General Description

AS R-143 is a heavily coated rutile electrode. As its basic component quantity is higher than  AS R-116, weld metal properties are superior accordingly. Weld metal has a high resistance to cracking. The slag is easy to remove, and it gives high quality, smooth and excellent weld beads. It is easy to strike and re-strike and thus an ideal, easy to use electrode
