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 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.

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.

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.

COAXIAL WELD CABLE

Coaxial welding cables are specially designed welding

cables for STT™ and pulse welding. Coaxial weld cables

feature low inductance, allowing fast changes in the weld

current. Regular cables have a higher inductance which

may distort the STT™ waveshape. Inductance becomes

more severe as the weld cables become longer.

Coaxial weld cables are recommended for STT™ weld-

ing, especially when the total weld cable length (elec-

trode cable + work cable) exceeds 50 feet (7.6m). See

Table A.2.

A coaxial weld cable is constructed with multiple small

leads wrapped around one large lead. The large inner

lead connects to the electrode stud on the power source

and the electrode connection on the wire feeder. The

small leads combine together to form the work lead, one

end attached to the power source and the other end to

the work piece.

To install:

1. Turn the input power off at the welding power source.

2. Connect one end of the center lead to the power

source electrode connection, and the other end to the

wire feeder electrode connection.

3. Connect the outer lead bundle to the power source

work connection, and the other end to the work piece.

Minimize the length of any work lead extension for

best results.

4. Insulate all connections.

SHIELDING GAS CONNECTION

CYLINDER may explode if

damaged.

• Keep cylinder upright and

chained to support.

• Keep cylinder away from areas where it may be

damaged.

• Never lift welder with cylinder attached.

• Never allow welding electrode to touch cylinder.

• Keep cylinder away from welding or other live

electrical circuits.

• BUILD UP OF SHIELDING GAS MAY

HARM HEALTH OR KILL.

• Shut off shielding gas supply when not

in use.

• See American National Standard Z-49.1, "Safety

in Welding and Cutting” Published by the

American Welding Society.

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

Maximum inlet pressure is 100 psi. (6.9 bar.)

Install the shielding gas supply as follows:

1. Secure the cylinder to prevent it from falling.

2. Remove the cylinder cap. Inspect the cylinder valves

and regulator for damaged threads, dirt, dust, oil or

grease. Remove dust and dirt with a clean cloth. DO

NOT ATTACH THE REGULATOR IF OIL, GREASE

OR DAMAGE IS PRESENT! Inform your gas supplier

of this condition. Oil or grease in the presence of high

pressure oxygen is explosive.

3. Stand to one side away from the outlet and open the

cylinder valve for an instant. This blows away any dust

or dirt which may have accumulated in the valve out-

let.

4. Attach the flow regulator to the cylinder valve and

tighten the union nut(s) securely with a wrench. Note:

if connecting to 100% CO

cylinder, insert regulator

adapter between regulator and cylinder valve. If

adapter is equipped with a plastic washer, be sure it is

seated for connection to the CO

cylinder.

WARNING

5. Attach one end of the inlet hose to the outlet fitting of

the flow regulator. Attach the other end to the welding

system shielding gas inlet. Tighten the union nuts with

a wrench.

6. Before opening the cylinder valve, turn the regulator

adjusting knob counterclockwise until the adjusting

spring pressure is released.

7. Standing to one side, open the cylinder valve slowly a

fraction of a turn. When the cylinder pressure gage

stops moving, open the valve fully.

8. The flow regulator is adjustable. Adjust it to the flow

rate recommended for the procedure and process

being used before making a weld.

applications.

The MAXTRAC 4 roll wire drive gives steady feeding

of all wire sizes and types. The drive features split

wire guides, tool-less drive roll changing, dual spring

pressure arms and changeable gun bushings all

mounted in a precision die cast aluminum frame. A

right angle gear box efficiently transfers motor power

for both high torque and high speed.

The AutoDrive 4R90 is optimized for the FANUC

AM100iC arm. The small, light weight package maxi-

mizes arm speed and working envelope. Quick

release mounting makes for fast servicing of the feed-

er and torch.

General Functional Description
