Tips never wear out, they only grow up to be the next larger size tip.

Couple of things not mentioned. First, when you purchase oxyacetylene hose, make sure you get oxyacetylene hose. There is another grade/type which looks identical but is meant for propane or map gas only. If you use it for oxyacetylene it will degrade from the inside out and start to leak through tiny pin holes on the fuel gas hose. This is because the acetone vapours carried with the acetylene will attack and slowly dissolve the hose itself from the inside where you cannot see the damage. Second, the reason for using a striker to light a torch instead of a match or lighter is in effect gas conservation and safety. The cup that you always have on your striker is actually a small gas reservoir that collects some additional gas and makes your torch light easier and quicker. If you use a match or a lighter it can be difficult to light a torch where there is significant air movement from fans or, if working outside, wind that blows the gas away. In addition, using a striker ensures that you hand is away from the flame ignition point and you are less likely to get burned. Third, the charts that your torch manufacturer provides for pressure settings are only good for about 25 feet of hose and are only guidelines. If you have more hose, the pressures must be increased to compensate for friction within the hose dropping the volume at the torch tip. A better way to set your gas pressures is as follows: 1. With the acetylene regulator adjustment screw fully relaxed crack the main valve on your acetylene bottle and when the regulator is fully pressurized open one full turn. Adjust your acetylene regulator so that you just have a small amount of gas flow. 2. Light your torch and open up the fuel gas valve on it all the way. 3. Slowly increase the pressure from your regulator using the adjusting screw until the flame just blows away from the tip. This is the maximum amount of gas that particular tip will flow. NEVER EVER set your acetylene regulator for more than 15 PSI! Acetylene can become unstable at higher pressures and become self explosive. 4. Close the torch fuel gas valve until the flame returns to the torch tip or shut it off completely. 5. Ensure the adjusting screw on your oxygen regulator is completely relaxed, stand to one side or out of the line of fire and crack the valve on the oxygen cylinder open and allow the high pressure to ease up to full pressure. NEVER OPEN THE VALVE ALL THE WAY UNTIL THE HIGH PRESSURE SIDE OF THE REGULATOR HAS BEEN SLOWLY BROUGHT UP. If you open the valve wide initially you can damage your oxygen regulator's Bourdon tube inside of the pressure gauge and in extreme cases actually blow the glass out of the gauge itself. The surge of high pressure has also been known to blow the regulator body off the bottle when the regulator has been damaged hence the standing to one side out of the line of fire unless you really want to catch a pound of regulator propelled by 2000 PSI with a portion of your body which can be painful if not deadly. 6. After the regulator has been fully pressurized, open the oxygen valve all the way and adjust the regulator pressure screw so that there is a small amount of oxygen flow. 7. With the torch lit and burning at the tip (not blown off the tip), open the oxygen valve on your torch all the way. You will notice that the flame changes when the oxygen reaches the flame. 8. Adjust your oxygen regulator up until the flame becomes neutral. 9. Increase the opening of your fuel gas at the torch slightly and bring the oxygen up again until you have a neutral flame. Continue to open the valves as described and adjust your oxygen until both torch valves are open fully and you have a neutral flame. Your torch is now set for the maximum flow that that particular tip will flow and is at it's highest efficiency. Fourth, when using fittings or hose splices on oxyacetylene systems, the fittings cannot be copper. They must always be brass. Copper and acetylene have an affinity for one another and combine to form a new gas which is unstable and self explosive at virtually any pressure! In England, they used to use acetylene for lighting in homes. The gas was run through copper piping and on occasion entire blocks of homes and their occupants would simply blow up for no reason until this was discovered. Oops........so sorry, my bad. Fifth, never discharge an acetylene bottle at more than 1/8 of its contents per hour. Higher discharge rates can result in the acetone in the bottle being drawn out into your hose and torch. If you must use higher rates consider using two bottles with regulators and manifolding them together. Sixth, when cutting material cant your torch tip slightly so the flame is going in the direction of the travel. This will preheat your material and give you a cleaner cut with less slag adherence on the bottom. Thinner materials will require more angle than thick. If your cut is so poor that the pieces stick together use a hammer to part them and not your torch. Nothing speaks of poor practice more than a torch that has been used to hammer pieces apart! I know that some are going to give me flack over this but consider this: I am a journeyman welder with over forty years experience and I have never blown a gauge up or destroyed a torch. A torch can be a versatile and precise tool in the hands of a good tradesman but, like anything else, it can be so much junk when abused.

