I started with an O/A setup but I found it too hard to control the

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 .


Another trick with O/A is to use MIG
wire for filler rod. I can weld 18 ga
sheetmetal with mig wire and an 000
tip.

When I try that it cracks right at the weld when I hammer on it -- mild
steel "gas welding rod" does fine other than being BIG.
