Answer:

I think you speak of the Langmuir torch..........

Explanation:

This is not something I have done, whereas I have used an oxy-acetylene torch. The signal advantage of the Langmuir torch is that you can reach temperatures of approx. #3500# #""^@C#, whereas if you use an oxyacetylene torch you can reach temperatures of max. #3000# #""^@C#.

And such a temperature allows us to weld the most refractory metal, tungsten, #"melting point"#, #3422""^@# #C#. This is probably the preserve of a specialist rather than a handyman. Again, I don't know under what circumstances you would want to weld tungsten - I have no doubt that there are some.
