- Oxy-Acetylene Torch Setup- Connection, Leak Test, Regulator PSI Setting, Flame Adjustment, Shutdown. I show how to Adjust the Pressure to get a Reducing Flame instead of an Oxidizing or Neutral Flame for Brazing Copper Tubing. Supervision is needed by a licensed HVACR Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety. Flashback arrestors can be added to the base of the handle where the hoses connect and at the tank regulators.

Nice informative video. I believe oxygen cylinders are seat to seat valves and should be opened all the way, otherwise they can leak around the stem packing (2000 psi is a lot of pressure). For additional safety leave the wrench on the acetylene bottle you don't want to go looking for that during an emergency.
Thanks! I just wanted to thank you for all your video they’re very professional skills and educational
Thanks so much for that nice illustration Mr.Craig.
You always put out great video's. I enjoy everyone of them and learn a lot too. Thanks.
Thanks Drifter436!
Very good safety oriented vid Craig ... I know the young'ens appreciate what you do ...
Thanks Eddy!
I absolutely agree 💯, I am currently going to school for HVAC btw.
Very Useful & Educational Video as Usual !
Thanks For Sharing & Posting
Thanks Thomas!
I really love your video man! It really helped me to set up my oxy acetylene equipment since iam a beginner, by the way I just subscribed.
Thank you so much! I bought one almost a year ago, but for any reason, or maybe I was a little bit scary to use it. Now after your video I've got the information that I can trust. Now, I'm absolutely sure what to do with my tools and how to check it first be sure it's safe. Please film in the next. Videos how to weld reversing valve properly. Some welding tips. Thank you, Craig!)
Thanks for letting me know what you would like to see Tapch. I would have to wait until I had a replacement to film something like that, thanks!
AC Service Tech LLC thank you, will wait)
Well done video.
great explanation
Thanks Gill!
Very nice explanation 👌
Great i was looking for this video now that i just bought my new bracing torch kit
Glad to help Luis!
Good info for safety.
👌👍👍👍
Imagine dragging in buckets n a fire extinguisher wrenches torch and all ur hand tools to the attic where the e coli is and ur boss wants you to go to another job
thanks, partner for sharing!!!!
Thanks Jimbola77!
Thanks 4 the video great 2 c u back
Thanks Jonathan!
Hi.. happy new year .
Brilliant video
Cheers
Glad you enjoyed it
Thanks for sharing. Never hurts to reming yourself how to do it the right way :)
Thanks Alex!
Craig, how about a video on Oxy Acetylene vs Air Acetylene? Pros and cons of both and which you prefer to use most often. Thanks for all the great videos.
Thanks for letting me know what you would like to see!
Excelente
Do you use/recommend flashback arrestors on your torch setup?
Great professional vid! Whats the reason for the red hose reverse thread?? Only thing I can think of is so the hoses won't twist?
Tq borther
and one to check list,check the packing nut on acetylene tight and bubble test,, my was loose
Hey what's the working hours on a setup like that. Well explained video thanks
Thanks for the reminder to check the acetylene packing nut.
Yeah they come ready to leak sometimes once open, thanks
Need some advice please. I found regulator gauge sets on amazon for light duty use, but it says it fits all acetylene tanks EXCEPT FOR MC AND B TANKS and I wanted to use tanks the same size as this video (MC acetylene tank). Could I use adapters or is there a regulator set I can use with these MC tanks and the small oxygen tank in this video? Thanks for all the great videos and the help.
Great job as always! I don't normally see most of the guys use the eye shield. Is that shield used because the bright light from the flame can cause damage to the eye or just used to protect against the obvious damage the heat from the flame can cause in an accident?
Damage to the eye, thanks Mr. Roberts!
Are the 5/10 psi pressures the same for brazing in plumbing?
Can we use fuel gases for swaging or flaring of dishends
What type of grease can I use to lubricate the knobs on the torch handle? I have a Victor torch handle and they are hard to turn off and on.
Correct me if I am wrong but I can't see flashback arrestors fitted on both ends!! Is this normal practice or do we have safety issues here?
Congratulations!
I just bought this kit and I got the bottles refilled.
My question is how long do the bottle contents last?
I started using the torch today and I tested my cutting attachment which was maximum 5 mins
and I did some welding which was around 15 mins total.
now my Acetylene was at 200 psi and now it's less than 100, What's going on?
How long do the tanks last when you use them?
