GOOGLE: Why is acetylene cylinder filled with porous materials? Acetylene gas is mixed in liquid acetone for safe storage and usage. Acetone in acetylene cylinders helps stabilize the gas making it non-reactive within the cylinder. ... The cylinder is then filled with porous material like firebrick. This keeps the acetylene in liquid form making it easier to transport the cylinders.

@@fraterjr it holds porous material due to its volatility but if your bottle has been on its side for over 2 hours then as Austin stated it much stand up for ATLEAST 45 minutes to help the acetone settle. Acetylene is a volatile gas and Oxygen is an excellerant

@@WardWeldz You’re spot on regarding acetylene. Remember oxygen is an oxidizer. In the video Austin says it is flammable, technically this is incorrect but the reaction to an existing fire when an oxidizer is added is such that well your term, accelerant, paints the perfect picture. Oxidizers can be a little peculiar and are given their own classification pertaining to their storage, transportation, use but to keep things simple they could be thought of and should be treated as if they’re flammables.

What gloves are you wearing in this video Austin?

gravity keeps the acetone near the bottom of the tank. If the tank is used on the side you will burn off acetone and the pressure of the acetylene tank will rise beyond the normal tank pressure!

You're getting into the wrong profession if you don't want to hear profanity...

​@bigrichard660 if you aren't aggravated, as in you just got burned, there's no reason for profanity.

All bottle are to be opened all the way open. The design of the packing are made to operate all the way open or closed Bottles are to be f acing up when transported or used as per OSHA.

Pleasure is all mine!

I'd like to hear from you why you didn't know? I've encountered so many people who seem never to have had formal training, and expected me to put up with them being a hazard to me, others, themselves, and the building... Acetylene on its side, no flashback arrestors, acetylene pressure far too high (unnecessarily high) over 14psi, a pressure beyond which acetylene can become unstable, decompose, They don't have a plan to deal with a cylinder that's been overheated, they don't realise that acetylene and copper or silver can form explosive compounds... copper / silver acetylide, that fixed oxygen pipes, though you can fabricate them from copper, you'd best not use silver solder, and you'd best double degrease them before use... (oil + oxygen = bad) and so on. And then, when they cut, the cut's RAF (rough as...) so needs a lot of grinding time... With my track cutter, I could cut within, perhaps 10 thou of size, and just flick the sanding disc over for a satisfactory finish, no wasted time. Other guys? their cutting was truly awful. Right nozzle, right pressures, right flame character, right flame relationship to plate, right speed... Nice job... Some guys see O/A as a demolition tool... They're wrong...

@@robertlawson8572 You guessed it in the first five seconds. No formal training. I was taught by my Dad, who will tell you that he has had no formal training. You either learn by going to school or experience. And KZfaq of course.

@@bigchuckyinkentucky6267 Thanks for your honest reply. I had a long reply largely drafted, but it disappeared... So, a short one must do... In military service, I asked a fellow corporal in a different trade (he was a joiner) what his medal was for... The story he told was fascinating. Serving in Singapore, a junior rank came to him (the nearest NCO to where the junior was working) in a panic, having realised his acetylene cylinder was heating up... (the contents were decomposing) for whatever reason. The Joiner had no idea what to do, the junior rank knew, but was afraid. The corporal performed all he actions the junior rank told him were necessary. Shut the plant down, remove the regulators, discard the Oxy cylinder to minimise weight, get the acetylene cylinder on its trolley, into the open, ideally 200 yards from any buildings, open the acetylene spindle valve to let the gas escape to atmosphere and either spray with water or immerse the cylinder in water. Never use a jet of water, you may topple the cylinder, it may roll in a direction you'd prefer it not to..., and, horizontal, with an open valve, the acetone in which the acetylene's dissolved, escapes... Anyway, the Joiner saved the day, and was decorated for it... I told him that, since my early teens, I'd viewed welding plant with respect, because, when a local car repair garage had a fire, (in the mid 60s) the explosion of the acetylene cylinder had been spectacularly noisy, and caused considerable damage to the building. And when I trained in the use of O/A I understood better what I was dealing with... A potential bomb... I said I thought he was brave, and deserved the medal (Queen's Commendation) He said he'd just have evacuated the area, had he known the possible results... Modest?

The only problem with laying the tank on its side is you get liquid fuel instead of gas! You won’t blow up or catch fire you’ll just get a big flame that won’t cut!

