Thank you sr lucas

Thank you for your nice tips

You should repost this and consider performing it again with updated video equipment. As per the overwhelming response from viewers--this is the best demonstration of capillary action ever made.

Do you get a leak stop that you can inject

as per section ix brazing operator how much length need be qualify ?

Where to get them

How can I contact with you?

That was literally step 8-10 😂

Awesome and helpful

I want to braze copper to a truck chassis. What type of copper do I need to use?

That joint looks terrible

Will this work on cast aluminum ?

Grande

thank you

He÷y im still struggling broe

I guess hvac is much different. This looks wayyy too much flux. I was taught i had to clean the excess flux on the outside only keep it inside and avoid get it inside the tubes.

Put pressure in it and prove your repair.The thing is with aluminum No matter how good it looks you put a pressure in it and you will see it's still leaking.

Maybe someday they'll come up with something that actually lasts. This won't. None of them do, that I've found, can handle #400+ for any real length of time.

Well, there's 11 years of testing. How did it do with R-410a on the high side at 400+?

am i the only one who saw that he actually melted the alu pipe?!

Quick and easy enough reasons for doing things

For the filler metal can I use flux core 0.030, and thank you the answer I'm just starting.

Need Al 822

I think there is still a pinhole in his repair.😁

I have used this particular product. It works quite well. I have also used it on non-HVAC aluminum repairs. The key to a good braze is a clean surface, no oxide and no oils; and heating it to just the correct temperature. Wipe the area to be brazed with a clean cotton cloth that is saturated with acetone. I found it important to heat the repair area just enough to to melt the rod. You also have to make sure that you are not melting the rod with your torch.

what solder L.M. pro lr1 ?

will map gas work?

Looks like a chicken shit on it

Which rod use for brazing coppor to steelness steel sir

I hope you guys know that this is only for new installs that have factory leaks. Why do you think there is not 1 video of a real world leak repair of a coil that has had refrigerant oil ran through it. It can not be done. Don’t waste your time and the customers $.

i work in HVAC manufacturing and we braze the brass valve ports or valve body’s to copper on the Switch Over Valves. sometimes it looks beautiful and sometimes i can’t seem to make the alloy bond to both materials

Poor video: no mention of correct shade of eye protection, too much heat making the copper dead soft by extended annealing, wrong type deep seating plumbing fitting, no mention of oxidation inside the tubing, no mention of nitrogen purge requirements, no mention of...yada yada. Rediculous video.

Good, ty

How about copper to steel

Great video, thanks.

Thanks a lot, I am so impressed and happy, you made my day

What kind of solution we must use to clean tubes after brazing?

Not worth the time life I’ve never gotten home where it that easy to repair copper coil,are easier thats all there is to it

I’ve use this stuff and it does not work like that plus most the holes are mid coils

I've been soldering for 15yrs in a laboratory setting where our copper sees huge swings in temperature and pressure and holds up to this day. This is a very sloppy plumbing job, the extra flux can cause the joint to fail and develop pinhole leaks after some period of time. All that extra flux gobbed on is unnecessary. There should also not be big gobs of solder around the pipe that you started burning to black. Excessive and ugly mess. You should just see a thin ring of solder at the joint because that solder should actually wrap around the copper inside the brass female portion to create its seal.

Way too much flux and cooling brass that quickly can cause it to crack

Awesome display of how flux acts

Hi Mr lucas Milhaubt im in South Africa interested in t 802 low temperature aluminium braising rods but cant find them in our local hardware stores need your help tnx brother plz reply.
