Ken, I just came across your tutorials on Welding and I was fascinated by it. I plan on doing some art sculpture out of metal & will be welding in the near future. Now that I have found you, I will be listening and watching to learn something I may not already know. My father was a welder/steam-pipe fitter for 42 years when he finally retired. As a child, my father would teach me different techniques and we would create all different size animals. We went to the junkyard first and quickly found all of the parts( nuts, bolts, small pieces of sheet metal, rods both, threaded and smooth). That is where I got my love for junk stores and Junkyards. I am very lucky to find the things I need for projects and that is mainly because our society is used to being a "throw-away society". You need to use your imagination to take an old toaster, take it apart, and create something new out of the parts. Thanks, Ken!!
To put a quick silence on the left hand thread confusion - LEFT HAND THREAD IS ALWAYS MARKED ON THE NUT (every edge of the hex is notched to indicate it is left hand thread). This is also often only used on the gas connection side.
Excellent video for the new oxy acetylene user Ken. Its unfortunate you get some negative comments like shawnkiller, and others who apparently have no life, except to post some over cautious stuff, perhaps just to prove they are alive? There are many unhappy people running around with negative remarks. Been oxy acetylene user for more than thirty years, and I appreciate your tutorial. All the best and keep the good work coming.
Might want to suggest using a fixed wrench to turn the gas on/off,during the initial blow-off,. If you have a problem switching the ratchet from open to close your small unvented room could fill with gas. Good reason to first check your area for any ignition or flame sources. Like a pilot light in a gas appliance. Good concise video.
@Harness W. This vid is chock full of wrong and very dangerous information. Way too many items to list. Please watch some of the other vids here before using a torch rig.
Thanks for the upload. Couple points I'd like to add, 1 open oxy cyl main valve SLOWLY to protect regulator, and backseat it! ...stay out of the direction of the reg adjustment screw should it become a projectile, 2: acetylene wrench is to be non-ratcheting, opened 1/4 to 1 turn only and key left on cylinder until done.
@@gunchief0811 That torch handle has flashback arrestors at the bottom where the hoses attach. You can hear it when he was running oxygen only without the tip, that rubbery burbling sound... Better to have them there than at the regulator. Heard a story long ago where a guy broke his jaw, and got one eye damaged when hoses exploded...
Very good job! Was looking for exactly how to set the pressures on the tanks. Other videos just assumed I knew how and only gave me the numbers, not showing how they change when the gas is on. Thanks!
Acetalyne gas is a stabilizing agent for the gas cutting. It's also combustible so it blends well with oxygen gas to create the gas hot enough to cut steel... Beautiful stuff I Love it!
Most Excellent. Thanks so much for your time. I have the same Victor Rig, but the instruction manual is no where as satisfying as seeing it done "in person".
I often find it's best to operate a welding torch in a closet full of combustible material. lol..... Just busting your chops. Great video. I'm a noob and need some instruction.
excellent video.great presentation.donot mind the comments of people.rather than critisizing others they should make their own videos to prove them,healthy critsizm is good but otherwise go prove ypurself first
@nauman This vid is chock full of wrong and very dangerous information. Way too many items to list. Please watch some of the other vids here before using a torch rig.
Thanks Ken. That was a thorough vid on the basics of starting from the beginning to lighting the torch. I liked the purge routine you did. I had never thought the debris in all the places that you described. I shall start using the same practice when replacing bottles.
Good vid, Ken. What about flashback arresters? Also, like the water and fire extinguisher. You're in rather close quarters with a lot of flammable stuff around. Ventilation? Also, I always recommend NEVER look at the flame. Shade # 5, even for just a short moment. Really bad habit to look at the flame without filter eyewear. Like cracking the tank. Nowadays the company I use puts a plastic sealant around the opening. But it's best not to trust those guys. Crack the tank. Also, letting down on the pressure afterwards. I rarely do that. Something I'll start doing. Like to hear more about that.
