[@michaelpatrick6950]

I was a farm boy welder/torch user who became a process engineer for 40 years. I always liked getting tips from my pipe fitters on welding and cutting. As I showed respect for their knowledge and skills, they always tolerated me watching them work. This presentation of proper torch use is right up there with the best tutorials I've ever seen. Outstanding job. As someone else commented: it must be THOSE guys who gave it downrates.

[@georgereves9370]

I've probably watched an hour of other torch videos and this one was, without a doubt, the most informative. I really respect the amount of pride you place in your career and it shows because of the amount of safety items you address. It was very "Mike Rowe"esk. We should always be as safe as we can be.

[@manuelfreire4260]

If you sharpen your soap stone on both ends, don’t sharpen on the same side. Make them opposite. This way no matter how the soap stone lays flat on the table, you can pick it up easily with heavy gloves on by pressing down on one end and the other end will pop up so you can grab it.

My stepmom had a friend & she got burnt kind of bad because someone greased the tank valve covers, I knew the lady after when she was around 90 years old, her husband (when he was alive) would tell her that she rebuilt the well drilling bits so nice he would have her do them instead of himself. :) I keep telling my wife how nice she cuts the lawn & such. :) I'm trying to be safer when it comes to all my building projects, now I'm almost 60, & got lucky few times but don't want to press my luck either. Thanks for the videos it's helping my to understand why I cut so bad. I'm looking forwards to giving it a try again, (after watching the video again).

Shut the fuel off first to keep a back burn from happening inside of the torch or hose

“A” before “O” or up you go

[@kennystroner7431]

I have taken a couple welding classes and we turn the fuel on 1st. light up. turn gas up or down till you get a nice clean flame. Then turn on oxygen till you get a nice small ideal flame for welding. When shutting down you reverse this operation. Oxygen off 1st and gas off last. This man did it perfectly as I been taught on day one how to weld with a torch. I absolutely love gas welding! One of my favorites for damn sure! been taught. After you turn the gas off it doesn't hurt to check or listen to any leaks in your tips. www.harrisproductsgroup.com/en/blog/2019/may/working-with-torches.aspx

[@firstmkb]

Thank you for explaining WHY on so many things, because it's easier for me to remember how something works than a procedure without context. If you haven't been an instructor, you should consider it, because you absolutely nailed this. I expected to watch 10 minutes of mostly review when I had some downtime, and was glued to my screen to the end. I'm not a pro, but I have never seen anyone make such a clean cut with a torch. I can help on the scarfing term a bit. In woodworking, a scarf is a long shallow bevel that can be used to join wood to make longer boards. The scarf tip looks like it was meant to cut long shallow bevels also.

interesting, i didn't know that there's a vacuum effect happening at the tip, tips can be damaged pretty easily , would you agree that one should be using a dabbing motion instead of getting in there in a speedy saw maner with the tip cleaners ? good that i see you shut of the the oxy first and then acyetlene , uv/ ir is produced from oxy cutting, this is why it's important to wear shaded glasses , it may even be important to even where a full shaded face shield depending on the work being done. also good to see you back off the pressure screws and bleeding the lines, i think if you don't back of the pressure you can ruin the regulator and from time to time you'll see a regulator that doesn't display correctly .

It's all infrared being produced when cutting which is only harmful to your eyes... same with plasma cutting I believe.
