描述
特性：
LKE-7018-A1 is an iron powder low hydrogen type electrode for 490N/mm² high tensile steel. It provides high welding efficiency due to the addition iron powder. The weld metal contains 0.5% Mo.
應用：
it is suitable for chemical plants, petroleum refinery plants and other casting steels.
使用注意事項：
1.Dry the electrodes at 350-400°C for 60 minutes before use.
2.Take the backstep method at the arc starting.
3.Keep the arc as short as possible.
