Preflow Time adjusts the time that
shielding gas flows after the trigger is pulled
and prior to feeding.
Adjust range: from 0 seconds (OFF) to 25 seconds
(factory default is set at Auto mode).
Postflow Time adjusts the time that
shielding gas flows after the welding output
turns off.
Adjust range: from 0 seconds (OFF) to 25 seconds
(factory default is set at Auto mode).
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.
Adjust range: from OFF to 0.25 seconds (factory
default is set at Auto mode).
Spot Timer– adjusts the time welding will
continue even if the trigger is still pulled.
This option has no effect in 4-Step Trigger
Mode.

from the time the trigger is pulled until an arc
is established.
Adjust range: from minimum to maximum WFS
(factory default is set at Auto mode).
The Start Procedure – controls the WFS
and Volts (or Trim) for 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.
Adjust time range: from 0 seconds (OFF) to
10 seconds.
Crater Procedure – controls the WFS (or
value in ampere units) and Volts (or 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
