I wondered why you opened both tanks at the same time. It became clear the reason was you are a careful man, as I am. You were checking the new installation of the gauges for security and leaks. Thank you for being as basic as you could, it was a great review. My wife and I had a great laugh at your expense, tho, as we noticed the total devotion to neatness and organization of your shop area!!
Such a great video, thanks! I’m a beginner and have been worried about doing this! My instructor recommended flashback arrestors; curious why those weren’t used here?
So much wrong on this. The valve on the acetylene should even be left hand thread. The valve on the oxygen should be opened all the way. These tutorials should be 100% correct.
@@FerrousPhoenixNice video. A few questions if you don't mind.... I have a small oxy/acetylene setup (10 cu. ft. acet & 20 cu. ft. oxy). I bought it to mostly just for heating up rusted nuts & bolts as I work on cars quite a bit. I read online that with my setup, it's not safe to use any size rosebud bc of the unsafe acetylene flow rate. If this is true, what size copper welding/brazing tip should I use? I have a #0, #1 & #2. Is #2 big enough to do it or should I go a bit bigger? Also, what should the pressures be for the appropriate tip size for my application? My other main question is ...Would a small Mapp pro/ oxy kit be cheaper and/or more efficient to run than the oxy/acet setup? I read that the tiny oxygen cylinders run out too quickly on these setups. However, if there is a way to hook up a larger oxygen tank to the small Mapp pro /oxy torch kit, then I would LOVE to do that. Is there anyway to do that safely? Thanks in advance..
The last video I watched said that acetylene pressure should be 5-7psi and oxygen 10-15. If I'm trying to use the cutting torch are these pressures right?
That's about what I set my pressures to. But if your cutting really thick steel, you might need to increase them. Just make sure acetylene never gets pressurized above 15, it becomes unstable at higher pressure.
Does the psi for cutting with oxy acetylene vary with tank size? Like my portable kit you buy at Lowe's for like 300 bucks. Do the pressure settings change when you move from the baby 10cu ft to a mid class 75 cu ft tank? The reason I ask is my regulators use the tiniest A fittings and I bought adapters for A to the next size up and very common B fittings. The hose ID is 3/16" and I bought a little longer hose. I've never had issues before changing to longer hose. My flame just keeps going out as I'm heating up bolts that I want to cut off. Could it be that though the regulator reads 5-7 that I might need to crank it up to like 15 to get 5-7psi in the larger hose? Thanks
No, the pressure you need is determined by the size of the torch's tip. A larger tip will need a higher pressure of oxygen. You only need enough acetylene to get a decent flame before you crank the oxy
