Default debating pros and cons of harris 19-6 Torch Handle, wt040018 gloor light torch handle, and smith little torch

im lookingto do a wide range of work with the new torch im planning on
getting and before i decide id like to hear others opinions. im going
to be using propane and oxygen. id like to be able to solder big pieces
and some casting. in mostly silver some gold (and copper and brass).
and id also like to weld. what do people recomend? are there any
warnings? also i cant seem to find technical info on all of them. for
example what is the maximum the harris and gloor can cast? what can the
little torch weld? what are the max temp of the gloor and harris
torches with propane gas?
thanks

You won't be able to weld ferrous metals with propane/oxygen -- it
doesn't get hot enough, you need oxy/acetylene for welding iron and
steel. You can braze them, though, subject to flame size vs. size of
the work.

The little torch will be challenged with anything larger than small
jewlry pieces, and won't melt more than an oz or so of silver or gold
(and that grudgingly). With oxy/propane, the LT is fine for small
jewelry pieces, soldering (brazing) silver, gold, brass, etc, and
welding platinum, again in small sizes, such as ring repair. With
oxy/acetylene, the LT will weld small steel work.

I like the Meco Midget -- wide range of flame sizes from micro to
enough for melting several ounces of metal, depending on the tips you
use. FWIW, I have 3 torches in my shop -- the LT, Meco Midget, and an
acetylene/air torch used for brazing large work, large silver-soldering
jobs, and melting. I've infrequently hooked up the Meco or LT to the
acetylene tank for small welding jobs, otherwise they run oxy/propane.

Bob

Big casting, like a half dozen rings on a tree?
An oxy-acetylene torch, full size, will make your life
much easier.

in mostly silver some gold (and copper and brass).
and id also like to weld.


For any welding I like oxy-acetylene. The flame is much more
concentrated than oxy-propane. Non-ferrous metals tend to get a huge
puddle and collapse without this concentration. Gold
fuses nicely and even with a certain amount of control with an o-a Little
Torch. Silver is always a problem.

But o-a is _not_ the best for hard soldering.
Air-acetylene, propane, or
oxy-propane are best for that.

If you want it all, you'll have to plunk
for three bottles: oxygen, acetylene, and propane. Y-splitter manifolds
will allow you to run two hoses from each bottle for the widest choice of
torch setups.

....are there any
warnings?


Propane will rot some hoses that are not made for it.
Get the right hose. If a hose's packaging says 'acetylene only',
pay attention.

what are the max temp of the gloor and harris
torches with propane gas?


They will burn at the temp of the gasses being used.
Larger tips cover a larger area with that temperature.
Large pieces require large tips.

Don't buy undersized bottles.
