Reset follows Program Number 04. To assign Reset to
a Link position, select the function and press Right/In-
crease repeatedly to go beyond Program Number 04.
To assign a number when Reset is displayed, select
Reset and press Left/Decrease.
9. Repeat Steps 7 and 8 as needed to define the desired
function for each Link position being used.
10. Select the Link Position number in the upper right cor-
ner of the display, and press Right/Increase or
Left/Decrease to display the number of the first Link po-
sition to be executed when the program is executed.
The Link position shown when the
Link mode is exited is the first
position executed when the Link
programs are run. Be sure the
desired Link position is showing
before exiting the Link mode.
NOTE
11. Press Right/Increase when there are no parameters
selected in the Link Position display. The repeating
Link mode displays will appear.
12. Press Parameter Select while the repeating displays
are shown to exit the Link mode. The display shows:
” C O M B I N E ” M O D E
U S E R E M O T E T O S T A R T
13. If desired, use the Combine mode as explained in Sec-
tion 5-10. To exit the Combine mode without using it,
press Parameter Select while this display is shown.
The microprocessor control will enter the Ready condi-
tion.
5-10. Combining Programs
The Combine feature is only
available in the following modes:
Automatic, Semi-Automatic 1, and
Semi-Automatic 5. NOTE
The Combine feature uses parameters from several programs
to create a single multi-slope weld program. The first program
defines preflow, initial amperage, initial to weld amperage
slope, and the weld amperage. Following specified programs
provide weld to weld slopes and weld times. The weld to weld
slopes are calculated by the microprocessor control. The last
program provides the final slope, and final amperage and post-
flow values. This is useful in applications using multiple
non-stop passes, such as pipe-welding with the use of a seam-
tracker.
When the Combine mode is entered, three displays are re-
peated in sequence, indicating that the Combine Ready
condition is active. These displays must be present in order to
start execution of the combined programs.
To combine programs, proceed as follows:
1. Be sure one of the proper modes is selected (see Im-
portant block at beginning of this section).
2. Call up the following display (this is one of the repeating
displays explained in Section 5-1F).
P R O G R A M # 0 X
U S E R E M O T E T O S T A R T
3. Press Parameter Select to increase the program num-
ber beyond 4. The following repeating Link mode
display appears:
P R O G R A M ” L I N K ” M O D E
U S E R E M O T E T O S T A R T
4. Press Parameter Select to enter the Combine mode.
The following repeating Combine mode displays ap-
pear:
” C O M B I N E ” M O D E
U S E R E M O T E T O S T A R T
U S E I N C / D E C B U T T O N S

T O E X I T ” C O M B I N E ”
P R O C E S S P O L A R I T Y I S
< X X .>
5. Press Right/Increase, and the display shows:
C O M B I N E P O S I T I O N X X
I S X X X X X X X
6. The Combine position (1 through 4) is indicated in the
upper right corner. The second line indicates what
function (either a program number or Reset) is as-
signed to the position.
7. To change the number of the Combine position, select
it and press either Right/Increase or Left/Decrease to
change the value as desired. As the Combine position
numbers change, the function currently assigned to
that position will be displayed in the second line.
8. To change the function assigned to a Combine posi-
tion, select the function and press either Right/Increase
or Left/Decrease to change the value.
Reset follows Program Number 04. To assign Reset to
a Combine position, select the function and press
