7. Click on the button to display the
WorkPoint Editor window. Check only those
wire feed speed points that have been
developed (only 150 in/min. at this point). The
WorkPoint Editor can also be used to change
the wire feed speed value of a workpoint.
Workpoints can have the same value but must
be in numerical order.
Select the button to set the wave
shape parameters for all workpoints equal to
the wave shape parameters of the 150 in/min.
workpoint. Close the WorkPoint Editor window.

Our Experiment: We needed to adjust the
starting variables. With the feeder’s run-in
WFS set at 65 in/min, we set the starting
variables to control the starting routine. With
the assistance of ArcScope, we found good
settings with these values: start volt 21.0,
start time 35 milliseconds, and start current
180 amps. The OCV strike peak time and
amps were acceptable as set.
