IMPORTANT!! Be sure to open the oxygen cylinder valve S-L-O-W-L-Y so you don't get a Regulator Burn Out (RBO). There's something called the heat of compression, and if you have a bit of oil or grease or oxygen in the high pressure side of the regulator, and you blast oxygen into it, it might ignite.
Hey great vid man! I have an oxy-acetylene welding kit at home that i haven't gotten to use yet (mainly because i didn't know how), but your instructions are really gonna help me get a metaphorical foot in the door. Any extra safety tips you'd care to pass on that might keep me alive?
if ur a noob and it comes time to assemble the oxygen and acetylene tanks and puttin those gauges on if you put the wrong gauge on the wrong tank ull know u did fucked up once u turn those tanks on a first year in my welding class did that put the acetylene gauge on the oxygen tank which holds about 4000psi and i shit u not he jumped so fuckin high and bolted out of there haha great times. but seriously dont fuck up when assemblin the torch tanks
@CWSuzukiRider167 You can't hook them up to the wrong tanks. the threads (screwy parts) that hook up to the tanks go in opposite directions and are different so you can't hook the wrong one.
@freddytk421 Not only that, but the acetylene regulator (at least, the ones we have) have 15 working psi as the midpoint/red zone, the oxygen regulator has far greater amounts on it.
How do you dismantle Oxy-fuel bottle set, I know first you have to shut off valves on both bottles, spin out the regulators all to 0 then im stuck after that...
@Eyelanderules just close the top valve, the one that is on the bottle, then let all the gas out of the torch hoses. you can just take the regulator off.
I Freddy, great video but I noticed one problem with the way you open the acetylene tank without the regulator on it. You should never open an acetylene tank without the regulator because acetylene can explode if released at higher than 15psi, and without the regulator there's no way to know how quickly the gas is coming out. That is why acetylene regulators only go up to 15 psi max. That being said, it is a good idea to open an oxygen bottle before you put on the regulator to remove debris.
The white teflon tape you used in the vid might not be the best way to go. They make a similar tape yellow in color just for gas. It cost more and it's a little thicker and made just for gas applications. I used it when i make a washer and dryer hook up in my apartment years ago. Worked out great for the next 6 years till I moved. I am a new bee with the torch. Might get a mig welder instead just not sure what way to go yet. Gas welds are not as strong as mig welds from what I've read.
I'm an experienced welder and torch man. The only flaw I saw on your video is how the regulators are mounted. The faces of the gages should be faced in an upward position . If you had a faulty gage you would want it to blow upward and not at you. Other than that great job that was not a perfect weld it was a SEXY weld LOL.
One suggestion I have is to open the oxygen valve SLOWLY, to avoid putting a sudden force on the internals. I have heard this can lead to premature failure or explosion of the regulator.
@66suhaimi You can tell if it's leaking on the regulator. turn off the tank and if the pointer goes down then it's leaking. foaming spray is used to locate the leak but you don't have to spray everything every time you hook it up.
regulator only has the gas constant not lowers the pressuer and you only open the fuel gas until it registers in the reugulator, oxygen working pressure is 40 and acetylene gas is 3-5, and tint is 3-9 on cutting with oxy-fuel
You should add in how to beed weld. because if they are beginners they wont know how to. make a not about doing circles or "u"s witch ever you prefer. also not that if they are beginners, to beed weld the psi should be at acetylene at 5 PSI and Oxygen at 20 PSI. i just started welding and those were some tips that my instructor used. Im only 14 but i watched your video and decided to make a note.
from the way i learned your supposed to open the oxygen all the way because its so high pressure that if you dont the valve will leak very slowly which isnt damaging its just a waste and youll go through oxygen much slower if you open it all the way because it seats the valve tightly and stops the oxygen from escaping
@KrazyJak90 Oxygen makes things burn more intensely and cleaner... anyone that blows themselves off with oxygen in an enviroment with flames is not very competant at all. I don't mean to sound like a "know-it-all", but I've heard of someone actually dieing from praticing that clean-off "procedure". :(
Good video dude, You are entertaining as well as a good teacher. Given a choice, I would rather learn from you about welding than some college teacher, you have that personal touch that so many teachers lack. Thanks for putting this video on.
