From

Miller

to

You

Thank

you

and

congratulations

on

choosing

Miller.

Now~

you

can

get

the

job

done

and

get

it

done

right.

We

know

you

dont

have

time

to

do

it

any

other

way.

Thats

why

when

Niels

Miller

first

started

building

arc

welders

in

1929,

he

made

sure

his

products

offered

long-lasting

value

and

superior

quality.

Like

you,

his

customers

couldnt

afford

anything

less.

Miller

products

had

to

be

more

than

the

best

they

could

be.

They

had

to

be

the

best

you

could

buy.

Today,

the

people

that

build

and

sell

Miller

products

continue

the

tradition.

Theyre

just

as

committed

to

providing

equipment

and

service

that

meets

the

high

standards

of

quality

and

value

established

in

1929.

This

Owners

Manual

is

designed

to

help

you

get

the

most

out

of

your

Miller

products.

Please

take

time

to

read

Considerations

About

Welding

And

The

Effects

Of

Low

Frequency

Electric

And

Magnetic

Fields

Welding

current,

as

it

flows

through

welding

cables,

will

cause

electro

magnetic

fields.

There has

been

and

still

is

some

concern

about

such

fields.

However,

after

examining

more

than

500

studies

spanning

17

years

of

reseajch,

a

special

blue

ribbon

committee

of

the

National

Research

Council

concluded

that:

The

body

of

evidence,

in

the

committees

judgment,

has

not

demonstrated

that

exposure

to

power-

frequency

electric

and

magnetic

fields

is

a

human-health

hazard.

However,

Studies

are

still

going

forth

and

evidence

continues

to

be

examined.

Until

the

final

conclusions

of

the

research

are

reached,

you

may

wish

to

minimize

your

exposure

to

electromagnetic

fields

when

welding

or

cutting.

To

reduce

magnetic

fields

in

the

workplace,

use

the

following

procedures:

1-5

EMF

Information

1.

Keep

cables

close

together

by

twisting

or

taping

them.

2.

Arrange

cables

to

one

side

and

away

from

the

operator.

3.

Do

not

coil

or

drape

cables

around

your

body.

4.

Keep

welding

power

source

and

cables

as

far

away

from

opera

tor

as

practical.

5.

Connect

work

clamp

to

workpiece

as

close

to

the

weld

as

possible.

About

Pacemakers:

Pacemaker

wearers

consult

your

If

cleared

by

then

following

the

procedures

is

recommended.
