In one of your answers to a pulse TIG setting question you said "If you find one please let me know."
Disclaimer, I am not a full-time welder, just a gunsmith who recognized that TIG was the way to go for welding small gun parts.
My Thermal Arc Pro Wave 185 TSW came with a laminated sheet labeled "185TSW QUICK SET-UP GUIDE" that has a few settings listed as a guide line for machine set-up, which I copied below.
