   I saw a coot that had parts welded with one of them and during
preflight checks the aileron fell of in his hand do to a weld
breakage.
  The weld had no penetration and was just stuck on the surface.
  No substitute for a tig.

the parts demonstrated had beautiful penetration, both steel and aluminum.
you could bend the pieces in both directions and they acted as one piece.
My guess would be that the gentler heat of the torch would actually produce
better welds than the intense heat of an arc, as far as crystallization and
grain.  I'll bet that an inexperienced welder could botch up any kind of
weld.   I remember my first stick weld going through the bend tester like a
piece of glass!
