6-5. Manual MIG Setup Mode
1 Setup Button
2 Left Knob
3 Right Knob
4 Home Button
To enter the Setup menu from the Manual
Mode home screen, press Setup.
Once in the Setup menu, rotate the left knob
to find a particular item, and rotate the right
knob to change setting or status.
Press Home to save settings and return to
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 diameter
that matches the wire being used.
Inductance : Changes the fluidity of the weld
puddle. Increasing inductance produces a
more fluid, softer arc. Decreasing inductance
produces a stiffer arc. Inductance settings
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 depressed
and before the welding arc can start. Preflow
settings range from Disabled to 5 seconds.
Postflow : The amount of time that the shield-
ing gas will flow after the arc has been shut off.
Postflow settings range from Disabled 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 t : 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. See Section 6-6.
Spot Timer : The amount of time that the arc
can be active before it shuts off automatically.
Spot timer setting range is from Disabled 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 continuously
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 fea-
ture 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 weld-
ing power source. The range is 0 to 250, and
the default value is 130. The AlumaPro 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.
