For the partition ratio of the partition plate 103, it is recommended that the lower chamber 101 is larger than the upper chamber 102.

The preferred choice is a 1 to 5 ratio of the space in the upper chamber 102 to the space in the lower chamber 101. Wherein the first power frequency transformer 301 is disposed in the upper chamber 102, and the control board 201 and the second power frequency transformer 302 are disposed in the lower chamber 101.

Therefore, the heating value of the second power frequency transformer 302 is larger than that of the first power frequency transformer 301. Since the heating value of the second power frequency transformer 302 is larger than that of the first power frequency transformer. Thus, the heat dissipation requirement of the second power frequency transformer 302 is greater than that of the first power frequency transformer 301.

The carbon fiber brush 804 serves to brush the weld path, and the metal conductive tube 801 serves to connect the carbon fiber brush 804 with the grip portion 800. Wherein the power transmission line 412 applies an electrolytic voltage to the metal conductive pipe 801. Moreover, since the carbon fiber brush 804 has a good conductivity, an electrolytic voltage is applied to the weld bead through the carbon fiber brush 804. Electrolytic reaction is carried out with the welding bead (workpiece) under the combined action of the electrolytic voltage and the electrolyte, so as to realize rust removal. Carbon fiber refers to a high strength, high modulus fiber having a carbon content of 90% or more. High temperature resistant living in the first place of all chemical fibers.
