I know I have done it when I was a youngster, I had a flair that I wanted to put out and l pushed hard on the concrete floor in my dad's garage and it exploded, it was a very violent explosion, not good!!!
acetylene burns hotter but propane kicks out more BTUs per pound. I cut with a plasma cutter so I will be using a gas cutter to heat and bend. So I'm going with propane cuz I already have a 100 pound propane tank and propane is cheaper.
He's at least 6 feet away from the gas tank and the clipboard warriors whining about cutting too close to the truck obviously haven't had to cut the leaf springs off their truck before.
Oxy propane is the shiznit. Much cheaper and cuts everything you need. I have oxy/propane tips that will cut from 1/4” all the way up to 6” and I’ll never be cutting anything over an inch or so. But I got them just in case. Oxygen and propane is dirt cheap and you don’t have to worry about the 1/7 rule like you do with acetylene.
Good video other than the bad cut and I don't recommend cutting galvanized, idk what the pipe was but judging by the yellow/white oxides, thats burnt zinc. I appreciate the information though!
Natural Gas or Propylene is the way to go. Natural Gas is available almost everywhere and burns almost the same as Propylene. (Don’t go trying to plug into the house manifold). That’s my disclaimer 🤓 I can show you how to use a Natural Gas / Propylene torch in a way that would pin your ears back! Seriously from a guy who has welded for 29 years think SAFETY!!! If it’s not clean metal use a respirator. That pipe has been coated, the fumes will make your nuts shrink up and fall off. Second. Move the Truck! All it takes is a spark to get into a wire harness or anything flammable and you’ll have a serious problem on your hands. Keep posting videos.
@@Jordan-rb28 whats the cigarette going to do? youre actively trying to light the tiny little stream of gas thats pointed away from you... i imagine you could crank the valves wide open and spray it in your face with the cigarette lit and you wouldnt be able to light it.. i just spent 20 minutes struggling to propane to even light on a acetylene tip have to flick a lighter infront of it 10 times with just the perfect amount of propane coming out and at just the right distance from the tip if the flow was ever so slightly too high or i didnt have the lighter at the right point it wouldnt light.. this stuff does not want to burn or explode we have to get it in ideal circumstances for it to light up
@@AndrewBrowner because it's needless when a simple magnesium lighter is far safer and costs about the same amount as a cig lighter. Just doesn't make any sense to shoot gas everywhere and have your hand right next to that flame just because you don't wanna get a $3 tool at Lowes when it's convenient
galvanized pipe is a bad thing to cut with a torch- it can make you really sick with flu like .....propane and acetylene need different pressure settings - propane needs more oxygen pressure
If you had a track torch you could see how clean propane cuts . With my victor set-up you can see the reflection of your thumbnail when held against the cut edge.
Watch this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-f2amO0T3vkQ.html The reason your cuts are bad is that you're oxy/prop preheat flame is too weak, and you likely don't have the pressres set properly or the tip you are using. Consult Smith's chart for pressures on the oxy/propane tip you are using and set your regulator accordingly. Then watch thevid I linked up and see how to set up your preheat flame. It should roar a bit, wheras you are setting it up like an acetylene flame. Finally, hold the oxy/propane tip further from the steel, around 1/2 to 3/4 inch or so. It will preheat faster than the acetylene flame. Using a 1/4" tip on 1/4" material I can start a cut on a cold 1/4" steel plate in about 2-3 seconds, cut at a speed of an inch every 2-3 seconds, and the finish cut has no dross or corner rounding. It literally looks like a high quality plasma cut.
Can you use the acetylene regulator tubes torch and arrestor on the propane cylinder? In other words is all you have to change the brazing/heating and cutting tips?
There is a huge difference when cutting. I never had blow back with acetelyne but God I have blow back with propane. Propane burns at the melting point of steel. Acetelyne burns way hotter. Way easier to cut steel
It is not the fuel that cuts the steel, its the oxygen. The ignition temperature of steel is 1,500f less than the melting point. Acetylene is effectively "sharper" than Propane But Propane has more energy by volume.
Starting propane torch takes a bit of practice should turn both at same time. Use a striker ,and wear some damned gloves! Watching you cut galvanized pipe I can feel the metal fume fever coming on!
Can you please help me I switched over to propane for my cutting torch and I bought a propane cutting torch tip, and I set it all up and let the propane, but when I apply the oxygen it goes out, why?
Hop over to serious welding forums. RU-vid is not a serious welding forum. Your settings will be different and lighting is different than acetylene. Abruptly opening your oxygen valve will tend to blow out your flame.
thats the downside to propane its a little miserable to use, but if you only pick the torches up once a month then its fine.. you need to be ginger as can be on the valves, and jump back and forth valve to valve with like 1/64 turns.. acetylene you can crack the fuel open light it up and crank you oxygen in all at once, propane you have to light a tiny flame add a tiny bit of oxy a tiny bit of fuel back and forth and back and forth working up to the required flame
im in eastern canada pretty sure i pay like 80-100$ for each tank and theyre size 15/16 around 100cuft, propane is 1/4 of the cost of acetylene and the acetylene is 2/3 the cost of running O/A.. so youre cutting the cost in half to run propane, not to mention you only need the oxy tank not the acetylene on lease
@@N4ANE Yeah but you documented your unsafe practices on Y/T and your insurance company will probably deny you coverage over it. What is so frigin' hard about making a cart or using a short piece of rope for temp support?? I have seen the aftermath of an O2 going airborne it missed a car full of kids by a few seconds...
I think most of us have made the mistake of burning our sausage on hot metal before! Luckily most of us only do it once haha, if we don’t learn I’m sure they probably are doing the world a favour for castrating themselves
4:09-A Bic lighter. Really.? One of the first things you learn is to NOT to have a Bic lighter on your person in a welding shop, let alone light a torch with one. Next video please. TD#7. Thus far there have been 54 novices giving you a TU. Hope that they are not dumb enough to apply what they see here on this vid.
The guy that had to Bic lighter in his shirt pocket with his smokes while welding a spark got in there melted through the plastic and exploded right over his heart throwing his heart out of rhythm (that split second that's all it takes) killing his ass. I'm no safety cop by any means but I've been around the block long enough where there's some shit I just refuse to do.
@@rcstuff7718 the lower heat isnt really much of an issue, barely notice it.. but the propane is harder to light and goes out easier if your using it everyday and make a living off of it the acetylene is a nice convenience
Agree. Only reason to go propane is cost. Acetylene is way better flame and easier to use. I fill #4 acetylenes for like $55 dollars and dont go through them that much anyway... Maybe if your doing a lot of cutting scrapping things or something, but as a normal weld shop, use the acetylene.
