Applications
For 520-570 N/mm2 High Tensile Steel of ships, machinety and bridges.
Notes on usage
(1) Dry the electrodes at 300-350°C for 30-60 minutes before use.
(2) Take the backstep method or strike the arc on a small steel plate prepared to prevent blowholes at the arc starting.
(3) Keep the arc as short as possible.
