DENSITY: The use of liquid fuels such as gasoline and diesel provide a flame with FOUR times the density of fuels like Acetylene or Propane thereby providing a significantly increased burn time over greater distance than the flame a compressed gas can. The longer burn time over a greater distance (for both the primary and secondary flame) results in a much greater preheat flame distance allowing operators more flexibility and greater coupling distances. The high density flame easily bridges air gaps cutting thru and across voids.

OXIDATION: When cutting steel, it is the steel itself which acts as the primary fuel source. The preheat flame is simply the catalyst to initiate combustion. A higher level of oxidation means more of the steel burns and is converted into BTUs. DAVCO systems oxidize 99.9% of the steel thereby unlocking more energy to sustain difficult cuts. Acetylene oxidizes 70% of the steel wasting 30% of the available energy and leaving a puddle of molten steel.

FLAME TEMPERATURE: The high density high flame temperature of the Liquid Fuel Torch allows operators to maintain ignition on steel that is painted, rusty and wet with greater ease than torches that use compressed gases.

SPEED:  A unique feature of a liquid fuel torch is the huge volume expansion of liquid fuel as it evaporates into a gas as it exits the torch tip.  This creates a flame velocity up to 10 times greater than torches that just use compressed gases.  (which rely on regulator gas pressure for flame speed).  This very high velocity flame improves cutting function which combined with almost 100% oxidation gives an exceptionally clean, smooth and fast cut.


The combination of these factors that make the performance of the DAVCO SupaCut liquid fuel torches significantly more powerful than any compressed gas oxy-fuel cutting technology while also giving increased  thruput and minimal subsequent reworking or refinishing of cut material.
