General Description

AS R-145 is a rutile-cellulosic type coated electrode with medium recovery. It can be used in all positions including vertical downwards position. It is easy to bend electrode, this property brings great convenience to reach the welding groove in difficult-to-reach areas. Arc stability is high. Especially the thin sheets can be welded easily. It gives uniform and smooth weld beads with easy slag removal. It is very easy to strike and re-strike.
