A.2 GMAW PULSE OVERVIEW
Figure A-1 illustrates the variables of the GMAW-P welding process. Each of these variables can
be programmed into a weld table using the Wave Designer software. Figure A-2 shows how the
pulse waveform and the primary variables shape, detach and propel a weld droplet across the
arc.
For more details on each of these variables, refer to Primary Pulse Waveform Components
and Secondary Pulse Waveform Components in paragraphs A.5 and A.6 of this appendix.
