Abstract:

A consumable, oxy-carbon arc cutting electrode to be used in an oxygen exothermic torch for cutting both ferrous and non-ferrous metals. The cutting electrode includes a hollow, outer copper clad steel tube. A plurality of copper clad carbon fuel rods run through and are surrounded by the outer tube. The plurality of fuel rods are aligned in side-by-side engagement with one another and positioned circumferentially around the interior of the outer tube so that a passageway extends longitudinally through the outer tube in coaxial alignment with the circumferential arrangement of fuel rods. Pure oxygen gas is blown from the torch down the passageway through the center of the outer tube and along the fuel rods. By virtue of the foregoing, the oxy-carbon arc cutting electrode of this invention is capable of sustaining a higher combustion temperature, having a longer life, and generating lower levels of noise relative to conventional exothermic and air-carbon-arc cutting rods.
