exact

change

of

heat

input

into

the

weld

pool,

for

example,

when

he/she

compares

this

current

with

another

base

voltage

without

the

pulsed

welding

mode.

If

the

goal

is

to

reduce

heat

input

into

the

weld

using

the

pulsed

mode

(for

example,

when

welding

thin

metal

pieces),

it

is

enough

to

reduce

base

voltage

of

the

source

in

a

standard

way,

whereas

preset

amplitudes

of

pulses

and

pauses

will

adapt

to

this

voltage

automatically.

Thus,

the

user

will

clearly

see

the

reduction

of

heat

input

into

the

weld

compared

to

the

previous

mode,

while

varying

power

and

duty

ratio

of

pulses

in

any

combination

in

order

to

achieve

the

required

process.

This

task

is

not

easy,

since

several

parameters

need

to

be

adjusted

at

the

same

time.

These

parameters

are

set

differently

in

different

situations

in

accordance

with

welding

operator's

requirements.

See

paragraph

6.1

for

sequence

of

changing

the

value

of

any

function

in

the

current

welding

mode.

6. MACHINE

SETTING

If

buttons

on

the

front

panel

are

not

touched,

the

machine

always

displays

value

of

the

main

parameter

of

the

current

welding

mode

on

its

digital

indicator:

1) in

MMA

mode

–

arc

current;

2) in

TIG

mode

–

arc

current;

3) in

MIG/MAG

–

arc

voltage.

Buttons

3

on

the

front

panel

serve

to

change

the

value

of

the

selected

function

or

the

main

parameter.

Button

5

on

the

machine

front

panel

is

multifunctional

and

allows

for

the

following:

1)

end

‐

around

selection

of

any

function

in

the

current

welding

mode

(quick

pressing);

2)

reset

of

all

functions

to

factory

settings

for

the

current

welding

mode

(holding

for

more

than

12

s).

Button

7

on

the

front

panel

serve

to

change

the

welding

mode

end

‐

around.

SWITCHING

TO

THE

REQUIRED

FUNCTION

When

button

5

is

pressed,

the

digital

display

shows

graphic

name

of

the

current

function,

which

can

be

viewed

while

the

button

is

pressed.

After

the

button

is

released,

the

display

shows

current

value

of

this

function,

which

can

be

increased

or

decreased

with

buttons

3

.

By

quickly

pressing

and

releasing

button

5

,

one

can

switch

to

the

next

function

end

‐

around.

ATTENTION:

If

button

5

is

being

held

for

a

long

time

while

the

user

views

the

function

name,

then

in

about

10

s

the

digital

board

will

display

countdown

333…222…111

warning

about

reset

of

all

settings

of

the

current

mode.

This

option

will

be

considered

in

the

paragraph

below.
