Golden Bridge – J421 (J38.12)
GOLDEN BRIDGE J421 (J38.12) – E6013 Electrode
Description
Introduction：
J421 is a rutile-based carbon steel electrode. It has very good welding usability that enables it to perform all-position welding, operates on AC/DC, removal of slag is easy, has a stable arc, and also has a very good bead appearance. It is easy to operate, which makes re-striking the arc easy.
It is suitable for welding structures made of low carbon steel, performs very well in welding thin and small size steel plates, and also has very good performance in the situation that requires a nice and clean bead appearance.
