That's why I love rainy days because that's when we get the most creative thank you so much for sharing this and taking advantage of your time to improve on your craft those are the people who succeed and love what they do
I'm a relatively new HVAC tech (6mo) and I'm reliable but slow at brazing. I had a challenge from a teacher today to do something really similar. I had good luck pulling the torch away, heating the silfos, and following the torch and silfos to the tubing to "stick" the little melted ball on the hole edge. Rinse and repeat. It was pretty bumpy so I evenly heated to smooth it out. It actually worked really well.
Awesome skills! A trick taught to me by an ex military mechanic was that you can use a small piece of copper to make a patch, they used it on radiators that had bullet holes in!
+Alexander's Refrigeration & A/C Videos I can do this type of repair in my sleep after doing it for close to 20 years. Now I just still enjoy playing with fire. 😆
Amateur here: I have a very small hole in a window a/c copper line. Can I patch the hole with mapp gas? If so, what rod should I use? I plan on recharging with a bullet valve after.
I would really like to know how they make those T joints to the right of your hole - are those extruded or made with a straight drill? Is there a special tool to make the T joints. Any details would be most welcome!
I have a small crack in the liquid line at the bend just above the compressor. tight spot, wondering if I should use 15% or higher and also a jewelers torch so I can avoid over heating / damaging the compressor? Did this happen because the 3 compressor anchor bolts were tightened down too much causing too much vibration on the liquid line.
You’re probably better off to add an extra “loop” to help absorb the vibration, the compressor will move but the discharge line on the higher end systems have at least a large u shaped line between the compressor and the condenser coil
My limited work with small commercial reach ins have been using Staybrite but need to practice with oxygen/ acetylene and get more comfortable with for those sloppy joints and repairs. Thanks for sharing.
used Staybrite #8 for years on installs and repairs melts and flows at 550 deg. as I recall without annealing the copper same strength pressure, tinsel ect instead of using Silfos. I have used Silfos without any flux still prefer staybrite #8 with flux.
@@HVACinSC Thank you, lol was a Chemist for 15 years now I am a Handyman just installed a New 90+ Furnace and Central Air. Just got done installing my line set and borrowed my buddies Oxy Acetylene torches copper to copper fittings. Buddy gave me two types of Rods not sure if I use the Silver Rod for the Copper to Copper or the one that is a bit duller? Have to get Oxygen tank filled in morning? Any help appreciated thank you for your answer. I subscribed.
@@claystone7729 Without knowing what exactly the brazing rods are it's hard to say which would be best. I'd say the one with the higher silver content will perform better but both rods will work fine on copper to copper regardless of composition.
How can we find and fix leak on a pipe somewhere in a house. It can even be under slab but an AC did not know for sure where the leak is. He said the leak is under slab which a lot of people told me not true.
Isolate the pieces of equipment from the refrigerant lines then pressure test each piece to see which one has a pressure drop. If the copper lines are in the slab without a proper sleeve I'd bet they are leaking too. Concrete will eat copper. Good luck
I made a hole yesterday, and had to fill it like in this video. It's holding pressure from an air compressor. Time will tell if it holds at operating pressure.
@MAK Truck Its all good dude. I post my work to the public so everyone can voice their opinions. I'm not the authority on brazing but I think I'm far better than average tech. 😁 It's not very pretty but they usually aren't when you fix a hole this large with only a brazing rod. Not to mention the lack of nitrogen.
@MAK Truck No I can't. I meant it as a compliment. I have seen the time when a guy that repaired a hole like that could get water to livestock until a prettier repair or folks could get heat while waiting till morning to get materials for a better repair. Sorry if you were offended.
@@HVACinSC I really did mean it as a compliment. Sorry it offended MAK Truck. I have seen the time when a repair like that on copper could get somebody water or heat until pipe and couplings could be acquired after a holiday . Again, NICE JOB.