I found this to learn about oxy acetylene torches, stayed for the dark humor and learned a whole bunch of things. Well done!

With all due respect to my high school chemistry teacher, I just learned more chemistry in the first 8 minutes of this video than I did in my entire high school chemistry class. Thanks!

I have been using my avetylene bottle completely upside down hanging from the ceiling for 30 years and nothing bad ever happened.

I came for the dad jokes. I stayed for the dad jokes.

Two things to add: I've used oxy acetylene for about 35 years. I was taught and still use the practice of aligning the tip and main valve knobs up like gun sights. This keeps them out if the way, keeping a jacket sleeve from "adjusting" the flame. It also puts them in a convenient, consistent location. Try it. You will fall in love with it. Also, I would stress the importance of opening the acetylene tank valve no more than 1/4 turn. I was taught this, and knew it was so the valve could be shut quickly. This was driven home for me one night when a spark caught a small leak in the regulator assembly. I heard a pop, looked over to see a little jet of flame onte regulator, and nearly dropped a stinky twinkie on the spot. I was able to avert big trouble instantly with a quarter-turn. My rig got a very thorough inspection before I fired it up again. Great video, and thanks for promoting safety!!!

That's incredibly dangerous. In my shop we store the tanks in the oven to keep them out of the way...

Given that the way rusting was explained to me in high school chemistry - as "very very very slow burning" - you've brought us full-circle here. Well done!

I was having a shitty day until the Sesame St. "Nuh, Oh, Ch... Notch!" part came on. I have tears of joy rolling down my face. Your humorous editing bits are so great. Thank you for brightening my day!!

"Just like my boy, its chained nice and solid to the wall" Totally caught me off guard! LOL! 1:45

To those who hang their acetylene bottles upside down, who cut or drill holes into the bottle, who mix the acetylene and oxygen in one tank, and who abuse or don't use the regulator or valves, you have missed the most effective way of using an acetylene bottle. That way involves turning the filled bottle inside out. It's a lot of work, but the results are impressive.

thank you for saying burninating. you're doing a fine jorb tony.

Glad you brought up the subject of lighting the torch. Since we aren't always going to be standing next to the person lighting their new torch for the first time, or the kid that uses your shop while you are off doing something else, we can't slap them upside the head before they burn down the shop. 1. My reason for using the striker to light the torch is, I was taught to plan for the worst. A stoichiometric flame oxy-acetylene flame has a huge amount of available energy. Mr. Stankey demonstrated it by filling a small balloon with acetylene, setting it on the welding table, and igniting it. It popped. No big deal. He then filled the same size balloon with oxygen and ignited it. It just deflated. Then he llt a flame on the torch and turned off the acetylene at the tank. If you are crazy enough to do this leaving the oxygen on lets the flame go out without flashing back into the torch. When the flame went out he turned the acetylene tank back on and filled another balloon the same size with the stoichiometric mix. When he ignited it the explosion blew two firebricks out of the top of the table. Most of us old guys quit smoking after the first heart attack, but for you young guys who still think carrying a lighter is cool, think about where your hand is when you are lighting the torch. That extra distance the striker gives you is handy for when you are learning and keep having to relight the torch. Yup you won't always turn off both valves and let the torch empty before restriking it. That's when you figure out it makes a nice big bang even without the balloon. I know at least one idiot will spend a few hours making big bangs after reading this. That's okay. Just do it out in the middle of a cornfield some where. You will only blow down a few rows of corn and the coyotes will clean up the mess. 2. The striker has a nice loop in the handle. When you are an iron cutter you can hang the striker on a short chain and clip it to your belt. That way you don't need to take off your glove, dig into your pocket, light the torch, stuff the lighter back into your pocket, put your glove back on, and go to work. That's especially nice when you are working off a ladder or on a catwalk 30 feet up. Climbing down to get your glove, lighter, or the stuff in your pocket that came out with the lighter gives your firewatcher a great story to tell about you for the next 40 years. Note: Yes you do need a firewatcher. Those sparks will set off pretty much any flammable materials they come in contact with including your pant leg. Side note: Don't wear pants with cuffs, or roll up your pant leg. I know that Johnny Dep does it. Look him up. I don't have time to explain everything. With the goggles on you won't see the flame. You will find out when the fire is up past your sock. Again, not cool when you are on a ladder. The firewatcher should let you know in time to keep your short and curlies intact. Thanks for reminding me of old times Tony.

