SECTION 3
displayed in the IPM and VOLTS windows respec-
tively and are set as follows:
(1) Power source. Four power sources are avail-
able for use with this feeder. The choices are,
the SVI-300i cv/cc and this designated by the
numeral "300"; and the VI-450, or the SVI-
450I, and these are designated by the nu-
meral "450"; and/or the V-650 cv/cc and this is
designated by the numeral "650". The Power
Source "numeral" designation selection is dis-
played in the left (IPM) window, and set using
the IPM Inc./Dec. toggle switch.
(2) Slope. In order to provide optimum starts with
the many Power Source and Slope combina-
tions, the same slope setting used on the
power source must also be preset on the wire
feeder control, and are designated as follows:
by the numeral "1" for Flat; by numeral "3" for
Medium; or by numeral "6" for Steep slope.
The slope "numeral" designation selected is
displayed in the right (VOLTS) window, and
set using the VOLTS Inc./Dec. toggle switch.
Remember, that the feeder slope selection
must always match the slope output se-
lected at the power source.
In order to help you select the correct Slope setting
for the Power Source used, refer to the chart follow-
ing:
Power
Source #1
SVI-300i X
SVI-450i X
VI-450 X
V-650 cv/cc X
Note, Slope codes indicate the following:
#1 = Flat = 1 volt/100 amps.
#3 = Medium = 3 volt/100 amps.
#6 = Steep = 6 volt/100 amps.
b. Position 2, Material/Wire Diameter (Must be
Set). In this position you set the wire Material type
and Wire Diameter. These selections will be dis-
played in the IPM and VOLTS windows respec-
tively, and are set as follows:
(1) Material. This parameter is set in the left (IPM)
window and displays one of the three avail-
able wire material type code numbers that can
be used (for each torch), and is set by operat-
ing the IPM Inc./Dec. toggle switch. Material
code "1" is for Carbon or Stainless Steels,
code "2" is for the 4000 aluminum series, and

code "3" is for the 5000 aluminum series of

(2) Wire Diameter. This parameter is displayed
in the right (VOLTS) window and offers a
choice of five (5) wire diameter sizes which
can be used (for each torch), and is set by
operating the VOLTS Inc./Dec. toggle switch.
The wire sizes available are: "30" for .030" dia.
"35" for .035" dia., "45" for .045" dia., "52" for
.052" dia. and "63" for .063" dia wires.
c. Position 3, Spot Time/Burnback Time (Optional
Setup). This position allows you to preset either or
both of these welding features for either or both
torches. These parameter times will be displayed
in the IPM and VOLTS windows respectively, and
are set as follows:
(1) Spot time. If a timed weld is desired, a time
from 0.1 to 99.9 seconds can be set in Spotweld
timer (IPM window) using its Inc/Dec key.
Once set, both Schedules I and II will become
"timed" or spot welds. To return to "continu-
ous" welds, the time has to be set to zero (0.0).
When a spot time is programmed for a torch,
the "click-click" the torch switch feature for
changing schedules cannot be used.
(2) Burnback Time. At the same time, you can
also preset a manual Burnback time. The
Burnback time is adjustable in one cycle incre-
ments (60 cycles/sec.) and is programmed in
the VOLTS window using its Inc./Dec. toggle
switch. When preset, the Burnback time will
override the automatic adaptive anti-stick fea-
ture. To resume automatic anti-stick opera-
tion, the Burnback time must be set back to
"zero" (0).
d. Position 4, Schedule II/Schedule II (Optional
Setup). This position allows you to preset a sec-
ond welding schedule. The wire speed rate is set
using the left Inc./Dec. toggle switch and the
setting will appear in the IPM window. The arc
voltage is set using the right Inc./Dec. toggle
switch and the setting will appear in the VOLTS
window.
e. Position 5, Preflow/Postflow (Optional Setup).
In this position (5), Gas Preflow (.1 to 99.9 sec.)
can be set by the left Inc./Dec. toggle and dis-
played in the IPM window. Gas Postflow (.1 to 99.9
sec.) is set by the operating the right Inc./Dec.
toggle and is displayed in the VOLTS window.
These features are adjustable in 0.1 second incre-
ments and are shared by both welding schedules.
