ISO 2560-B-E 49 16 A
Purpose:It is applied in welding medium-carbon steel and low-alloy structures such as 16Mn, 09Mn2Si, 09Mn2V and the steels used in shipbuilding such as A, B, D, E.
Specification:J506 is low-hydrogen potassium coated carbon steel electrode. It has very good welding usability that enables it to operate on AC/DC, performs all-position welding, has stable arc, removal of slag is easy and has low spatter. The deposited metal has good mechanical performance and crack-resistance

Notes:
1. The electrode must be preheated at the temperature of 350°C for 1 hour. Preheat the rod whenever it is used.
2. The impurities such as rust, oil stains and moisture must be cleared off of the work piece.
3.Short arc is required to perform welding. Narrow weld path is preferred.