I'm just a carpenter who does some metal work as needed but I'm really alarmed by a number of things you've put in this vid. One, acy. thread (like propane and most, if not all flammable gases as far as I know) is usually backward. You should probably know this isfyou are doing a vid on this topic. If you are using an off brand or ancient bottle and regulator set up that has threads that don't match current safety regs, no gas supply house will refill your bottles and it's really dangerous to take a chance on them falling into the hands of someone who isn't familiar with your set up/aware of the danger. Even with different size nuts, someone may be tempted to cobble an adapter together and blow themselves up. Did you think to mention an inspection for any grease/oil on oxy. threads and system and why? Two I would never consider using a separate wrench rather than a bolted in place handle to turn a tank on/off. The split second(s) it takes a panicked person to find the wrench, fit it in place and turn the valve the right direction may be the time it takes to head off a disaster. I never open the valve of a tank more than just enough to allow free flow. Again, the split second it takes to turn a valve handle several more revolutions than necessary for adequate flow might be the time needed to avert disaster. Three, the torch user needs to know the type and size of torch handle and tips and use the mfr's. tables to look up the proper acy-oxy pressure for that specific set up, material/thickness being used. I know of no tips that use the 1 to 2 ratio that you are describing. I'm astounded you just shoot from the hip with a general 1 to 2 rule of thumb and advise others to do the same. Just off the top of my head, a Victor size 0 oxy/acy cutting tip uses 30-35 psi of oxy with 3-5 psi of acy but I of course check the mfr's table every time I change tips or use my torch to match the tip size to the thickness and type of material being cut. Not only is it safer, it makes a HUGE WORLD of difference in speed, economy and quality of cut or weld. Properly sizing the tip, gas pressure to the job is the difference between cutting a board with a sharp power saw or a dull hand saw. Four, Showing novice users that it's ok to randomly turn your oxy up to 100 psi is a bad example as is using a torch or venting gas in an enclosed space. I'm out of time and there are way too many issues in your vid to address. Acy. bottles should be let set for 24 hours if they've been turned on their side, NEVER, EVER use synthetic gloves instead of insulated leather welding type gloves (or wear any type of synthetic garment) when using a torch, any contact with hot metal will not just burn you, it'll melt the gloves into your skin producing a far worse injury than just a burn. Using a torch in an area that is full of stuff that could catch/sustain a fire is a no-no. What about eye and lung protection? You would solder or perhaps braze, not weld copper tubing and a propane plumbers torch is quite sufficient for sweating a copper pipe joint. The more I think about all the wrong/missing information in your vid, the more strongly I want to ask you to remove it from UA-cam and leave proper training on something this dangerous to a knowledgeable professional. I appreciate your desire to make a video but this one is more dangerous than helpful. To all viewers of this video if he doesn't take it down: there are many, many sources of correct information about how to properly and safely use an oxy-acy set up. The gas bottle vendor, the torch manufacturer, the Department of Transportation and military manuals to name a few. Please get proper training before using one of these setups!
I know your post in nearly 6 months old at this post but I was thinking the same exact thing, I was pulling up videos to set up a list for a new guy at work to watch( to get visual notes with me teaching him other things) and god damn this vid had me alarmed I RECOMMEND NO ONE USE THIS VIDEO....there are so many more accurate and over all better tips and learning videos out there then this one, from the very get go when he wasn't able to be factual and concise I knew something was wrong...

Oxygen is always associated with green (tint varies by manufacture) - usually solid. Other gasses may come in a variety colors (although they shouldn't). Consider red line as your "gas line."
You need to bleed the acetylene first then the oxygen. also when shutting the torch down you should turn off the acetylene first so the oxygen blows out the flame.
Austin G. ABSOLUTELY WRONG! Turning off the acy. first allows the flame to burn back into the tip which fills with soot and needs to be cleaned much more frequently and hazards a flash back into the torch handle. The industry and professional practice is to turn off oxy. first. Whenever I hear a "pop" when a torch is being shut off I know I'm dealing with someone who doesn't know what they are doing and needs to be fully trained before I'll put them back on a torch.
