SECTION 3
b. Continue to hold the Purge position for approx. 15
seconds to insure adequate purging of each gas
hose and torch.
5. Place control's Power switch to "off' position.
3.4 SETTING UP WELDING PARAMETERS
A. INITIAL SETUP PARAMETERS
1. Set POWER switch (on rear panel) to ON position to
energize Digimig control.
2. Place RUN-SET keylock switch (on rear panel) to
SET position to program welding parameters for the
torch. After the desired program (following) has been
preset, the operator or supervisor is free to weld and
make any changes is in the SET position. The RUN
position locks-in all parameters.
The following parameters (#3, #4, and #5) are shared
between the two torches and cannot be setup inde-
pendently.
Pos. #6
3. To set a "cold wire inch speed" parameter (op-
tional), open the accessory support (so as not to feed
wire) and then raise and hold the toggle of the INCH-
PURGE switch. (The IPM display window will imme-
diately show a speed setting of 100 ipm for 2-sec-
onds, and then the preset rate following). Now, also
raise and hold the toggle of the "left" Inc/Dec switch
in its INC position until the desired inch speed setting
(e.g.: 75 ipm) appears in the IPM window. Note that
the cold inch setting starts at 40 ipm and rapidly
increments (1 ipm at a time) until the desired setting

is reached. To feed the cold wire preset, you must
actuate the INCH position of the Inch-Purge (Reset)
switch, with the accessory support closed.
4. Set the Rotary switch to Position #1 (Must be set)
to select the Power Source and Slope used for your
welding application as follows:
Remember that this must be correctly set to
match the Power Source being used and its slope
selection.
a. Power Source: operate the left Inc./Dec. switch
until the numeral "300", "450" or "650" appears in
the IPM window. One of these numbers should
match the power source being used: "300" desig-
nates an SVI-300i cv/cc; "450" would designate a
VI-450 or SVI-450i and "650" would designate a V-
650 cv/cc. (see section 3.2-6-a.)
b. Slope: operate the right Inc./Dec. switch to set the
appropriate slope characteristic set on your power
source. One of three slope designations will ap-
pear in the VOLTS window; #1 for Flat, #3 for
Medium, or #6 for Steep Slope. Make sure the
feeder slope number matches the slope se-
lected at the power source. (see section 3.2-6-
a)
5. You can also select (optional) Trigger Lock-In
(see Section 3.2-3A); however, remember when
added ("on"), both torches are locked in.
B. PROGRAM FIRST (e.g. RIGHT) TORCH
After the initial setup has been completed, you can
program the welding parameters for the Right torch as
follows:
1. To set-up the "Right" torch program circuitry,
actuate and immediately release its trigger switch
lever.
2. Set the Rotary Switch to Position #2 (Must be set)
to select the wire Material and Wire Diameter used
for your welding application as follows:
Remember, this must be set correctly to match
the wire material and diameter being used.
a. Material: operate the left Inc./Dec. switch to set
the wire Material you intend to use. One of three
Material designations will appear in the IPM win-
dow; #1 for carbon or stainless steel, #2 for 4000
series, aluminum, or #3 for 5000 series aluminum.
