where do you get safety silver

[that4byguy]

is this something to get from a welding supply shop? And what do I ask for? Thanks

Welding supply stores will have it. Safety Silv is the product name Harris uses. Any high silver content solder for brazing will work though. Just tell them you're brazing steel together. Make sure to get flux with it.

I get mine at a welding supply store, but you can find it online. Ask for Harris Safety Silv 45 or 56. The 45 is a little cheaper and works just as good. Make sure you get the right Harris flux as well. A 1oz. roll of the 45 is about $18 but it goes a long ways.

You can go to lowes or home depot and get brazing rods that are already flux coated.

Is the difference between 45 and 55 the silver content? Or a number to go with a melting temp? And can you use like a mapp gas or do I need to use oxy/axy set-up? And thanks for the help.

you can use a mapp gas, not sure on the difference between the two numbers are for though.

Yep, that is true. They're a lot cheaper too. But for this particular application, Safety Silv is a far superior product that is well worth the extra investment. It flows much better than rod at a slightly lower temperature, and it doesn't spatter all over everything like rods are prone to do, so your clean-up time is reduced substantially.

Yes, the numbers refer to the percentage of silver content in the alloy.

MAPP can be used, but IMO it takes too long to heat, and the torch tips are too big. But for builders on a budget it is cheap, easily attainable and it will do the job. I prefer an oxy/acetelyne rig, I can use the smallest brazing tip I have and get fast heat in a small concentrated area.

One advantage of MAPP is you won't accidentally burn holes in your tubing if you let it get too hot, like you can easily with oxy/acetelyne if you don't pay attention...
