I don't braze often, but occasionally I come across some cracked cast iron
or a copper pipe in the house needs to be fix (improved?).
What's a good, all-around choice rod for brazing?
On eBay, I've found some Bernxomatic rods:
1) the Blue NS-3: http://tinyurl.com/3a4y57
2) the White WB-5: http://tinyurl.com/2povjp
What about brazing steel? Does anyone have experience with the Bernxomatic
SWR-10 rods?

As far as I know, Bernxomatic might be a sucky brand! Looking to build on
the experience of others before diving in.
One of these eBay orders for 15-20 rods would probably last me a year or
two. Do these need to be kept in a rod oven like 7018 electrodes?

I buy low fuming bronze brazing rods in 1/16" locally, and heat them and dip
them in a can of blue flux when I'm using them. The bare bronze rods do not
need any special storage, nor does the can of flux.

Thats piqued my interest I think I remember by late father stick
brazing with an old (even then) arc welding plant the sticks had
a coating presumably flux is that kit still available?

Please log in for more thread options It has been over a month and I never got a response. Maybe it was deleted
because of that spammer. Anyway, I'm still curious to learn an answer.
Thanks!

Bernzomatic makes OK stuff, but it is a bit pricey because they sell it
in small quantities.
It is meant for hobbyists.
The differences in the flux color on the rod is because of different
working temperatures, and rod alloy.
According to the Berzomatic website the blue NS-3 is a Nickel silver
rod, stronger, but also requires a higher temperature to make it flow.
The WB-5 is a standard bronze brazing rod.
Easier to work with, lower flowing temperature, not as strong.
You can buy comparable rods at any welding supply store, but usually in
larger quantities.
I prefer to use separate rod and flux.
It allows me to control how much flux I use.
You buy standard Low Fuming Bronze brazing rod and a can of flux powder.
Warm the end of the rod with the torch and dip it in the flux.
The flux will melt and coat the end of the rod.
A good basic flux is Peters No.2 Blue.
It works well for most steel brazing jobs.
They also make a black flux for higher temperatures, which works well on
cast iron.
