EMF

Information

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

cc~ncern

about

such

fields.

However,

after

examining

more

than

500

studies

spanning

17

years

of

research,

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.

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

doctor

first.

If

cleared

by

your

doctor,

then

following

the

above

procedures

is

recommended.
