12.Open the “Edit” screen and select only those
workpoints that have been developed (150 and
300 in/min.). Select the 
button to interpolate the remaining workpoints. The
function gives a estimation of the values needed for the other wire feed speeds. Each useable workpoint should be developed separately.
Our Experiment: We tested the 205 in/min. workpoint to confirm that its operation was good. We checked the pulse variables in the no adapt mode and the peak voltage in the adaptive mode. The 205 in/min. workpoint was acceptable without modifications. The other workpoints in the program can be developed in a similar fashion. After we completed developing the program, we checked its performance across the range of wire feed speeds.

13.The specific wire feed speed points of the program are now developed in the range of 150 in/min to 300 in/min. Check the full range of the program to confirm its synergic operation.
Our Experiment: We started at 150 in/min. and while welding, ran the wire feed speed up to 300 in/min. The arc looked consistent across the range.
14.If desired, our new custom waveform could be ‘Saved As’ another file name and downloaded into the PowerWave’s weld mode directory.
The new program is complete. To summarize, we performed the following sequence of tasks:
1.Set up the equipment.
2.Selected a program close to our application needs.
3.Selected a wire feed speed.
4.Make program “No Adapt” and set pulse variables.
5.Make program “Adapt” and set arc length.
6.Adjust the starting, shorting, ending routines as needed.
7.Use 
to interpolate and extrapolate values for the other wire feed speeds.
8.Choose the next wire feed speed to develop and go back to step 4.
9.Weld with the range of the program to confirm operation performance.
