I just got a small oxy-propane torch, I have oxygen and am just off to get
some propane, and it occurred to me - do I need dark glasses?

I have safety specs against impact and so on, but not against UV.

Thanks,

Simon writes complaining about the term "titsup" (Letters, 18 Jan). His
assertion that it is a reference to female mammalian anatomy is mistaken. It
is an American term, derived from "catsup" ("tomato sauce" in English). A
lighter, sweeter variant was developed for use on desserts, and named
"titsup" after the small bird (a favourite snack for cats.) Americans use
titsup much like the English use custard, hence the phrase "went titsup" is
the American equivalent of the English phrase "it all went to custard."

Yep same shade shield you use for Oxy Acet. Usually shade 5.

I would think that a prudent person would use the goggles for
oxy-acetylene, which are pretty dark, darker than sunglasses, but not
ridiculously so.

The yellow glow of hot steel does need reasonably dark lenses, perhaps
shade 5 as a start, to give a better view of the area on the metal
itself.

What are you going to use the torch for? Jewelers use oxy-fuel
(generally propane or natural gas) torches and I never met one who used
dark glasses except for melting and for platinum work. For brazing,
silver and gold soldering, etc. on small items, most feel it's not
needed. I don't use shaded lenses except for platinum -- when I'm
melting, I just don't stare at the crucible. For platinum, it's
essential, though, as the stuff gets white-hot. For larger brazing
work, some use shades, some don't. I don't, though I only braze larger
stuff infrequently. The oxy-propane flame is nowhere near as bright
and radiant as oxy-acetylene, so it mostly depends on how hot the work
is getting, and how large the radiant area is. (and how close you are
to it, of course).

UV is not a problem with oxyfuel welding. Shade 5 goggles recommended for
the visible light.

Thanks everyone!

Yes, it's a jeweller's torch, and will mostly be used for brazing small
parts, mostly an inch or two across, in copper, inconel and stainless. I
have some small propane torches I use for silver soldering, but they were
struggling a bit and I wanted something hotter for brazing.

I got it working on butane (don't laugh, I filled two party balloons, one
with butane lighter fuel and one with oxygen, to try it out) - works great.
I am seriously pleased. Working with a flame that's comfortably hot enough
is so much easier! It's lot quieter than the propane torches too, a calm
gentle hiss rather than a whiny roar.

Might try MAPP gas for a bit of welding too. Maybe some ordinary shades for
that? I have a nice dark wraparound plastic prescription pair somewhere, but
it hasn't been that sunny recently in the UK and they will take a bit of
finding ...



One other question you may be able to help with - could I use it for
cutting? It's a Minox torch and says "2" on the copper part of the nozzle.
Would a cutting nozzle be available? Obviously I'd need lenses for that.

Although shade 5 lenses are recommended, I found those bulky, dark, plastic
sunglasses that cover your ordinary glasses work well for me. They are
considerably cheaper than the shade 5 goggles from the welding supply
people. YMMV.
