ARC CONTROL

 

 

 

 

 

 

 

 

 

ARC FORCE

 

 

DESCRIPTION

 

 

 

(Soft)-10.0 to

 

 

Arc Force adjusts the short cir-

 

 

 

(Crisp)+10.0

 

 

cuit current for a soft arc, or for

 

 

 

 

 

 

a forceful, driving arc. It helps to

 

 

 

 

 

 

prevent sticking and shorting

 

 

 

 

 

 

organic coated electrodes, par-

 

 

 

 

 

 

 

 

 

ticularity globular transfer types

 

 

 

 

 

 

such as stainless and low

 

 

 

 

 

 

hydrogen. Arc Force is espe-

 

 

 

 

 

 

cially effective for root pass on

 

 

 

 

 

 

pipe with stainless electrode

 

 

 

 

 

 

and helps to minimize spatter

 

 

 

 

 

 

for certain electrodes and pro-

 

 

 

 

 

 

cedure as with low hydrogen,

 

 

 

 

 

 

etc.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

START OPTIONS

 

 

 

 

 

START TIME:

 

 

FUNCTION

 

 

 

 

 

 

0 to 10 seconds

 

 

If no remote control is installed,

 

 

 

 

this control sets the time for the

 

 

 

 

weld output to ramp up or down

 

 

 

 

from a preset Start current to

 

 

 

 

the preset Weld current. Use

 

 

 

 

the WFS/AMP knob to adjust

 

 

 

 

Start current while the Start

 

 

 

 

Options LED is displayed.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

END OPTIONS

No arc ending options are active for SMAW (Stick) welding modes.
