Section 6 Weld control 37
Options
Each weld program has a number of optional features.
Parameter Range Description
Pre-heat yes/no Enables or disables the Pre-heat parameters
Post-heat yes/no Enables or disables the Post-heat parameters
Pulsations 1 - 99 The number of times the Main heat – Cool2 interval is repeated
Link yes/no The next welding program will be started automatically if the input signals
are maintained
Repeat yes/no The welding program will be repeated if the input signals are maintained
Force profile yes/no Use multiple force values during the weld
Inhibit yes/no An inhibited program will not run
1
1
If an inhibited program is not linked then attempting to run it will produce the error message. If the
program is linked, then the program will be skipped and the next linked program will run. This feature
may be used to temporarily disable a program in a cascade.
Pulsations can be used to temper the material, control nugget growth and reduce electrode wear.
The Start signal must be maintained for the full duration of the sequence if pulsations are set to 10 or
more, otherwise the sequence will terminate after 10 pulses.
Program selection
The program that will be used for welding can be selected in one of two ways
Section 12 Configuration: by using the Program Select inputs (external)
Section 13 Programming: by using the Use Program parameter (internal)
If the external method is used, inputs P1 – P64 correspond to the binary value of the program that will
be used. If the internal method is used, the Use Program parameter determines the weld program that
will be used. The program number can be changed during the weld sequence.
Multi-electrode operation (extended feature)
Each welding program can be assigned an electrode.
Parameter Units Range Description
Electrode 0 - 7 The electrode number
When a program is used, iPAK2 will automatically trigger the correct transformer by referencing the
electrode/transformer assignment as described below. In addition, the electrode number is also used to
access the appropriate stepper, counter and calibration information
