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

iiii WELDING EQUIPMENT 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

iiiiii

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 EQUIPMENT SAFETY

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.

WELDING EQUIPMENT SAFETY

PRÉCAUTIONS DE SÛRETÉ

Pour votre propre protection lire et observer toutes les instruc-

tions et les précautions de sûreté specifiques qui parraissent

dans ce manuel aussi bien que les précautions de sûreté

générales suivantes:

Sûreté Pour Soudage A L’Arc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à l’électrode et à la piéce sont sous tension

quand la machine à souder est en marche. Eviter toujours

tout contact entre les parties sous tension et la peau nue

ou les vétements mouillés. Porter des gants secs et sans

trous pour isoler les mains.

b. Faire trés attention de bien s’isoler de la masse quand on

soude dans des endroits humides, ou sur un plancher

metallique ou des grilles metalliques, principalement dans

les positions assis ou couché pour lesquelles une

grande partie du corps peut être en contact avec la

masse.

c. Maintenir le porte-électrode, la pince de masse, le câble

de soudage et la machine à souder en bon et sûr état

defonctionnement.

d.Ne jamais plonger le porte-électrode dans l’eau pour le

refroidir.

e. Ne jamais toucher simultanément les parties sous tension

des porte-électrodes connectés à deux machines à soud-

er 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 pro-

téger contre les chutes dans le cas ou on recoit un choc. Ne

jamais enrouler le câble-électrode autour de n’importe quelle

partie du corps.

3. Un coup d’arc peut être plus sévère qu’un coup de soliel,

donc:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi qu’un verre blanc afin de se protéger les yeux du

rayonnement de l’arc et des projections quand on soude

ou quand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de

l‘arc.

c. Protéger l’autre personnel travaillant à proximité au

soudage à l’aide d’écrans appropriés et non-inflamma-

bles.

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,

pantalons sans revers, et chaussures montantes.

5. Toujours porter des lunettes de sécurité dans la zone de

soudage. Utiliser des lunettes avec écrans lateraux dans les

zones où l’on pique le laitier.

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 forte-

ment 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 dis-

positif de montage ou la piece à souder doit être branché à

une bonne mise à la terre.

2. Autant que possible, I’installation et l’entretien du poste

seront effectués par un électricien qualifié.

3. Avant de faires des travaux à l’interieur de poste, la

debrancher à l’interrupteur à la boite de fusibles.

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

place.

LOAD BANK SAFETY

The load bank is an industrial test unit designed to be

used indoors or outdoors (sheltered from moisture).

However, because the nature of the load bank’s func-

tion is the dissipation of electrical energy, electrical

energy is transformed into heat by the resistor ele-

ments. The heat is removed from the load bank by

airflow through the resistor elements. If there are any

restrictions or stoppage of airflow, the load bank may

overheat. For safe operation the following recommen-

dations should be observed:

1. Read the manual before operating the Load Bank.

2. Run an approved ground wire from the Load Bank

ground lug located on the connection panel to the

frame of the power source. Run an approved

ground wire from the power source frame to a

good earth ground. Size ground wire in accor-

dance with National Electrical Code and any local

codes.

3. Do not bypass the airflow safety switch or temper-

ature sensing switch to prevent nuisance tripping.

The switches will drop out the load if insufficient

cooling air is reaching the elements.

4. Replace any burned out lamps on the control

panel. Each lamp is an indication that a system

is active or has failed and is important to the oper-

ation of the unit and safety of the operator.

ELECTRIC SHOCK can kill.

Personal injury from electrical shock

may result if all sources of power are

not disconnected before servicing.

Only qualified personnel should

Install, Operate and Service this equip-

ment.

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

5. Maintenance should be performed with no power

on the unit. The majority of troubleshooting can

be performed with an ohmmeter. There are mul-

tiple sources of input power to the Load Bank.

Insure each is disconnected.

6. Venting the heated air from the exhaust toward

overhead cables, sprinkler systems, or into a

room with insufficient volume or "Make-Up" air, is

a potential hazard. The Load Bank should be

used in a cool, well-ventilated area.

7. Allow cool room air to pass into the unit to cool

the elements. Do not allow the unit to be placed

where hot exhaust air can recirculate back

through the unit causing a constant rise in cooling

air temperature.

8. After running a load test, residual heat may be

removed from the load bank by allowing the blow-

er to operate for a few minutes after load is

removed. This procedure is not required for load

bank integrity, but it may guard operating person-

nel from possible burn injuries.

9. The operator should avoid coming in contact with

the resistor elements or surrounding covers during

and for some time after operation. These por-

tions of the load bank become hot .

10. Do not allow objects to enter or block the air

intake or exhaust of the load bank. A blockage

would cause overheating. If an object enters the

screens, it may cause damage to the resistor ele-

ments, possibly shorting them and causing shock

and fire hazards.

11. Emergency Shutdown Procedure

A. In an emergency, shut down the MASTER

LOAD switch, then the power source. The

MASTER LOAD switch will allow disconnec-

tion of all load steps and still allow for the fan

motor to run, cooling any heated elements.

B. The POWER ON/OFF switch will disconnect

both load steps and fan motor. The power

source EMERGENCY OFF switch should be

located near the load system.

12. An approved electrical fire extinguisher should be

on hand at all times.

13. It is the responsibility of the customer to take dili-

gent care in installing the Load Bank. The

National Electrical Code (NEC), sound local elec-

trical and safety codes, and the Occupational

Safety and Health Act (OSHA) should be followed

when installing the equipment to reduce hazards

to persons and property.

14. Flammable objects (cardboard, paper, etc.) must

not be stored near the load bank

15. As part of your safety program, an initial inspec-

tion after receiving the unit(s) and periodic preven-

tive maintenance and safety inspections should

be conducted to insure the reliability and safety.

ENCLOSURE

The outside dimensions of the Master Load 750 Load

Bank are listed on Technical Specifications page at

the beginning of this section of the manual. The Load

Bank is mounted on casters. One set of casters has

lockable wheels.

Do not allow the Load Bank to be placed where hot

exhaust air can recirculate back through the unit caus-

ing a constant rise in cooling air temperature.

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

The Master Load 750 Load Bank contains a blower

(approximately 82dBA at 3 ft.) which provides the nec-

essary cooling air for the load elements. An exhaust

temperature sensor is provided to monitor the exhaust

temperature. This switch is electrically interlocked

with the load application circuit. If an unsafe tempera-

ture is detected in the exhaust of the Load Bank, the

BLOWER FAIL light comes on and the load is discon-

nected from the resistive elements.

Air to cool the load elements enters the screened

intakes located on one end of the Load Bank. The air

passes over the resistive elements and is then dis-

charged through the screened opening at the other

end of the Load Bank.

The Load Bank also contains fuses for short circuit

protection. The control circuit is protected with a 15

amp fuse while the voltmeters are protected with 3

amp fuses.

Do not operate the Load Bank with any screen or

cover removed. This may expose the operator to

high voltage and rotating fan blades.

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

Do not exceed the voltage rating of load resistive cir-

cuit configuration.
