For most thicknesses 5psi is good enough. Never go above 15psi as acetylene is unstable and can blow up.

I open the valve on my Oxygen cylinder just half a turn. The reasons being that half a turn is sufficient for most welding jobs and that it's much quicker to shut off again should an emergency occur.

Excellent video for a quick brush up on the flow values for each tank. Thank you 👍😎

I'm a beginner to this so I followed your video and broke the flow gauge. I bought a used set and opened the tank like you said. What I didn't realize is that someone had screwed the adjustment all the way in so 2000psi went to a gauge designed for 30psi and broke the gauge. Since this is for beginners, maybe you should tell beginners to back out the adjustment knob all the way first, then open the main valve and then adjust the acetylene to 5psi.

Hello and thanks for watching. Sorry to hear about your mishap. That said, I do cover adjusting the regulators in the video and I find that students often leave the regulators turned all the way in periodically. Also, when you buy used equipment you should always check the operation before you leave. I have bought used equipment before that was broken and fortunately I was able to fix it.
@onemoreboat Жыл бұрын
@@kosworkshop I just wish that this video was really for beginners. If it was me I would have said to never assume that the pressures are set correctly or damage can occur. I would also tell beginners that you always back the regulator knob all the out before opening any tank for the first time. Lesson learned for me

Open your Oxygen valve completely until it seats, if not it could leak. When done back out your regulator adjustment screws.

Don't open the acetylene more than 1/4 turn so it is fast to close. If the acetylene regulator does not have a valve wheel, like this one apparently does not have, I would recommend a clamping wrench, like Vice Grips, that are set to lightly clamp onto the control shaft (which is usually square) so that it is not likely to fall off or get easily knocked loose when you are in a hurry in an emergency. Now there may be some welding oxygen cylinder valves that are different now as it has been some years since I taught welding, but all that I have seen, including the ones in my shop right now, have what is called a "double seal" valve. That is a valve the is turned clockwise, hand tight, to close off the flow out of the cylinder. When you open the valve, turning it counter clockwise, all the way until it stops. Then snug it hand tight in that direction. Since oxygen is very high pressure, if the valve is not hand tightened at the stop in the counterclockwise direction, the HP oxygen may leak out around the valve wheel shaft. The valve has a close-off seat at both the fully closed position and the fully open positions. A little leak of oxygen is not likely dangerous, but is is frustrating to get ready to do some work and discover that the cylinder is empty. I just paid over $200 to fill a large cylinder that had leaked down just that way!

I should say, I have used Oxy Acetylene since I was 15, I'm 52 now, but I have never set up a system from new. Given I'm an autodidact, I always read everything carefully and follow instructions, in the manual for my new set up, it was clear, open the Oxygen all the way, "DO NOT TURN BACK A QUARTER TURN", for the very reason you explained. These are really important safety instructions because while Oxygen itself isn't flammable, burning is in fact rapid Oxidation, given it supports combustion, and in fact is necessary for combustion, it's really important to not let it leak out into the room. You're not allowed to smoke around Oxygen for a reason. I checked the comments to always see who has something more to say about the video, I appreciate your comment, I was wondering when this guy said, "turn back the oxygen a quarter turn if you want", that would unseat the valve and potentially allow Oxygen to escape as you said. I appreciate videos like this but the reason I've survived contracting for so many years with no licenses whatsoever, including my auto shop for years, is because I always get the book, I always double check, I always to things right and anyone who wants me to do things half assed is told to hire someone else. Here I double checked and I appreciate your wisdom and the fact that you taught welding. When it comes to youtube videos, my policy is watch multiple videos by multiple people and only accept that which is universal among all of them, if something isn't universal that is important or a potential safety issue, continue with books or code or manufacturers recommendations as they never want to be sued. "Good Enough", is the statement read out in the court case. As well, things like thread sealant, for example, if it's required or recommended, and I always check, I buy the best there is, no budget whatsoever and I make sure it's rated for the purpose at hand as thread sealants are not the same. This, in fact, is why so many people have so many problems doing things themselves, they are either to lazy, impatient or cheap, or all three, and don't bother with the little details, always a recipe for disaster. At any rate, the video was pretty good except that one comment, thank you for your comment, it really clarified that for me, although would have still followed the manufacturers book anyways but this leaves no doubt for me.

Is there any way to tell if the oxygen tank is empty. Other than just opening it
@kosworkshop17 күн бұрын
@JamesWhite-tg4kw If your gauges are accurate it should reflect how much psi is left in the bottle. That’ll give you some idea, but it’s difficult to tell by weight.

This helps stop acetylene from entering the oxygen bottle and sitting at the bottom of the oxygen bottle. Once settled it can cause an explosion when striking the bottom of the oxygen bottle. This is why it's recommended you have a larger oxygen bottle than your acetylene bottle.
@Mike40M4 ай бұрын
When I pause, I shuts off the bottles. Leaves pressure in the hoses. Checks the gauges. When resuming I check the gauges to check for leaks. In my country flashback protectors is mandatory. Though never experienced a backfire in sixty years.

i have a question that im sure many had asked themselves ,can i adapt that torch tip to a propane can? .the small one that walmart sell ,the green smal can for gas camping burners ..my two torch does not wants to give me a fine point on the flame to polish acrylic ,im thinking that if i can adapt this tip on my torch it will burn a tapered flame ?..if its a stupid idea please forgive my ignorance

It’s a very interesting question. However, I wouldn’t recommend trying to convert it. I would see if you can find the type of torch tip designed for that application if it were me.

This is actually a good question. I would say it depends on how much you use your torches. However, I have received some bottles that are leaky and some that were not full. That said, I guess I’d say that there are some variables to your question.
