10.0 (STIFF)

DESCRIPTION

Arc Focus adjusts the arc from
a wide, soft arc good for out of
position work to a narrow, stiff
arc preferred for faster travel
speeds. The pulse frequency is
lower with a soft arc and higher
with a stiff arc.

PREFLOW TIME

0 - 25.0 seconds

RUN-IN WFS:
Off, 30 to150 in/min.

Start Procedure

DESCRIPTION

Adjusts the time that shielding

gas flows after the trigger is
pulled and prior to feeding wire.

Run-in sets the wire feed
speed from the time the trigger
is pulled until an arc is estab-
lished.
The Start Procedure controls
the WFS, Trim at a specified
time at the beginning of the
weld. During the start time, the
machine will ramp up or down
from the Start Procedure to the
preset Welding Procedure.

EFFECT / RANGE

Postflow Time:
0 to 25.0 seconds

Burnback: 0 to .25
Seconds

Crater Procedure

FUNCTION

Adjusts the time that shielding
gas flows after the welding out-
put turns off.
The burnback time is the
amount of time that the weld
output continues after the wire
stops feeding. It prevents the
wire from sticking in the puddle
and prepares the end of the
wire for the next arc start.
Crater Procedure controls the
WFS and Trim for a specified
time at the end of the weld
after the trigger is released.
During the Crater time, the
machine will ramp up or down
from the Weld Procedure to
the Crater Procedure.
