welding mode.
Items that can be adjusted from this menu
are:
Wire and Gas Type: Optimize arc starts
and weld performance by selecting the wire
type and gas being used.
Wire Diameter: Optimize arc starts and
weld performance by selecting the wire di-
ameter that matches the wire being used.
Inductance: Changes the fluidity of the weld
puddle. Increasing inductance produces a

more fluid, softer arc. Decreasing induc-
tance produces a stiffer arc. Inductance set-
tings range from 0 to 99. The default setting
is 50.
Preflow: The amount of time that the shield-
ing gas will flow after the trigger is de-
pressed and before the welding arc can
start. Preflow settings range from Disabled
to 5 seconds.
Postflow: The amount of time that the
shielding gas will flow after the arc has been
shut off. Postflow settings range from Dis-
abled to 5 seconds.
Run-In: The speed of the wire prior to the
welding arc being struck. Auto is the default
setting. The other options are Disabled or
Manual. Manual settings range from 5 to
150% of the welding wire feed speed.
FasTack : Enabling FasTack reduces arc
™
start time by automatically increasing the
run-in speed when doing repetitive arc
starts. FasTack automatically uses a slower
wire feed speed when the wire is cool and a
faster wire feed speed when the wire is hot.
Default setting is Disabled.

Crater: The amount of time the welding arc
stays on after the welding gun trigger is re-
leased. This feature is used to fill the void or
crater at the end of the weld. Crater settings
range from 0.1 to 5 seconds.
Spot Timer: The amount of time that the arc
can be active before it shuts off automati-
cally. Spot timer setting range is from Dis-
abled to 120 seconds. Spot timer is reset
upon release of welding gun trigger.
Stitch Timer: Used in conjunction with the
spot timer and while the trigger is continu-
ously depressed. Controls the amount of
time that the arc will be inactive after the
spot timer times out. Stitch time setting
range is from 1 to 120 seconds.
Set Up Push Motor Torque (SUP): This
feature is only displayed when an AlumaPro
Lite gun is connected to the welding power
source. The SUP setting adjusts the over
torque limit of the push motor inside the
welding power source. The range is 0 to
250, and the default value is 130. The Alu-
maPro Lite SUP value can be found on the
back end of the gun. Set the SUP value on
the machine to match the value on the gun.
