B.7 APPLICATION EXERCISE
This application exercise steps the user through the development of a basic PowerWave/STT welding program using Wave Designer. Your application most likely will vary from this example but the concepts outlined are recommended for all development work.
If you would like to follow along with this example, use the following set up:
Machine: PowerWave/STT, PowerFeed 10, Magnum 400 gun and cable, miscellaneous other parts to complete welding cell (The standard PowerWave does not have an STT capability. Be sure to use the STT output stud on the STT power source.)
Wire: 0.045
Gas: CO2
Computer: See Section 2 of this manual for minimum requirements and connection diagrams. Click on the Wave Designer icon to start the program.
For this example, we developed a program to weld 16 gauge fillets and lap welds at 130 in/min wire feed speed. The user may want to develop more workpoints for practice.
Before starting the waveshape development process, confirm that the consumables are working properly with the welder. We recommend using a standard waveshape such as mode 5 to confirm that the welding system performs under normal conditions before attempting to develop waveshapes.
1.Select a wave shape. (From the tool bar, select ‘File’, ‘Open Waveform’.) For this exercise, select the “AST452CF STT Fillet Steel 045 CO2 mode.swf” (Wave Designer with Windows 95/NT supports long file names.) The STT Waveform Editor window is automatically displayed. Generally, the user should choose a waveshape file that has the closest welding performance to the intended application.
