POWER FEED ® 10M SINGLE WIRE FEEDER
ARC CONTROL
PULSE
FREQUENCY:
(Low)-10.0 to
(High)+10.0 DESCRIPTION
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
0 to 10 seconds
RUN-IN WFS:
Off, 50 to150 in/min.
Start Procedure
DESCRIPTION
Adjusts the time the 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.

Spot Timer:
0 to 10 Seconds
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 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.
Adjusts the time welding will
continue even if tigger is still
pulled. This option has no
effect in 4-Step Trigger Mode.
