The way I saw it done, the spot welder was actuated with a pedal. The work was positioned over the copper strip (which acted as the ground) and the pedal would be stepped on as the wheel was rolled along the top of the material. In this way they implemented a neat line of spot welds which neatly welded screen to sheet metal.Web
