I keep wondering if this guy is an actor, or the best technical salesman ever, or a SMITH engineer or what? I don't meet people like this in the welding sector.
I don't think I have enjoyed watching any youtube video as much as I have enjoyed this one. Such a proffessional. Thank you so much. There is so much to learn from this gentleman.
I agree that there should be more of these videos! I check every few months. I have Smith equipment, and am inclined to trust them, especially after watching this one! It's one of the greatest lab presentations I've ever seen!
I am cutting titanium up to 12 inches thick. The man who taught me at my job hardly speaks english. Nobody has a understanding of the torch theyre just doing what they think is right. This was so helpful you have no idea. Im going to do more research!
Airgas & praxair (Army also teaches this) says only to open the fuel gas 1 to 1.5 turns. I asked the fire department about this, they concurred. They went into a whole of reasons why to not fully open the valves, but the two main points I took away from it all was; In the event of a problem, it only takes that much to do an emergency shutdown. And damage/ leaks can occur by opening fully opening the valves, and manufacturers recommend not opening all the way, especially to full open stop. Just passing that along.
This is helpful. I'd love to see another video or two showing how to get a neutral flame with the oxy-propane brazing tips (I have the MW-411) and also the oxy-propane rosebuds (I have the MT-805). Some additional commentary on the propane tank sizes required to run the rosebud for short periods of time (as opposed to continuous use) would also be helpful. Thanks in advance -- it's great to see high quality tools like your torches being made in the US. Keep the videos coming.
Thanks for your presentation! Kudos to you, your explanation of star patterns of gas flow is extremely helpful! I'm learning things now from your video that I'd hope that an apprentice metal worker might learn, so your video is extremely important to a whole bunch of people! (I'm a 70 y.o. retired pilot and amateur metal sculptor who recently changed from oxy acetylene to oxy propane.)
Thanks for the video. I just ordered a propane cutting torch just like the one you're using in the video and have never used propane to cut, so your video was perfect for me. Thanks for the info.
Great instructional video. Helped me understand how to use this specific setup. This guy should definitely be running a school when it comes to this kinda stop.
When this video first started out I thought I was going to hear about the Turbo Encabulator version of the OXY Propane Torch! I learned something new about the neutral flame that I did not know. After all I am an airplane driver not a welder. 🤣🛫
I was taught and always teach others to shut the fuel off first, then the oxygen. Also, there is no reason to fully open the valves. But there is a big reason NOT to open them fully. 1.5 turns is enough for fuel and oxygen to fully pressurize the system.
You ALWAYS, ALWAYS, Always turn the fuel off first otherwise as you turn off the fuel without the oxygen running, the flame of the fuel can crawl up the torch and gas hoses and cause an internal fire and possibly blow up the regulators. That's why the ministry requires flame arrestors on the base of the torch. When shutting down the torch the saying is " A before O or up you will go" referring to shutting off A (acetylene) before O (oxygen) or blow yourself up.
That is the way I learned it as well. Ag class at a small high school in S. Az in the 70's. My instructor was an island-hopping Marine in WW ll and a serious cat. He enforced lessons by a well-meaning smack to the back of the head, generally. Very effective I might add.
Thank you sir every thing you showed me I was doing wrong ,Trusting my welding supply to show me the correct way . I could never drop the cut piece like you showed ,I would have to tap off with a hammer . I had pressures at regulator set at what they suggested ,Witch was way to high . Thank you . My cut piece drops now just like yours .
This video is well above average compared with those who wish to deal in superfluous and useless chatter. Those who go to youtube for helpful information need more ladies and gentlemen of this caliber,
I started out watching this with the sound off and was getting a distinct Will Farrell vibe from this guy...so now I want to see Will Farrell do a skit about a welding teacher.
I have a question that may sound stupid. When should you stop using the oxygen from the cylinder? Is it a case of going until you lose all pressure or should you stop before that. I have flashback arrestors fitted if that makes a difference.
He did a fantastic job of presenting this propane torch, i didnt know propane could be as fast and clean as Acetylene in an cutting operation. Im still not convinced that it could be better for welding than Acetylene tho. Also this Gentleman could just be the dad of Jason from Fireball Tools.
People DON'T weld with Propane! Acetylene and sometimes Hydrogen, that's it! Brazing, silver-soldering commonly, but Acetylene does it all if you have it, if you can afford it, if it's not out of stock (!).... I use both. THIS VIDEO shows something that really nobody knows about using Propane and Oxygen, I try to get students to watch it, 12 years later.
awesome lecture! I'm going to buy a setup and only use propane. I figure the lower temp will reduce the chances of "flaying" charred steel attaching itself to my cornea. :)
Filling a couple acetylene tanks today, I realize I have to move to a cheaper gas and propane will seem free in comparison. Just a couple fills will pay for the new equipment.
Yes! He's getting those numbers from a table in the little book that comes with the regulator. In the welding world generally I think there's a lot of guessing at this point because the information is lost, or you are using different brands of torch and tips! There's general information about oxy-acetylene cutting that helps you figure this out (it's in old books), but oxy-propane technique is not so common.
are there more videos on this channel??? I only see 3 videos from 6 years ago! It asks me to subscribe and to turn on notifications for upcoming videos, but it seems like we'll be waiting awhile.....
Why did you shut off the oxygen to kill out the flame? I've always been told on acetylene rigs to shut off fuel first. Is this a difference between propane and acetylene?
I just boucht an oxy acet torch and I am needing it more for heating. SO do you know where you would get a conversion kit to get it from acet to propane? thanks
You can get propane tips, they look different. The acetylene tip just has a plain hole in the flat end of the tip, propane tips have a recess in the end, or some kind of extra holes, something to "anchor" the flame. Propane burns slower than acetylene, and if you use regular tips you can't really crank it up b/c the flame will blow off. You'll see a gap between the tip of the torch and the flame, and it will want to go out. Air propane tips have these sustainers on them, too. If you look at the tip there might be little holes around the central one, or something that looks like a gear. SO, your main working flame is surrounded by little flames that keep the main one lit.
Seems a big difference in the shutdown. I was accustomed to fuel maintaining combustion after the oxygen shutoff. Perhaps I was using an unsafe procedure or am less familiar with propane as fuel.
it really depends on what you're trying to do... for the most part, oxy-propane will get the job done, cutting, brazing, heating... plus it is readily available in case you run out... but you CANNOT weld with it, only with oxy-acetylene.
That's a load of bullshit, my 1910 Westinghouse vice jaws were repaired in 1998 with oxy propylene welding by my welding instructor. Still use the same vise today, and a pinch point bar and a simple jack all repaired via oxy propylene. Go find a new hobby.
@@tonyb7748 okay maybe you have some reading comprehension difficulty I said oxy-propane first of all Secondly, from what I read (and remember at this point..), it has to do with the stoichiometry of oxy-pro* combustion i.e. not balanced so you get inclusions of hydrogen (I believe it was hydrogen) molecules in your steel What do you know about metallurgy?
Open the bottle valves all the way, so that if anything bad happens, you have to stand next to the propane bottle for an entire 30 seconds turning it back off again
This guy is a throwback to the instructional movies from the 60's and 70's.
Lol yeah .... Not only his presentation but his voice too. 👍😁
It's like I'm listening to a radio announcer from the 80's. You got a beautiful voice.
10 years old, but still the BEST video giving the procedure for oxy/propane cutting.
Gotta love this presenter. He has such a great, classic baritone voice....he could do voiceovers for movies!
I keep wondering if this guy is an actor, or the best technical salesman ever, or a SMITH engineer or what? I don't meet people like this in the welding sector.
Perfect lesson and Smith makes beautiful torches.
I don't think I have enjoyed watching any youtube video as much as I have enjoyed this one. Such a proffessional. Thank you so much. There is so much to learn from this gentleman.
If Harvard had a shop class, this guy would be the Professor there.
I just wonder did how many people who went to Harvard took a shop class?
No, you idiot

