Kepping the correct flame


#1

I have what is probably a simple question . I am using a
Acetylene & Oxygen Little Torch , which was bought used and have
had trouble at times keeping it lit and burning with the correct
flame .It came with a mc tank on the Acetylene and it lasts what
I believe to be an unusually short time using #3 & #5 tips with
the gauge set to 8 I just recently noticed the fine print “
almost unnoticable” that the gauge is measured in Liters per
Min. So I have been running it at 8 liters / min and not at 8
psi.So I guess the question is ,What setting in Liters / Min
should I be using for #3 & #5 tips or how does the settings
convert to psi ,local gas suppliers have no clue.The gauge shows
regulation of 0 to 15 liters / min…

Thanks again,
Timothy

You have a gauge on the regulator that is set up for medical
use. These gauges are normally used with an outlet orifice so
that the gauge can read a flow indication. You should either get
the gauge changed to a low pressure one at your welding
distributor or buy a new regulator set up for the gas you are
using. Jesse

Hello Timothy,

It sounds as if you have a regulator that is used made for
medical use or some use other than a torch. It sounds like a flow
regulator, not a pressure regulator. They are not designed the
same.

A flow regulator is designed to mantain a constant flow (volume
/ time) at any pressure. A pressure regulator is designed to
mantain a constant pressure (force / area) at any flow rate.

You would probably be better off getting a pressure regulator.
