1,j421 is the most popular carbon steel welding rod with high titania potassium type coating.
2,It is able to provide excellect welding performance and satisfactory weld can be obtained in all position.
3,It is widely used in ordinary tensile strength mild steel stuctures especially suitable foe intermittent welding to sheet steel and small work pieces as well as cosmetic welding with smooth and shiny appearance.
4,the slag is fluid and when hardened it is compact and easy to remove.
Notes: Use the former generally does not require baking, such as welding rod wet damp conditions can bake 30-60 minutes at 100 °C
