Please read my "Welding Safety Details" page for cutting torch safety via the Welding Safety button at left, or by way of this link:
Watching a fellow worker cut through a railroad railing with a torch really got me hooked on the cutting torch & arc welding. I still have that chunk of rail & use it as an anvil from time to time.
The first thing I want to do is show you the type of equipment you need to use for your safety, & to help you to do a good job.
Keep the connections real snug but not over-tight. Clean up the thing once in awhile, that includes ME.
Check to see that all the holes in the tip end are allowing full flow. If not, shut it off & clean the tips.
To shut the torch off, close the "gas" valve on the torch handle, then the O2 valve.
Then I usually crack the high pressure valve (on the handle) to blow out any gas left.
Now you can have full use of your torch, & see "what it can do". You can cut MANY sizes & shapes of material:

Remember that when you're cutting with a torch, there can be a fantastic amount of sparks going everywhere!!
Please be careful & watch out for the other guy as well as yourself!
