i was told a long time ago by an old tech to sand where your going to cut first then you wont get the sanded off stuff into the pipe and also always sand back away from the joint and the coupling itself to get it shiny and will accept heat quicker as the oxidation will reflect heat and not absorb it as quicky,to this day is my practice
Absolutely correct assessment. That's exactly how to do it. Curiously to clean a normal wound should be done similarly. Meaning always move away from the wound. So contaminants, dirt and debris won't come into the damaged/wounded area. ;-)
You make it look easy, like you said it's easy when you know how. I consider myself generally good at brazing but patching aluminum is not easy. I wish my company would invest in more products like what you have here. I've made some successful aluminum patches before with different rods but have also failed some too. My company has us use high temp epoxy with a heat gun, have had some hold and others not. Quick tip for epoxy products is to pull vacuum while applying it. I found it helps. Do you have an opinion on epoxy products and have you tried any? Thanks for the video.
Thanks for the video....I have done a couple, like the product, but its melting point, even being low, is still too high for refrigerator or freezer evaporators that someone has taken a sharp object to, trying to defrost it....It can still be done, but blowing a hole in the evaporator is just seconds past the melting of the solder...I think the type of flux should be mentioned too.
There all possible to fix but not practical for most residential units. Once there is a hole in an old coil the integrity off it is gone. You may fix the leak and fill back up... spending lot and then another occurs or that one opens up again. It's best to replace it with new coil and have a 10 year part warranty and full 1 year or more labor warranty. 😎
does it hold for awhile?? I punched a hole in my A/C unit outside my house, ( long and stupid story) trying to find someone to do this and refill with freon as all mine came out :). I'm wondering is this a temporary fix? or will this be good once its done? anyone can answer if you have a idea
Learn english and you wont have that problem. Why should he change the way he communicates because some people are to lazy or stupid to learn or understand English. So maybe non english speakers having a problem following what hes saying should learn to listen faster
@@channelcatchaser9426 it's not worth it lets say you send 3 to 4 hr repairing old coil $$$$$$ then it leaks in a new spot who pays for it you. No good deed goes unpunished new coil about the same time
Good video👍👍

Question for you, maestro.
Could you also use a solder called “ChannelFlux” along with propane or mapp gas instead of oxyacetylene?
you dont need to keep the adjoining joints cool to avoid them coming apart?
This is a skill ...not to get compensated...wish my boss could grasp that...I'm ready to pull an " office space"....
Thank you. Great demonstration and presentation to go along.

what flux are you using?
This is called............skills.
Good workshop on the aluminum weld thanks for sharing 😎👍😁
500psi, do you have to suit up into bomb disposal gear ?
Thanks for video I never braze aluminum and wanted to learn.
I have a small hole, HVAC tech said not possible to fix, need to buy new coil

@@97Napkins I got a professional to fix it, knock on aluminum.... Been a year so far so good.
@@gwp1ohio congrats... hope all is well for this summer. #Change your filter. 😉
What kind of flux?
Ty always for the videos and I'm years late but man that camera shake when you are asking us to look =b
No complaints and great content.
Cool. I have been using a mapp gas because it burns cooler
I’m having nightmares of the tube collapsing as I heat it.... I swear it looked like that U tube almost started glowing. 😱

What flux was used?
It's a product also made by solder weld
It turns clear at 600°, when you're ready to lay the rod it might come with the kit....
How is this different than Hi-Alloy 129 or Super Alloy 5? Or is it just another product along the same vein?
Great video thank you!
Thanks for the demonstration
What nitrogen manifold is that?
Will be answering everybody's concerns in Q/A video
victor reinz
now that was a really good class
Is there a reason propane and butane are not used in HVAC? They burn hot enough.
butane is a bastard gas
Had a pinhole on the inside of a u-bend. I almost melted a big hole but saved it.
Great Video!
Glad you enjoyed it
If you put that much heat on a micro-channel coil it will go away in an instant. The wall thickness isn’t thick enough on a micro-channel.
good stuffs. Great product, awesome company
these are GOOD videos!!
Great job
Can some one post a link where I can buy this rod please
Cool brazing.
kit part # ?
They never show this stuff when they are in a 130 degree cramped attic space in the dark
Yeah. Just replace the evap at that point ffs
Just use JB weld so much cheaper .
Coil leaks suck.
Yea, but on a good day, so does my priest.
"rub out"
I would had used epoxy to fix the hole.
@@nunyabusiness6746 Yea, I hope no-one took my advise. I'm not a HVAC at all!

QUE DIJO?? NO ENTENDER NADA
Why give such a smart ass answer
Yeah just replace the coil
Sometimes that’s the best option sometimes it isn’t.
That's a big problem with the industry.....no one wants to fix anything just replace it

@@tonyrichards2017 i completely understand but on the other hand skill is lost if trade practices are not practiced.
At this point will be to replaced the coil.
Just kidding
If I tried it you definitely would have to replace it.
nicely done ,,,,,even from a welders point of view LOL ,,,,,,alloys are a bitch they are picky lol
