Z308 is a cast iron electrode with a pure nickel core and a strong reducing graphite coating. It can be used for both AC and
DC. When welding, the arc is stable, the operation is convenient, and the weldment can be preheated. It is an electrode with
better comprehensive performance such as crack resistance, machinability, and weld strength among cast iron cold welding
electrodes.
