Main Applications：

Z308

According with GB EZNi-1
Corresponding with AWS ENi-C1

Introduction: Z308 is a kind of cast iron electrode with pure nickel core wire and strong reducibility graphite type coating. When welding, the preheating of the weldments can be left out. It has excellent crack-resistance and machinability. Due to the expensive nickel, it can only be selected when other kinds of electrodes are not suitable. AC/DC.

Uses: Used for repair welding on thin cast iron pieces and machined surfaces, such as some key gray cast iron pieces like engine bearers, guide rails of machine tools, pinion stands, etc.
