Acetylene is a colorless and tasteless gas with a garlic-like odor. It also the hottest and most efficient of all fuel gases, providing high levels of productivity due to effective, localized heating with a minimum of thermal waste. Acetylene is primarily used for Oxy-Fuel cutting and welding.
Features
- A colorless, flammable gas, with a garlic-like odor, that is dissolved in acetone
- The only fuel gas hot enough to weld steel
- Used for gas welding, cutting, flame heating, flame gouging, flame straightening and flame cleaning
- More efficient, save time and money by switching to acetylene
- Slightly lighter than air and will collect at ceiling level
- High cutting speed and fast cut initiation time due to its unique properties
- Reduced Oxygen use
