Air acetylene provides similar advantages to when you use oxy / acetylene when compared to oxy / LPG.
Using air / acetylene gives you the concentrated heat that no other fuel gas can provide.
The ASQ 21 Air / Acetylene burner has a quick fit system allowing burner nozzle changing within a matter of seconds.
Acetylene consumption - 0.5 CFH at 5 PSIG
The low flow of Aceylene enables use with the smallest DA cylinders i.e. Hobbyweld "orignal" acetylene, as well as the larger HobbyWeld "Plus" or "Ultra" acetylene cylinders.
