Tinning Flux vs. Standard Paste Flux

[blueman]

I noticed at Home Depot that they sell an Oatey branded "No. 95
Tinning Flux" that supposedly "pre-tins" the pips and prevents the
flux from burning out or the pipe from oxidizing ("turning
green"). They say it is especially good on larger pipes.

Has anybody had any epxerience using such tinning fluxes vs. a
standard flux like the Oatey #5 Past flux?

- Does it really work better on larger pipes?
- What about on smaller pipes?
- Any disadvantages (other than higher price) to using it all the
time?

[EXT]

My experience with the #95, is that it doesn't really add enough "tin" to
the pipe to be useful, and that it often leaves black burnt residue within
the joint, that sometimes is continuous all the way through the joint
causing a leak sometimes 6 or more weeks after completing the job.
Personally, with either standard propane or MAPS gas, good old-fashioned
solder paste still gives me the best joint when using either the easy to
work with 50/50 lead/tin solder on non-drinking lines or with new difficult
to work with lead-free solders.

I like it because it makes it easy to tell when the joint is up to
temp. As you heat the joint, when it gets hot enough, the flux will
"flash" silver as the fine solder particles in the flux melt. At that
point, I stop heating after 1 or 2 more seconds and apply the solder.
I've not had trouble with it burning or leaking using that technique.

I rarely work with anything bigger than 1" copper, so can't comment on
how it works with larger pipe. The price of the flux is so tiny
compared to pipe and fittings that I use it for everything.

blueman,

Since you did request personal opinions from other homeowners, I will not
address any of the inaccurate statements made in the previous posts.

As it states on the Oatey web site:

Standard No.5 flux is intended for soldering copper joints using leaded or
unleaded solder.

No.95 “Tinning” flux is basically the same compound as No.5 flux, except
that it contains small particles of silver solder. These particles help
improve the flow of silver solder.

Since No.95 flux can be used for standard soldering as well as for silver
soldering, Oatey markets it as a dual purpose product .

BTW: silver soldering requires higher temperatures than standard soldering
and therefore tends to oxidize (aka “turn green”)

blueman, since you didn't represent yourself as knowing much about
anything, I'll pretend you didn't reply to a post dated June 23, 2008,
12:08 pm. If you want to learn, get off that stupid web sight and look
up "usenet". Study it well, then maybe post if you can find something
interesting from this decade.

I've had good success using the 95 flux for pipes. Ended up putting some on
a PC board I recently cooked up, and it tinned the copper traces with just a
touch of the iron.

Their product sheet says not for electrical parts. While it will do a good
job of soldering, it leaves behind a residue that will in time draw moisture
out of the air and corrode the electronics.

For electrical or electronics you should use the rosin core solder. With
the extra metals in the 95 mix, it may not be compatible with the normal
(not lead free) electrical solder.
If soldering some of the newer lead free electronics, then it will probably
be compatible, but there is still that long term corrosion effect.

Hi Tony,

Nothing wrong with replying to old posts, the internet keeps things for quite
some time, and is searchable, so new information can be added at any point and
still be useful. Also, blueman was the OP, so you're complaining to the wrong
guy. Also, website.

There is no silver solder in tinning flux, only powdered solder. Check any mfr. site.

[DanHandy]

Since lead-free solder is at least 95% silver, it IS silver solder in powdered form, no?

Don't know where you get your info, but VERY FEW lead free solders
have more than 4% silver - mostly tin (usually more than 90%) and
antimony Copper, Bismuth, Cobalt, Nickel, Indium, Zinc, Germanium

Probably he is confusing the Sn for silver instead of for Tin. Where Ag
is the symble for silver.

The usual was about 60/40 Sn/Pb (tin/lead) for electronic solder before
the lead free stuff came out.