I just watched a video on something I already knew. . . But what I did learn is where candy corn comes from. Thanks uncle Tony.

It's amazing. I'm researching what it takes to weld with oxyacetylene, and after sifting through all kinds of videos I find your video and all just makes sense now. Thank you!

The reason for not using a lighter? a striker doesn't blow up in your face when molten metal hits it

I had no idea there was candy corn inside O2 cylinders! The more you know.

This is probably the best instructional video about any subject I've ever seen. In less than 20 minutes, you've covered the basic chemistry in a simple way, and a huge load of important but basic things, and many good tips, all in an easy-going and entertaining style. I'm not usually the person that throws praise left and right, even when it's deserved, but this video... is a PERFECT example of an excellent educational video. Many thanks!

Honestly, one of the more useful welding videos I’ve seen. Very useful info and explained in a father-to-son sort of way. Thanks again...dad.

God I love this channel. Hilarious commentary, crisp videos with nice editing and great projects. Keep up the good work.

"Just like my boy, it's chained nice and securely to the wall" You're too much this old tony. Nobody ever really taught me oxy-acetaline, so I appreciate the tips. How long should the flame be? Should I use more oxygen, or less acetylene? I wouldn't mind a part 2.

5:08 the word "Sharpie" on the pen turns into the word "Subscribe" love it man, I do the same thing in my videos. Easter eggs are the best eggs.

7 years ago?! I remember watching this in the past.... but I didn't think it had been that long ago. Love your content, TOT! Thanks again!

This man should have a TV show.

Dear Tony, your work is exceptional, the combination of relaxed laconic humor, excellent presentation and production values makes your work stand out of the "rest" As always Tony, your work is a genuine bright spot in the KZfaq pantheon. Cheers David

I'm just getting into welding, been reading and watching everything I can find. Loved that shot from the camera behind welding glass. Being able to see the puddle while you add metal was very cool

Man I miss oxy welding from high school. Nothing more fun then watching your class mates pop the bubble from too much heat and light themselves on fire. 😊

Hi Tony, This is Old Bob. The time I started to weld we had no acetylene bottles. We used carbid, the white rock-like pieces and let water onto them. The gas which generated collected in a water filled tank which had a rising dome for the gas which came through the water. if we wanted higher pressure we put more weight on top of the dome. To change the "carbid" (English?)it was a horrible job. There were 2 drawers with air-tight locks, they had to be opened and pull the tray of used carbid? pulp out, clean it and re-loaded. The smell was beyond bearable. If you know more about that, please let us know, I do not remember more, it was over 75 years ago.

“Chained to the wall just like my son” that got dark quickly

Old Tony , I'm thinking old as , "OLD" ! My start at Welding , was High School Shop Class , 1956-1960 , Detroit Public Schools , Cody High ! The " START " was Oxy-Acetylene , welding " period " ! You learned to TORCH Weld , or DIDN'T go on from there !! Still today , I feel , to become a " Real Welder " Oxy-Acetylene , MASTERY , is a MUST !!!

You have to stand up your acetylene bottle for double the time it was on its side is the general rule we learned in Sno Isle Skills Center in Washington State. It’s important if you don’t know how long it was on its side then you leave it upright for 24 hours. Good luck! God Bless! Safety is NOT an accident! 🖖🏼❤️🇺🇸

But AvE said to learn with a Stick! What do I do? Never mind. Problem solved: Living in an apartment means I just watch all the videos about welding so I already know everything. I'll just comment on videos telling people how I once did it better with a frayed extension cord, a pencil lead and cutoffs from a sheet metal shear.

"I know because i've weighed them" I nearly spat coffee all over my laptop

Oxy-acetylene yep reminds me of the time I was in agricultural mechanics back in high school they kick the guy out of class permanently cuz I caught him trying to weld to the acetylene tank yes that's right he was trying to weld a strip of metal for practice to the acetylene tank

I have watched a bunch of MIG, TIG, and now Oxy acetylene KZfaq videos and you taught me more in this video about how and why it works than all other videos combined!

Good one! I remember brazing course during apprenticeship..we quickly realized that the torch could set pretty much anything on fire :D :D :D

*You get the mix of education/entertainment just right!.....80/20*

You have provided more insight in this video about the matter than all the info I could gather around during years of asking in shops and welding stores. I re-watch it every time i have to use my oxy-acetylene equipment. Internet is awesome because of people like you!

