Best video the most in RUclips fill the joint 10%

You literally showed to copper connections being brazed here.

This video was assigned to study along with material provided..Great video, as a huge notetaker use to be written but also typing this video material was really interesting and well worth watching because I was able to remember what was narrated while hitting stop to continue writting down my thought note to relate to what was narrated...Tone of narration is a big plus for me.Looking forward to watching more.Thank you

what setting do we use (Vapor or Liquid recovery) if we don't want to use the manifold gauges and wanna use a tee or y to connect the vapor line and liquid line to the Tee or Y.

Very infornative..thanks Laurus

Do you have also system reprocess

thank you for the info

So no wet rags on R134a systems ONLY?! Can someone explain this please? What the hell does the refrigerant type have to do with moisture being drawn into the system if what he said was true?

Recovery it mean pumping freon from unit ??

gotta love the stanky 70s porno music

Lot of great free information on hvac on youtube. Free. Nice people who always outdo each other. Who needs to pay for loans to pay back with this group of volunteer professionals

I'm going to explain a couple of things regarding brazing. Hopefully this helps someone. Copper Phosphorous filler rods aren't compatible with steel so this video wouldn't apply for steel or stainless steel. If you're brazing copper and you do a variety of jobs involving different metals, you most likely already have silver solder brazing rods lying around which are all around a better product. Stick with the silver brazing rods instead, your joints will be stronger. When brazing if you don't want to deal with oxides or scaling in copper tubing, an inert gas purge is recommended. It's not a matter of overheating. nitrogen purge is done because the heated copper reacts with the air inside the tubing to form oxides. This is otherwise known as oxidation or scaling. nitrogen gas is inert to copper and doesn't contain oxygen so when the copper is heated the nitrogen gas prevents oxides from forming. The video makes it sound like you don't need flux. You still need flux because it helps create good joints most of the time by preventing or removing surface contaminants. The last thing you want is a high pressure joint failing because the part wasn't properly cleaned or you used oxy-acetylene and contaminated the joint with oxides. stainless steel is very finicky about surface oxides which is why black flux is recommended to properly braze it. Black flux also has a higher protection temperature of 1700 degrees F. Flux for brazing acts as a protective layer to prevent a bad joint. In some cases there are flux products that will change color to tell you when the base metal is ready to wet with filler. Harris sells a product that goes from green to clear when the base metal is ready to braze.

thank you sir

Top quality information and presentation - thank you.

It doesn't look that much more complicated than flying a Flacon F-16.

Before starting liquid recovery process you need to purge pipelines but also recovery machine ,that was not done??? Also purging machine and pipelines on the end with recovery liquid valve still open??? That’s not right?

Thank you

Whats a dvd? Lol

Great vid.

Thank you, TOS is new to me

Soldering, brazing, and welding are all methods of joining two or more pieces of metal and selected other materials. They are also methods used to fill gaps in metal parts. In welding, the two metals (or thermoplastic) must be similar. For example, copper cannot be welded to steel. Welding uses high temperatures to melt and join two metal parts. A filler metal is often used as well. When properly done, the finished weld is as strong as the surrounding metal. But if the process is not carried out and the welder applies too much heat, it can change the metal’s properties and weaken the weld. There are several different types of welding, including metal inert gas (MIG), arc, electron beam, laser, and stir friction. Welding is also widely used to slice apart large metal structures by melting through them. ruclips.net/video/EjX_m68LlFc/видео.html

great information ..but 240p??? daamm

I’ve only watched my guide do it a few times but after watching this I feel like I’m a pro

Great video, thanks!

very well explained. thank you for this.

thank you!

Excellent video

Where is the soldering?

Thanks .... Good concept

Excellent info. Thank You !

i do wana pick up hvac tho...im calling tomorrow
