🔥 Flame Cutting with Oxy Acetylene

Learn how to cut steel freehand with an oxy / acetylene torch and a burn bar. A burn bar is a tool you can build that will help you cut straight lines and bevels nearly perfect.

I glad you cover the Oxy/Acetylene torch I feel it is an over looked tool that is still very popular especially with the home shop. I would like you to cover the torch in more detail if you could. pressure settings, tips sizes, flame tip adjustments. From what I've seen on you tube is many welders assume that using a torch is common knowledge. Maybe a series on torch usage 101 would be good.

Bob is really knowledgeable and I enjoy watching his videos, keep this guy around.

When I was learning to oxy fuel cut around 45 years ago we had to use a ascribed line with dot punch marks along it. After cutting we were expected to have just half the dot punch marks left. if the whole mark was there or none at all we had to do it again until it was right.

Great demonstration! Always prided myself with my torch cutting work. My go to guides for over 40 years are a 2' and a 3' foot one. Made with 6 sided drill stock from jack hammers with 1/4" steel flat tabs welded on along with 2 die maker magnets welded on the 2 footer and 3 on the 3 footer. They rods are positioned so one pointed side is facing towards the side that the torch will be guiding on for straight down cuts and also the angle can be used as a bevel cut guide. Tabs allowed the bar to be clamped when needed but most of the time the magnets did the job on steel. I must have made over 20 of them for guys when they saw me using mine. My go to torch has always been my favorite Oxweld W17 combo torch, which no one else was allow to use, which teed off a lot of guys- but too bad. I notice your guide was also marked instructor only. I can see other torch videos you can make showing how to cut off bearing races with out ever nicking the shaft or cutting off frozen nuts without ever touching the threads or burning out bushings controlling the oxy. by feathering the lever. Your students are very fortunate to have an instructor that is not only technical but very field experienced.  Thanks Ed K. Cleve. Oh.

Hey Bob just wanted to tell you that i really enjoy your videos ive spent over 30 years as a pipefitter in that 30 years ive had to weld and worked around some incredible pipe fitters and fabricators. Ive never been near a strong a fabricator as i am a PF there is a big difference. Im currently trying to become a CWI I take a 10 day seminar and a test in may. Im doing the 1104 i think you would be great at doing seminars to become a CWI. I caught your video where you welded cupons and did a bend test root and face and got so much out of it. When im studying and want to refresh my memory on a welding process or whatever ill look at one of your videos and always get something out of it that always applies. Thanks for that. You are definently one of a kind and I mean that in a good way keep those videos going you are helping alot of people out there Bob including me and im a 51 year old craftsman.

You do an excellent job, Bob! I have the "high speed shimmies" too. I like to call it "auto oscillation" or "whip-n-rattle".

[MakeItWithCalvin]

Clean tips makes things so much nicer for welding & cutting with a torch! Can you guys do videos talking about the max withdrawl rates for oxy/acetylene rigs and talk a bit about what different sized tanks are useful for. That would be SUPER helpful!

[lordphullautosear]

Back when my Old Man was a union carpenter, he showed me how to mark stock accurately. Sharp pencil, pointed like a wood chisel, and each location is marked in 2 slightly different directions, so that one knows to measure from the point of one "V" to the point of the other.

[eurdisgonzales]

I like you style. I find it very, extremely useful. Taking welding at a Trade Tech School in Vernal, Utah. Thank God, I am not in the Big City anymore. I'm originally from L.A. through the Pandemic. Now here bcz of my family. Wanted to be next to them. Having an aging mother. Met a kid from Klamath, Oregon. Interesting how it is a small world.
Thank you very much for all that you do. :)

[wcompto]

hey Bob, I just about fell outta my chair at the end of your video. I also worked at Columbia Plywood on the graveyard shift as i went to O.I.T. (probably 1979-ish). Coincidentally, i am now retired and learning how to weld as a hobby. Small world, huh!? I enjoyed your video and look forward to more. Thanks for the

[brxtmp]

I had earlier unsubscribed but returned and remain since Bob has started instructing. I find his style, depth of knowledge and experience, and demonstrated skill are second to none.

"blowin up the corner of the pentagon" ... aaaand demonitized.

[richmac]

Really enjoy your video's and all the helpful hints. I don't have any formal training so everything I do is sort of trail and error which is not really ideal. Love the idea of a burn bar. Most of my oxy cuts are done by hand and like you my steadiness has diminished as I've gotten older and don't always look like I'd like them to. Just learned something new watching you - I've never preheated the entire cut before hand which apparently I should have been doing. Thanks again look forward to your next video

[waderedsox]

i had no idea you could cut that fast and cleanly with a holy crap

[ChrisB]

Most useful info Paul - I have tried to switch to plasma cutting but still think back to oxy cutting days - must say if attention is paid as you described, it truly can be a super method... mine no way as good as yours. Must try it again!

[ramchillarege]

Excellent. Thank you.. now I need to watch all your videos. I have been welding some, but now want to get better at using the torch.

[beardly]

I ended up going with Oxy/Propane. I was reading through my Home Owners Policy and according to it (SFarm), I can't have Acetylene on my property. Something to think about for those using or considering an Oxy/Fuel torch.

[AH-ihwd]

You can sharpen soap stone with a regular old hand crank pencil sharpener. I've one mounted to my welding table.

[cjsaders]

i like Oxy / Acetylene gouging over arc air after a older journeymen showed me how to do it so much cleaner and easier then arc air i found

[alejandrowasinger]

Thank you man. I have this torch and never I tried because I am worry of any recoil of the flame. Could you share any video that teaching to operate this kind of torch safe?
