Acetylene is the hottest and most efficient of all fuel gases making it suitable for a range of applications and requires the least amount of oxygen to ensure complete combustion. Acetylene is recommended for underground working conditions as it is lighter than air and in cutting, gives the fastest preheating and piercing times of any fuel gas combination.
