Good demonstration! My experience with doing aluminum always turned out awful. The biggest difference I see is you are using a propane torch as opposed to an oxy acetylene rig os heat is more manageable.
Hello again, i can not find this rod anywhere local to me. Is there an alternative rod you would recommend? I have some ER4043, but I'm not sure if it has flux core or not. Thanks again
I found a small leak in the middle of a distribution tube and not knowing better I rapped it with J B Weld Marine but after I charged it it had a very small leak. After watching this video I feel tempted to pull the evap and fix it the right way but Id have to cut like 4 inches where the epoxy is the get a piece of aluminum tube to weld it. What do you think? is it worth the risk?
When brazing an air conditioner condenser, do I need to release the refrigerant gas? As opposed to 'pum- down' to collect the refrigerant gas into the outdoor unit, if I 'pump-up' and then braze, is there a risk of explosion? ( Google Translation Sorry)
@@TaeHo_Park You can't pump the system like you're thinking. If you're making repairs to a condenser you need to remove all the refrigerant and purge with Nitro before you attempt to make repairs. You should also low flow nitrogen while brazing
I just found a small leak on my evaporator in my refrigerator and was not sure how to repair it. Thank you for a great video and complete information.
Hope you get a million views
Nice video!
thanks for making the video
Great explanation

Thank you. Yes I believe that the MAP gas is key for those that are not used to making these repairs.
Rig OS heat = ?

Supply house has it. There's a link.
ER4043 are tig welding rods. That definitely won't work

@@enriquepacheco6545 depends on how patient you are. If you are confident you can get all the JB weld off, then I would.

You will begin to see a red "corona" in the flame as the aluminum comes up to temperature. You see red in your flame, dip the solder!
Good idea
Nice one man
GREAT JOB!!! WHERE CAN I GET TORCH HEAD LIKE YOURS??
Home Depot or any hardware store
@@0komanji0 THANK YOU VERY MUCH!!!
Hi can you give me the full name of this brazing rods?
Harris is the manufacturer. I'm using the Aluxcor 78/22 rod.
@@0komanji0 Thank you for being so kind..
@@0komanji0, thank you!!!
No, at what time did you say to use flux?
The solder I use in this video has a flux core. You don't need additional flux.
It might have been easier to use the multitude to get a clean-cut for the repair. Less damage to the fins
WHAT'S A MULTITUDE???
He left a big hold on the copper to aluminum. That is not flux .
