I worked in a shipyard for 37 years, that's all we used, propane, cut everything thickness wise!

Great video guys. I think you are right on not knowing how to adjust for propane is the main reason people say it sucks compared to acetylene.

I am new to oxy propane ... I bought a Victor medalist set and first time using cutting torch and it is making popping noise unless oxygen lever is depressed. Tried running 5/35 and 10/40 on gages no difference. When I light the propane, should I add oxygen and create neutral flame then repeat. I am nowhere near flame shown in this video.

My sentiments exactly these guys seemed to have there shit together and still having fun.Unfortunately you don't see that work ethic very often these days.....thanks Kevin T.

Used oxy/propane(also every fuel gas anyone can think of). In all the hand and burning machine torches i have used there are lower psi tips(usually for small repair shop folks), then within the same brand there are higher psi tips(thicker cutting by hand or typically CNC burning machine cutting. Have cut up to 10" thk. by hand and 26" and 27&3/4"thick plate on my burning machine. The coolest thing i have seen is oxy/propane with black iron powder injected/mixed with the cutting stream(iron powder runs 200$ a 50lb pail). That mix with either hand torches(often 4 to six feet long to keep you away from the spectactular flame/sparks/SMOKE) or machine torches that cut billets or ingots up to 4 feet thick!

Great video, you are a good teacher !

Thanks. Good info for a guy who doesn't know much about welding and cutting.

You did a fine job bubba !!

Thanks. I do appreciate the help.

Old but good video. I'm looking into getting my first oxy torch since my plasma cant heat metal or work outdoors during drizzle.

Damn dude, that's a helluva good cut! Never thought it possible with propane, but now I see it can be done. Good informative video man, thanks for sharing...also, those are some spiffy regulators and torch!

Excellent video! Thank you.

I have been an ASE Certified automotive and Diesel mechanic for overv 40 years. You are never to open the valve more then 1/4 turn. The reason is safety. You have 2000 psi in that tank, if your touch is lit and a hose ruptures or the regulator comes apart . 1/4 turn will save you. A fully opened valve you will not be able to close before the fire backs up. If the regulator comes apart with 2000 lbs of pressure, don't worry about the fire. The tank will become a rocket. And fly different directions. I have seen this happen before.

i look forward to watching your vid once i get to a computer! thanks for your time;walt

Excellent ! Thank you so much, sir

Nice job on the video! I also agree that Smith torches are #1. even if they are a little pricey.

biggest advantage is you can throw a propane set in the back of your truck , drive somehwere and dont need to wait for the acetylene to settle better for trowing in a pickup driving in the middle of bumfuck nowhere and torch cut scrap metall or rebar or whatever needs cutting i only use it for heating rusted tractor parts where propane is way cheaper than acetylene - usually also use gas rich flame to reduce oxygen cost its a less clean cut than my plasma cutter so i tend to avoid cutting with it except wherever there is no electricity ... i used it to heat and bend rebar thats to thick to cold bend with a pipe extension with it

I like that wood stove you got in the corner bet it keeps you nice and toasty. nice video

Most really large industrial cutting/scarfing torches are designed for LP, not acetylene. LP works well. Having both options is handy. You can use an acetylene regulator with a CGA-510 fitting on a BBQ jug because the internal threads (not the external threads for the plastic nut) are designed for it, but do NOT exceed the capacity of the OUTPUT gauge or you can damage the gauge (guages are cheap though). US-made regulator soft parts are fine with acetylene and LP but if in doubt contact manufacturer tech support to confirm. Perhaps long ago R hoses didn't get along with LP but many welders have used them without problems, self included. If you buy new hose, get T. For more info I strongly recommend the Weldingweb and Miller forums. Worth noting is if you want more flow for high flow cutting needs you can buy the larger LP cylinders which do not have OPD (Overfill Protection Device) valves.

I didn't get the part about the difference in the regulators can you use acetylene regulator for propane I've never cut with propane just the fact that you can go get a bottle at anytime is the only reason I would use it

thank you, was very helpful

great video!!!!

An acetylene tip would be a no go with propane if you notice the tip is recessed for propane which allows the flame to burn with acetylene it would just blow itself out. Propane tips also allow for the needed additional gas flow.

I'm in HVAC/R and yes you can solder & braze with oxy-propane.

Quality acetylene regulators have soft parts rated for LP (which is why their rebuild kits aren't gas-specific) but the LP regs go up to much higher pressures. (That difference is due to the heavier spring.) Take my word for nothing (this is KZread after all) but do check with your manufacturer tech support. They are happy to answer! Also check out the Weldingweb and Miller forums for tons of information because KZread is mostly just good for demonstrations. I've used LP and acetylene for many years and rebuild my own torches and regs per factory guidance. (Don't fucking dare rebuild regs without study because high pressure oxygen is no joke!)

Hold on a second there young feller, the pressure in the propane tank is a function of the temperature of the liquid propane. As long as there is liquid remaining the pressure will reflect the temperature. You tell how much propane remains by weight. When the bottle is filled it is done by weight. It doesnt matter if the tank contains 1 pound or 25 pounds, the pressure will be the same at a given temperature, in the neighborhood of 60psi at room temperature. Look up the temperature/pressure chart for the refrigerant R-290, propane for specifics.

