the acetylene/atmospheric system or the propane systems which look
to need oxygen....
We tend to agree with Ted and like using the propane oxygen systems.
They burn cleaner and have plenty of heat.
OR the Swiss Torch set in Rio's catalog
This a great torch, it runs on Propane or Natural gas and Oxygen or
compressed air (there is only one head that will work with
compressed air though, so that may be a little limiting). Using
oxygen with interchangeable heads, you can go from jobs needing
needle size flames to casting platinum. It's a very versatile torch.
I hope this helps. If you have more questions, call us, Live chat us
via our website, or email us and we'll help in anyway we can. We
also have quitea few videos on torches on our website, so follow the
link and click on the "Video, projects and more" tab. We're about to
release a Soldering 103 video were I talk about the different
torches, so look for that soon.
