Acetylene torch basics

The reason the heating tip is whistling and warming up at the mixer is because you are STARVING THE FLAME. If the rig is in good conditions, starving is due to acetylene pressure being too low. There are o rings in many mixers so you don't want a backburn at the mixer.

Some extra things to know:
-Check the regulator max pressure against the tank it's going on.
-Make sure the cutting tip is sized such that you don't exceed 1/7th of the volume of your acetylene tank in an hour or moderate your use such that it doesn't happen as this can cause the acetylene to behave similarily to when it is above 15 psi.
-make sure your acetylene tank remained upright for 24 hours prior to and during use.
-Always purge your lines and regulators before opening the main valve and when opening the main valve especially with the oxygen do so slowly to prevent compression in the regulator causing an explosion.
-if you don't already have, get a flashback arrestor at both the torch end and regulator end of your setup.
-keep the tanks chained up.

Can someone answer one question that i have why is the oxygen cylinder green and not blue as per international standard?

Thank you for the video. Just got a set up today at a yard sale and looking forward to using it. 🤘

And please beginners buy flash back arresters

These are great videos brother. Keep up the great work

Thank you very much Paul from Woodward Oklahoma

What # of lense should you be using while cutting? 10 or darker?!

Cleaning tips? What to do with a popping torch?

Using a pice of wood to drag clean your tip?

What number and size of tips are used for what purposes?

Thanks for sharing your videos.

👍👍🎯

Keep acetylene bottles vertical at all times.

Good video, but I wouldn’t be cutting over top the hoses. They might last longer!! Lol

great vid. thanks ...just starting.

Most torches use propane now. Do something on those

Great video. Gonna try some cutting tomorrow

Great content it was very helpful 😊

Very good job sir!

I know this is an older video .... but great job! Well done!

Nice simple and to the point from someone who knows what your doing, thanks.

Great video. Very helpful!

Well, my boss uses this video as an intro to using the oxy-acetylene torch, so I trust it.

Unfortunately, with ALL this great instruction, his valve disengagement was 100% wrong. ALWAYS shut off Oxygen FIRST due to suit blowback potential back inside the tip/chamber. "The safe and correct method is to shut off the Oxygen first."

Will acetylene by itself burn cleanly?

Good show

Settings for heating and bending 1" x 4" bar on my mower.

Thank you sir. Very helpful.

Great video but next time just cut over the hoses

Thank you. Not many people or places will teach you this for only a like out and share. I’ll come back to freshen up on my basics with this video. Great video and teacher.

At least i have gotten something 😋

👍🏼🍻

Thanks, very helpful

thanks , ery helpful

Acetylene tank caught fire at local shop, workers dragged it outside, burned all day, all safe. Then farmer propane tank caught fire, fire men hosed water, tank burst, 4 people dead.

Well after watching this I was able to use a torch on my own for the first time to do what I needed to do and managed to not blow myself up. So I consider it a success.

I've always turned the gas off first then the oxygen on my cutting torch is that wrong do I need to turn it off the way you said let me no and thanks

Thank you

This was great! Thanks for the tips!

Helpful. I work straight with my father's mechanic shop and sometimes we have no choice to use the torch for some stuff so this helps me learn a bit quicker.

Everyone said it’s you cut the oxygen first then acetylene

Thank you.

I use to work with a mechanic who always shut off acetylene first and would hear the torch pop drove me nuts he needs to watch this video honestly

very helpful for a do it urself guy like me. thank you

Quick tip: always, always, always make sure your sparks are hitting your gas hose. It helps ensure a quick and almost painless death.

Excellent presentation; thank you..!!

Thanks man !

It has been years since I have had to use a cutting torch. You brought back all I learned in welding school. Best video I have seen on the subject. Thank you

Awesome vid. Relaxing at the rear end of the truck after teaching. Just need a beer and a cigar!

Those are some great stickers!!i love international/farmalls

Got a ? 4 u why my torch pops with a new tip? I just replaced the tip and it just pops like crazy
