ARC

 

FORCE

 

FUNCTION

 

Advantages:

 

‐ 

enhanced

 

short

arc

 

welding

 

stability;

 

‐ 

better

 

transfer

 

of

 

metal

 

drops

 

into

 

the

 

weld

 

pool;

 

‐ 

better

 

arc

 

striking;

 

‐ 

reduced

 

risk

 

of

 

electrode

 

sticking;

 

however,

 

it

 

is

 

not

 

the

 

Anti

Stick

 

function,

 

which

 

will

 

be

 

explained

 

in

 

the

 

next

 

paragraph;

 

‐ 

manual

 

adjustment;

 

allows

 

setting

 

the

 

function

 

level

 

to

 

minimum

 

value,

 

thus

 

reducing

 

power

 

consumption

 

(although

 

insignificantly),

 

as

 

well

 

as

 

heat

 

input

 

concentration

 

when

 

welding

 

thin

 

metal

 

pieces.

 

This

 

reduces

 

the

 

risk

 

of

 

burn

through,

 

but

 

also

 

reduces

 

stability

 

of

 

short

 

arc

 

burning

 

(the

 

machine

 

becomes

 

similar

 

to

 

a

 

transformer

 

source).

 

The

 

function

 

can

 

also

 

be

 

increased

 

to

 

maximum

 

value

 

for

 

even

 

better

 

stability

 

of

 

short

arc

 

burning,

 

but

 

this

 

requires

 

for

 

better

 

supply

 

mains

 

and

 

increases

 

the

 

risk

 

of

 

work

 

piece

 

burn

through.

 

The

 

result

 

is

 

achieved

 

by

 

the

 

following

 

means:

 

Due

 

to

 

reduction

 

of

 

arc

 

voltage

 

below

 

the

 

minimum

 

permissible

 

voltage

 

of

 

stable

 

arc

 

burning,

 

arc

 

current

 

increases

 

by

 

the

 

default

 

value

 

of

 

+40%.

 

In

 

the

 

additional

 

settings

 

you

 

can

 

change

 

both

 

Arc

 

Force

 

magnitude

 

[Ar.F]

 

and

 

trigger

 

level

 

of

 

this

 

function

 

[u.AF].

 

Do

 

not

 

set

 

Arc

 

Force

 

magnitude

 

and

 

trigger

 

level

 

to

 

unnecessarily

 

high

 

value,

 

because

 

at

 

high

 

limit

 

values,

 

especially

 

during

 

welding

 

with

 

thin

 

electrodes

 

less

 

than

 Ф

3.2

 

mm

 

in

 

diameter,

 

affects

 

actuation

 

of

 

Anti

Stick

 

function,

 

which

 

will

 

be

 

explained

 

in

 

the

 

next

 

paragraph.

 

See

 

paragraph

 

6.1

 

for

 

sequence

 

of

 

changing

 

the

 

value

 

of

 

any

 

function

 

in

 

the

 

current

 

welding

 

mode.
