4. “Go Figure” / Make the Waveform Synergic
Weld synergy is established by shaping the 2nd and all subsequent workpoints. Being synergic, the waveform parameters automatically adjust to programmed data table values. The data table values are unique for selected wire feed speeds. Thereby, the output of the power source changes in response to changes in the wire feed speed, as controlled by the Invertec’s WFS encoder setting. The process of making the waveform synergic involves two procedures; developing the 2nd workpoint and workpoints interpolation.
Developing the 2nd Workpoint
Develop the second workpoint in the same manner as the first.

Workpoints Interpolation
After shaping the second waveform, open the workpoint editor and click on the 
button. Wave Designer interpolates the waveform parameters for each selected wire feed speed between the first and second developed workpoints. These steps can be repeated multiple times to fine tune all the workpoints. The set (fixed) wire feed speeds are those indicated (checked) in the workpoints listing. Go Figure will interpolate/extrapolate between/from set workpoints.