These tanks are meant for remote use when you can’t get a big rig , if you got an Mc rig thats like 10 cubic feet, and by what you described that sounds normal, so quick repairs I would suggest and it’s more suited for a lower oxygen flame for brazing , cutting with an Mc/10cf rig you’ll be blowing through oxy like crazy
Where is the flashback arrestors or check valves. I have similar torch and bottles and very confuse about flashback arrestors installation. I bought Flashback Arrestor Set. Inline, 1/4 inch Barbs and I'm in the way to cut the hoses and install arrestors. Flashback arrestors is not available for 3/8-24 A hoses. I like to see some body to cut hoses and install arrestors and what clamps can be used.
Excellent explanation.
One question. Why don’t they have a handle on acytline tank similar to oxygen tank? That would be more easier in emergency
They actually are in the process of changing them over to the easier to shut off handle now but there is a lot of old tanks out there, thanks!
tested for leaks before you opened tanks, I also have check valves on hose to torch connectors flashback arrestors
Yes we always put the bubble leak detector on and then turn the gas on. The detector won't go anywhere and this way right when you open the tank up, you can check for leaks, thanks and yes arrestors can be added as well. Thanks Dennis!
@@acservicetechchannel good to know,, I need that type leak dect.. thanks
Hey Dennis, I have that leak detector linked on the 12th line down at- www.amazon.com/shop/acservicetech -thanks
How many oxygen pressure ?
Great video of safety points! Your ABC rated fire extinguisher would suit your purposes better if it had a hose on the end just in case you had a fire through a wall penetration. It shouldn't happen but mistakes do happen....
Hey the more additions to the safety gear the better, thanks Jonathan R!
@@acservicetechchannel It's not something you realize you need until you have a new helper find d out he didn't have enough thermal paste/wet rags and something is burning behind the brick wall.
Not a good time to find out your fire extinguisher is pretty much useless.
Can you make a video for oxy propane torch?
Are there any mini brazing torch for DIY Jobs
Is the #2 tip the best all around tip you like to use? Thanks.
It is the tip that is most normally used unless you are talking large tubing for big commercial applications, thanks Danny!
No check valves or flashback arrestors?
For lighting I turn on acet. and then oxygen. Turning off I turn off oxygen and then acet.
There are forum where people preach every way possible. I don't think it matters, but turning off acet. first can sometimes cause a pop sound when the flame goes out that can make newbies jump. Lol
I agree there are many ways. Turning the oxygen up and turning the off acetylene off first is what stops the popping sound without making any bad black soot in the air, thanks kneeman7!
The pop sound is the flame going completely out, it is reaching the perfect burning mixture and causing the pop. This pop is a handy cleaning aid blowing out any little sparks that may have lodged in the blowpipe and carbon as well.
Nice tip Mentorcase!
How do you clean handle and tips for regular maintenance
You only hand tighten the tip. Using a wrench will crush the o rings and lead to premature failure.
I do 5/20 on a 3. Is that ok? It works for me, but I will try the 5/10
You can, you likely don't open the oxygen handle as much though but whatever you are comfortable with and can attain the right flame with, thanks Electric Boogie!
👍
Uniweld video said you can just hand tight the tip. Doesn't seem right to me. I'd just tighten it with a wrench but not too tight.
No flashback arrestors?
Certainly you can add them as well, thanks
What are your thoughts on a Turbo Torch set up?
Air acetylene will work just fine! I use those as well, thanks!
The A-11 tip is the one I use the most, thanks
#Innovation
Ha ha, thanks Bedrock Affect!
Good call on the water.. water and molten metal is a lot of fun!!
I'm being a smart a$$ sand for safety water explodes hot metal..I work in a brass foundry.
I take it you don't braze 1-1/8" and larger by the way you're explaining
What about your hazmat gear? LOL just kidding. Any guy working for someone else had better follow basic safety! My buddy brazes with no eye protection, no gloves, no fire extinguisher and this 30 year AC vet wont be told otherwise... weird he doesn't even wear reading glasses.
I always ask that techs where all the safety gear when brazing copper tube, thanks
open the tank valves all the way, they were designed to work that way.
Hey David, the manufacturers and distributors all recommend to only crack the acetylene tank which is fine for the output to the reg, thanks!
Should not open acetylene tank valve more than 1/2 turn. Not needed.
You absolutely must open the oxygen tank valve all the way to back seat otherwise you could lose the contents of the tank it will leak. Just crack the acetylene tank valve is fine.
OMG Bubble boy
wtf
You don't want fire erupting from a loose hose. Seen it, its not fun!
Very good but the fire is too long it's going to burn other stuff