BEGINNERS MAY NOT FLOW ACETYLENE ENOUGH! TOO LITTLE ACETLYENE GIVES REPEATED SNAPS! POPS, CRACKLES. CLOSE THE FUEL, THEN O2 AND BEGIN AGAIN. FLOOR MAT ALUMINUM CASTERS.....SOOT 100% THEIR DIES AND ALSO BITD GM TORNADO STEEL STEERING CASTINGS DIES WERE WATER COOLED, AND SOOTED BEFORE FILLING WITH 2800*F STEEL.

Im a professional structural inspector, nice to meet y’all.

@@alexandrorodriguez9453Im a professional structural welding engineer it's even nicer to meet y'all.

@Deryk Lilley The valve on a oxygen tank is double seated.

My college instructor also said to backseat the oxy tank Valve. However, as a diesel mechanic, most of my torch work is small or quick jobs and loss from a small leak is negligible if any, i usually open it about a full turn and i get all the oxy my torch will use.

all you people arguing over whether O bottles are double-seated: you can look it up. It's an industry standard. There are no variations from this standard in the USA. GO LOOK IT UP. LEARN HOW TO SEARCH THE WEB. STOP SPREADING MISINFORMATION.

@@railgap I’m not arguing, I’m saying what I was taught

@Deryk Lilley I’m in welding school and you open the oxygen and acetylene cylinders all the way

h0ó😊😮😮😮😢

Your dad sounds dangerous. Prolly fun guy

Maybe chemistry works differently across the Atlantic? Set your O&A pressures to the torch manufacturer's recommendations. Light the acetylene, set the acetylene flow to render the flame soot free. Adjust the oxygen to get a neutral flame for cutting. Check that when you apply the cutting oxygen, that doesn't radically change your flame's characteristics. When your nozzle heats up in use, you may have to correct your flame adjustment... If you're lucky, doing bench work, and have the torch connected via a gas economiser, you won't be obliged to adjust your flame characterisics every time you light up, but you must keep an eye on them... My instructor, 50+ years ago, when flashback arrestors were neither obligatory, nor necessarily as good as today's versions, dashed up to me when my torch (I'd contaminated the nozzle) was backfiring like a machine gun, and told me "clean that nozzle, and start again" and "If it happens again, as a safety measure, try and catch me..." Only half joking, I think...

I’m 72 and still learning, when I taught basic welding to adults my oldest student was 80.

You bet! Thank you for watching!

I still don't know that it is. Should sound smoother than that. And 10 psi seems very high for a single aught. Good basics video though overall...

You bet! Thanks for watching!

Welcome to the trade. I just retired after 45 years. I spent the last 30 repairing rolloff boxes for the trash industry. Never ran out of work.

As a fitter i can honestly say good welders fit their own pipe. Fitters design measure draw everything but a good welder knows what they want for gaps and also how to handle the draws and how to roll flanges way better than any basic fitter can

It’s called a double seated valve

@@Kevin-is-here that's what I was also taught and it should be all the way open for safety. Maybe different models exist that can handle the O2 pressure safely now. Idk

Back seat valve

Thank you for showing your support! And for the kind words!

You bet! Thank you for the sub! And for watching!

By now, assuming you passed / won, and I hope you did, you'll have discovered that we generally use a guide (maybe a piece of angle iron) for straight lines, and a trammel of some sort for circles. freehand cutting (while admitting it's necessary for pipe prep) is a torture reserved for college... One of my college test pieces was completed while shaking my right foot around trying to get some hot slag down into the toe away from flesh...

Are you talking about back seated?

SCUBA DIVER, AIR STATION/COMPRESSERS, CASCADES. BACK SEAT THE O2! SNUG! BY BACK SEATING THE HIGH PRESSURE VALVE STEM IS RE-SEALED THE SAME AS IT IS WHEN THE HP SEAT IS WHEN IT IS OFF. MOST H/P VALVES ARE REBUILDABLE! FULL ON 02 AND SNUGGED OPEN.

You bet! Thank you for watching it!

Man that sucks about your truck! I have a cousin that used to run a rig welder while building his own business to the incredible fabrication and welding shop that it is now. One story I remember was one day he had to drive his welding rig to the DFW metroplex to take care of some business where he would have to leave his truck out of site for about an hour. As he approached the parking lot he noticed a beggar on a corner. He offered a deal with this beggar, paid him 20 bucks on the spot and said if you’ll watch my truck and when I get back nothing is missing and you’re still here I’ll pay you another 20. Worked out well for both of them, I believe similar out of the box thinking is what has aided in his success.
