I am interested in finding a couple of GOOD sources on GTAW(tig). Primarily on parameters for pulse settings, crater fill. The miller syncrowave I have has alot of bells and whistles. Yes, I realize that many of them are not needed in most cases. I also have 5 GTAW attachments we use on lincoln SMA welders which are scratch start. But I am primarily interested in a chart of some kind which gives parameters for various thicknesses and applications in which we can utilize applications for the "extras" that the syncrowave provides. Any ideas?