+It's Matt if you are supposed to shut off Oxy first, why do all the Victor videos say to shut off Acetelyene first so that the Oxy blows out the flame?
@@KenTraining That's too high of a withdrawl rate from an MC cylinder. Shouldn't be more than 1/7 of the contents per hour. A size 0 tip set up properly should use between 2-4 SCFH. Which is a little high above the 1/7 rule, but it works for me. If you want to run 10 SCFH of fuel gas, then you need a B tank or larger, especially in cold weather. If you pull gas out too fast, then the acetone vapors can 'water down' your gas, making for a colder flame.
Hi is there a specific operating temperature that you’re supposed to be using the tanks with then I’m just asking because I live in the Midwest area and I don’t know if sudden changes in weather temperature or humidity will damage or where out the tanks much faster or the regulators and hoses it’s going to be use for automotive purposes so there’s gonna be no welding just gonna be pretty much just heating metal?
How about if you light up the acetylene and you adjust it then the light just come back to the torch and gone, what should do? Thanks. Great video KenTraining
How long does the gases last in those small tanks? Looking to get my first O/A setup and not sure whether to get small or large tanks. It won't be used everyday.....
Uh... you may want to clarify the thread type of your tanks rather than assume it's just "one-size-fits-all". My acetylene regulator/tank/hose/flashback arrestors/check valves/torches are ALL LH thread. Specifically, the tank is CGA-510
I see a lot of positive comments. I will agree that there are a few good pointers. However, having working in a small confined space with lots of combustible material is an accident ready to happen no less having poor ventilation. So you choose your two pressures because that is what you see people set theirs at? Base your settings on the type of welding you are about to complete along with the material being used and the thickness. NO brass fitting should be as tight as you demonstrated! Just snug is all. Should have known which connections were left handed threads and right handed threads before beginning the video. I have a lot more to say -..... but I will leave it with that. Be Safe!!!!!
I'm curious about what else you have to say! I'm new to oxygen and acetylene heating and welding so in my opinion the more information the better. Thanks for your comments.
thanks for the video I learned alot. have a question though. should I use Teflon tape or thread compound on all the threads to help with no leaks. makes me nervous.
Rob Kelley you should never use ANY thread tape or glues on connections from what I've learned out of textbooks. It makes sense that if a malfunction were to occur it would increase the likelihood of an explosion or burst. I'm no expert, just a beginner. so if anyone wants to chime in feel free.
Acetylene tanks should be upright for at least 24 hours to stabilize acetylene before use. Acetylene tanks are honey combed matting and chemicals to help stabilize the acetylene.
Acetylene connections may be right hand thread if of a different size to prevent connection to oxygen. All same size acetylene connections such as hoses must be left hand thread and marked with notches.
My teacher made the oxy-acetylene tanks make a LOUD noise one time to show us how not to do it. I can't remember what was the lesson though as I was so freaked out my the noise. Do you know??
Was it a big pop? if so, he probably taught you guys how not to shut off the valves on your torch. I believe if you shut the oxygen before the acetylene it will make a big pop and can be dangerous at times ( at least that's what my instructor told us)
Would rather do it in a well vented room. Shooting out the Acetylene and oxygen seems dangerous for the spot your in. But you;re a professional, so I'll shut up. :D Also much safer to do A before O when shutting off the torch.
idk about 7psi 15psi on torch i was always told 5psi 10 psi. when dose the appliction call for a 7 -10 mix ? heavier gauge steel or for stainless high carbon steels? i only realy work w 10-50 to 10-90 steel so im kinda woundering?
+KenTraining, hello I want to welding a car radiator support using ace & oxy with bronce the flame that you show here can work well for that metal? Thanks
KenTraining right on I just bought the same setup and went through my gas in a few hours to a day. Wasn't sure if there was a leak somewhere or those small tanks just don't last long

im from Australia, are the bottles similar and suitable for Size C bottles? Thanks to advise
I don't know what size C is. my bottles are 10 Cu Ft MC Acetylene Steel and 20 Cu Ft Steel Oxygen Cylinder Set DOT Approved
Thank you so much you explained beautifully..
i have a smith torch but it does not melt silver fully to pour into a mold fully why?? Do i need a better torch or borax or lubricant.
thanks for the video I learned alot. have a question though. should I use Teflon tape or thread compound on all the threads to help with no leaks. makes me nervous.
