Can you identify this gas torch?

[Grindstone CowboyParticipant @grindstonecowboy]

Can anyone identify this torch please? No makers name but it is stamped HT2/N

It was given to a friend many years ago, but he has no idea if it is oxy-acetylene, oxy-propane or propane/air. Or something else.

He's hoping it's propane/air and is looking to do some light brazing with it, small brackets and suchlike. Obviously not keen just to connect to a gas supply, light it and hope for the best without some clue as to what it is intended for

The control knob nearest the nozzle is marked 'GAS'. Nozzle is approx 11mm across.

Thanks,

Rob

Laboratory glass blower´s torch?

Thanks Dick, now you mention it, it does look similar to one I saw being used years ago. Any idea if that would use propane / air?

Definitely a glass blowers torch. The ones I am familiar with used mains gas and compressed air, but there are lots of variations on that theme.

Age might determine the gas type, if it was connected to the mains. It is marked with a suffix N, so that might mean Natural gas – mostly methane?

Mains gas /air I would think. The valves are nice and fall naturally under your index finger and thumb to switch between melting/burning off, keeping warm to blow and annealing the finished piece. Maybe it predates natural gas. The other usual one was a bunsen type with a heavy stand and the burner angled up at about 45 deg. The one you have was more for working on (glass) vac lines in situ or burning off and sealing a vial of something from a vacuum line.

Many thanks for all your replies, I will pass the information on – I told him it would only take a few hours for the forum to come up with the answer
