6:40 he states the cylinder needs to be opened slowly to prevent damage to the regulator, it is also important to slowly open the cylinder to prevent Regulator Blow Out, where the friction and heat of the gas causes the regulator blow out with tremendous pressure and explosive force and flame......that is why you never stand in front or behind the regulator, only to the side, preferably with the valve between you and the regulator.....look up RBO on the internet, there are some good videos showing the results of opening the oxygen valve to fast....
Helpful tip: when assembling any threaded connection - even nuts & bolts - turn the threaded fastener or fitting counter to the tightening direction of rotation until you feel the sets of threads on the items to be joined "click" into alignment with one another. then rotate in the direction of tightening as usual. This is to prevent cross threading & stripping out of the threads. I learned this procedure in Navy Basic Training, & It's proved most useful. Strip the threads out on the only available firefighting equipment on a ship while it's burning & you're gonna be real unpopular with your shipmates, just before you're all either burned up or drowned.
When charging regulators the user must stand with the cylinder valve between the user and the regulator. This positioning will help protect the user should an regulator incident occur. Also soapy water used for leak tests must be oxygen compatable such as snoop. Common soap/deterget can build up over time creating a flammable buildup on the equipment.
The acetylene connection at 10:30 ish didn't stop leaking completely. What's the procedure if it doesn't stop leaking, you can't just keep on tightening, you'll damage the seats then. Might already be damaged and that's why it's still leaking
They mentioned an AWS (American Welding Society?) RG-60 carbon steel rod at one point. I have some RG-65 rod, which may be mild steel - not sure of that though.
What a great lesson. This is a fantastic way for people like me to learn the basics of welding. The fact that you assume no knowledge really makes it worthwhile. Thank you
Thank you thank you thank you so little of this is taught anymore and if you did not go to school your really out of luck appreciate these videos very much
Gotta love that Purox W-200 aircraft torch. I have one just like it, as well as the later solid forged brass body version that replaced it not long after this video was made. They are excellent torches, definitely one of the very best models ever made.
They're readily available via Ebay like other Purox/Oxweld/Linde/L-tec/Union Carbide/ESAB torches (talk about corporate reorgs!). The 1939 (get none later) edition of the Oxwelder's Handbook is cheap and worth owning. It shows all of them.
I been using Oxyacetylene equipment 21 years and must note one safety tip, ALWAYS use reverse flow check valves and flashback arrestors if you're torch don't have them you can purchase them at the welding supply.
I am not joking. I used the same bottles for over 15 years in a factory. This is the first time i have ever seen a solid steel safety cap that gos over the top like that one. I always assumed the threads on the bottle was for refilling purposes.
12:45 very good description of shut down, so many weldors get bent out of shape if you mess with their settings.... I guess they are not smart enough to remember or record the settings for future use......and they would rather have damage done to their regulators instead of properly shutting them down not to mention the possibility of having a accident ....
Too bad the sound is only in left channel. Next it would be ideal to convert the track in mono 25:27 "it could be eclipse?" "nah. nice try tho" lol 1979 blooper
Brilliant videos. This is just how I was taught OA welding in the 1970s. Once you learn how to control that pool, you never forget! Thank you. Do you have any on OA cutting?
5:20....states that putting a hose on a regulator with something in the hose could let that object be blown into regulator....how could that happen, as the regulator does not suck material in from the hose, it only allows pressure into hose...
Very thorough and covers many aspects that are often overlooked. It sounds very old school, but highly informative. The two commentators with one person asking "dumb" questions and the other person explaining is something I have not seen before.
Mending two metals into one ok mig Tig stick and flux wire almost like mig but diff. And I'm off cool video oxyacetylene welding came aft old school welding and to what we got today in welding
I learned that it was awesome in school what type of school not saying . Tig was born lol anyway subject off . If no electricity was available one had to weld with gas oxyacetylene welling robotics came later . Subject off good video
In this video, and also in my "Oxy-Acetylene Weldor's Handbook", also from the 70s, they open the oxygen tank first, then the acetylene tank. In a newer dvd I bought, and in other youtube tutorials, it's "A before O, or up you go," in other words, acetylene first. Can any pros comment?
The tank and regulators are opened in oxygen then acetylene order. I don’t know why, but have seen this consistently. At the torch end, start the acetylene first, then add the oxygen. This allows you to start a controlled flame with atmospheric oxygen, then boost it with bottled oxygen.
It doesn’t really matter but the Oxygen bottle (what we call them in the UK) is actually more dangerous than the Acetylene. We use PTFE tape on the thread to make sure there is no leakage but this is mainly used for burning as TIG is used now although I can OA weld
The production quality is laughably bad (I thought it was a parody at first) and I could live with that if the info was consistent and up to date. Unfortunately in the beginning of the second segment (about 14:02) he opens the tank valves and the pressure shoots right up in both gauges = the regs were never backed out when the bottles were shut down previously. This comes right after the first segment tells you to *never* do that. Unfortunately it's not funny enough to keep watching as a clown show, so I'll never get to see the rest of it. How does it end? ;)
boostismagic the audio seems to be biased to one side. Unfortunately, if you get it sorted & can hear it, you have to put up with the "8 bit video game" bumper music between segments... ...but you do get to hear Beldor Conehead narrate the second segment. Which is AWESOME, and (all goofing aside) has some real solid info.
6:40 he states the cylinder needs to be opened slowly to prevent damage to the regulator,
it is also important to slowly open the cylinder to prevent Regulator Blow Out, where the