can never go wrong with a 1/4 - 1/2 turn to open acetylene. what helps adjusting your line pressure is opening the lines one at a time and then adjust your pressure. if you use the 40 - 5 mix ratio acetylene will jump to 7 and oxy will about 43-45. and tints you can use anywhere from a 3 - 8. 5 is usually on the money not to dark and not light. as for leaks its ok to use a wrench to tighten up the lines and regulators. good vid as well
@buckyboy2000 all the information hes giving is safer then the standards except he goofed on the tape for the oxy tank but the acetylene is safe untl 7 psi and the oxygen is good until 40 those are the limits ive been taught maybe you could push them and get away with it but i dont recommend it so 5 and 10 hes working in plenty safe conditons the only thing you could do to screw up is a gas leak which hopefully if people listen to him wont happen
Freddy 16 gauge means that if you stacked 16 plates of metal on top of each other they would equal 1 inch. It's more or less a sheetmetal thickness deal. Thanks for your T Tubes
So, when your speaking of gauge, then it just means that the gauge is a fraction and the denominator number is the thickness required to equal an inch. right? In your case, 16 gauge would mean that 1/16 would equal a gauge.
_the shade googles/face shield you will need will depend on the plate thickness and what operation if gas welding it is as follows: Less than 1/8'' -4 or 5 for 1/8" to 1/2"- 5or 6 for over 1/2" 6 or 8. For cutting its all lower.
_16 gauge steel is the equivalent of 1/16 of an inch or the decimal equivalent of .0625 and you will want to match the filler to about the base metal thickness
I just started a welding class & find your videos very helpfull. Most important...turn the fuel on 1st & shut the fuel 1st...red hose. Hope you do some more updated ones, thanks!
I hate this video :) you can see the nerd helmet on my video called ep3. demon bending. ITs just a face shield with a #5 lens. I made this with an old VHS camera because my camera stopped working and I had just gotten the youtube bug. thanks for watching.
you showd only open the oxy green or blake with whit one turn thats the same with aseterlen dark red..................and the hose can by blure and red and the shad shoud be shade 9 or 6
yes the pressure should be 40 oxygen and 8 acetylene for a #2. And no you cant fill a acetylene tank with hydrogen, Acetylen bottles have other junk in them to keep the gas stable. Hydrogen molecules are tiny so they may leak from regulators not for them I'm guessing? I don't really know about hydrogen but I am pretty sure you need specific everything for that and it's not a common fuel for welding because its so dangerous to store tansport and use.
You are exactly right. Acetylene tanks have acetone in an absorber to keep the acetylene stable. And every gas bottle requires a different regulator. They each have a specific color, and different threads, left hand, right hand, sizes, etc to prevent misuse. Hydrogen does in fact sneak through many materials, but not a thick steel bottle that it is distributed in.
Yes, I got my welding setup on craigslist also. The guy gave me a 3 minute tutorial which was enough for me to repair the crack in my shovel. (I'm so proud of my shovel - I show everyone!)
I used flux and you did not. Why no flux? I used mine "because it was there". Worked nicely!
video is good, your weld on 16 gage was excellant wish you provide me with tips on how to do it and what kinda rod did you use, and how you choose wich size for what thinkness
I have another video that goes more into detail about that stuff. there are charts on the internet that tell what pressure and tips to use for different thicknesses.
on the acetylene tank, u can just turn it 1/2 or 3/4 turn and your good, oh u can put 40 psi on the oxy tank. sun glasses is realy not a good thing. oh if i may say, that was a bad ass weld.
There can be 2200 psi coming out which can BLOW OUT your gauges....also, don't stand in front of those potentially exploding gauges as you open the valve..
it does get expensive but it's better for some things I do with thin sheet and 1/4" rods than electric welding because I can heat and bend with the fire and then weld.
I'm a female weld in school 30 yrs. ago and now going back to welding school. I like what I just saw bring back memories. I weld for 3 years in high school. My instruction Mr. Berell Williams beg me to go to college because I was a pro in it. I want to say thanks for Mr. Berell because he taught me well. And you done a good job too.
