gaz et de fumée provenant de l’arc de

plasma dépendent du genre de métal utilisé, des

revêtements se trouvant sur le métal et des différents

procédés. Vous devez prendre soin lorsque vous

coupez ou soudez tout métal pouvant contenir un ou

plusieurs des éléments suivants:

antimoine cadmium

mercure

argent chrome nickel

arsenic cobalt plomb

baryum cuivre sélénium

béryllium manganèse vana-

dium

• Lisez toujours les fiches de données sur la sécurité

des matières (sigle américain “MSDS”); celles-ci

devraient être fournies avec le matériel que vous

utilisez. Les MSDS contiennent des renseignements

quant à la quantité et la nature de la fumée et des gaz

pouvant poser des dangers de santé.

• Pour des informations sur la manière de tester la

fumée et les gaz de votre lieu de travail, consultez

l’article 1 et les documents cités à la page 5.

• Utilisez un équipement spécial tel que des tables de

coupe à débit d’eau ou à courant descendant pour

capter la fumée et les gaz.

• N’utilisez pas le chalumeau au jet de plasma dans une

zone où se trouvent des matières ou des gaz combus-

tibles ou explosifs.

• Le phosgène, un gaz toxique, est généré par la fumée

provenant des solvants et des produits de nettoyage

chlorés. Eliminez toute source de telle fumée.

• Ce produit, dans le procéder de soudage et de coupe,

produit de la fumée ou des gaz pouvant contenir des

éléments reconnu dans L’état de la Californie, qui

peuvent causer des défauts de naissance et le cancer.

(La sécurité de santé en Californie et la code sécurité

Sec. 25249.5 et seq.)

CHOC ELECTRIQUE

Les chocs électriques peuvent blesser ou même tuer. Le

procédé au jet de plasma requiert et produit de l’énergie

électrique haute tension. Cette énergie électrique peut

produire des chocs graves, voire mortels, pour l’opérateur

et les autres personnes sur le lieu de travail.

• Ne touchez jamais une pièce “sous tension” ou “vive”;

portez des gants et des vêtements secs. Isolez-vous

de la pièce de travail ou des autres parties du circuit

de soudage.

• Réparez ou remplacez toute pièce usée ou

endommagée.

• Prenez des soins particuliers lorsque la zone de tra-

vail est humide ou moite.

• Montez et maintenez le matériel conformément au

Code électrique national des Etats-Unis. (Voir la page

5, article 9.)

• Débranchez l’alimentation électrique avant tout tra-

vail d’entretien ou de réparation.

• Lisez et respectez toutes les consignes du Manuel de

consignes.

INCENDIE ET EXPLOSION

Les incendies et les explosions peuvent résulter des scories

chaudes, des étincelles ou de l’arc de plasma. Le procédé

à l’arc de plasma produit du métal, des étincelles, des

scories chaudes pouvant mettre le feu aux matières com-

bustibles ou provoquer l’explosion de fumées

inflammables.

• Soyez certain qu’aucune matière combustible ou in-

flammable ne se trouve sur le lieu de travail. Protégez

toute telle matière qu’il est impossible de retirer de la

zone de travail.

• Procurez une bonne aération de toutes les fumées

inflammables ou explosives.

• Ne coupez pas et ne soudez pas les conteneurs ayant

pu renfermer des matières combustibles.

• Prévoyez une veille d’incendie lors de tout travail dans

une zone présentant des dangers d’incendie.

• Le gas hydrogène peut se former ou s’accumuler sous

les pièces de travail en aluminium lorsqu’elles sont

coupées sous l’eau ou sur une table d’eau. NE PAS

couper les alliages en aluminium sous l’eau ou sur

une table d’eau à moins que le gas hydrogène peut

s’échapper ou se dissiper. Le gas hydrogène accumulé

explosera si enflammé.

Date: November 15, 2001 5 GENERAL INFORMATION

RAYONS D’ARC DE PLASMA

Les rayons provenant de l’arc de plasma peuvent blesser

vos yeux et brûler votre peau. Le procédé à l’arc de

plasma produit une lumière infra-rouge et des rayons

ultra-violets très forts. Ces rayons d’arc nuiront à vos

yeux et brûleront votre peau si vous ne vous protégez

pas correctement.

• Pour protéger vos yeux, portez toujours un casque ou

un écran de soudeur. Portez toujours des lunettes de

sécurité munies de parois latérales ou des lunettes de

protection ou une autre sorte de protection oculaire.

• Portez des gants de soudeur et un vêtement protecteur

approprié pour protéger votre peau contre les

étincelles et les rayons de l’arc.

• Maintenez votre casque et vos lunettes de protection

en bon état. Remplacez toute lentille sale ou

comportant fissure ou rognure.

• Protégez les autres personnes se trouvant sur la zone

de travail contre les rayons de l’arc en fournissant des

cabines ou des écrans de protection.

• Utilisez la nuance de lentille qui est suggèrée dans le

recommendation qui suivent ANSI/ASC Z49.1:

Nuance Minimum Nuance Suggerée

Courant Arc Protective Numéro Numéro

Moins de 300* 8 9

300 - 400* 9 12

400 - 800* 10 14

* Ces valeurs s’appliquent ou l’arc actuel est observé

clairement. L’experience a démontrer que les filtres

moins foncés peuvent être utilisés quand l’arc est

caché par moiceau de travail.

BRUIT

Le bruit peut provoquer une perte permanente de l’ouïe.

Les procédés de soudage à l’arc de plasma peuvent

provoquer des niveaux sonores supérieurs aux limites

normalement acceptables. Vous dú4ez vous protéger les

oreilles contre les bruits forts afin d’éviter une perte

permanente de l’ouïe.