That is good advice. I've been doing it for years, not sure if I figured it myself or learned it from someone else.

Also soapy water used for leak tests must be oxygen compatable such as snoop. Common soap/deterget can build up over time creating a flammable buildup on the equipment.
Ivory was specified by Linde and others in early tech data.
Excellent presentation.
Thanks for posting this

John McDermott more banter @ 25:25...

I suppose the one thing that dates this is the lack of flashback arrestors on either the torch or regulators, not even check valves.
The fitting might need to be replaced.
I also saw that!!!
Thanks. It is amazing. I got a lot.
According to OSHA regulation(s) you are required to have Flashback Arrestors. You are missing this in your procedure.
I also noticed the lack of them!!!!
Perhaps they didn't exsist in 1979?
Excellent. Only some bad teachers could thumb it down.
2020 and still useful
My teacher was hard core welding . Welding metal with heat and it not brazing
Annoyed Norm Macdonald teaching us to weld.
do you have stick welding of this series
Audio is only on the left channel. If you don't hear it, check to see if your balance is set to full right.
Thank you! I thought my new ear buds were broken!
Before that was heating metal the old fashioned way heat y'all know this by now it old school welding even if no gas was available
huh?
Welcome mga BSMARE ng MISAMIS UNIVERSITY!
What filler rods were used?
They mentioned an AWS (American Welding Society?) RG-60 carbon steel rod at one point. I have some RG-65 rod, which may be mild steel - not sure of that though.
@@firstmkb Thanks
Great video to make you doze off.

Oxy acetylene welding is still taught in aviation maitenance schools, aviation is one of the few fields that still use it.
Love the tie under the coveralls ! Great video lesson.

I think they're mostly for transport.
So good. Thank you very much for putting this up, a lot of precise information.

UNTIL THE FLAME BECOME BUSHY
Best instructional video I've seen in a long time, thanks I was getting rusty.
GRIZZ 357 b
If you need a new idea. read an old book
That advice never expires
Absolutely brilliant I have learnt so much from watching and the questions were spot on. Thank you 😊
I like how they teach us like we're idiots, it makes it so much eaier to understand.
"Like"
i hope you add more classic video about fabrication and welding with best wishes
Using ivory soap for that leak check??
I wish I had the voice of the guy asking questions
The OG version of TIG
That music was painful
Is there such a thing as a dumb question, yeah !!
Can anybody compile these types of archival videos technical type. It will be useful for all
Wow nothing has changed sincen 1979 or 1987 i forgot. I just did welding the other week and basically the same procedure in 2019
Mending two metals into one ok mig Tig stick and flux wire almost like mig but diff. And I'm off cool video oxyacetylene welding came aft old school welding and to what we got today in welding
Great antique stuff - I found the detailed flame adjustment section very helpful.
I learned that it was awesome in school what type of school not saying . Tig was born lol anyway subject off . If no electricity was available one had to weld with gas oxyacetylene welling robotics came later . Subject off good video
Really informative. thanks for uploading. please upload videos for arc welding also.
Main point don't over tighten. A lot of gas is lost by not checking for leaks
It's very very nice to learn new skills and useful
best tutorial!!! thanks for share!!!
this is great I would be glad if you write some description about this......add more like this
....do not use oils, but check for leaks with soap?
Probably the soap with no organic (animal) oils. I am not sure 100% so you check it elsewhere. Some soaps are allowable.
Just what i needed!
Greetings,
Jeff
thanks for posting this very helpful video. any chance of part 2?
Eddiemcg th-cam.com/video/Q7Vv_gZfHgo/w-d-xo.html
cool !!!
I love this Vedic tip...I learn a lot from it
this was the best i have look at.
Excellent. Greatly appreciated.
Great Basics Thank You

not a pro but it dosent mayyer
as the final ratio will remain same

good one.
Theis is videos very good
Excellent.
very nice
thanks again

I noticed the regulator issue also.
Lots of great info for beginners at least, and when was the last time you saw someone weld wearing a tie?
Is it just me, or is there no audio?

Take a drink every time you hear “what’s happening now”
Damn this video was made in 1979 older than me ...lol
