Description: J556 is a low alloy steel electrode with low hydrogen potassium type coating. Both AC and DC can be used, and can be welded in all positions. The performance stability of AC welding is slightly inferior to that of direct welding. Application: Used for welding medium carbon steel and low alloy steel structures such as Q390.
