I started with an O/A setup but I found it too hard to control the heat and
anything I tried to do which was thin would warp badly.


Oddly enough I can hammer-weld sheetmetal parts with O/A, but so far my
efforts to wire-weld bodywork has been a disaster from start to finish.
Of course buying a welder and really practicing with it may help .
