Hi. I have a Bernzomatic torch that takes two disposable tanks, one oxygen tank, and one propane or MAPP tank. This torch is advertised as being able to cut steel, but the link for "CUTTING" on the Bernzomatic website is down. On a standard oxyacetylene cutting torch, you preheat, then hit the lever when the steel is hot to start cutting. But, this little Bernzomatic torch does not have a lever. Do you just heat with an oxidizing flame, then shut off the fuel gas when things get hot? Does this create a potentially dangerous "pop"? Has anyone tried cutting with one of these little things? Aside from the oxygen consumption, did it work OK?
Thanks, Eric
