For those starting out in HVAC, this is a poor example of brazing practice. No PPE and no demonstration of brazing techniques. And it's not funny to allow fire to burn, but then surely the dimmest idiot knows that (pity these guys dont)
Hey, I just enrolled in HVACR Technician school. Love the work & it's a good career to get into. I look forward to your vids and appreciate your help & knowledge, thank you.
Cool video. I've found some trouble with sprinkling water around the joints too quickly after it's done sometimes starts to temper the joint and copper and make it hard and brittle. I've only ever had it happen once but I'm sure it was due to me getting some cold water on the hot jonit after brazing. I think it's pretty tough to do in this trade, and more critical where strength of steel parts is required not copper tube. Cheers dude. IC.
If you want to change stuff and be able to work in the liquid line, you have to front seat the liquid valve to make the compressor goes into vacuum and when its at zero stop the current right ?
Banging on soft copper to wedge that discharge line back in...I wouldn't wanna be your customer. What about the wet rags on the filters bro, sensitive ain't they? Braze the female end of the joint 1st, if you braze the smaller pipe first your expanding the wrong tube. Right Butthead? I know I know u got the job done. Do it to it
studpuppy69..looks like to me the idiot had his flame waaaaaaaaay to high and the the killer..cold ass water to cool it down..dammit sun...that a'int the way to git-ur-done!!!
lol your a fag--fag why dont you go sit under a rainbow and write a poem. "DONT HAVE FUN WHEN YOUR WORKING WTF" hahaha You know what gives that trade a bad name?! A/C Techs that think they are god and have an attitude like no other.....and I assume you are one of those guys. That or you work at McD's and have no fuckin clue what your talking about.
shut up old man alright--no one cares. If he wants to act like that so be it. To call someone a hack because of how they talk is one of the most ignorant things i have ever heard in my life.....you are childish and ridiculous. You need to give your head a shake bud. Your 55 years old, maybe you are just little out of touch with society.
Yup. On those cube style resi units (Like Goodman Desert Series) you either hang upside down or take the condenser coil off first. But at least those the torch heats up super quick compared to these larger pipes.
Worked for temper zone in new zealand, who have been making units of all sizes for the past 20+ years. Worked in brazzing line one, and made all the headers, gas and water pipes. Wet rag in certain places will stop the heat from traveling and turning it into a water cooled unit lol Anyways, good to here a guy that loves his trade.
Ha ha, thanks. Yeah it seems that wrapping the base of the pipes near the valve with the wet rags does a good job stopping the heat from cooking the valve.
@27five i was brazing units at work and i needed to put wet rags propably 3 inches away from my fitting it seemed it was a little harder to get the right temp on the copper do you think it was the wet rag or the fact i was afraid to overheat the copper?
Thanks. That guy sort of came form nowhere. I almost wonder if it was some dude from the last resi company i worked for trying to talk sh*t or maybe some dude just decided to talk crap. Who knows. I didn't pour any water down the RV. The camera angle just makes it look like it.
It looks like you replaced more reversing valves in one day at one spot than my company has replaced in 10 years. Strange... Also, nice job dropping water around the rv and probably into the system. Also, way to beat on soft, hot copper with hardened metal. Also, do you REALLY think that HUGE rosebud tip was needed? Also, I'm SURE that the 2"X4" piece of barely damp cloth kept the valve cool. Also, I wonder how fubared that drier is after you brazed it in with that HUGE torch and no water
They were changed out on different units, not all on the same of course. I don't think I got any water inside the pipes, but with the camera angle maybe it looks reckless. That "damp cloth" is several small pieces all soaked and wrapped around the important areas to be a "heat sink" and is known to be better than the "paste". Using a LARGE torch also enables you to get in and out with the weld so there isn't as much time for the heat to draw into the internal parts of the RV.
Also, using a large torch on a filter will get you in and out as well. I haven't had a filter fail yet after installing one. Or a RV or TXV. Now if you're going to use too small of a torch, then all the paste and rags in the world wont help you because you'll be spending all day welding that part in. :-P
LOL! The guy probably uses a Turbo Torch that takes 5 minutes to weld in a part. Then talks crap about a Rose Bud on a REAL oxy/acc torch! The wrapped paper towels also kicks butt over paste or a heavy wet rag.
Purging with nitrogen during brazing, evacuating the system properly and a new filter/drier will not cause any problem with moisture in the system.
Just because of using the large torch and the fact that the line has been brazed before, the brazing only takes a very short time. I don't think the filter/drier will be very hot after that.
Did you hear me say "Too Easy" (at 1:30-ish into the video) when they went in like that? I've done MUCH harder than those! Like ones I need to hang up side down to do!!! :-o
Hmm... you know that's a good question. Honestly I never hear anyone talk about purge while UNbrazing joints. But to be honest I don't usually (but I try to cut components out) and I guess if you create oxidation during brazing in parts, you can when unbrazing as well. However, after UNbrazing you can just blast nitrogen through the system and that should blow out the black ozidation where the part is removed. You don't have that option after brazing in the new part, so purge keeps out the O2
The teardrop, LOL! The cool thing is this was not VIRGIN copper I was brazing. It was copper that I just pulled out of the old RV. Jammed it into the new RV and let all the old sil-floss and new sil-floss flow together. Flow is the key. :-]
Thanks. It only took me a week to finish the video :-p I've been slacking on the videos. They were sitting dorment in the Windows Movie Maker screen for a week until I came back and finished it. I may have more clips to edit and upload from various videos I've saved.
No doubt. Especially when you've crawled down INSIDE the Trane Voyager and you can't get away from the odor fast enough! :-0 But I recovered these units pretty good and didn't have that problem. Just all the oil trapped in the discharge line that's shaped in a "U" that holds several ounces of oil.
I was showing the video to a friend today and as he saw the flameage he says "you shoulda put some Beavis and Butthead noises there" and then no sooner he hears me start doing the impression in the video. It was funny that he thought was I was thinking.
I call unfair. You speeded up the video and edited it.

@Master8laster The rags might have been a bit to close, place them a little further away, it'll keep it cooled enough and safe to braze.
