I have the 325ext and get by without pulse most of the time. When I do need pulse I usually hit Google for some insight and come up short. I guess and try this or that and eventually turn it off lol. Could anyone share some basic pulse settings that work well for them? I've got some .040 stainless projects and some 3/32" and 1/8" 5053 (I think) projects. I've got purple and gold tungstens.
