A.4.1 SELECTING A STARTING WAVE SHAPE

When customizing a waveform for a specific welding application, we recommend that you use a waveform in an existing weld file. An existing weld file can be selected from the systemWeldFiles folder in the Wave Designer directory as follows:

a.Click on a standard wave shape from the systemWeldFiles folder. Use the load file option in the File menu to download the selected file to the Pulse Waveform Editor.

NOTE: The welding machine’s controller memory is allocated 10 weld mode slots (modes 155 to

164)for the storage of custom weld designs. No more than ten custom weld modes can be downloaded to the welding machine. You cannot upload a custom weld from the welding machine, but you can overwrite any or all of your allotted weld file memory locations.

b.In Waveform Editor, select the Save Waveform As ... option from the File menu.

CAUTION

Failure to use the Save Waveform As... option to copy the standard wave shape will result in changes to the standard wave shape. Make sure you assign a unique file name to a copy of the standard wave shape before making any waveform changes. Make backup copies of all original wave shape files as well as the custom wave shapes you create.

c.When prompted, type in a unique filename for the new waveform. Select OK to assign the new file name to the waveform.
