Brazing
As far as I know, those locations will have arc welders and not spot welders.
Indeed.
There are very few spot welders around, maybe in Santiago and Santo Domingo. Even on car bodies they use MAG welding which does not give you the desired results.
But well, maybe some people here regard the common "peek-touch-and-forget" welding as spot welding...
BTW, on bicycles one would prefer brazing for repair work (on the frame).
With spot welding machines the usual thin cables would all melt down..... :bunny:
