dude. youll be there all day with no results. those joints were even interconnected properly causing a bad heat transfer. your flame temp is not hot enough. i can guarantee that after that whole can of mapp gas u wasted that the seal would not hold under a vacuum.

I sometimes use mapp gas for repairs but i’ve never had the problem you’re showing.Mapp gas is not supposed to be inverted because it will separate.Its not oxy/acetylene but sometimes it will get you by.Tell us more about the new compound for making repairs.

I am teaching myself brazing for artistic endeavors. A bronze braze on steel is rather appealing visuallly. I do all my work on fire bricks. These reflect heat and the heat splashes back on the work. Copper is amazing in its ability to disipate heat. You need to focus the heat on your joint. Ceramic fiber blankets for kilns or fire brick should do the trick.

Thanks for watching. I’ve still to find an alternative to oxy/acetylene for brazing. I plan to soon do a review on a new product that could revolutionise the entire brazing process. It’s a glue that can be used for copper, aluminium and brass. It’s already been approved for HVAC use. It’s called HVAC Super Pro.

Dr Z,
I just found your videos and love ‘em. Thanks. I saw a few comments about the o2/mapp torches available at home depot. What is your opinion of these for brazing refrigeration copper? I thought it might be a good compact back up if your oxy/acetylene torch ran out on a job. Thanks.

lol. The video is running in like twice the normal speed. I’ll be making a video sometime this week using a great new propane product.
