Product Description

                                         Carbon Steel Welding Electrodes 
                                                             
 AWS E7018(GB E5018)

Description:
E7018(J506Fe) is an iron powder low hydrogen potassium electrode.
It is used on both AC and DC in all position. As the coating contains iron powder, it that highly efficient welding and can reduce welding layers.
Application:
It is suitable for welding carbon structure and low alloy steel structure, such as 16Mn, etc.

NOTES:
1.  Electrodes must be baked for 1 hour at 350°C before welding operation.
2.  It is essential to clean up rusty,oil scale,water and impurities on welding parts.
3.  Short arc operation is required when welding.  Narrow welding track is proper.
4. Electrode is as positive pole when oprarion on DC.
