Range of a given OxyAce tip
We know general instructions for chosing a tip, setting pressures,
lighting the torch and setting the Acetylene so that the flame is just about to leave the tip. Then we add O2 until we get a flame with just a little feather. Written instruction seems to stop there. However, we know one can adjust the torch for a larger or smaller neutral flame, so each tip has a range of useful flame sizes. At the low end the torch makes no noise; one opens the torch and you go thru a hissing sound, to the roar of a jet engine. No one seems to discuss how to determine the upper end of this range. Can someone discuss how to determine the upper range of a given tip size? - Mike |

Operating tips in their upper range can help disperse the weld, and especially brazing puddle. Sometimes this is desired, sometimes it's not. |

If you want more heat you turn up the gases. When the tip exit speed is greater than the flame speed, you're done. Brian W |

Brian W Kent White www.tinmantech.com has an excellent essay on setting up torches; start at max and adjust from there. Bob |
