Profile Pulse; Factory Reset Procedure - Miller 300739 Owner's Manual

8-7. Profile Pulse

Profile Pulse optimizes Aluminum weld
bead appearance by producing welds with
consistently spaced ripple patterns, similar
to GTAW. This feature has been designed
to operate in a Synergic Pulsed MIG sys-
tem. The consistent ripple pattern is
achieved by periodically changing both the
wire feed speed and power level. The aver-
age wire feed speed is determined by the
value the unit is set to for welding.
.
By default, Profile Pulse parameters
are hidden from the Setup Menu. To
view the parameters, the (PROF) set-
ting in the Setup Menu Level 2 must be

.
Start with the wire feeder on.
1 Press and hold the Setup button until SET UP appears in display.
2 Rotate left Adjust knob until INFO NONE appears.
3 Press Setup button and hold again until FACTORY appears. The first menu is FACT DFLT. For AlumaFeed - turn left knob until FACT DFLT
displays.
4 Turn the Adjust knob to the right one click, and a 5 second timer will start counting down in the right display.
5 After timer reaches zero, FACT DONE will appear.
6 Press and release Setup button one last time, and the front display will illuminate as if it were turned on. SET UP will be exited back to the
normal voltage and wire feed speed display.
Reset is now complete.
set to (YES). See section 8-2.
Profile Pulse Items that can be adjusted in
the Setup Menu are:
Profile Pulse ON/OFF (PROF) − Allows
Profile Pulse to be turned on or off.
Profile Pulse Frequency (P.FRQ) − Sets
the spacing between ripples in the weld
bead. Range of this setting is from (0.1 to
5.0) pulses per second. See Figures 1 and
2 below.
Profile Pulse Wire Feed Speed Change
(P.WFS) − Sets the percentage of change
above and below the wire feed speed the

unit is set to for welding. Range of this set-
ting is (X0.00 to X0.30). Example: If the wire
feed speed is 200 and (P.WFS) is set to
(X0.10), the wire feed speed will alternate
between 180 and 220 ipm.
Profile Pulse Arc Length (P.AL) − Sets an
arc length correction factor for the lower
wire feed speed. This setting is a percent-
age of the arc length the unit is set to for
welding. Range of this setting is from (X0.5
to X1.5). Example: If the arc length for weld-
ing is set to 50 and (P.AL) is set to (X1.1),
the arc length setting for the lower wire feed
speed is 55.
