Rutile Type Electrode

ISO 2560-B-E4303 A

GB/T 5117 E4303

APPLICATIONS:

Used for welding important low-carbon steel structures and low-alloy steel structures with low strength grades, such as Q235, 09MnV, 09Mn2, and etc.

CHARACTERISTICS:

J422 is a rutile type electrode. Can be welding by both AC & DC power source and can be for all-position. It have excellent welding performance as stable arc, little spatter, easy slag removal and reignition-ability etc.