If you turn on the oxygen so that it can be barely heard at the tip, then turn on the acetylene a bit higher than you did, when you light it, the black soot or raw carbon particles (present in acetylene only) will not float off the torch and make a nasty black mess as they land all over your shop.
Those bits of soot get into everything!
If your beautiful blond girlfriend gets it in her hair, she will quickly become a brunette looking for a new boyfriend...
I am not a welder by trade but am fairly familiar. Looks like you got it right (somebody correct me if I'm wrong) but I would like to see the back side of the weld in order to illustrate the
penetration through the metal and how it should normally look on thin to moderate gage metal.
I have made some better videos since this one where you can see the actual puddle and molten filler, please check them out. I will show the backs in all future videos thanks for the advice I never even thought of that.
I just bought a welding/cutting torch setup, including full tanks, from some dude on Craigslist. On the way home, I asked myself "Now what? Where do I start?" Your video gave me a good primer and helped me to not accidentally kill myself. Thanks!!!
your welcome. also be sure to secure the tanks with a chain or strap before taking off the caps to something stable, don't use any oil or wd-40 anywhere even if something is stuck because it may explode when the oxygen hits it. make sure the acetyle tank is upright for at least as long as it was lying on its side if at all preferably for a day. Don't transport the tanks with the regulators attached and without the caps on.
Sometimes a frank, plain english, lesson is better than a bunch of high falootin' techie terms! Nice vid Freddy! I learned a lot from this vid and the comments that followed.
thanks, check out my video entitled "hobby art welding cheap ep.1 torch" and tell me what you think. it's really not for art just a basic welding video.
hey you pretty much nailed this video i just wanted to mention that when your oxyfuel welding you want a 1:1 ratio of oxygen and acetylene and should be used at 8 psi for both oxygen and acetylene
ok so I read the book and the psi depends on the tips you use and should be adjusted as needed. for example for a 000 tip the min psi for both is 3 and the max is 5 and for a #6 the min oxygen pressure is 7 and the max is 16 and the 1:1 ratio is true up a #3 size tip then changes.
This comment has received too many negative votesshow
Are you trying to blow yourself up with opening an acetylene tank with no regulator attached? Acetylene is extremely flammable above 15 PSIG and can ignite at that point!
What I should have said is "Momentairly open and close the cyclinder valve (commonly reddered to as "cracking") This dislodges any loose contaminents that may be present" like it says in the instruction manual. sorry
You need to crack the tank when you first get it in case there is any dust or dirt in the valve. what are you talking about. you just need to be outside it won't spontaneously combust I have done it thousands of times.
if you hold the torch at the same angle you would a mig you get a better weld and you turn the air on first not the other way round beceause with no air to force the flame out the nozzle there's more chance that the flame will flow back in the pipes and into the bottles i'v never seen it in real life but i bet thats would be scary
Great delivery, beautiful weld. One thing to add about the oxygen regulator setup - If it's leaking that means it's not tight enough. The part that seals is the brass part and it has to be nice and snug. Teflon tape can get into the regulator and mess things up. Teflon tape is for tapered threads like NPT where the threads actually do the sealing. Also, the oxygen tank valve doesn't necessarily need to be opened all the way. It should be alright on a good tank. It's personal preference.
Your O2 fitting is a bit different from mine and I'm not 100% sure, but for sure you should avoid the teflon tape. It will shred and make little pieces that are very hard to get out of a regulator. On mine, the fitting is a right hand thread POL. On yours, I think either there is supposed to be some type of O ring or nylon gasket, or maybe the brass does provide the seal like on mine if the fitting is tight enough. I might have to go out to the garage and look at some of my other regulators
because I think I might have one like yours and maybe figure out how it's supposed to seal. The teflon is okay as a temporary fix as long as you're comfortable with possibly having to disassemble your regulator to clean it out of there, but it's not really going to fix the leak on that kind of thread at such high pressures.
a little tip you dont use sealant on regulaters beceause they seal themself's and if it leaks when it's really tightened up get a new one beceause it'd fucked.
is the weld strong?

