>High Tensile Steel
LC-300
LC-300 is the most widely used low hydrogen type covered electrode for all positionwelding of 50kgf/mm2 class high tensile strength steels.X-ray soundness and mechanical properties of the weld metal are excellent. The usabilitiessuch as arc smoothness, slag removal and bead appearance are good.

| Characteristics | LC-300 is the most widely used low hydrogen type covered electrode for all position welding of 50kgf/mm2 class high tensile strength steels. X-ray soundness and mechanical properties of the weld metal are excellent. The usabilities such as arc smoothness, slag removal and bead appearance are good. |
| Notes on usage | (1) Dry the electrodes at 300~350℃ for 30~60 minutes before use. (2) Adopt the backstep method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting. (3) Keep the arc as short as possible. |
