    If they did, they needed a big cylinder or they would have ran out.

    What I find impressive is that it appears they were able to bridge the gap between the stubs but couldn't seem to fill the freaking joint. Haha.

    His used ox-acetylene kit only came with the cutting torch when he bought it, so a rosebud won't fit.

    I'm wondering if that's silver braze or plumber's solder.

    On a serious note, those who silver braze with ox-acetylene, do you use brazing tips or rosebud heating tips?

    I use a smith mini torch! THe Twin tip on small pipe 3/8, 1/2" ! The C tip on 7/8 to 1 1/8"! The little normal tip for 1/4". The rose bud for RV's and then i have a giant C tip for big pipe like on the big blue 20 ton danfoss below! Here's what the welds look like!

    Is that The Little Torch that's marketed to jewelers or something else?
    Looks like a #0 brazing tip on a full size torch set could do anything The Little Torch could do.

    No, it's for HVAC. It's called Quickbraze! Uniweld makes one too! Basically it's just a small torch handle for tight spaces. And some cool tips to help you out in tight spots!

    :-( We had some experience with Carrier distributor field service technicians, who soldered the leaking condenser coils of our 30gt130-210 water cooled chiller. Will upload the pictures tomorrow here. I hope its ok, even if Im a new member with only 2 posts.

    I have never damaged a reversing valve from overheating, now I guess I know why. BTW this proves that with persistence anyone can do anything!!!!!

    The set I found has a regular brazing tip, one that looks like a rosebud, and two horseshoe or "C" tips that would heat both sides of a pipe at once. Those C tips are a good idea that I'd never seen or heard of before.