@Welding2012

Thanks feller, you are correct; pressure is not the correct way to measure. If you notice I used the phrase if I'm remembering correct. That's because when I got the setup it was in August so the ambient temperature was probably around 85 to 90 F at that temperature the vapor pressure of LP would be 135 -140psi that is likely what I was remembering (however incorrect it may have been). Based on my pressure gauge the shop temp must have been in the mid 40's which is reasonable for January. Thanks for the information.

I would say as good as any flame cutting method I mean as far as piercing it is the same procedure as with acetylene just need the correct size tip and a steady hand. One thing i have found with cutting nice small diameter holes is start in the middle pierce through and keep tracing the outside of that until you reach the desired diameter at least for me this works well. Good luck!!

Back flash arrestor is definitely a good thing.....

Great video. why did you get rid of this system?

I'm thinking of getting an oxy/propane rig instead of acetylene just to heat rusted nuts. Would I save any money in the long run?

I am not sure exactly but you will use a lot more oxygen then with acetylene however the oxygen is much cheaper. I have never really crunched the numbers but I want to say the O/P uses almost twice as much oxygen but don't quote me on that.

sorry it is a bit off subject but is that de walt grinder on the bench at 6.08 any good? I was thinking of buying one as a replacement for my current one. Thanks Great vid

One of the big advantages is the fact that the plant that provides 80% or so of the US Acetylene burnt up last year and will not be back in production they say some time in 2012. Until then Acetylene is way more expensive than can be afforded.

you need a low pressure setup is the optimum way to use LP

Thanks i enjoyed it. do u have acetelyne too?

hello,i was wondering if you can buy propane tips for pipular acyetaline torches,or do tou have to use a totally different torch? also,cant you still use oxy/acy. hoses with an oxy/propane set-up? i have a buddy who has used propane/ oxy now for many years with a large industrial torch/ has used it to cut thick steel,he told me i dont need to switch anything,but he may have not set it up himself,so i wanted to ask you what all i would need to change from my ovy

Grade R hose is for acetylene only and grade T is for any fuel gas!!! Not the way you said!!! I'm just telling you and other people thats what my welding store told me look it up!!!

Where can I find psi chart ... I'm using oxy propane but went through 2 oxy tanks in a day... I'm running a #0 propane tip.... Help quick please this scrap job is going to cost me a Fortune going through oxy like this...

How is Oxy-Propane for cutting scrap steel? The place I deal with has been raping me on acetylene. Also the valves on the past two acetylene tanks I have got leaked weather the valve was on or off and Im still fighting with them about it. Its not often I have to cut up scrap but when I do it would be nice to know that have gas there when I need it. I am set up to use both Oxy-Propane and Oxy-Acetylene.

Some information may not correct in this video. According to my knowledge the Propane + Oxi combination is hotter than Acetilen+Oxi. Unfortunately by propane the burning process is slower, thus it is not able to apply enough heat on the workpiece.

@Welding2012

I would have to disagree with the statement above; while all of the information in this video may not be 100% technically accurate, the statement made above is incorrect. The oxygen-acetylene flame burns at approximately 5600 degrees F, while oxygen-propane burns at approximately 5070 degrees F. As for the not being able to apply enough heat, the kindling temperature (temp required for cutting) is approx 1600 degree F well below the temp of both gas mixtures. While the oxy-propane may take a few seconds longer to reach the kindling temperature (due to being approximately 530 degrees cooler), once the cut is started the burning or cutting of the metal can actually continue without the heat from the fuel gas. I hope this helps to clarify things.

How thick can you cut with the stock tip with that setup?

you should weld with it too

So what happens to all the carbon atoms in the propane? C3H8...

cool

you got that mixed up... Grade R is for Oxy/Acetylene and Grade T is for Oxy/Fuel gases (incl. Acetylene)

you cannot weld with oxy-propane, you can only weld with oxy-acetylene, due to the carbon-dioxide shield that is produced, as well as that oxy-propane and other oxy-fuel gases will produce a lot of hydrogen and thus leave you with a porous weld (hydrogen inclusion).

Would you be willing to make a video brazing with oxy propane? Also have you ever tried brazing with just plain copper electrical wire? I've seen that it can be done by other youtubers but I would love to see if it's possible with an oxy propane setup

Unfortunately you can't weld with oxy-propane it doesn't get hot enough also when oxy-acetylene burns it produces CO2 that shields the weld, with propane you do not get that so the molten puddle has nothing to protect it therefore it is impossible.

YOU DID NOT STRESS WHICH GAS TO TURN ON FIRST OR TURN OFF ON THE TORCH

Once the cut starts, the fuel you use makes no difference, the oxygen alone is what does the cutting. Once the cut starts you can literally turn off the propane or acetylene and it will still cut.

YOU ARE WRONG. you can weld with propane. all industrial cutting is done with propane. there is no carbon put in propane like acetylene so it will not be as strong of a weld. also cutting with propane won't harden the cut edge making machining much easer

Sorry man can't weld with oxy-propane it doesn't get hot enough also when oxy-acetylene burns it produces CO2 that shields the weld, with propane you do not get that so the molten puddle has nothing to protect it therefore it is impossible.
