Used to use it with O/A to weld up exhaust piping.

Gotta remove the protective coating off the wire for best results though.

We broke a track chain on an old caterpillar up on a side hill in the early 70's. Hit up the local farmers for oxy-acet tanks and a coat hanger for a temporary repair. We heated and beat the link back together and my brother welded the link with the coat hanger on the premise of grinding it out and arcing it when we got it back to the shop. Which never happened as 30 years later when it was sold it was still holding!
That just don't make coat hangers as good as those anymore!

So one could say the weld hung in there.
