Welding electrode AWS E7018 IS iron powder low-hydrogen potassium coated carbon steel type electrode.it can be operated in all postion welding on both AC and DC.the weld is neat and smooth with fewer spatters;its molten depth is well situated.the unique character of the electrode is that iron powder included in the coating,so the welding layer reduced Notes: 1. electrodes must be baked for 1 hour at 350-380°c before welding operation. 2. it is essential to clean up rusty,oil scate,water and impurities on welding parts. 3. short arc operation is required when welding.Narrow welding track is proper.
