For Pulse modes, Arc Control
FREQUENCY:
changes the pulsing frequency.
(Low)-10.0 to
When the frequency changes,
(High)+10.0
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.
PULSE-ON-PULSE
For Pulse -On-Pulse modes,
FREQ.MODULATION Arc controls changes the frequ-
ency modulation. The freque-
(Low)-10.0 to
-ncy modulation controls the
(High)+10.0
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.

START OPTIONS
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.
END OPTIONS
FUNCTION
Adjust the time welding will
continue even if the trigger
is still pulled. This option
has no effect in 4-Step
Trigger Mode.
Crater Procedure controls the
WFS and Volts 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.
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.
Adjusts the time that shielding
gas flows after the welding out-
put turns off.
