Oxy acetylene help need some tips?

[jjmarquez84]

I never used oxy acetylene before I'm unsure on what my pressures should be when I hook up my regulators for oxy and acetylene. What pressures should my oxy and acetylene be at? Any thoughts?

[Makinhole]

Depends upon your tip size and what task you are performing. You should consult your manufacturers literature to find the correct pressures.

[timebuilder]

Your cut set literature will have the basic pressures you need.

Nice thanks guys.

Read the manual.


I find that most guys run pressures way too high.

Assuming (big leap) that you're using the typical small oxygen acetylene setup, 5 and 5 are good starting points.

[Six]

Acetylen 5 and Oxy 15.

Been setting them up that way for years.

Does he know how many turns to open acetylene tank?

[hurtinhvac]

7 A, 11 O and adjust from there at the torch valves. Nice strong hiss, 3/4" blue flame for suction line, 1/2 for liquid line.

Keep the service wrench on the acetylene tank and poised to close in a hurry.

Works for me - however I have no idea what my tip size is...just the one I inherited and got used to.

I'm betting once you get used to it...you won't be paying all that much attention to pressures. Until your tanks run out.

Also a great tip,

open tank quarter turn past when you see the primary pressure gauge read pressure.

Check out this guy on YouTube. He has a lot of great videos on brazing that are made well.
