EFFECT / RANGE
Preflow Time
Adjusts the time that shielding gas
0 - 10 seconds
flows after the trigger is pulled
and prior to feeding wire.
Run-In WFS: Run-In sets the wire feed
Off, 50 to150 in/min. speed from the time the trigger
is pulled until an arc is estab-
lished.
Start Procedure The Start Procedure controls
0 - 10 seconds the WFS and Volts for a speci-
fied time at the beginning of
the weld. During the start time,
the machine will ramp up or

EFFECT / RANGE
Postflow Time Adjusts the time that shielding
0 to 10 seconds gas flows after the welding out-
put turns off.
Crater Procedure Crater Procedure controls the
0 TO 10.0 SECONDS 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.
Burnback: The burnback time is the
0 to .25 Seconds 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.
