    Thanks 🙏 a million you’re dope!

    Why not just use a simple silver wire to braze? I think those brazing rod even though are effective, I don’t think it’s more effective than a simple silver brazing wire.

    Been in the trade for 7 years plus and just started brazing. Been wanting to have that braze time but never happened til now except for a couple times. Purposely trying to fill in gaps on scrap copper, put in different positions and use various sizes

    To create a nice fillet apply your brazing alloy just after you remove your heat, it will quickly solidify creating that nice fillet at the joint boundary. Penitration is the key, but the fillet is just a visual conformation that you have a good quality joint.

    Thank you

    Common if brazing is tuf then you didn't weld shit

    Has anyone used the Diversitech nitrogen purging tool to flow nitrogen during brazing? I'm wondering if it's a good buy.

    I have found that selecting the correct tip size and setting the acetylene and oxygen pressures correctly makes a big difference in bringing the joint to temperature and getting a good braze. If the tip size is too large or the gas pressures are too high you can easily overheat the metal and melt it. At the opposite end, an undersize tip and low gas pressures may take a long time to get the joint to temperature, if at all. A poor braze will result that may have leaks.

    A high-tech product was born, a high-temperature flame welder that uses air instead of oxygen acetylene. Looking for partners worldwide!

    I want jn HVAC How processes tell me

    thnx so much I've been working for LG for almost 2 years and im just now getting into brazing and this video was perfect and simple to understand great stuff will subscribe 🤘🤘🤘

    I’ve seen HVAC guys replace compressors on a few units and I’ve never witnessed them purge the lines with nitrogen or evac the system and pull a vacuum. Typically they change the part and put the refrigerant back into the system and they are done.

    Thanks! great instruction. Do you have a pdf for the graphic at 6 seconds? or can you tell me where to get it?

    Just use Stay-Brite 8 and Stay-Clean. Most people who braze don't use nitrogen, resulting in soot in the lines.

  16. LazerBeeInNC

    I have a factory joint in a 4 year old unit 410A heat pump that has a small leak. Can this be repaired with Stay Brite 8 or does it need to be taken apart, prepped and brazed?

    I'm sure there are talented DIYers out there that can handle this type of work. With some practice, anyone can blaze copper tubes. Safety first, of course. People often learn from mistakes. Don't be afraid if you make mistakes.

    What is the best rod for vechicle air-conditioning oxy-acetylene gas welding with a t joint

    Nice

    I'm specifically looking at these videos as a refresher before I DIY. My problem is that the reputable companies are solid booked 3 months in the future and aren't taking new customers. The ones that have time aren't willing to do what I want because all they'll get paid is labor. No commission or markups because I already bought my supplies. This isn't rocket science. Purge, Braze it, pressure test, pull a vacuum, charge it, check subcool. Plus, I get to keep the tools I bought for future projects. It's a win-win. I really hate the elitist mentality some technicians have, like other people can't read, watch videos and learn. Guess how they teach people in HVAC school? A lot of reading, watching videos, and a lab to practice what they're learning.The tip about practicing on some copper pipe beforehand is really good advice and a good confidence builder. I've got Argon which I'll be using to purge, since I already have a tank and regulator for it. Another cool thing to try if you like welding is TIG brazing. Check out This Old Tony's videos.