Heck, your humor alone made me a subscriber. But as a newbie to welding and fabrication, your instruction and information are definite bonuses. 😁

Props on crediting Jody, who hasn't learnt something from Jody at some point. The man has changed welding on a global scale, honestly.

My dad worked as an engineer at a large valve works. One day a worker was changing a MIG gas cylinder and the full bottle tipped over sheared the valve off took off like a rocket across the shop and went through 3 brick walls before running into a concrete pillar and dumping out the rest of the gas! Chain your bottles!

I don’t know how many times I’ve watch this video, it’s been a lot, entertaining every time.

You sir are a natural, thank you for such an awesome video. Like most "diy" sorts I just bought home a complete set up with no idea what I was doing, and thanks to you my house is still standing, the burns are minimal but I may never see the cat again.

Tony, your channel is becoming one of my favourite on KZfaq, your humour is amazing!

You know, when I see you post a new video, I always look first at how long it is, and my joy is directly proportional to it's lenght. ^^ Watch time!

the first thing I heard was the exact same muffin man song I jammed to while on a glorious acid trip and it already made this video glorious. Thank you

Tony, so glad to hear you say it. I have always thought brazing was the best way to learn welding. You can see and understand what is happening and it happens slowly.

Great video!! In Argentina, the tank that we use for acetylene has a small deposit in the bottom to put Calcium Carbide. Then you have to add water to that deposit and close safely. This mix deposit generates acetylene. You have to renew this mix periodically to generate more acetylene.

Stoichiometry, LMAO!! Seriously Tony, one of the absolutely best gas welding introductions I have ever seen. I totally agree with learning with gas gives you a huge jump on MIG and TIG. Love the special effects, especially the candy corn and the terminator bit. Keep up the good work. Thanks again- Fred

Oxygen and Acetylene is actually what my school uses in our welding class. My favorite type of welding!

I wonder how many people realize how skilled Tony is. He's super humble about it but dude is brilliant and very skilled

Thanks Tony, I really appreciate your videos. For me it was a good refresher after not touching a torch for decades. But you did not mention the safety point I was taught. When done, flush the lines and turn off the bottles. Sequence: you turn off both taps on the handle then close the O bottle then open the O on the handle and blow out the O line. Then you close the O at the handle. The close A, at bottle, open the A on the handle and flush out any remaining O in the torch, then close A at handle. This ensures no explosive mixture in the handle and it takes the pressure of them regulators and hoses.

I have learned much from watching your videos, and at this point you are my second favorite Tony on youtube.

"there's a ton of videos on welding. I know that because I've weighed them!”. Not only are you incredibly knowledgeable, but you're funny as hell! I love your videos.

O2 tank full of candy corn? I approve. Excellent hiding spot.

One of the reasons you shouldn't use a lighter to start a torch is distance from the flame. The first reason is your hands proximity to the flame with a lighter while the second of most lighters are plastic and nothing says fun like a butane fireball to get rid of all that annoying hair on your head, arms, and the eyeball dust collectors.

Well done! Very clear information, not to scientific, but not just the nitty-gritty. Good tutorial on setting the flame properly. Thanks for making another great video!

Loved the formula, very educational and answers the question "WHY" when it comes to pressure. Would like seeing more in future vids of flames/pressures while looking through glasses/shields and when to use oxygen rich vs carbon flames.

Hell yeah a 5 year old video that I wasn't searching for but was unusually useful. Thanks buddy

Thank you for a VERY informative video. Great humor, too. I loved the joke "I know 'cause I've weighed them."

That was great! I did a welding course a few years ago, and I learned more about oxy/acetylene in 18 minutes here than I did in that ten week course - thanks!

I really like your channel. Perfect balance of learning and information, and just enough schtick to be funny without being juvenile and annoying. Really great stuff man. Bravo 🙂

Tony, just want you to know how much I appreciate your educational and informative videos. Haven't had any Ox-Ac instruction since first yr of engineering school - over 50 yrs ago!! "Flame Arrestors" - something new within the last 50 yrs? Never heard anything about 'em. Thanks for hitting "the high points" which has removed fear from me lighting up my system. Will check out my hoses first :)

What an incredibly informative and entertaining video! I learnt so much! Thankyou!! 😊

If your day job isn't involved in teaching it's a shame.

9:50 My metal working teacher gave good reason for that "lighter is a no go" thing. He said that there's been accidents when people have had faulty tip in their sets, banged nozzle accidentally and didn't notice. Then when igniting they've found out the hard way that faulty nozzle can direct flame on very odd angles and well with oxyace, the heat is so great that you'd get really nasty burns even with small gas flow amounts.

