Description: J421X is a high-titanium-potassium-coated electrode for carbon steel welding applications. It can operate in a vertical-down position, and suitable for all-position welding with excellent welding performances, and can be used for both AC and DC. The weld is smooth and neat. The arc is stable and easy to re-strike, slag can be easily removed. Application: It applies to welding ship carbon steel and galvanized steel plate as well, in particular, applies welding of the thin plate in a vertical-down position and discontinuous welding application.