Not too much info, and not too little.
Exceptional, clear, confident, precise and professional presentation. Thank you.
Super video, thanks. Never saw that “star pattern@ trick for regulating O2 ratio.
I think that that was the best presented and organised instructional video i have ever seen. Ever.
Sensational, thanks.
This was the best description I've heard in depth and I surely appreciate it thank you so much
Excellent instruction lesson Dale.
You’re a great teacher.
I learned how to use an oxygen acetylene cutting torch in school but never oxygen Propane. Great vid 👌🏾
An excellent instructional video by a professional. Covered everything I was curious about. Thank you Sir.
It would be great to see him make a video demonstrating proper adjustment of an oxy propane rosebud
Now THAT’S an Instructional video 👍👍👍👍👍👍👍👍👍👍
👍 TWO THUMBS UP 👍 This video should be a mandatory watch in all metal shops 💯

Can an acetylene regulator be used for propane?

very well done video, thanks. the instructor is very well spoken.
Simply just brillaint.... Thanks very much!!
Excellent video. Wasn't aware propane could be used to cut steel. Thanks for posting it.

Throw and precise information. He explains things very well. All-around excellent video!
My left ear enjoyed this
sir it was a great presentation
Handy to know. Got to book a course to use burning gear
thank i can finally cut thick plate properly
Great info.
1:30 - Back fire connectors between hoses... and.... torch - Check.
But really great video. Thank you buddy
I have a question that may sound stupid. When should you stop using the oxygen from the cylinder? Is it a case of going until you lose all pressure or should you stop before that. I have flashback arrestors fitted if that makes a difference.
man that torch is clean and shiny lol
One of the best instructional videos I ever seen . Lot of trash videos on TH-cam this vid is like a oasis.
The red propane cylinder used is such a better size for a cart than a 20 lb. grill tank. What is the size or name of the propane cylinder?
He did a fantastic job of presenting this propane torch, i didnt know propane could be as fast and clean as Acetylene in an cutting operation.
Im still not convinced that it could be better for welding than Acetylene tho.

close oxygen first
cool story bro

what is the approximate burning temperature of this mixture and is it better than mapp and oxygen??
Seems a big difference in the shutdown. I was accustomed to fuel maintaining combustion after the oxygen shutoff. Perhaps I was using an unsafe procedure or am less familiar with propane as fuel.
2.5 inch radius or diameter of star?
