Lincoln Electric IM649 Wave Designer - Manual (Page 33)

A.1 APPENDIX OVERVIEW
This appendix provides a series of discussions on pulse wave shaping principles and the
development of custom GMAW pulse waveforms. The contents of this appendix are arranged as
follows:
Paragraph No./Title Contents Description
A.2 GMAW Pulse Overview How the pulse waveform transfers weld droplets to the
weld surface
A.3 Adaptive and Non-Adaptive How WFS and primary wave shape parameters effect
Mode welding
A.4 Pulse Wave Design Process Flowchart and step by step descriptions of the pulse
wave design process
A.5 Primary Pulse Waveform How peak current, peak time, frequency, and
Components background current effect weld droplet transfer
A.6 Secondary Pulse Waveform How ramp up rate, % ramp overshoot, tailout speed,
Components tailout time, stepoff amperage, and background time
effect weld droplet transfer
A.7 Application Exercise Sample development of a power wave welding program
using Wave Designer
