Hi I'm an HVAC mechanic. It's good to see videos on basics. Sometimes when you're learning a trade there is so much to absorb. Young mechanics are afraid to ask older ones for fear of being ridiculed Thanks again for the video.
Thickness of cooper matters when determining oxyacettlene p. Oh, and its dangerous stuff. Never exceed 15psi pressure on oxyA. Thinner refrigerant lines can be brazed w/ a pressure of 3 or 4 and a tip of 00 or 0.
HLCharley, Hate to make a bad review BUT,,, bad practice is,,,, :O( never have tanks free standing particularly when no screw on cap, is on the tanks. Other words when regulators are installed. If a tank tips over and breaks off the fitting, or gauge on the top you now have an un guided missile with 2000psi exhausting from oxy tang that will propel tank through anything in your shop and take it all out through the shop wall and into the street. Hoping not Charley with it! Always should have a chain, usually, wrapped around both tanks connected to a wall or bench to prevent tanks accidently tipping over. Just a friendly tip.Toolman
ALWAYS, ALWAYS, ALWAYS... ALWAYS strap or chain your tanks to the wall or a stable cart!!!! Hardluck Charlie doesn't like to ride bottle rockets, and doesn't want anyone to get hurt either. Thank you for commenting.
I take it for granted the gauges on the right show you how much pressure is in the tanks. How can you tell when the tanks need to be refilled or changed out what are the recommended pressure ratings for the two of them when they need to be changed out. Thank you for your time and the video was very helpful for me
I was under the impression the reason the oxygen regulator needs to be open all the way is to have it backseat. Is this not the case? Seems turning it back at all would defeat this purpose
Hey Charlie, JBbolts is correct. Go read page 6 again because it says to open the oxygen valve all the way. It says nothing about turning it back clockwise a little bit
Hello,my acetylene tank is threaded outside and not inside like the one shown here and my acetylene regulator is like the one you have in this video although it is the edge model by Victor Technologies,how can I connect this regulator to the cylinder when both of them have external threadings.Thanks and I look forward to hearing from you.
Hi, sorry it took so long to respond. I suggest you look up a welding supply company. They will be able to help you much more than I. Good luck to you!
@@ballou1777 Adapters are available at your local gas supplier and online. THE PLACE TO LEARN ABOUT DETAILS IS NOT TH-cam. I recommend the Weldingweb and Miller forums, and migwelding.uk for those not located in the US. TH-cam is for watching technique. Forums and factory literature are for detailed info. Take a clear pic of your acetylene cylinder valve and regulator or bring your regulator with you to your local welding supply.
Acetylene tank caught fire at local shop, workers dragged it outside and let it burn all day, all safe. Big farmer propane tank caught fire, firemen put water hose to it, tank burst and killed 4 people.
My dad would agree with you,. He and I used to argue about this. The reason for not turning the oxygen wide open is for safety, in case a quick shut-off is necessary. The torch gets plenty it needs to operate at a half turn or two twists on the bottle. Thank you for mentioning this. It's an old myth that can lead to disaster in a hurry. But I suppose it is a matter of preference and what argument you prefer. Thanks again for writing.
Instead of being "sure" LOOK IT UP. There's no need to guess! I rebuild my own regulators and torches per factory tech data and ran a welding school toolroom (including repair and maintenance but not regulator rebuilds because of insurance reasons) for several years. All the info is easily found online. Here's a Victor/ESAB reference. See page 5-23: www.esabna.com/shared/documents/litdownloads/56-3260.pdf "Slowly and carefully open the oxygen cylinder valve until the maximum pressure registers on the high pressure gauge. Now, open the oxygen cylinder valve completely to seal the valve packing."
Always link official references when doing safety related videos! Otherwise decent video. All viewers SHOULD FIND AND READ official references when industrial gases are involved. You'll thank me later. BTW rebuilt regs and torches are good as new and should last decades. I have one Harris cutting torch from the 1930s on original seals that held over 150psi nitrogen when I pressure checked it. (Only use INERT gas for pressure testing and follow factory literature!)
Thank you AGAIN for making the point that is now being beaten here like a dead horse. But none the less,... ALWAYS, ALWAYS, ALWAYS ALWAYS!!!! RESTRAIN YOUR BOTTLES FOLKS!!!!! Apparently we can not stress that enough here. My omission, my apology. The video was shot with the bottles standing loose simply to more easily video demo the regulator adjustments. I should have put them in my cart, but it would have made the video shots more difficult. In the future I will be more diligent when making tutorials that should always stress safety first above all else. Thank you again.
hardluckcharlie informative video but no need to make stuff up about the cart getting in the way because your hand covered up the gauges the whole time you set the pressures. Next time just shoot us straight.
Wrong again, this is where everyone is wrong, Oxygen tanks are opened all the way, "DO NOT TURN THEM BACK A QUARTER TURN", there is a valve seat on Oxygen at the top and the bottom to prevent leaks, if you turn it back you defeat the valve seat and you can leak Oxygen. There's this old standard, which I use but not for Oxygen tanks, to turn a valve back a quarter turn to prevent and unnecessary wear on the valve and everyone is going with this ideology where it shouldn't be used. I'm setting up a new system for the first time, although I've used Oxy Acetylene for years, I've never set up a new system and thus, I read every word and now I'm watching videos as well, I make sure I don't miss anything and on the last video, as I never watch just one and throw at anything people don't agree on, a welding instructor commented below, as I was wondering because to turn back the Oxygen valve is in direct contradiction to manufacturers instructions. The welding instructor made the same comment and thoroughly explained the mechanics of the two valves, the Oxygen having a sealing valve seat at both the top and the bottom to prevent leaks when operating as well as when closed for storage. If you turn back that Oxygen valve a quarter turn, you defeat the seat and the seal at the top of the valve and could leak, it's that simple.
FYI, I've worked in many places, never "assume" that things come clean or blown out or assume anything at all, this is explosive gas, follow the procedures at all times to the letter.

Thank you for the refresher on setting up the guages. It's been 35 years since metal shop.

great video. straight forward. visually perfect...I could see everything clearly. You give the the information that your title says. thank you!
Thank you so much!
I found this video very informative and enjoyed the emphasis on safety. Good job!
Thank you so much.
thanks for the tips. I'm a entry level hvac and this really helps
Thank you. We appreciate the comment. Good luck!
You do know you never do oxygen before acetylene right??
straight facts well delivered thanks 👍
Be sure to crack the tank valves to blow out any debris before attaching regulators.
Thickness of cooper matters when determining oxyacettlene p. Oh, and its dangerous stuff. Never exceed 15psi pressure on oxyA. Thinner refrigerant lines can be brazed w/ a pressure of 3 or 4 and a tip of 00 or 0.
fantastic

I take mine in for refill when I can't get a proper flame. Or before, if I know I'm going to run out during a project session. Thanks for asking!
@@hardluckcharlie what is considered a proper flame it is there anyway you can show off photo of what it looks like
Thanks
No flashback arrestors????
No flashback arrestors?
Thanks for the video. Can you provide a link to who rebuilt your regs?
OXARC is Spokane, WA. Thank you!

Wow, that's too bad. Take care!
I'm pretty sure that the Oxygen valve needs to be turned all the way open.

The Oxygen valve is a type of valve that needs to be turned all the way open in order to seal.
why was the acetylene gauge dropping (from 160 to around 50)?
I noticed the exact same thing hahahaha
At 7:00 it's up to over 200
No Teflon tape on the hoses
No, don't need it.