• Pour protéger votre ouïe contre les bruits forts, portez

des tampons protecteurs et/ou des protections

auriculaires. Protégez également les autres personnes

se trouvant sur le lieu de travail.

• Il faut mesurer les niveaux sonores afin d’assurer que

les décibels (le bruit) ne dépassent pas les niveaux

sûrs.

• Pour des renseignements sur la manière de tester le

bruit, consultez l’article 1, page 5.

2.07 Introduction to Plasma Arc

Welding

Plasma is a gas which has been heated to an extremely

high temperature and ionized so that the gas becomes elec-

trically conductive. The welding process uses this plasma

gas to transfer an electric arc to the work piece. The metal

to be welded is melted by the heat of this arc.

In a Thermal Arc Plasma Welding Torch, a cool gas such

as argon enters Zone A (Figure 2-2). In Zone B, a pilot arc

between the electrode and the front of the torch heats and

ionizes the gas. An arc transfers to the work piece through

the column of gas in Zone C.

Figure 2-2 Thermal Arc Plasma Welding

By forcing the plasma gas and electric arc through a small

orifice, Thermal Arc torches deliver a high concentration

of heat to a very small area. The stiff, constricted plasma

arc is shown in Zone C. Direct current straight polarity

(DCSP) is used for plasma welding, as shown in the illus-

tration.

The exclusive Dual-Flow design of Thermal Arc welding

torches uses a shield gas, shown by the small arrows. The

shield gas surrounds the plasma arc and channels it to

the workpiece, shielding the welding puddle.

Coolant from the coolant recirculator flows through the

liquid cooled power leads to the torch head and back.

The plasma arc is infinitely variable from soft to stiff. Most

applications can best be accomplished with a softer arc

(lower plasma gas flow). Full penetration or ‘keyhole’

welding requires a stiff arc (high plasma gas flow).

Individual welding torch instruction manuals contain

detailed information on these parameters.

2.08 Theory of Operation

A. Plasma and Shield Gases

Plasma and shield gases flow through the ULTIMA-

150 at rates set at the console flow meter controls. The

flow rate of each gas is indicated on the front panel

flow meters. Solenoid valves inside the unit turn the

gases on and off. The gas pressure interlock shuts the

system down if plasma gas pressure falls below 25

psi.

The plasma gas flows through the positive (black)

torch lead, around the electrode and gas distributor,

and out through the tip orifice. The shield gas flows

through the negative (yellow) torch lead, around the

torch front end and out through the shield cup.

Two pressure switches act as an interlock for the gas

supply. If supply pressure falls below minimum re-

quirements the pressure switches will open, shutting

off the power to the contactor, and the GAS indicator,

will go out. When adequate gas supply pressure is

available the pressure switches close, allowing power

to be resumed for welding.

B. Pilot Arc

When the torch is started a pilot arc is established

between the electrode and cutting tip. This pilot arc

creates a path for the main arc to transfer to the work.

Direct current (DC) alone is not enough to start the

main welding arc. High frequency is used momen-

tarily. The high frequency jumps between the tip and

electrode with the DC following, then the high fre-

quency turns off. The Pilot Indicator will be lighted

when the pilot arc is enabled.

C. Current Control

The welding current is controlled by remote or at the

power supply. The weld arc ON/OFF is controlled

remotely by the user - by remote pendant, foot control,

or remote signal.

D. Coolant Flow

Coolant flows from the coolant recirculator, through

the negative torch lead to the torch head and returns

through the positive torch lead. The coolant pressure

interlock shuts the system down if the coolant pres-

sure falls below 35 psi.

E. Welding Current

The power supply provides the welding current. The

negative (green) output is connected to the torch elec-

trode through the liquid cooled lead. The positive

output is connected to the workpiece through the work

cable.

SECTION 3:

INSTALLATION

3.01 Introduction

This section describes installation procedures for the

ULTIMA-150 Power Supply. These instructions apply

to the power supply only; installation procedures for

options and accessories can be found in manuals pro-

vided for those components.

3.02 Site Location

Select a clean, dry location with good ventilation and ad-

equate working space around all components. The power

supply is cooled by air flow through the front and rear.

Air flow must not be obstructed. At least 2 feet (0.61 m) of

clearance should be provided at the front and rear with at

least 6 inches (0.15 m) of clearance on each side.

CAUTION

Operation without proper air flow will inhibit

proper cooling and reduce duty cycle.

NOTE

Review the safety precautions in the front of this

manual to be sure that the location meets all safety

requirements.

3.03 Unpacking

The ULTIMA-150 is carefully packed to protect it from

damage during shipping. Components may be packed in

one carton or separately in several cartons, depending on

the system configuration and accessories ordered.

1. Unpack each item and remove all packing mate-

rial.

2. Locate the packing list(s) and use the list to iden-

tify and account for each item.

3. Inspect each item for possible shipping damage. If

damage is evident, contact your distributor before

proceeding with installation.

3.04 Primary Input Power

Connections

The ULTIMA-150 Plasma Welding Power Supply accepts

input voltages from 200V to 460V. Input can be 50 or 60

Hz, single-phase or three-phase.

The primary power source, power cable, and plug (sup-

plied by user) must conform to the local electric code and

the recommended circuit protection and wiring require-

ments. (See Appendix I for requirements.)

NOTE

Every system is factory-wired for 460V three-phase

input. For any other input voltage, the power sup-

ply must be reset by the user. Refer to Section 3.05,

Voltage Changeover, for instructions on how to

change the voltage setting.

For 575 Volt operation, an optional Transformer Module is

available. It is factory set to step down to 460V three-

phase input.

NOTE

Input power connections can be made directly to a

properly fused disconnect or by using a plug which

conforms to the recommended ratings.

WARNING

Disconnect primary power at the source before as-

sembling the power supply, torch parts or torch and

leads assemblies.