Thanks for making the video. I just bought my first oxyacetylene setup and I was a bit nervous to use it until I saw this video. Very good information!

Flash arresters do not require heat for operation. The blast wave of flash back provides pressure to unseat a pin shaped valve held open by a spring or gas flow from tank.

Why is your oxygen bottle filled with candy corn? 4:00

Excellent presentation. Nothing I didn’t know, but presented so well that I watched the whole thing anyway. Very engaging! Great work!

Watched this a while back, probably years ago, and came back to it. Still great. That's the mark of excellence.

1:44 “Just like my boy, it’s chained nice and solid to the wall” Sure as hell caught me off guard

I was 16 in 1967 and I had a job on a building site in the UK. I was in a small team whose job was to bolt heavy hot-dip galvanised plates to threaded studs set in concrete. None of the threaded bolts were set with any accuracy, so we had the job of re-cutting the bolt holes. We used oxygen-acetylene to make the holes bigger, but the hot dip galv really got in the way and made our job that more tricky. I was only 16, health and safety was non-existent, but the team leader let me cut the holes. It was so much fun handling a very dangerous but very powerful tool at 16.

Thanks Tony I didn't take this stuff in high school nor have I had any college courses on welding and cutting. I've been wanting an Oxy/Acetaline rig for years. Been using a borrowed rig for a couple of jobs in my shop and I have used the set up in a couple other shops years ago but my knowledge base is very minimal. I'll be watching this again... a few more times before I actually get my own rig. Thanks again. Love your method of teaching too. Keep up the great work.

I have been welding and soldering for years and I have not yet explored the Oxy-Acetelene setups yet. There have been many instances where this setup would have been very useful. Thank you for the informative video. Looking forward to trying my hand at this.

i'm a glassworker, and in school we were taught to light the torch with something that didn't put your hand close to the torch, in case you've somehow bumped the O2, or had a large outer fire on by accident.. it's possible you could splash your hand with a whole lot of flame if it's right there. lots of people use zippos, because the flame is so long. i use a regular bic, because i'm stupid.

nice educational video ! I Just like your stile... But you missed out on a lot of stuff: 1.: To clean the nozzle you shouldnt use the needles as they wear out the nozzles. Its better to rub the tip of the lighted burner on a piece of scrapwood. This extinguishes the torch while the glowing charcoal relights it causing it to pop. These mini explosions will blow out the dirt without hurting the nozzle. I Learned it that way (Professional mechanic in Germany), works fine. 2.: Your oxygen pressure is waaay too low. Use at least 30PSI to get safe operation and full capacity. This is due to torch design, in the bottom part of your nozzle (The part that sticks into the handle) is a jet pump powered with oxygen to suck in the acetylene. This is necessary for good mixing and to allow keeping the acetylene pressure low while using lots of it. 3.: Never increase the acetylene pressure above 7 PSI as acetylene is not stable under pressure. The high bottle pressure is only possible due to the "solving in acetone trick", if attemptet outside the bottle the acetylene could decompose generating massive heat. This decomposition can also be caused by local overheating of the bottle. The bottle will then start to heat up itself wich makes an explosion nearly unavoidable. Its kind of a fire without the need of a second component... If you ever notice an acetylene cylinder getting hot by itself- just run as far as you can and call the fire department! 4.: Never use pure copper with acetylene (only the tip of the torch is excluded...) as the copper will react with the acetylene, forming a highly unstable compound wich will explode on shock and contact. 5.: the proper way to light a torch is to turn on the oxygen a little bit, then turning on the acytelene and then lighting the torch. That was you get no sooty mess and the jetpump- design prvents any backfire during startup. 6.: Lighting the torch with a gas flame is perfectly fine, we had welding stations that had a small acetylene flame attacht to a dual valve device. To start welding you just pick up the torch an hold it close to that flame an the torch ignites perfectly set. to stop you hung it back wich closed both oxy and acetylene. I would not recommend to use a lighter because sometime you get a nice fireball during ignition. Especially if you are not well enough trained at thas and you miss the perfect gas mix for a while. But if you are wearing gloves and do it a lot it works fine. Sorry, got a lot of text... ;-)

Brilliant video. This took me back 30 odd years to my apprenticeship. Everything I was taught about gas cutting and welding is in this vid. And more. Turning the gas off and still cutting I'd never seen or heard of! So when he asks "did you learn something?" I'm nodding away.

