• Exothermic Electrodes Oxygen Requirements Exothermic Electrodes Oxygen Requirements. Exothermic cutting consumes a large volume of oxygen; therefore, a 3/8-inch inside diameter oxygen hose is required to maintain sufficient volume. The hose size is important because it is the oxygen volume together with heat that does the cutting while the pressure blows the slag away.... Read more >>
  • Exothermic Electrodes : Trouble Shooting Trouble Shooting Exothermic Electrodes. Oxy-arc cutting, especially exothermic cutting relies on an unobstructed oxygen flow to be most effective. With inadequate oxygen flow, the rod will burn but not produce the desired cutting effect. Since the actual cutting result is derived from the volume of oxygen reaching the target, any...

  • Exothermic Electrodes Exothermic Electrodes The BROCO Ultrathermic electrode consists of seven small rods inside a thin steel tube. One of the seven rods is a special alloy that will burn independently after an arc is struck and oxygen is flowing through the tube. The remaining six rods are made of mild steel.... Read more >>
