Acetylene Cu. ft. per Pound of Gas 2.5 - 81.0
(or liquid) Low
Acetylene (C2H2) is a colourless, Low
highly flammable gas. Mostly used Wt. Compared to Air Low Copper &
for oxy-fuel cutting and brazing Silver Alloys
applications, acetylene has a high Liquid wt. per Gallon - lbs Low
heat release in the primary flame and Cylinder High
moderate heat in the secondary flame. Boiling Point - ºF Stable 15
Unstable
Vapor Pressure at 70 ºF - psi
