The conditions forming the electrolytic cell constitute the conditional DC power supply of the electrolytic cell. Two electrodes connected to the positive pole of the power supply. The positive electrode connected to the positive pole of the power supply is called the anode and the negative pole of the power supply, the electrode connected to the negative pole is called the anode, and the electrode connected to the negative pole of the power supply is called the cathode. It is called cathode. Electrolyte solution or molten electrolyte.

Graphite rod is a non-metallic product. As a necessary cutting consumable before welding in the carbon arc air gouging cutting process, it is made of carbon, graphite and appropriate adhesive by extrusion forming, baking and rotating at 2200 ℃, and then plating a layer of copper. It has high temperature resistance, good conductivity, and is not easy to break. It is suitable for cutting metal into the required shape.
