Lincoln Electric IM649 Wave Designer - Manual (Page 62)

NOTE: You can edit one or more workpoints to values other than the defaults.
However, the listing of wire feed speeds displayed must be the same or
increasing from top to bottom. All four wire feed speeds must be assigned
values, but multiple workpoints can share the same value.
The reason you would edit multiple workpoints to the same value would be to
limit the range of WFS or to develop fewer than four workpoints.
B.4.2 CUSTOMIZING THE WAVE SHAPE
If customizing your first wave shape, perform the wave shaping exercises provided at the back of
this section to get thoroughly acquainted with wave shaping. Thereafter, refer the following wave
shaping procedure.
1. Select a Workpoint
a. Select a workpoint from the Wire Feed Speed pulldown menu. The first workpoint selected
should be in the midrange of the expected Wire Feed Speeds to be used for the weld
application. If you are uncertain of the WFS range, we recommend selecting 150 or 200
in/min. as a first workpoint.