open the oxy cylinder sloooowly at first.
There can be 2200 psi coming out which can BLOW OUT your gauges....also, don't stand in front of those potentially exploding gauges as you open the valve..
Good vid Freddy.

it does get expensive but it's better for some things I do with thin sheet and 1/4" rods than electric welding because I can heat and bend with the fire and then weld.

I'm a female weld in school 30 yrs. ago and now going back to welding school. I like what I just saw bring back memories. I weld for 3 years in high school. My instruction Mr. Berell Williams beg me to go to college because I was a pro in it. I want to say thanks for Mr. Berell because he taught me well. And you done a good job too.

On the lighting of the torch:
If you turn on the oxygen so that it can be barely heard at the tip, then turn on the acetylene a bit higher than you did, when you light it, the black soot or raw carbon particles (present in acetylene only) will not float off the torch and make a nasty black mess as they land all over your shop.
Those bits of soot get into everything!

well your wrong because your suposed to always weld in a well ventalated area with suction vents.

I am not a welder by trade but am fairly familiar. Looks like you got it right (somebody correct me if I'm wrong) but I would like to see the back side of the weld in order to illustrate the
penetration through the metal and how it should normally look on thin to moderate gage metal.

I have made some better videos since this one where you can see the actual puddle and molten filler, please check them out. I will show the backs in all future videos thanks for the advice I never even thought of that.

I just bought a welding/cutting torch setup, including full tanks, from some dude on Craigslist. On the way home, I asked myself "Now what? Where do I start?" Your video gave me a good primer and helped me to not accidentally kill myself. Thanks!!!

your welcome. also be sure to secure the tanks with a chain or strap before taking off the caps to something stable, don't use any oil or wd-40 anywhere even if something is stuck because it may explode when the oxygen hits it. make sure the acetyle tank is upright for at least as long as it was lying on its side if at all preferably for a day. Don't transport the tanks with the regulators attached and without the caps on.

thanks, check out my video entitled "hobby art welding cheap ep.1 torch" and tell me what you think. it's really not for art just a basic welding video.

it's the same in the uk as well benn859

Does anyone know if the threads are the same over in Europe (UK)... ie oxy is normal, acetylene is reverse?

Just call your local welding supply store where you plan to buy/rent your tanks from and ask them.

Thanks, nice video. Very straight forward and not trying to get too techinal.

hey you pretty much nailed this video i just wanted to mention that when your oxyfuel welding you want a 1:1 ratio of oxygen and acetylene and should be used at 8 psi for both oxygen and acetylene
dc4allitsworth 3 years ago
ok so I read the book and the psi depends on the tips you use and should be adjusted as needed. for example for a 000 tip the min psi for both is 3 and the max is 5 and for a #6 the min oxygen pressure is 7 and the max is 16 and the 1:1 ratio is true up a #3 size tip then changes.

I found out they are called adjusting screws after I made this but I forgot to add that. but diaphragm screws sounds good. I'll add that thanks

This comment has received too many negative votes show
Are you trying to blow yourself up with opening an acetylene tank with no regulator attached? Acetylene is extremely flammable above 15 PSIG and can ignite at that point!
michael218262 3 years ago
What I should have said is "Momentairly open and close the cyclinder valve (commonly reddered to as "cracking") This dislodges any loose contaminents that may be present" like it says in the instruction manual. sorry
freddytk421 3 years ago
You need to crack the tank when you first get it in case there is any dust or dirt in the valve. what are you talking about. you just need to be outside it won't spontaneously combust I have done it thousands of times.

Great video for people wanting to learn how to set it up to get ready to weld.
Greathome2 3 years ago
if you hold the torch at the same angle you would a mig you get a better weld and you turn the air on first not the other way round beceause with no air to force the flame out the nozzle there's more chance that the flame will flow back in the pipes and into the bottles i'v never seen it in real life but i bet thats would be scary

Great delivery, beautiful weld. One thing to add about the oxygen regulator setup - If it's leaking that means it's not tight enough. The part that seals is the brass part and it has to be nice and snug. Teflon tape can get into the regulator and mess things up. Teflon tape is for tapered threads like NPT where the threads actually do the sealing. Also, the oxygen tank valve doesn't necessarily need to be opened all the way. It should be alright on a good tank. It's personal preference.
TheLightningStalker 3 years ago
So can we use tape on the 02? because thats the only way I can get it to not seep out sometimes? I never use it on the acetylene.
freddytk421 3 years ago
Your O2 fitting is a bit different from mine and I'm not 100% sure, but for sure you should avoid the teflon tape. It will shred and make little pieces that are very hard to get out of a regulator. On mine, the fitting is a right hand thread POL. On yours, I think either there is supposed to be some type of O ring or nylon gasket, or maybe the brass does provide the seal like on mine if the fitting is tight enough. I might have to go out to the garage and look at some of my other regulators
TheLightningStalker 3 years ago
because I think I might have one like yours and maybe figure out how it's supposed to seal. The teflon is okay as a temporary fix as long as you're comfortable with possibly having to disassemble your regulator to clean it out of there, but it's not really going to fix the leak on that kind of thread at such high pressures.
TheLightningStalker 3 years ago
a little tip you dont use sealant on regulaters beceause they seal themself's and if it leaks when it's really tightened up get a new one beceause it'd fucked.
jobbly1234 3 years ago
' You should clean the tip, but I don't want to' LOL
Just finished watching the whole thing. Really excellent video. And a beautiful weld too!
