The size of the cutting nozzle used in oxy-acetylene cutting process depends mainly on
thickness of metal to be cut
purity of oxygen
duration of cut
type of cutting blowpipe
In gas cutting, if too little cutting oxygen is supplied
the metal will be cooled down
the kerf will be narrow
the kerf will be wide
the metal will fail to cut completely
The function of the central hole in the tip of the cutting blowpipe is
Supply oxygen for preheating
Supply acetylene for preheating
Supply oxygen for cutting
Supply acetylene for cutting