Highest Respects, learned quite a bit to save my life / and honor in this under 20 minute video. Good quick start guide without all the unnecessary fluff.

after stick welding, gas welding felt like therapy since it's so quiet and gentle in comparison.

Tony, these videos just get better and better!

Mate, I would just like to give you a massive thank-you. Me and my partner have given up watching crap on Netflix and now sit down and watch your videos instead. It's getting her much more excited about learning to TIG, and using my lathe and old mill to make things so we're spending a heap more quality time together. Your videos are really well thought out, entertaining and exceptionally well edited. If you're ever in Australia, hit me up for a visit to the workshop and free accommodation and beers in Bathurst or Bangalow.

That was probably the best, informative video I have seen. That cutting torch was fierce! Trying to see how I can get into aluminium welding. Have only 120 in the house, and no breakers left. I hear tig/argon is the way to go.

The acetylene doesn’t have a smell, so they add sulfur so u can smell if there is a leak somewhere, it’s a safety precaution

I've been cutting/welding on and off (more off) for over 50 years, but it's still handy to brush up with advice from others. Good video, old chum.

I’m a glassblower and you just explained to me flame chemistry!!! Thank you

Wish my old shop teacher had gotten into this detail which would have saved a lot of time and this video burned my lunch..RIP

NICELY done video Tony; Some info for nerdy shop rats like me (with several grad degrees), not boasting but I often wonder how the hell I ended up as a machinist. Any who, acetylene is a very interesting molecule, discovered in 1836 by Sir Edmund Davy, does not hold the title of Sir, but I though sounded much better. During one of his experiments with potassium carbide (who knows what he was after) but he produced carbonized H AKA acetylene. In 1859 Marcel Morren (crikey must have a hard time in school, Oh look its Marcel Moron.) With my limited intelligence, dyslexia, OCD, depression, let us stop there; I do not know why but he was doing an experiment in which god knows why he was striking an arc between 2 carbon electrodes in a H atmosphere. Well he lived to produce acetylene after the ensuing violent Rx the carbon atoms torn loose bonded with H and produced a gas we all now call acetylene. Late in the 18th century H2N2 was being produced by reacting calcium chloride with water (Miners Light same Rx.) Now something north of 50% is produced from natural gas, ~13% from cracking of dinosaur squeezings and the remainder Ca chloride method. 350,000,000 pound annually (160,000,000 Kg for the metric crowd) As Tony mentioned storage is very interesting. A wee bit of diatomaceous earth, a nip of acetone into the tank at 300 PSI makes it much more stable. Two safety items I was taught never to set the H2N2 reg above 10 PSI, at risk of having the H2N2 change phase (liquefy and become very reactive. Number B never apply any grease to tank fittings especially O2, for thee obvious reasons. hydrocarbon + O2 (oxidizer)= boom. Oh BTW a pure carbonizing flame is used to place a coat soot on the inner portion of the "mold" when pouring a babbitt bearing just FYI. WAKE UP I am finished, just wanted add a little history for us nerds. Nice and informative vid Tony Thanks man, Doug

Man this brought back memories. That plop sound when acetylene start burning and it wonderfull full flame. The rainy muddy raw days when I was shivering with cold, this thing always helped.

My coworker had just clean some paint brushes with paint thinner. He pulled out the torch set at work to do some cutting. I still have the visual picture in my mind of him swatting out the burning rags on the workbench after he realized they were on fire!

Another excellent video Tony and congratulations on your meteoric subscription rate! ATB, Robin

Aw, man. I wish I had seen this back when I was working on my A&P license. It would have helped my welding project go a bit smoother.

I don't know why this is in my recommended but this was very informative. It feels like something the "cool" shop teacher would show to the class.

Thanks for the video. I am a student who is currently studying "Heavy Mechanic" and currently we are learning about welding. This video helped me understand and good tips.

5:46 i literally went "NO!!! THATS NOT RIGHT!!!" then started to balance the equation.... and then you did it for me... and THANK GOD for that i was about to spend 20 mins remembering high school chemistry.....

AvE : welding This Old Tony : welding what a coincidence ! :joke:

This old Tony, I miss your videos so much I’ve been rewatching your old ones. Hopefully life lets you get back into it someday. I hope things are going well for you.

Another great video! Learned something and I'm no rookie to a torch. Thank you

you made balancing chemical reactions WAY easier to understand than my eighth grade science teacher. Just for reference, that teacher is one of the best teachers at THE best private grade school in the US
