Torch settings?

[seankanary]

Hey guys, I recently purchased an oxy/acet setup on craigslist and it came with a Meco aviator jet torch/tips ($150 - SCORE!) I'm curious as to what regulator settings you would suggest. I am having a hard time finding any info online. From what little info I have found, it seems that people suggest running my oxy at 7-10 and my acet around 3-5. Does that sound right?

For me , 5&5 all day long.

Thanks G, the guys I bought it from ran it at 10 for gas and 25 for the o2..Just seems a bit high.

The Meco Aviator is an equal pressure torch. Simply that means whatever pressure you run on the fuel side you run on the oxy side. The only reason to run higher oxy pressures if for flame cutting, something framebuilders rarely if ever do.

4 and 4 or 5 and 5 will work very well as Steve pointed out. Technically you can run down around 2 or 3 depending on tip size but it is hard for most regulators to run that low so we just make it easy on ourselves. I replace the oxy gauge with a lower reading one 0-20psi that helps me to accurately set that one.

Thanks for the info David.

Hey there,

Where did you find the regulator? Im have trouble with my singles holding a constant reading. So doubles are in order. Like the idea of the gauge you found!

Cheers.

Hello everyone, this is my first post but putting it in here since it is related. I am starting my first build and plan on documenting it in a separate thread.

I have kit with a Smith AW1A torch with LT103, LT104, LT106 tips. Is the 04 the proper tip? Should pressure be 5/5 as well?