I believe either is fine.
Which fittings should I use Teflon on?
This is my first ever oxy setup
all of em
Rob Kelley you should never use ANY thread tape or glues on connections from what I've learned out of textbooks. It makes sense that if a malfunction were to occur it would increase the likelihood of an explosion or burst. I'm no expert, just a beginner. so if anyone wants to chime in feel free.
Thank u home depot near my house I will look at thank u
My little sister just got a set of those very tanks from her divorce Barbie line of toys.
:)
what pressure should it set the gauges for cutting thick metals?
And youre to turn off acetylene first because you could have a flashback if you turn it off last

acetylene should be turned off first to prevent flashback
Acetylene tanks should be upright for at least 24 hours to stabilize acetylene before use. Acetylene tanks are honey combed matting and chemicals to help stabilize the acetylene.
Pipe dope, PTFE tape (Teflon), oil, grease, ect should never be used on acetylene connections. Brass on brass clean threads only, torque 15-20 lb.
Acetylene connections may be right hand thread if of a different size to prevent connection to oxygen. All same size acetylene connections such as hoses must be left hand thread and marked with notches.
dangerous video for beginners
My teacher made the oxy-acetylene tanks make a LOUD noise one time to show us how not to do it. I can't remember what was the lesson though as I was so freaked out my the noise. Do you know??
Was it a big pop? if so, he probably taught you guys how not to shut off the valves on your torch. I believe if you shut the oxygen before the acetylene it will make a big pop and can be dangerous at times ( at least that's what my instructor told us)
Would rather do it in a well vented room. Shooting out the Acetylene and oxygen seems dangerous for the spot your in. But you;re a professional, so I'll shut up. :D
Also much safer to do A before O when shutting off the torch.
Ultimatum.Can u purge somewhere else along the set up!!
Yo, let me ask..how many minutes of cut time will a tank set of that size give you?
I never timed it but very good for HVAC work. I also keep a back up tank on hand.
thanks a lot to teacher Ken
what Flame Gas source need for cnc plasma cutter
What happens if you cut off the acetylene first and than the oxygen?
Los Ojos De HotSpanish pop
idk about 7psi 15psi on torch i was always told 5psi 10 psi. when dose the appliction call for a 7 -10 mix ? heavier gauge steel or for stainless high carbon steels? i only realy work w 10-50 to 10-90 steel so im kinda woundering?
mash7137 I don't know but lets see if another UA-camr can provide the answer.

so didactic congratulations !!!!!
Thank you for your video which brand of touch need to buy and where I can found it,,?
+Amee Hassa Mine is an inexpensive kind from the Home Depot.
+KenTraining, hello I want to welding a car radiator support using ace & oxy with bronce the flame that you show here can work well for that metal? Thanks
KenTraining i doubt they have any home depots in durka durkastan. Probably a lot of targets though.
Is that a medium duty torch set?
I am not sure of the duty rating. I believe it cost $300 or so.
Roughly how long do you get from that pair of tanks?
I don't do a lot of brazing so they last me months. BUT I always have a spare tank of each gas.
15 or 20 minutes if you're using the Cutting Torch.
@@94SexyStang Which acetylene cylinder is that? Is it the Original, the Plus or the Ulyta?
@@marynollaig4124 That was an MC tank. 10 cubic foot capacity.
Al Bundy ? :) Great vid btw
How much use do you get from those little tanks?
enough for my use. I also have a back up tank of each gas.
KenTraining right on I just bought the same setup and went through my gas in a few hours to a day. Wasn't sure if there was a leak somewhere or those small tanks just don't last long
How to set the pressure of oxy- propane regulators ?
