Need info on a good oxy/acteylene set up for brazing

[helmbelly]

That looks like silver solder, not brazing and if your joining Aluminum that is what it is,

That narrows down the jargon. But if aluminum can't be brazed only silver soldered there is whole world of info out there to the contrary. How to reconcile?

Sorry, There are now Aluminum Brazing/gas welding rods available now, I had forgotten those, but what was in your photo didn't look like brazing.

Although this is not aluminum, this is Silver Soldered, this is what it looks like.... The bottom photo was the install of a drain on a transmission pan.

Aluminum can be brazed. I do it quite a bit. I buy the hobart rods you can use propane or mapp. I use mapp for the bigger brazes, when I can't get the base metal hot enough using propane.

So I don't need A/C tig.

yeah that part didn't win the pageant. I gave it to my 4 yr old grandson and told him it's R2D2's friend. "where is his arms?"

Hey, not insult intended, it takes time to learn and figure out new procedures, your working at it and will get there.

wow thats really smooth. do you remember what you used for rod - they tell me for stainless to def use 56 silver. Wondering if that holds true for mild steel as well

Are you using your MAPP and Propane with oxy or just the bottles alone?

Do you use flux with the hobart rods ?

Two thoughts, Check with your local high school I.A. teacher to see if a night class might be available or they might give you some advice. Second, check with any place that rents tools for a gass welding rig. True Value Hardware stores... some have rental equipment, just a tought.

no oxy. And no flux. but you must clean up the aluminum before brazing. No foreign matter.
