Description:
1. Name: AWS E7018
2. H.S. Code: 83113000
3. Available size: 2.5*300/350mm; 3.2*350mm; 4.0*350/400mm, 5.0*500mm
4. It is used on both AC and DC in all position.
5. It has excellent welding performance.
6. The arc is stable and the splash is small.
7. As the coating contains iron powder, it has highly efficient welding and can reduce welding layers.
8. It is an excellent carbon steel electrode with iron powder low hydrogen potassium coating.

Package:
Packing in 2.5kgs/box, 8boxes per carton. 5kgs/box, 4boxes per carton .GW: 22.2KG, NW: 20KG . 21-24 pallets/20ft container
Note:
1. The electrodes must be baked under 350°C for an hour before welding.
2. The rust,the oil stains and water on the surfaces of the welded parts should be cleared away
3. short arc operation is required when welding.Narrow welding track is proper.
