Special arrangements have been proposed for the polishing of individual portions of the surface and, in particular, for the finishing of weld seams. One of these arrangements takes the form of a special contact head which acts as the cathode. It consists of a copper frame with an aperture.

The lower portion of the frame is covered with special fabric, which is clamped down upon the upper surface of the frame by means of the plate. The negative terminal of the current source is connected to the contact head by means of the contact bolt, and the positive terminal of the current source is connected to the work. 

A continuous supply of the polishing solution is fed through the rubber hose and the pipe to the inside of the cathode from where it flows through the specials fabric and wets the surface of the anode in use, the cathode is moved slowly over the portion of it is required to polish.
