Which process is associated with the removal of molten metal in Air Carbon Arc Cutting?

  1. Electric discharge

  2. Gas flow

  3. Jet of air

  4. Friction heat

The correct answer is: Jet of air

The process associated with the removal of molten metal in Air Carbon Arc Cutting involves a jet of air. Air Carbon Arc Cutting is a process where an electric arc is created between a carbon electrode and the workpiece, generating intense heat that melts the metal. This molten metal is then blown away from the cutting area by a high-velocity jet of air. This method is particularly effective for cutting thick materials and producing clean edges, as the force of the air jet not only removes the molten metal but also helps to prevent slag formation. The efficiency of the jet of air in removing the molten metal is critical to the success of this cutting process.
