Do

capacity.

The

weld

current

capacity

is

a

current

and

a

percentage

of

time

that

welding

can

be

performed

on

the

unit

within

a

ten

minute

period

without

causing

overheating

or

The

rated

weld

current

capacity

for

these

units

is

500

amperes

and

60%

allowing

welding

6

minutes

out

of

every

10

minutes

at

rated

If

the

welding

amperes

decrease,

the

percentage

of

time

for

welding

increases.

The

percentage

of

is

calculated

as

follows:

Actual

Reference

weld

(10 mAn)

If

welding

is

lowered

to

less

the

percentage

is

calculated

as

follows:

Percentage

of

=

x

Percentage

of

(Operating

For

example,

if

the

welding

is

350

amperes,

the

percentage

of

weld

time

is

determined

as

follows:

Percentage

of

weld

time

=

(

x

0.6

=

1.2

(120%)

(350)2

Because

the

percentage

is

over

100%,

welding

can

be

performed

continuously.

If

more

than

one

welding

power

supply

is

used

with

the

positioner,

the

operating

currents

are

added

together

as

follows:

Percentage

of

=

(

current)2

x

Percentage

of

(Operating

For

example,

if

2

power

sources

are

each

supplying

the

percentage

of

is

The

location

and

installation

method

are

very

important

for

providing

reliable

operation

of

the

positioner.

Environmental

conditions

can

have

a

direct

affect

on

the

service

life

of

the

positioner

and

associated

equipment.

Operating

precision

of

the

positioner,

such

as

positioning

and

interpolation

functions,

depend

significantly

on

the

condition

of

the

supporting

foundation.

The

foundation

should

have

enough

strength

to

not

only

withstand

the

static

load,

but

forces

from

acceleration

and

deceleration

during

positioner

operation.

check

the

4.

Provide

5.

The
