Brazing rods bad quality?

[wr0x2]

I was trying to braze together some bronze today so I could get some practice brazing before my rparts shipment comes in. Well, propane and not even MAPP could get the rods to melt, and the metal was definatly hot enough. I got these cheap pre fluxed brazing rods, should I get something more expensive with a higher silver content (about 4 times as expensive) or am I not doing something right?

get some harris O for copper to copper and some harris 15 sliv for copper to brass or steel

What kind of torch you using?

I found that with a poor torch (one made for propane) I couldn't melt a rod even with MAPP. Once I got a torch made just for MAPP, and with the same tank + rods, they melt in seconds. It could be that your torch just sucks.

When I said not even MAPP, I meant that MAPP was hotter than propane. Any yes, my torch sucks, it's made for propane. If I get a new torch will I need MAPP/oxy or is just MAPP ok? Keep in mind that I'm on a budget here.

i have a few of those cheap white fluxed rods that ya got, they are in the plumbing section i bet, they take ages to melt and at a hotter temperature (if they are the same as i have, good to use on steel and copPer though with enough heat.
try some brown tip 15% solder rods.

just the map gas torch is needed, no oxgen required, thats what i do all my brazing and a few other members, does the job fine and is the cheapest option.
no need to use lots of oxygen.
the map gas torch has a spiral path in the nozel for a hotter flame, you wont even need it to be at the hottest temp to braze copper pipes.
with a gas oven you can even do dd evaps piece of cake.

You mean with a propane camping stove? I use that makes the entire thing heat up a lot faster, because of the mass and it keeps the temp better once its up to temp.

Get a mapp turbo torch it will get hot enough for silfoss.

The first is hotter, the second probably doesnt have the right oriface for mapp. The first will use a lot of O2 and they charge the same for that as they do for mapp gass.

I got mine for $40 off amazon. Its a nice torch, brazes well, and its a lot easier to work with then my old propane, even when using propane fuel.

Also, don't buy a torch that uses O2 if you want to save money. That stuff is as expensive per tank as MAPP, but you get like 1/10th as much per tank.
