Resistance seam welding process is used the heat generated from the resistance to the flow of current. This heat is used to obtain the weld. Seam welding process requires continuous flow of current. Hence large current consumption is one of the drawback of this process, which is try to remove by make a small machine for LAB of collages. The objective of this project is to reduce the power consumption of the collages by limiting the current usages of seam welding machine.
