Product Description

J421X is rutile-based carbon steel electrode that is specially designed for downward welding. It has good welding usability that enables it to operate on AC/DC and perform all-position welding, the slag removal is easy and to have a nice bead appearance. Its characteristic of easy operation gives it easy striking and re-striking.
It is suitable for welding zinc-coated steel plates and carbon steel plates that are used in shipbuilding. It is especially suitable for performing downward welding and intermittent welding on the thin plates.
