Mild Steel Plate (Zn Plating) +Aluminium

Guideline of the Weldability of the Material and Electrode Material

Weldability Acceptable
Upper Electrode Cu-Cr-Zr (Equivalent to RWMA-2)
Lower Electrode Cu-Cr-Zr (Equivalent to RWMA-2)
Special Note

Not enough welding strength.

Generating a stick instead of a nugget.

Coating has a chance to melt or burn.
