I'm looking at buying a soldering torch that runs on acetylene. I have an O/A setup, so I don't need to buy a tank, but it seems I might have to buy a regulator!
What's the difference between a 30-15-520 regulator and a 101-15? (If that even makes sense?) The Smith 30-15-520 comes with the soldering torch, it's this one
and the one I have is a Lincoln
it came with that portable torch kit from the big box hardwares:
