J421Fe

According with GB E4313
Corresponding with AWS E6013

Introduction: J421Fe is a kind of carbon steel electrode with iron powder titania type coating. AC/DC. All-position welding. It has excellent welding performance and is almost spatter-free. It has easy re-ignition, good slag detachability, smooth welding appearance

Applications: Suitable for welding general low-carbon steel structures, especially suitable for welding small size thin plates, intermittent welding with short weld heads and cosmetic welding that requires smooth weld beads.
