Type of Current: Direct Current Electrode Positive (DCEP) or AC
Recommended Welding Techniques:
-
Arc Length: Less than half the diameter of the electrode
-
Flat: Angle electrode 10° - 15° from 90°
-
Horizontal: Angle electrode slightly toward top plate
-
Vertical-Up: Use weaving technique
-
Vertical-Down: Not recommended
-
Overhead: Use slight weaving motion within puddle
-
Storage: To ensure a low hydrogen weld deposit, storage in an oven at 220°F to 350°F (104°C to 117°C) is recommended.
- Reconditioning: If exposed to atmosphere for extended periods, the electrode should be reconditioned for one hour at 575°F (302°C).
