STT WAVE SHAPING PRINCIPLES

Appendix B

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.

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.Set the welding machine’s wire feed speed equal to the selected workpoint setting.

c.Verify that the control box Weld Mode is set for an OFF readout at the LED display and that the arc control is OFF.
