I've tried all with varying success using slightly different techniques for each. Just curious what people's preferences are.
All depends on the welder..
or are you talking about what setting do I use to perform the plate-to-sheet weld? In that case, it's 'hot enough to melt the plate, not hot enough to burn the sheet.' usually it's a middle of the road thing on my welder.. I'll run the sheet metal current and a lower feed speed so I can get enough penetration on the plate, then just move across the sheet a bit faster to keep from overheating it. Seems to work OK for me. YMMV.
