The hottest, most versatile and most efficient of all fuel gases, acetylene is often used in combination with oxygen for welding, brazing, cutting and soldering.


Due to its low ignition energy, acetylene is easy to ignite in oxygen or air. Oxygen and acetylene combined produce the hottest flame of any welding gas mixture.


Ideal for

  • Oxy-acetylene cutting
  • Welding
  • Flame heating
  • Flame hardening
  • Flame straightening
  • Flame cleaning
