I've seen those tools you posted but have not used them myself. One of the guys who works for me likes them and gets good results with them so its a lot a matter of preference. I learned the trade doing tons of 365 work at Karosserie Kolbe doing all straight butted welds (there are tons of butted joints on the outer skins of the 356)

I wrote up a big reply at home last nite and never posted it-maybe it will still be there when I get back but I am at my shop now...if its there I will post tonite.

Basically my millermatic 185 set on to run 30 percent of max voltage and 50 percent of max wire speed has no problem with full penetration and working slowly, has no warpage problems that are out of whack from any other welding on sheet metal. In fact, I usually have to dress the hangers on the back side of the weld prior to doing and final hammer/dolly work.

Welder settings are hugely a matter of taste and style. Ditto for basic welding practice. I say if it works for you, do it and have fun!!
