Air Carbon-arc Gouging
  —Gouging carbon electrode for gouging torch.
  Air carbon-arc gouging/Air carbon-arc cutting

Carbon arc gouging is often used to remove material before welding.

Air carbon-arc gouging, also known as air carbon-arc cutting, is a metal removal process that utilizes the heat generated by an arc between a carbon electrode and the workpiece. Compressed air, directed through outlets in the torch, lifts the molten metal away from the arc, preventing it from solidifying and facilitating smooth metal removal.

Instructions:
  1. Thel electrodes must keep in dry environment, if it is affected with damp must be drying before use.
  2. When using for the direct current, the electrodes link to the anode, and task to the cathode.
  3. Keeping steady of working normal air pressure.
Caution:
  • Electrodes must be kept dry. Wet electrodes can flake, or splinter and are dangerous. If electrodes become wet, bake at 300°F for 10 hours before using.