I’m looking at this on a rainy day hahaha

Ninja brazing skills, I love it!
i agree. helpful to see what his flame/mix look like...
Filling holes on a rainy day. Loved it. 👍👍🤘
😝😝😝

Great thing to do when you can apply the patch.
Thanks HD!
That is badass.
Love to see a video of that experiment.
Great video. I am wondering if this method can be applied to a tiny hole on a copper pipe with high pressure. Thanks.
yes but prefer staybrite #8 and a small copper patch, depending on max pressure.
1st year apprentice in Melbourne Australia? Thanks for the video.
What pressures bdo you run on oxygen acetylene. ?
Any tips for getting blid spots
Can you do a comparison brazing 15% silver rod with soldering on a hole with StayBrite 8 + Stayclean? Thanks
Ditto
What’s the brazing rod there? A phosphorus-bearing one obviously, but which brand and type?
@@MarcWh Standard 15% SilFos. Brand doesn't matter to me
Good job I've done a few like that it takes a ton of practice and pulse... Keep up polishing your skills
+Alexander's Refrigeration & A/C Videos I can do this type of repair in my sleep after doing it for close to 20 years. Now I just still enjoy playing with fire. 😆
@@HVACinSC see practice made perfect 😆😆😆😎😎
What rod were you using?
15% Sil-Fos
Thanks
how did you joined those three pipes that are soldered to the pipe you´re fixing??
Amateur here: I have a very small hole in a window a/c copper line. Can I patch the hole with mapp gas? If so, what rod should I use? I plan on recharging with a bullet valve after.
I have the same question
🤔Also would like to know this, thnks nice video.
How do you fix a leaking brazed joint when there is compressor oil present? Just rebraze and hope the filter / drier catches anything?
I would really like to know how they make those T joints to the right of your hole - are those extruded or made with a straight drill? Is there a special tool to make the T joints. Any details would be most welcome!
Same 1/4 hole curse 3/ 8 tube heater exchanger
Cool skills there. Nice video.

That's some good soldering great work
+chris currie Thanks. They look much cleaner with a nitrogen purge.
It’s not soldering it brazing
@SuperAcousticman Bet you're fun at parties... 🤣🤣
can you share which solder this is, link?
Standard brazing rods 15% Sil-Fos
Nicely done.
What brazing rod did you use?
15% Sil-Fos
Hi bro ,How strong can it hold 4 bar above?
It's stronger than the copper pipe itself if done properly.
My limited work with small commercial reach ins have been using Staybrite but need to practice with oxygen/ acetylene and get more comfortable with for those sloppy joints and repairs.
Thanks for sharing.
used Staybrite #8 for years on installs and repairs melts and flows at 550 deg. as I recall without annealing the copper same strength pressure, tinsel ect instead of using Silfos. I have used Silfos without any flux still prefer staybrite #8 with flux.
Be cool to see a video fixing a bad weld once its done
Nice joint, strong . Have down braze joints due to nails by roofers.. Works well.
+Michael Lee Thanks Michael
Good job you always do good work
Can I fix leak with Freon in pipe? Any method?
Yes. If you have the tools, materials, and training.
The rust is on the Solder? Iron is in your Solder?
Not a chemist bud. No clue of every element in these 15% SilFos rods.

How about soft soldering?
How about it?

Good job Bradley me boy. I guess you can't help the moisture, it runs in the family😹
+Jon HVAC 😆😆😆
Looks good!
Thanks 👍
Pretty amazing
I want to see fixing aluminum pipe too
Show off, Nice video.
+Carl McCoy If I wanted to show off I would have used nitrogen to make a real sexy repair. 😆
Thanks for watching.
Playing with fire fun
Reminds me when i used oxy-acetylene torch the first time. Burned a large hole in coil piping.
+Alex Egorov My boss years ago got us to melt hole in the pipe, then fix them. Over and over.
Hell yea me too... I went from just acetylene, to oxy/acetylene. I do a lot of small units so I melted thru a few pencil driers and copper 🤬
I made a hole yesterday, and had to fill it like in this video. It's holding pressure from an air compressor. Time will tell if it holds at operating pressure.
i too like to experiment with shit
👍
Nice job. Not very pretty but quite functional.
+Gary Dudgeon No nitrogen equals impurities in the joint as I mentioned but thanks. 👍

What rod did you use and was it fluxed ?
15% Sil-Fos. No flux
