FREQ.MODULATION
(Low)-10.0 to

(Low)-10.0 to
(High)+10.0
DESCRIPTION
For Pulse -On-Pulse modes,
Arc controls changes the frequ-
ency modulation. The freque-
-ncy modulation controls the
spacing of the ripples in the
weld. Use low values for slow
travel speeds and wide welds,
and high values for fast travel
speeds and narrower welds.
For Pulse modes, Arc Control
changes the pulsing frequency.
When the frequency changes,
the Power Wave system auto-
matically adjusts the back-
ground current to maintain a
similar heat input into the weld.
Low frequencies give more con-
trol over the puddle and high
frequencies minimize spatter.
Preflow Time
Run-In WFS:
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 or 2.5 seconds.
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.

Burnback:
Crater Procedure
FUNCTION
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.
