11-2. Fuel Gas And Flame Characteristics

Settings: Neutral Flame

Acetylene − Oxygen

After igniting, open acety-
lene valve until soot disap-
pears from end of flame.
Add oxygen until the feather
shown on the right just dis-
appears in the bright inner
cone.

Propane − Oxygen

After igniting, add oxygen
until bright inner core reach-
es its shortest point and
then stop. Repeat process
to force as much fuel
through the tip as possible.
